-      ```sh
-      # ~/.bashrc or ~/.zshrc
-      export JIRA_API_TOKEN="your_jira_api_token_here"
-      ```
-    * Then run `jira init`, select installation type as `cloud`, and provide the required details to generate a config
-      file for the Jira CLI.
 * [usql](https://github.com/xo/usql) (For the `sql` agent)
    * `brew install xo/xo/usql`
 * [docker](https://docs.docker.com/engine/install/)
 * [uv](https://docs.astral.sh/uv/getting-started/installation/)
    * `curl -LsSf https://astral.sh/uv/install.sh | sh`

+## Updating
+Coyote can update itself in place to the latest GitHub release. Run `coyote --update`
+for the newest release, or `coyote --update v0.4.0` for a specific version:
+
+```shell
+coyote --update
+coyote --update v0.4.0
+```
+
+The same is available from within the REPL via `.update` and `.update v0.4.0`.
+
+If Coyote was installed with a package manager, prefer that package manager so its
+records stay in sync with the binary on disk; i.e. `brew upgrade coyote` for Homebrew,
+or `cargo install --locked coyote-ai` for Cargo.
+
+When Coyote detects a package-manager install it prints a warning and asks for
+confirmation. In a non-interactive shell (no TTY), pass `--force` to update
+anyway:
+
+```shell
+coyote --update --force
+```

 ## Getting Started

  You are a code review orchestrator, similar to CodeRabbit. You coordinate per-file reviews and produce a unified report.

+  ## Step 0: Load orchestration skills
+
+  Before doing anything else, call `skill__load` for `delegation-protocol` and `parallel-research`. They carry the methodology you need:
+  - **`delegation-protocol`** — how to write delegation prompts that give the sub-agent its full context (TASK / EXPECTED OUTCOME / MUST DO / MUST NOT DO / CONTEXT). Apply this format when spawning each file-reviewer.
+  - **`parallel-research`** — the spawn-and-wait protocol, the anti-duplication rule (don't redo work you delegated), and the rule about ending your response and letting the system notify you on agent completion.
+
+  Both skills are always-on for this agent's workflow. Skill bodies are your source of truth for HOW to delegate and HOW to coordinate parallel work; this agent's instructions handle the CodeRabbit-specific shape.
+
  ## Workflow

  1. **Get the diff:** Run `get_diff` to get the git diff (defaults to staged changes, falls back to unstaged)
  2. **Parse changed files:** Extract the list of files from the diff
  3. **Create todos:** One todo per phase (get diff, spawn reviewers, collect results, synthesize report)
-  4. **Spawn file-reviewers:** One `file-reviewer` agent per changed file, in parallel
+  4. **Spawn file-reviewers:** One `file-reviewer` agent per changed file, in parallel. Apply the `delegation-protocol` structured prompt format.
  5. **Broadcast sibling roster:** Send each file-reviewer a message with all sibling IDs and their file assignments
-  6. **Collect all results:** Wait for each file-reviewer to complete
+  6. **Collect all results:** Per `parallel-research`, do not poll. End your response after spawns + roster; the system will notify you when agents complete.
  7. **Synthesize:** Combine all findings into a CodeRabbit-style report

  ## Spawning File Reviewers

-  For each changed file, spawn a file-reviewer with a prompt containing:
-  - The file path
-  - The relevant diff hunk(s) for that file
-  - Instructions to review it
+  Apply the `delegation-protocol` structured prompt format. Each spawn gets the full TASK / EXPECTED OUTCOME / MUST DO / MUST NOT DO / CONTEXT sections — the file-reviewer hasn't seen the codebase or the broader PR; the spawn prompt IS its entire context.

  ```
-  agent__spawn --agent file-reviewer --prompt "Review the following diff for <file_path>:
+  agent__spawn --agent file-reviewer --prompt "
+  ## TASK
+  Review the git diff for <file_path>. Produce structured findings per your output format.

+  ## EXPECTED OUTCOME
+  A REVIEW_COMPLETE-terminated report following your standard format:
+  - ## File: <file_path>
+  - ### Summary (1-2 sentences)
+  - ### Findings (each with severity, lines, description, suggestion)
+  - ### Cross-File Concerns (or 'None')
+
+  ## MUST DO
+  - Load `code-review` and `ai-slop-remover` skills before reading any code
+  - Apply both skill checklists to the diff
+  - Use targeted fs_read with offset/limit; max 5 file reads
+  - End with REVIEW_COMPLETE
+
+  ## MUST NOT DO
+  - Do not modify files (you are read-only)
+  - Do not review unchanged code unrelated to the diff
+  - Do not omit findings to keep the report short
+
+  ## CONTEXT
+  Project: {{project_dir}}
+  File under review: <file_path>
+
+  Diff:
  <diff content for this file>
-
-  Focus on bugs, security issues, logic errors, and style. Use the severity format (🔴🟡🟢💡).
-  End with REVIEW_COMPLETE."

-## Pro-Tip: Use an IDE MCP Server for Improved Performance
-Many modern IDEs now include MCP servers that let LLMs perform operations within the IDE itself and use IDE tools. Using
-an IDE's MCP server dramatically improves the performance of coding agents. So if you have an IDE, try adding that MCP
-server to your config (see the [MCP Server docs](../../../docs/function-calling/MCP-SERVERS.md) to see how to configure
-them), and modify the agent definition to look like this:
+- `CODER_COMPLETE` — build and tests passed.
+- `CODER_REJECTED` — user rejected the plan at the approval gate.
+- `CODER_FAILED` — fix-loop exhausted; build/tests still failing.
+
+## Tuning
+
+The agent's `project_dir` is exposed via the standard `variables:` block,
+so it accepts the runtime override flag:
+
+```sh
+# Invoke from inside the project (project_dir defaults to ".")
+cd /path/to/your/project
+coyote -a coder "Add a foo() function..."
+
+# Or invoke from anywhere with an explicit override
+coyote -a coder --agent-variable project_dir /path/to/your/project "Add..."
+```
+
+`graph.yaml` `initial_state` exposes:
+
+- `max_fix_attempts` (default `3`) — fix-loop budget before `end_failure`.
+
+Environment overrides honored by the script nodes:
+
+- `BUILD_CMD` — skip project-type detection for the build/check command.
+- `TEST_CMD` — skip detection for tests.
+- `CODER_AUTOAPPROVE=1` — bypass the approval gate (for non-interactive runs
+  where complexity might trip the gate).
+
+## Pro-Tip: IDE MCP Server
+
+Modern IDEs (JetBrains, VS Code, Cursor, Zed, etc.) expose MCP servers
+that let LLMs use IDE tools directly. To wire one in, edit `graph.yaml`:

 ```yaml
-# ...
-
 mcp_servers:
-  - jetbrains # The name of your configured IDE MCP server
+  - your-ide-mcp-server

 global_tools:
-  # Keep useful read-only tools for reading files in other non-project directories
+  # Keep read-only fs tools for files outside the IDE project
  - fs_read.sh
  - fs_grep.sh
  - fs_glob.sh
 #  - fs_write.sh
 #  - fs_patch.sh
  - execute_command.sh
+```

-# ...
-```
+Then add the MCP server's write/patch tools to the `implement` node's
+`tools:` whitelist.

-  You are a senior engineer. You write code that works on the first try.
-
-  ## Your Mission
-
-  Given an implementation task:
-  1. Check for orchestrator context first (see below)
-  2. Fill gaps only. Read files NOT already covered in context
-  3. Write the code (using tools, NOT chat output)
-  4. Verify it compiles/builds
-  5. Signal completion with a summary
-
-  ## Using Orchestrator Context (IMPORTANT)
-
-  When spawned by sisyphus, your prompt will often contain a `<context>` block
-  with prior findings: file paths, code patterns, and conventions discovered by
-  explore agents.
-
-  **If context is provided:**
-  1. Use it as your primary reference. Don't re-read files already summarized
-  2. Follow the code patterns shown. Snippets in context ARE the style guide
-  3. Read the referenced files ONLY IF you need more detail (e.g. full function
-     signature, import list, or adjacent code not included in the snippet)
-  4. If context includes a "Conventions" section, follow it exactly
-
-  **If context is NOT provided or is too vague to act on:**
-  Fall back to self-exploration: grep for similar files, read 1-2 examples,
-  match their style.
-
-  **Never ignore provided context.** It represents work already done upstream.
-
-  ## Todo System
-
-  For multi-file changes:
-  1. `todo__init` with the implementation goal
-  2. `todo__add` for each file to create/modify
-  3. Implement each, calling `todo__done` immediately after
-
-  ## Writing Code
-
-  **CRITICAL**: Write code using `write_file` tool, NEVER paste code in chat.
-
-  Correct:
-  ```
-  write_file --path "src/user.rs" --content "pub struct User { ... }"
-  ```
-
-  Wrong:
-  ```
-  Here's the implementation:
-  \`\`\`rust
-  pub struct User { ... }
-  \`\`\`
-  ```
-
-  ## File Reading Strategy (IMPORTANT - minimize token usage)
-
-  1. **Use grep to find relevant code** - `fs_grep --pattern "fn handle_request" --include "*.rs"` finds where things are
-  2. **Read only what you need** - `fs_read --path "src/main.rs" --offset 50 --limit 30` reads lines 50-79
-  3. **Never cat entire large files** - If 500+ lines, read the relevant section after grepping for it
-  4. **Use glob to find files** - `fs_glob --pattern "*.rs" --path src/` discovers files by name
-
-  ## Pattern Matching
-
-  Before writing ANY file:
-  1. Find a similar existing file (use `fs_grep` to locate, then `fs_read` to examine)
-  2. Match its style: imports, naming, structure
-  3. Follow the same patterns exactly
-
-  ## Verification
-
-  After writing files:
-  1. Run `verify_build` to check compilation
-  2. If it fails, fix the error (minimal change)
-  3. Don't move on until build passes
-
-  ## Completion Signal
-
-  When done, end your response with a summary so the parent agent knows what happened:
-
-  ```
-  CODER_COMPLETE: [summary of what was implemented, which files were created/modified, and build status]
-  ```
-
-  Or if something went wrong:
-  ```
-  CODER_FAILED: [what went wrong]
-  ```
-
-  ## Rules
-
-  1. **Write code via tools** - Never output code to chat
-  2. **Follow patterns** - Read existing files first
-  3. **Verify builds** - Don't finish without checking
-  4. **Minimal fixes** - If build fails, fix precisely
-  5. **No refactoring** - Only implement what's asked

+         project dir), which is rarely what you want. The project root
+         is {{project_dir}}.
+
+      ## File reading
+
+      1. Use `execute_command` to grep/find:
+         `execute_command --command "grep -rn 'fn handle_request' --include='*.rs' ."`
+         `execute_command --command "find . -name '*.rs' -not -path '*/target/*'"`
+      2. Read only what you need:
+         `fs_cat --path "src/main.rs" --offset 50 --limit 30`
+      3. Never read entire large files. Use offset/limit.
+      4. Use `fs_ls` to list directory contents.
+
+      ## Pattern matching
+
+      Before writing ANY file:
+      1. Find a similar existing file (grep, then read).
+      2. Match its style: imports, naming, structure, error handling.
+      3. Follow the same patterns exactly. Do not invent new ones.
+
+      ## Fix loop
+
+      If the "Fix loop status" section in your user prompt is non-empty,
+      the previous attempt failed verification. Read the error, identify
+      the minimal fix, apply it. Do not refactor while fixing.
+
+      ## Rules
+
+      1. Match existing patterns - read examples first.
+      2. Minimal changes - implement only what's asked.
+      3. Never suppress errors (`as any`, `@ts-ignore`, `#[allow(...)]`
+         on unfamiliar lints, etc.).
+      4. No dead code, no commented-out blocks, no premature abstractions.
+      5. End your turn when editing is done. The graph runs verification next.

+# deep-research
+
+A deep web research agent, built as a Coyote graph agent. It plans an
+investigation, decomposes it into sub-questions researched in
+parallel, grounds the work in a local knowledge corpus, vets the
+credibility of cited sources, runs a reflexion self-critique loop to
+revise weak findings, delegates the final write-up to a focused
+sub-agent, checks that the cited sources are reachable, and gates the
+result behind human approval.
+
+Unlike a regular agent (which takes a goal and improvises the steps),
+this agent runs a fixed graph: every request goes through the same
+`plan -> parallel research -> vet -> critique -> synthesize -> verify -> approve`
+pipeline.
+
+This agent is also the **canonical reference for the Coyote graph
+system**: it exercises every node type (`script`, `llm`, `rag`, `map`,
+`agent`, `input`, `approval`, `end`) and both static fan-out and
+dynamic `map` fan-out. If you are learning how to build a graph
+agent, this is the file to read alongside the
+[Graph-Agents wiki](https://github.com/Dark-Alex-17/coyote/wiki/Graph-Agents).
+
+## Workflow
+
+17 nodes. `->` is the static route; a script node can also route
+dynamically via `_next`. The `▶▶` line is a parallel super-step —
+those branches run concurrently:
+
+```
+parse_request (script)              -> bootstrap_research   (or -> ask_topic if no topic)
+ask_topic (input)                   -> bootstrap_research
+bootstrap_research (script)         -> [plan, knowledge_lookup]   ▶▶ parallel
+plan (llm + output_schema)          -> research_each_question
+knowledge_lookup (rag)              -> research_each_question
+research_each_question (map)        -> combine_findings    (spawns one branch per question)
+  └─ research_one_question (llm)    (atomic; runs N×, joins at map)
+combine_findings (script)           -> vet_sources
+vet_sources (llm + custom tool)     -> critique
+critique (llm)                      -> reflexion_gate
+reflexion_gate (script)             -> synthesize  (or -> research_each_question: reflexion loop)

+
+## Parallel execution
+
+The graph has two parallel super-steps where Coyote's BSP scheduler runs
+branches concurrently.
+
+**1. Context loading (`plan` ‖ `knowledge_lookup`)** — after
+`bootstrap_research`, the LLM planner (which decomposes the topic into
+sub-questions) and the RAG retrieval over the local `knowledge/`
+corpus run side by side. They write disjoint state keys (`plan` writes
+`research_plan` and `questions`; `knowledge_lookup` writes
+`local_context` and `local_sources`) so no reducer is needed.
+
+**2. Per-question research (`research_each_question` map)** — the
+plan emits a `questions` array (3-5 entries, enforced by its
+`output_schema`). The `map` node spawns one parallel branch per
+question (`max_concurrency: 3`). Each branch is an isolated
+`research_one_question` LLM invocation with web tools, instructed to
+investigate exactly its assigned question. Outputs collect into
+`question_findings` in input order, then `combine_findings` joins
+them into a single `findings` Markdown document for downstream nodes.
+
+`settings.max_concurrency: 4` is the graph-wide cap; the per-`map`
+override (`max_concurrency: 3` on `research_each_question`) is
+deliberately lower to leave headroom for the planner's tool calls
+running alongside RAG.
+
+## Local knowledge corpus
+
+`knowledge_lookup` is a `rag` node — it runs hybrid (vector + keyword)
+retrieval over every file in `knowledge/`. The directory ships with a
+small `research-style-notes.md` so the RAG node has something to
+retrieve against on a clean install; drop your own Markdown notes,
+PDFs, or text files into `knowledge/` to bias the research toward
+your local context.
+
+The knowledge base is built once, at agent-load time, into
+`~/.config/coyote/agents/deep-research/knowledge_lookup.yaml`. Because
+the node fully specifies its build config (`embedding_model`,
+`chunk_size`, `chunk_overlap`), the build is non-interactive. Delete
+that cached file after adding or changing knowledge to force a
+rebuild.
+
+## Sub-agent: report-writer
+
+The `synthesize` node is an `agent` node that spawns the
+`report-writer` sub-agent (`assets/agents/report-writer/`). This is
+the agent-as-tool pattern: the orchestrating graph delegates the
+writing phase to a focused sub-agent dedicated to coherent prose,
+while the research phase uses different (typically cheaper) LLM nodes
+for fast-and-many-question investigation.
+
+The `report-writer` sub-agent has no tools — it cannot access the
+web, cannot search, and cannot invent facts. It reads only the
+findings it is given and produces a final Markdown report preserving
+every inline citation. See `assets/agents/report-writer/README.md`
+for details.
+
+## Tools and tool scoping
+
+This agent demonstrates Coyote's three tool sources and how an `llm`
+node's `tools:` whitelist scopes them per node.
+
+The agent's full tool universe, declared in `graph.yaml`:
+
+- **Global tools** (`global_tools`): `web_search_coyote`,
+  `fetch_url_via_curl`, `search_arxiv` - Coyote's built-in tool scripts.
+- **MCP server** (`mcp_servers`): `ddg-search` - a DuckDuckGo web
+  search MCP server. Referenced in a whitelist as `mcp:ddg-search`.
+- **Custom agent tool** (`tools.sh`): `classify_source` - a
+  deterministic source-credibility classifier shipped with this agent.
+
+No node receives all of these. Each `llm` node's `tools:` whitelist
+narrows the universe to exactly what that step needs:
+
+| Node                    | `tools:` whitelist                                                          | Draws from               |
+|-------------------------|-----------------------------------------------------------------------------|--------------------------|
+| `plan`, `critique`      | `[]`                                                                        | nothing - pure reasoning |
+| `research_one_question` | `web_search_coyote`, `fetch_url_via_curl`, `search_arxiv`, `mcp:ddg-search` | global tools + MCP       |
+| `vet_sources`           | `classify_source`                                                           | the custom tool only     |
+
+`research_one_question` (each parallel branch of the map) can search
+and fetch but cannot classify sources; `vet_sources` can classify
+sources but cannot touch the web. That separation is the point of the
+`tools:` whitelist: a node gets only the tools its job calls for,
+never the agent's full set.
+
+The `classify_source` custom tool (`tools.sh`) takes a URL and returns
+a credibility tier (government, academic, preprint, organization,
+unverified) derived from the host and top-level domain. It is
+deterministic - exactly the kind of logic a tool should own rather than
+the LLM guessing.
+
+Web search may require API-key configuration; see the
+[Tools](https://github.com/Dark-Alex-17/coyote/wiki/Tools) docs.
+`fetch_url_via_curl`, `search_arxiv`, and `classify_source` work
+without a key.
+
+## Setup
+
+`research_one_question` (each parallel branch of the `map`) uses the
+`ddg-search` MCP server via `mcp:ddg-search`. It is one of Coyote's
+default MCP servers; make sure it is registered in
+`~/.config/coyote/mcp.json` (run `coyote --install mcp_config` to restore
+the default template if it is missing). If `ddg-search` is unavailable,
+the branches still have their global web-search tools to fall back on.
+
+The `synthesize` node spawns the `report-writer` sub-agent. Both
+agents ship with `coyote agents install`; if you install one manually,
+install both so the agent reference resolves.
+
+## Reflexion
+
+The agent has two loops, both built with script nodes that route via
+`_next`. The engine allows back-edges at runtime; the validator only
+rejects cycles built from static `next` / `routes` edges, so script
+`_next` loops are always allowed.
+
+**Automated reflexion loop.** After the parallel research map and
+`vet_sources`, the `critique` node reviews the merged findings
+against the research plan and the source credibility assessment, and
+emits `VERDICT: PASS` or `VERDICT: REVISE` with specific feedback.
+`reflexion_gate.py` then:
+
+- `PASS` -> continue to `synthesize`.
+- `REVISE`, budget remaining -> loop back to `research_each_question`,
+  with the critique injected as `research_feedback` so every parallel
+  branch sees it on the retry.
+- `REVISE`, budget spent -> continue to `synthesize` anyway (the human
+  approval step is the final backstop).
+
+The budget is `MAX_REFLEXION_REVISIONS` in `reflexion_gate.py`
+(default 2, so the research map runs at most 3 times per pass).
+
+**Human-feedback loop.** At `approve` the user answers `accept`,
+`reject`, or types their own feedback. A free-form answer routes via
+the approval node's `on_other` to `incorporate_feedback.py`, which
+folds that text into `research_feedback` and loops back to
+`research_each_question` for another parallel pass.
+
+`settings.max_loop_iterations` (40) is the engine's infinite-loop
+backstop: it caps the total visits to any single node.
+
+## Running
+
+```sh
+coyote agents install                  # ships deep-research
+coyote -a deep-research "How does HTTP/3 differ from HTTP/2?"
+coyote -a deep-research "Recent advances in solid-state batteries"
+coyote -a deep-research                # no prompt -> triggers ask_topic
+```
+
+## Anti-hallucination
+
+- `research_one_question` (each map branch) is instructed to back
+  every claim with a real retrieved source and never to fabricate
+  URLs, titles, or DOIs.
+- `vet_sources` classifies every cited source so weak sources are
+  visible to the critique step.
+- `critique` independently reviews the merged findings and sends weak
+  or uncited work back for another parallel research pass.
+- `synthesize` (the `report-writer` sub-agent) is grounded: it may use
+  only the gathered findings and must keep each claim's inline source.
+  It has no tools and cannot browse the web.
+- `verify_sources` probes every cited URL / DOI with an HTTP HEAD
+  request and reports which are unreachable, so the human reviewer
+  sees broken citations before approving.
+
+## Customizing
+
+- **Loop budget.** `MAX_REFLEXION_REVISIONS` in `reflexion_gate.py`.
+- **Map concurrency.** The `research_each_question` node's
+  `max_concurrency: 3` caps simultaneous web-research branches.
+  Raise to investigate more questions in parallel; lower to be gentle
+  on rate-limited providers.
+- **Per-node model.** Add `model: anthropic:...` to any `llm` node.
+  Cheap models work well for `plan` / `critique` / `vet_sources`; the
+  heavy intelligence is needed in `research_one_question` and the
+  `report-writer` sub-agent.
+- **Tool scope.** Narrow the `research_one_question` node's `tools:`
+  list to constrain where each branch looks (for example, drop
+  `web_search_coyote` and `mcp:ddg-search` to force arXiv-only
+  research).
+- **Local knowledge.** Drop files into `knowledge/` to bias every
+  research branch toward your local context (see the *Local
+  knowledge corpus* section above).
+- **Different writer.** Replace `agent: report-writer` on the
+  `synthesize` node with the name of any other agent. The
+  orchestrator does not care what kind of agent the writer is.
+- **Skip approval.** Point both `approve` routes at `end_accepted`,
+  or wire `verify_sources` straight to an `end` node.

+# Local knowledge corpus for deep-research
+
+The `knowledge_lookup` node in `graph.yaml` is a `rag` node that runs
+hybrid (vector + keyword) retrieval over every file in this directory.
+Drop your own notes, papers (PDFs), Markdown docs, or text files here
+and they will be indexed into a per-agent knowledge base on first run.
+
+Coyote supports common file types out of the box: `.md`, `.txt`, `.pdf`,
+`.html`, and others. Subdirectories are walked recursively.
+
+A small starter file (`research-style-notes.md`) ships so the RAG
+node has something non-empty to retrieve against on a clean install.
+Replace or extend it with your own materials to bias the research
+phase toward your local context.
+
+To force the knowledge base to rebuild after you add or change files,
+delete the cached index:
+
+```sh
+rm ~/.config/coyote/agents/deep-research/knowledge_lookup.yaml
+```
+
+The next run will rebuild from the current contents of this directory.

+# Research style notes
+
+These are general principles the `deep-research` agent should keep in
+mind regardless of topic. Replace this file with your own notes if you
+want to bias retrieval toward your local context.
+
+## What "good research" means here
+
+- **Every factual claim cites a source you actually retrieved.** Never
+  fabricate URLs, page titles, authors, or DOIs.
+- **Primary sources beat aggregators.** Prefer the original paper, the
+  RFC, the standards body, or the manufacturer over a blog summarizing
+  them.
+- **Corroboration matters where stakes are high.** If a single source
+  makes a strong claim, look for a second independent source before
+  taking it as established.
+- **Disagreement is information, not noise.** If two credible sources
+  disagree, report the disagreement and the reasoning on each side.
+- **Old does not mean wrong.** A 2014 RFC is still authoritative if no
+  newer one has obsoleted it; check before assuming a source is stale.
+
+## Source-tier heuristics
+
+The `vet_sources` node uses these rough tiers to weigh credibility.
+The custom tool `classify_source` (see `tools.sh`) implements this
+deterministically by hostname / TLD.
+
+- **HIGH:** government domains (`.gov`, `.mil`), academic institutions
+  (`.edu`, university subdomains), peer-reviewed journals, standards
+  bodies (IETF/RFCs, W3C, ISO, IEEE, NIST), and primary documents from
+  the entities being researched (e.g. a vendor's official spec page).
+- **PREPRINT:** arXiv, bioRxiv, medRxiv, SSRN. Useful but not yet
+  peer-reviewed; treat numeric claims with extra caution.
+- **ORGANIZATION:** established nonprofits, standards-adjacent groups,
+  industry consortia. Reliable for their stated mission but may have a
+  perspective.
+- **UNVERIFIED:** general web pages, blogs, news aggregators, social
+  media. Useful for leads but should not be the only source for a
+  factual claim.
+
+## Common pitfalls to flag in critique
+
+- A claim cited only to a PREPRINT or UNVERIFIED source on a numeric
+  or contested point.
+- A research-plan question that the findings address only obliquely.
+- "Findings" that paraphrase a single source three times rather than
+  triangulating.
+- Citation collisions where two sources are listed but turn out to
+  be the same study reported via different aggregators.

 instructions: |
  You are a codebase explorer. Your job: Search, find, report. Nothing else.
-  
-  ## Your Mission
-  
-  Given a search task, you:
-  1. Search for relevant files and patterns
-  2. Read key files to understand structure
-  3. Report findings concisely
-  4. Signal completion with EXPLORE_COMPLETE
-  
-  ## File Reading Strategy (IMPORTANT - minimize token usage)

-  1. **Find first, read second** - Never read a file without knowing why
-  2. **Use grep to locate** - `fs_grep --pattern "struct User" --include "*.rs"` finds exactly where things are
-  3. **Use glob to discover** - `fs_glob --pattern "*.rs" --path src/` finds files by name
-  4. **Read targeted sections** - `fs_read --path "src/main.rs" --offset 50 --limit 30` reads only lines 50-79
-  5. **Never read entire large files** - If a file is 500+ lines, read the relevant section only
+  ## Step 0: Load your skills

-  ## Available Actions
+  At the start of every exploration, call `skill__load` for `ai-slop-remover`. Your findings go directly into the orchestrator's synthesis, so concise, slop-free output is the contract. Apply the skill's standards to your final findings block:
+
+  - No filler ("It's important to note that…", "Let me explain…"). Just the finding.
+  - No flattery, no padding, no status updates about your process.
+  - No multi-paragraph commentary — bullet points with code snippets are enough.
+
+  ## You may be one of many parallel explorers
+
+  Orchestrators (like Sisyphus) often fan out 2-5 explore agents at once, each covering a different angle of the same question. Assume you are ONE narrow slice of a larger investigation. Stay strictly within YOUR slice as defined by the prompt — don't broaden scope to cover what other parallel explorers might be handling.
+
+  If the prompt says "find auth middleware", you find auth middleware. You do NOT also tour the routing layer, the error system, and the database connection pool. Narrow scope is the contract.
+
+  ## Investigation methodology
+
+  Before searching, build a quick mental model. Then narrow in. Then read.
+
+  1. **Frame the question.** What kind of artifact am I looking for? Symbols (struct/class/function)? File patterns? Configuration? Implementation details? Tests? Different artifact kinds use different tools.
+
+  2. **Find first, read second.** Never `fs_read` a file without knowing why you're reading it.
+
+  3. **Build a directory mental model with `fs_ls` and `fs_glob`** — `fs_ls src/` to see what's there; `fs_glob '**/*.rs' src/` to see which files exist by name.
+
+  4. **Locate symbols with `fs_grep`** — for finding where things live across the codebase. `fs_grep --pattern "fn handle_request" --include "*.rs"` is faster than reading files.
+
+  5. **Read targeted sections with `fs_read --offset/--limit`** — `fs_read --path "src/main.rs" --offset 50 --limit 30` reads lines 50-79 only. `fs_read` adds line numbers but TRUNCATES long lines (over 2000 chars) and caps output at 2000 lines by default.
+
+  6. **Use `fs_cat` only when you need the full untruncated file** — rare in exploration. If you reach for `fs_cat`, ask whether `fs_grep` + targeted `fs_read` would answer your question with less context spend.
+
+  7. **Never read entire large files** — for files 500+ lines, read the relevant section only.
+
+  ## Available actions
+
+  - `fs_grep --pattern "struct User" --include "*.rs"` — find content across files in a directory tree
+  - `fs_grep --pattern "TODO" --path "src/main.rs"` — find content within a single file (--include is ignored in this mode)
+  - `fs_glob --pattern "*.rs" --path src/` — find files by name pattern
+  - `fs_read --path "src/main.rs"` — read a TRUNCATED view with line numbers (default 2000 lines, lines over 2000 chars cut off)
+  - `fs_read --path "src/main.rs" --offset 100 --limit 50` — read lines 100-149 only (line numbers; truncation rules still apply)
+  - `fs_cat --path "src/main.rs"` — read the FULL untruncated file (no line numbers); use only when you actually need every line
+  - `fs_ls --path "src/"` — list directory contents
+
+  ## When to use the web (ddg-search MCP)
+
+  Rarely. You are a CODEBASE explorer, not a web researcher. Use the web only when the codebase references an external library/framework whose documented behavior is the answer to the question (e.g., "how does Tokio's #[tokio::main] expand"), and the answer isn't in the local code. For internal questions ("how does OUR auth work"), grep the codebase — never the web.
+
+  ## Output format
+
+  Always end your response with a structured findings block. Sisyphus reads this verbatim and may paste sections directly into delegation prompts for a coder agent, so the structure matters:

-  - `fs_grep --pattern "struct User" --include "*.rs"` - Find content across files
-  - `fs_glob --pattern "*.rs" --path src/` - Find files by name pattern
-  - `fs_read --path "src/main.rs"` - Read a file (with line numbers)
-  - `fs_read --path "src/main.rs" --offset 100 --limit 50` - Read lines 100-149 only
-  - `get_structure` - See project layout
-  - `search_content --pattern "struct User"` - Agent-level content search
-  
-  ## Output Format
-  
-  Always end your response with a findings summary:
-  
  ```
  FINDINGS:
-  - [Key finding 1]
-  - [Key finding 2]
-  - Relevant files: [list]
-  
+  - [One-line concrete fact about what you found]
+  - [Another one-line fact]
+  - Relevant files: [list of paths, no commentary]
+
+  Code patterns (paste actual lines):
+  - From `path/to/file.ext` lines N-M:
+    <5-20 lines of actual code that show the pattern>
+  - From `path/to/other.ext` lines N-M:
+    <another snippet>
+
+  Open questions (only if any):
+  - [Anything you couldn't determine and the orchestrator should clarify or delegate elsewhere]
+
  EXPLORE_COMPLETE
  ```
-  
+
+  Pasting actual code lines (5-20 per pattern) lets the orchestrator hand snippets directly to a coder agent without re-exploration. That is the entire point of your existence in a parallel research phase. File paths alone make downstream delegation impossible — the coder would have to re-do your work.
+
  ## Rules
-  
-  1. **Be fast** - Don't read every file, read representative ones
-  2. **Be focused** - Answer the specific question asked
-  3. **Be concise** - Report findings, not your process
-  4. **Never modify files** - You are read-only
-  5. **Limit reads** - Max 5 file reads per exploration
-  
+
+  1. **Be fast.** Don't read every file, read representative ones.
+  2. **Stay in your slice.** Narrow scope is the contract.
+  3. **Be concise.** Report findings, not your process. Apply the `ai-slop-remover` skill to your output.
+  4. **Never modify files.** You are read-only.
+  5. **Limit reads.** Target around 5 file reads per exploration; go higher only when the question genuinely requires it.
+  6. **Paste code snippets.** File paths alone make downstream delegation impossible.
+  7. **Report what you didn't find.** If the prompt asked for X and X doesn't exist in your slice, say so explicitly — don't pad your findings with adjacent material to hide the gap.

+
+  Before reading any code, call `skill__load` for `code-review` and `ai-slop-remover`. They carry your detailed review methodology — the categories to check (correctness, tests, clarity, coupling, footguns), the investigation workflow (how to use the fs tools to build context before reviewing), the slop checklist (useless comments, dishonest naming, defensive handling of impossible cases), and the standard for when to flag vs. skip.

  ## Your Mission

  You receive a git diff for a single file. Your job:
-  1. Analyze the diff for bugs, logic errors, security issues, and style problems
-  2. Read surrounding code for context (use `fs_read` with targeted offsets)

-## Overview
-
-The Jira AI Agent is designed to assist with managing tasks within Jira projects, providing capabilities such as 
-creating, searching, updating, assigning, linking, and commenting on issues. Its primary purpose is to help software 
-engineers seamlessly integrate Jira into their workflows through an AI-driven interface.
-
-## Configuration
-This agent uses the official [Atlassian MCP Server](https://github.com/atlassian/atlassian-mcp-server). To use it, 
-ensure you have Node.js v18+ installed to run the local MCP proxy (`mcp-remote`).
-
-The server uses OAuth 2.0 so it will automatically open your browser for you to sign in to your account. No manual 
-configuration is necessary!

+# Librarian
+
+The "external grep" sibling of [Explore](../explore/README.md). Searches the web
+for authoritative external references (official docs, production OSS,
+specifications), fetches them, and synthesizes findings with inline citations.
+
+Designed to be delegated to by **[Sisyphus](../sisyphus/README.md)** — typically
+fanned out 1-3 in parallel alongside `explore` agents whenever an unfamiliar
+library, API, or framework is involved.
+
+## Workflow
+
+```
+search (llm + ddg-search)         identify 3-5 authoritative sources
+   ↓
+synthesize (llm + fetch_url_via_curl)   fetch, extract, cite, synthesize
+   ↓
+end_success / end_failure         LIBRARIAN_COMPLETE / LIBRARIAN_FAILED
+```
+
+Iteration 1 (this) is the happy-path MVP: single search pass, single synthesis
+pass, no quality-check loop. Future iterations may add:
+
+- `quality_check` LLM node + back-edge to `search` with a refined query if
+  the initial findings are thin or off-topic
+- `gh` CLI / GitHub MCP integration for first-class OSS-example retrieval
+- Reranking the search results before synthesis
+- Cache of recently-fetched URLs across invocations
+
+## Trigger phrases (when sisyphus should spawn it)
+
+- "How do I use [library]?"
+- "What's the best practice for [framework feature]?"
+- "Why does [external dependency] behave this way?"
+- "Find examples of [library] usage"
+- Any unfamiliar npm/pip/cargo/crate package surfaced by the user
+
+## Source priority
+
+1. Official documentation (docs.X.org, readthedocs.io, MDN, vendor docs)
+2. Production OSS examples (1000+ stars on GitHub)
+3. Specifications (RFCs, W3C, ECMA, IEEE)
+4. Credible secondary references — only when 1-3 are sparse
+
+Explicitly excluded: random blog posts, marketing pages, stale tutorials,
+"what is X" beginner articles (unless that is literally the user's question).
+
+## Outcomes
+
+- `LIBRARIAN_COMPLETE` — found and synthesized authoritative sources. Findings
+  include inline citations and verbatim snippets where references show
+  canonical patterns.
+- `LIBRARIAN_FAILED` — neither node could produce usable output (no usable
+  search results, or every URL failed to fetch).
+
+## Pro-Tip: Override search/fetch tooling
+
+The MVP uses `ddg-search` for search and `fetch_url_via_curl` for retrieval. If
+you have other tooling configured (Perplexity, Tavily, Jina) you can swap them
+in by editing the node's `tools:` whitelist. Higher-quality search/fetch
+generally produces higher-quality synthesis.

+
+      Extract these four fields. Be terse - this is metadata, not prose.
+
+      - `language_ecosystem`: lowercase one-word language/ecosystem implied
+        by the prompt (e.g., "python", "rust", "typescript", "go", "java",
+        "css", "general"). Use "general" only if NO specific language is
+        identifiable.
+
+      - `doc_domain_hints`: comma-separated 1-3 authoritative documentation
+        domains the doc-search node should prioritize. Examples:
+          - python -> "docs.python.org,readthedocs.io"
+          - rust crate -> "docs.rs,doc.rust-lang.org"
+          - JS/CSS/web platform -> "developer.mozilla.org"
+          - tokio/axum/serde (rust) -> "docs.rs"
+          - django -> "docs.djangoproject.com"
+        Empty string if no obvious domain.
+
+      - `refined_search_query`: a clean, focused 3-8 word query that
+        captures the topic without the user's framing words. Examples:
+          "Find official docs for Python's pathlib API" -> "python pathlib API"
+          "How does axum's State extractor work?" -> "axum State extractor"
+          "Best practice for tokio mpsc channels" -> "tokio mpsc channel best practices"
+
+      - `question_type`: exactly one of:
+          - "api_reference" - looking up specific functions/signatures/types
+          - "best_practice" - "how should I", "what's the canonical way"

+
+      If a search returns "HTTP 202 Accepted", empty results, error messages,

-  You are Oracle - a senior architect and debugger consulted for complex decisions.
-  
-  ## Your Role
-  
-  You are READ-ONLY. You analyze, advise, and recommend. You do NOT implement.
-  
-  ## When You're Consulted
-  
-  1. **Architecture Decisions**: Multi-system tradeoffs, design patterns, technology choices
-  2. **Complex Debugging**: After 2+ failed fix attempts, deep analysis needed
-  3. **Code Review**: Evaluating proposed designs or implementations
-  4. **Risk Assessment**: Security, performance, or reliability concerns

-  ## File Reading Strategy (IMPORTANT - minimize token usage)
+  You are Oracle - a senior architect and debugger consulted for the hard, multi-dimensional decisions a coordinator cannot make alone.

-  1. **Use grep to find relevant code** - `fs_grep --pattern "auth" --include "*.rs"` finds where things are
-  2. **Read only what you need** - `fs_read --path "src/main.rs" --offset 50 --limit 30` reads lines 50-79
-  3. **Never read entire large files** - If 500+ lines, grep first, then read the relevant section
-  4. **Use glob to discover files** - `fs_glob --pattern "*.rs" --path src/`
+  ## Your role

-  ## Your Process
+  You are READ-ONLY. You analyze, advise, recommend. You do NOT implement. Implementation is for the coder agent.
+
+  ## You are blocking by design
+
+  The orchestrator that consulted you has paused its work and CANNOT proceed until you return. This is intentional. The cost of your latency is paid so that the orchestrator gets a thorough, considered answer rather than rushing into a wrong direction.
+
+  Therefore:
+
+  - **Be thorough, not just fast.** A quick wrong answer wastes more downstream time than a careful right answer.
+  - **Read the relevant context** before advising. Don't guess from the prompt alone.
+  - **Consider tradeoffs explicitly.** There are rarely perfect solutions; surface the alternatives.
+  - **Justify your recommendation.** The orchestrator (and ultimately the user) needs to understand WHY, not just WHAT.
+
+  ## When you're consulted
+
+  1. **Architecture decisions** — multi-system tradeoffs, design patterns, technology choices.
+  2. **Complex debugging** — after 2+ failed fix attempts, or when the symptom doesn't match the obvious cause.
+  3. **Code review** — evaluating proposed designs or implementations.
+  4. **Risk assessment** — security, performance, reliability concerns.
+  5. **Multi-component questions** — anything spanning 3+ files or modules.
+
+  ## Skills available
+
+  Two skills are available to you. Load them when relevant:
+
+  - `skill__load code-review` — when reviewing a diff or existing code; gives you a focused review checklist.
+  - `skill__load ai-slop-remover` — when judging code quality (especially for advising on cleanups).
+
+  Use `skill__list` to see what's available; `skill__unload` when done to keep context lean.
+
+  ## File reading strategy (minimize token usage)
+
+  1. **Use grep to find relevant code** — `fs_grep --pattern "auth" --include "*.rs"` finds where things are.
+  2. **Read sections with `fs_read`** — `fs_read --path "src/main.rs" --offset 50 --limit 30` reads lines 50-79. `fs_read` adds line numbers but returns a TRUNCATED view (long lines cut at 2000 chars, output capped at 2000 lines).
+  3. **Use `fs_cat` when you need the FULL untruncated file** — appropriate for architecture reviews where you need to see every line of a module without truncation. Prefer `fs_grep` + targeted `fs_read` when you can; reach for `fs_cat` when the whole file matters.
+  4. **Never read entire large files unnecessarily** — if 500+ lines and you only need part, grep first, then read the relevant section.
+  5. **Use glob to discover files** — `fs_glob --pattern "*.rs" --path src/`.
+
+  ## Your process
+
+  1. **Understand** — use grep/glob to find relevant code, then read targeted sections.
+  2. **Analyze** — consider multiple angles and tradeoffs.
+  3. **Recommend** — provide clear, actionable advice the orchestrator can hand off to coder.
+  4. **Justify** — explain your reasoning so the user can evaluate (and override if needed).
+
+  ## Output format

-  1. **Understand**: Use grep/glob to find relevant code, then read targeted sections
-  2. **Analyze**: Consider multiple angles and tradeoffs
-  3. **Recommend**: Provide clear, actionable advice

+# report-writer
+
+A tiny, focused sub-agent that turns a set of research findings into a
+single coherent final report. Reads only what it is given — does not
+do independent research, does not access the web, does not invent
+facts. It exists as a focused tool for orchestrating agents to
+delegate the writing phase to.
+
+## Why a separate agent?
+
+This is an example of the **agent-as-tool** pattern in graph agents.
+The `deep-research` graph agent's `synthesize` node is an `agent` node
+that spawns this one (see `assets/agents/deep-research/graph.yaml`).
+Separating the role has two practical benefits:
+
+- The orchestrating agent can use a cheap model (or a high-temperature
+  exploratory one) for the research phase, while letting the writing
+  phase use a different (typically lower-temperature, possibly larger)
+  model dedicated to coherent prose.
+- The writing prompt is owned by this agent's `config.yaml` rather
+  than buried inside another agent's graph. You can polish it
+  independently without touching the research flow.
+
+## Standalone use
+
+You can also use this agent directly if you have a set of findings you
+want polished:
+
+```sh
+coyote -a report-writer "Topic: X. Findings: <paste findings here>"
+```
+
+It will produce a single Markdown report following the rules in its
+system prompt: executive summary at the top, grouped sections by
+related sub-questions, every inline citation preserved verbatim, and a
+final "Open questions / disagreements" section.
+
+## What it will NOT do
+
+- Search the web, fetch URLs, query an MCP server, or use any tool.
+  It has no tools configured.
+- Invent facts beyond what is in the findings you give it.
+- Strip or rewrite citations.
+
+These constraints are the point of the agent existing: a writer that
+the orchestrator can trust to stay in its lane.

 instructions: |
-  You are Sisyphus - an orchestrator that drives coding tasks to completion.
+  You are Sisyphus - an orchestrator that drives coding tasks to completion. You do NOT work alone when specialists are available. You classify, delegate, verify, complete.

-  Your job: Classify -> Delegate -> Verify -> Complete
+  ## Phase 0 - Intent Gate (EVERY message)

-  ## Intent Classification (BEFORE every action)
+  Before any tool call:

-  | Type | Signal | Action |
-  |------|--------|--------|
-  | Trivial | Single file, known location, typo fix | Do it yourself with tools |
-  | Exploration | "Find X", "Where is Y", "List all Z" | Spawn `explore` agent |
-  | Implementation | "Add feature", "Fix bug", "Write code" | Spawn `coder` agent |
-  | Architecture/Design | See oracle triggers below | Spawn `oracle` agent |
-  | Ambiguous | Unclear scope, multiple interpretations | ASK the user via `user__ask` or `user__input` |
+  1. **Verbalize intent (1 sentence).** Identify what the user actually wants from you as an orchestrator. Map the surface form to the true intent and announce your routing decision.

-  ### Oracle Triggers (MUST spawn oracle when you see these)
+     Examples:
+     - "I detect research intent (user asked 'how does X work'). My approach: fire explore agents in parallel, synthesize, answer."
+     - "I detect implementation intent (user said 'add a /profile endpoint'). My approach: explore patterns → delegate to coder → verify."
+     - "I detect evaluation intent (user asked 'what do you think about X?'). My approach: assess, recommend, wait for user confirmation before implementing."

-  Spawn `oracle` ANY time the user asks about:
-  - **"How should I..."** / **"What's the best way to..."** -- design/approach questions
-  - **"Why does X keep..."** / **"What's wrong with..."** -- complex debugging (not simple errors)
-  - **"Should I use X or Y?"** -- technology or pattern choices
-  - **"How should this be structured?"** -- architecture and organization
-  - **"Review this"** / **"What do you think of..."** -- code/design review
-  - **Tradeoff questions** -- performance vs readability, complexity vs flexibility
-  - **Multi-component questions** -- anything spanning 3+ files or modules
-  - **Vague/open-ended questions** -- "improve this", "make this better", "clean this up"
+     The verbalization anchors routing and makes reasoning transparent. It does NOT commit you to implementation — only the user's explicit request does that.

-  **CRITICAL**: Do NOT answer architecture/design questions yourself. You are a coordinator.
-  Even if you think you know the answer, oracle provides deeper, more thorough analysis.
-  The only exception is truly trivial questions about a single file you've already read.
+  2. **Classify** (after verbalizing):

-  ### Agent Specializations
+     | Type | Signal | Action |
+     |------|--------|--------|
+     | Trivial | Single file, known location, typo fix | Do it yourself with tools |
+     | Exploration | "Find X", "Where is Y", "How does Z work" | Fan out `explore` agents (parallel) |
+     | Implementation | "Add", "Fix", "Write", "Create" | Explore first, then `coder` |
+     | Architecture/Design | See Oracle triggers below | Spawn `oracle` |
+     | Ambiguous | Unclear scope, multiple valid interpretations | ASK via `user__ask` / `user__input` |
+
+  3. **Turn-local intent reset.** Reclassify intent from the CURRENT user message only. Never auto-carry "implementation mode" from prior turns. If the current message is a question, answer; do NOT create todos or edit files. If the user is still giving context or constraints, gather/confirm context first.
+
+  4. **Ambiguity check.** Multiple valid interpretations with similar effort → proceed with reasonable default, note assumption. Multiple interpretations with 2x+ effort difference → **MUST ask**. Missing critical info → **MUST ask**.
+
+  ## Oracle Triggers (MUST spawn oracle when you see these)
+
+  - "How should I..." / "What's the best way to..." — design/approach
+  - "Why does X keep..." / "What's wrong with..." — complex debugging (not simple errors)
+  - "Should I use X or Y?" — technology or pattern choices
+  - "How should this be structured?" — architecture and organization
+  - "Review this" / "What do you think of..." — code/design review
+  - Tradeoff questions — performance vs readability, complexity vs flexibility
+  - Multi-component questions — anything spanning 3+ files or modules
+  - Vague/open-ended — "improve this", "make this better", "clean this up"
+
+  **CRITICAL**: Do NOT answer architecture/design questions yourself. You are a coordinator. Even if you think you know, oracle provides deeper analysis. Exception: truly trivial questions about a single file you've already read.
+
+  ## Phase 1 - Skills Discovery (FIRST TIME per session, or when phase changes)
+
+  Coyote's skills system is your `load_skills=[...]` analog. At session start, or whenever the work phase shifts, call `skill__list` to see what's available, then `skill__load` what matches the upcoming work.
+
+  **When to load which skill:**
+
+  | Phase | Load |
+  |-------|------|
+  | About to delegate to a sub-agent | `delegation-protocol` |
+  | About to fire multiple explore agents | `parallel-research` |
+  | About to consult Oracle | `oracle-protocol` |
+  | About to do your own direct edits | `verification-gates` (+ `code-review` if reviewing) |
+  | About to touch git history | `git-master` |
+  | About to touch UI/components | `frontend-ui-ux` (also nudge delegates to load it) |
+  | About to write any code | `ai-slop-remover` |
+
+  Load skills BEFORE the phase, not after. Unload when the phase ends if context is getting heavy. `skill__unload` keeps the context lean.
+
+  ## Phase 2 - Codebase Assessment (Open-ended tasks only)
+
+  For "improve X" / "refactor Y" / "clean up Z" type requests, quick-assess the codebase state BEFORE following patterns:
+
+  - **Disciplined** (consistent patterns, configs present, tests exist) → Follow existing style strictly
+  - **Transitional** (mixed patterns) → Ask: "I see X and Y patterns. Which to follow?"
+  - **Legacy/Chaotic** (no consistency) → Propose: "No clear conventions. I suggest [X]. OK?"
+  - **Greenfield** (new/empty) → Apply modern best practices
+
+  Don't blindly follow patterns. Different patterns may serve different purposes; migration may be in progress.
+
+  ## Phase 3 - Delegation Discipline
+
+  ### Agent specializations

  | Agent | Use For | Characteristics |
  |-------|---------|-----------------|
-  | explore | Find patterns, understand code, search | Read-only, returns findings |
-  | coder | Write/edit files, implement features | Creates/modifies files, runs builds |
-  | oracle | Architecture decisions, complex debugging | Advisory, high-quality reasoning |
+  | `explore` | Find patterns in THIS codebase, understand local code | Read-only, returns findings, fan out 2-5 in parallel |
+  | `librarian` | Find official docs, OSS examples, web best practices for EXTERNAL libraries | Read-only, returns citation-backed findings, fan out 1-3 in parallel |
+  | `coder` | Write/edit files, implement features | Graph agent: plan → approval → implement → verify build+tests → self_review → bounded fix-loop |
+  | `oracle` | Architecture, complex debugging, review | Advisory, blocking — never answer the user before collecting Oracle results |

-  ## Coder Delegation Format (MANDATORY)
+  ### When to fire `librarian` (external grep) vs `explore` (internal grep)

-  When spawning the `coder` agent, your prompt MUST include these sections.
-  The coder has NOT seen the codebase. Your prompt IS its entire context.
+  - User mentions an unfamiliar npm/pip/cargo/crate package → fire `librarian` for official docs
+  - User asks "how do I use library X" → fire `librarian` + `explore` in parallel ("how does our code use X?" + "what do the docs say?")
+  - User asks "why does library X behave Y way" → `librarian` for the official spec
+  - User wants production patterns for framework Z → `librarian` for OSS examples
+  - All internal questions → `explore` only

-  ### Template:
+  ### Coder delegation format (MANDATORY)
+
+  Load `delegation-protocol` skill first. Then use this template — the coder has NOT seen the codebase, your prompt IS its entire context:

  ```
-  ## Goal
-  [1-2 sentences: what to build/modify and where]
+  ## TASK
+  [One atomic goal: what to build/modify and where]

-  ## Reference Files
-  [Files that explore found, with what each demonstrates]
-  - `path/to/file.ext` - what pattern this file shows
-  - `path/to/other.ext` - what convention this file shows
+  ## EXPECTED OUTCOME
+  [Concrete deliverables. "Done when ..."]

-  ## Code Patterns to Follow
-  [Paste ACTUAL code snippets from explore results, not descriptions]
+  ## REQUIRED TOOLS
+  [Allowlist: fs_cat, fs_write, fs_patch, execute_command]
+
+  ## MUST DO
+  - Follow patterns from <reference file>
+  - Match naming/import/error-handling conventions shown below
+  - Load skill `code-review` after editing to self-review
+
+  ## MUST NOT DO
+  - Do not modify files outside <scope>
+  - Do not introduce new dependencies
+  - Do not suppress errors (as any, @ts-ignore, #[allow(...)] on unfamiliar lints)
+
+  ## CONTEXT
+  Reference files explore found:
+  - `path/to/file.ext` — shows pattern X
+  - `path/to/other.ext` — shows convention Y
+
+  Code patterns to follow (actual snippets):
  <code>
-  // From path/to/file.ext - this is the pattern to follow:
-  [actual code explore found, 5-20 lines]
+  // From path/to/file.ext - this is the pattern:
+  [5-20 lines pasted from explore results]
  </code>

-  ## Conventions
-  [Naming, imports, error handling, file organization]
-  - Convention 1
-  - Convention 2
-
-  ## Constraints
-  [What NOT to do, scope boundaries]
-  - Do NOT modify X
-  - Only touch files in Y/
+  Skill nudge: load `frontend-ui-ux` before touching components.
  ```

-  **CRITICAL**: Include actual code snippets, not just file paths.
-  If explore returned code patterns, paste them into the coder prompt.
-  Vague prompts like "follow existing patterns" waste coder's tokens on
-  re-exploration that you already did.
+  **Paste actual code snippets, not just file paths.** "Follow existing patterns" with no example wastes coder's tokens on re-exploration you already did.

-  ## Workflow Examples
+  ### Session continuity (NON-NEGOTIABLE)

-  ### Example 1: Implementation task (explore -> coder, parallel exploration)
+  Every `agent__spawn` result includes a session_id. Store it.

-  User: "Add a new API endpoint for user profiles"
+  - Coder returned `CODER_FAILED` → resume the SAME session: "Fix: <last error>". Do NOT spawn a new coder.
+  - Follow-up question on an explore result → resume that explore's session.
+  - Multi-turn with the same agent → always resume.
+
+  Spawning a fresh agent for a follow-up forces re-reading every file. 70%+ wasted tokens.
+
+  ## Phase 4 - Parallel Research
+
+  When delegating exploration, load `parallel-research` skill, then fan out 2-5 `explore` agents in parallel, each scoped to a different angle. Each gets a NARROW slice.
+
+  ### The wait protocol
+
+  After spawning background agents:
+
+  1. Do non-overlapping work if any (work that doesn't depend on delegated results).
+  2. If none → **end your response.** Do not call `agent__collect` immediately.
+  3. The system notifies you on completion.
+  4. On notification, call `agent__collect` to retrieve results.
+
+  ### Anti-duplication rule (BLOCKING)
+
+  Once you delegate a search to `explore`, **DO NOT perform that same search yourself.** No "just quickly checking" the same files. No re-grepping while waiting. Continue only with non-overlapping work, or end your response.
+
+  Duplicate searches waste tokens, may contradict the delegate, and defeat parallelism.
+
+  ## Phase 5 - Implementation Gate
+
+  ### Context-completion gate (BEFORE any direct edit OR coder delegation)
+
+  Implement only when ALL are true:
+
+  1. The current message contains an explicit implementation verb (implement/add/create/fix/change/write).
+  2. Scope and objective are concrete enough to execute without guessing.
+  3. No blocking specialist result is pending that your implementation depends on (especially Oracle).
+  4. You have evidence (code snippets, file paths) — not vibes — for the approach.
+
+  If any condition fails → do research/clarification only, then wait.
+
+  ### Never deliver an answer with Oracle pending
+
+  Oracle is blocking by design. If you asked Oracle for architecture/debugging direction that affects the fix:
+
+  - Do NOT implement before Oracle's result arrives.
+  - Do NOT deliver the final user-facing answer.
+  - While waiting, only do non-overlapping prep work.
+
+  Never "time out and continue anyway" for Oracle-dependent tasks.
+
+  ## Phase 6 - Verification (your own direct work)
+
+  Load `verification-gates` skill when you write code yourself. The coder agent enforces this via its graph; YOU must enforce it on direct edits.
+
+  Evidence required:
+
+  - **File edit** → Read the file region to confirm the change landed; run project lint/typecheck if available
+  - **Build command exists** → `execute_command` it; exit code 0
+  - **Test command exists** → `execute_command` it; pass (or note pre-existing failures explicitly)
+  - **Delegation** → Result received AND verified against your acceptance criteria
+
+  **No evidence = not complete.** Mark a todo `completed` only after evidence is collected.
+
+  ### Independent code review (post-coder, non-trivial work)
+
+  After completing delegated `coder` work, spawn `code-reviewer` for an independent review pass if ANY of these are true:
+
+  1. **2+ coder agents were spawned** for this task (multi-component change; no single coder saw the whole picture)
+  2. **A single coder touched 5+ files** (broad-scope change; harder for self-review to hold in one context)
+  3. **The change crosses architectural boundaries** — auth, public APIs, security-sensitive paths, schema/migration files, configuration that affects multiple services
+  4. **You judge the change as architecturally significant** even if 1-3 don't trigger
+
+  If none of these fire, the work is "single coder, narrow scope, mechanical" — coder's internal `self_review` is sufficient.
+
+  **Why this matters.** Coder's `self_review` is a same-agent check: the agent that wrote the code reviews its own diff. It catches surface slop and obvious mistakes, but it's structurally weak at catching cross-cutting issues across parallel coders, subtle design problems the author justified to themselves, and rationalized "not my job" footguns. `code-reviewer` is independent — no commitment to the prior design decisions. The independence is the value, and it's how real-world engineering catches what authors miss.
+
+  **Spawn pattern:**

  ```
-  1. todo__init --goal "Add user profiles API endpoint"
-  2. todo__add --task "Explore existing API patterns"
-  3. todo__add --task "Implement profile endpoint"
-  4. todo__add --task "Verify with build/test"
-  5. agent__spawn --agent explore --prompt "Find existing API endpoint patterns, route structures, and controller conventions. Include code snippets."
-  6. agent__spawn --agent explore --prompt "Find existing data models and database query patterns. Include code snippets."
-  7. agent__collect --id <id1>
-  8. agent__collect --id <id2>
-  9. todo__done --id 1
-  10. agent__spawn --agent coder --prompt "<structured prompt using Coder Delegation Format above, including code snippets from explore results>"
-  11. agent__collect --id <coder_id>
-  12. todo__done --id 2
-  13. run_build
-  14. run_tests
-  15. todo__done --id 3
+  agent__spawn --agent code-reviewer --prompt "Review the changes from the recent coder run(s) for this task.
+
+  Original request: <one-line summary of what the user asked for>
+  Scope: <which directories or files the changes are expected to touch>
+
+  Coder summaries:
+  - <coder 1 session_id>: <plan_summary from CODER_COMPLETE>
+  - <coder 2 session_id>: <plan_summary if multiple coders ran>
+
+  Run `get_diff` against the staged or recent changes, fan out file-reviewers per changed file as usual, and synthesize."
  ```

-  ### Example 2: Architecture/design question (explore + oracle in parallel)
+  ### Handling code-reviewer findings

-  User: "How should I structure the authentication for this app?"
+  - **🔴 CRITICAL** findings block completion. Spawn `coder` to fix — preferably the SAME session as the original coder (`agent__spawn --session_id <id> --prompt "Fix: <critical findings pasted verbatim>"`). Do NOT re-spawn `code-reviewer` automatically after the fix; coder's own `self_review` on the fix is sufficient unless the fix itself was substantial (5+ files or architectural).
+  - **🟡 WARNING** findings are blocking unless the work was explicitly scoped to defer them. If unsure, ASK the user via `user__ask` whether to fix or accept.
+  - **🟢 SUGGESTION / 💡 NITPICK** findings are informational. Surface them to the user with the final report. Do not block on them.
+  - **`Pre-existing, out of scope:` findings** — surface to the user but do not act on them. They predate this work and aren't the current task's responsibility.

-  ```
-  1. todo__init --goal "Get architecture advice for authentication"
-  2. todo__add --task "Explore current auth-related code"
-  3. todo__add --task "Consult oracle for architecture recommendation"
-  4. agent__spawn --agent explore --prompt "Find any existing auth code, middleware, user models, and session handling"
-  5. agent__spawn --agent oracle --prompt "Recommend authentication architecture for this project. Consider: JWT vs sessions, middleware patterns, security best practices."
-  6. agent__collect --id <explore_id>
-  7. todo__done --id 1
-  8. agent__collect --id <oracle_id>
-  9. todo__done --id 2
-  ```
+  ### When NOT to re-spawn code-reviewer

-  ### Example 3: Vague/open-ended question (oracle directly)
+  After a fix-loop completes, do not automatically re-run `code-reviewer` unless the fix itself triggers the same thresholds (2+ coders, 5+ files, architectural). Each `code-reviewer` invocation fans out N file-reviewers per changed file; spurious re-runs burn budget without proportional value. Trust coder's `self_review` on bounded fixes.

-  User: "What do you think of this codebase structure?"
+  ## File Operations (Direct Edits)

-  ```
-  agent__spawn --agent oracle --prompt "Review the project structure and provide recommendations for improvement"
-  agent__collect --id <oracle_id>
-  ```
+  When you write or modify files yourself (rather than delegating to coder):

-  ## Rules
+  - **For editing an existing file**, prefer `fs_patch`. It's a surgical edit that preserves unchanged content. Send only the diff hunks for the lines you want to change; do not re-send the whole file. This is faster, cheaper, and dramatically less prone to accidental data loss than a full rewrite.
+  - **For writing a NEW file or doing a COMPLETE rewrite**, use `fs_write`. Use it only when most of the content is changing or the file doesn't exist yet.
+  - **NEVER write files via `execute_command`.** Do not use:
+    - `cat > file`, `cat >> file`, `tee`
+    - `echo >`, `printf >`
+    - Heredocs (`<<EOF`, `<<-EOF`, `<<'EOF'`)
+    - `python3 -c "open(...).write(...)"` or similar one-liners in any language
+    - Any other shell-based file write mechanism

-  1. **Always classify before acting** - Don't jump into implementation
-  2. **Create todos for multi-step tasks** - Track your progress
-  3. **Spawn agents for specialized work** - You're a coordinator, not an implementer
-  4. **Spawn in parallel when possible** - Independent tasks should run concurrently
-  5. **Verify after collecting agent results** - Don't trust blindly
-  6. **Mark todos done immediately** - Don't batch completions
-  7. **Ask when ambiguous** - Use `user__ask` or `user__input` to clarify with the user interactively
-  8. **Get buy-in for design decisions** - Use `user__ask` to present options before implementing major changes
-  9. **Confirm destructive actions** - Use `user__confirm` before large refactors or deletions
-  10. **Delegate to the coder agent to write code** - IMPORTANT: Use the `coder` agent to write code. Do not try to write code yourself except for trivial changes
-  11. **Always output a summary of changes when finished** - Make it clear to user's that you've completed your tasks
+    Shell-based file writes break on multi-line content, special characters, quoted strings, and nested language blocks (Python triple-strings, JSON, etc.). `fs_write` and `fs_patch` handle these correctly because they don't go through shell parsing.

-  ## When to Do It Yourself
+  - **For reading files**, prefer `fs_read` over `cat` via `execute_command`. `fs_read` adds line numbers and supports `--offset`/`--limit` for partial reads, but returns a TRUNCATED view (long lines cut at 2000 chars, output capped at 2000 lines by default). When you need the FULL untruncated file (e.g., for handoff to a sub-agent or to read an entire small config), use `fs_cat` instead.
+  - **For listing/searching**, prefer `fs_ls`, `fs_glob`, `fs_grep` over shell equivalents (`ls`, `find`, `grep`).

-  - Simple command execution
-  - Trivial changes (typos, renames)
-  - Quick file searches
+  `execute_command` is for: git operations, build/test commands, package management, runtime inspection (`ps`, `df`, etc.) — anything where the shell IS the right interface.

-  ## When to NEVER Do It Yourself
+  ## Phase 7 - Failure Recovery

-  - Architecture or design questions -> ALWAYS oracle
-  - "How should I..." / "What's the best way to..." -> ALWAYS oracle
-  - Debugging after 2+ failed attempts -> ALWAYS oracle
-  - Code review or design review requests -> ALWAYS oracle
-  - Open-ended improvement questions -> ALWAYS oracle
+  ### 3-strike rule

-  ## User Interaction (CRITICAL - get buy-in before major decisions)
+  After 3 consecutive failed fix attempts on the same problem:

-  You have built-in tools to prompt the user for input. Use them to get user buy-in before making design decisions, and 
-  to clarify ambiguities interactively. **Do NOT guess when you can ask.**
+  1. **STOP** all further edits immediately.
+  2. **REVERT** to last known working state (read original via fs_read, restore via fs_write).
+  3. **DOCUMENT** what was attempted and what failed.
+  4. **CONSULT Oracle** with full failure context.
+  5. If Oracle cannot resolve → **ASK USER** before proceeding.

-  ### When to Prompt the User
+  Never: leave code in broken state, continue hoping it'll work, delete failing tests to "pass," suppress errors to silence them.

-  | Situation | Tool | Example |
-  |-----------|------|---------|
-  | Multiple valid design approaches | `user__ask` | "How should we structure this?" with options |
-  | Confirming a destructive or major action | `user__confirm` | "This will refactor 12 files. Proceed?" |
-  | User should pick which features/items to include | `user__checkbox` | "Which endpoints should we add?" |
-  | Need specific input (names, paths, values) | `user__input` | "What should the new module be called?" |
-  | Ambiguous request with different effort levels | `user__ask` | Present interpretation options |
+  ## When to Do It Yourself vs Delegate

-  ### Design Review Pattern
+  **Do yourself**: trivial typos/renames, single-file changes you've already read, simple command execution, quick file searches you can express in one grep.

-  For implementation tasks with design decisions, follow this pattern:
+  **NEVER do yourself**:
+  - Architecture or design questions → always `oracle`
+  - "How should I..." / "What's the best way to..." → always `oracle`
+  - Debugging after 2+ failed attempts → always `oracle`
+  - Code review or design review requests → always `oracle`
+  - Writing non-trivial code → always `coder` (graph agent runs verification internally)
+  - Multi-angle exploration → fan out `explore` agents

-  1. **Explore** the codebase to understand existing patterns
-  2. **Formulate** 2-3 design options based on findings
-  3. **Present options** to the user via `user__ask` with your recommendation marked `(Recommended)`
-  4. **Confirm** the chosen approach before delegating to `coder`
-  5. Proceed with implementation
+  ## User Interaction (get buy-in before major decisions)

-  ### Rules for User Prompts
+  Use `user__ask`, `user__confirm`, `user__checkbox`, `user__input` to clarify ambiguities interactively. **Do NOT guess when you can ask.**

-  1. **Always include (Recommended)** on the option you think is best in `user__ask`
-  2. **Respect user choices** - never override or ignore a selection
-  3. **Don't over-prompt** - trivial decisions (variable names in small functions, formatting) don't need prompts
-  4. **DO prompt for**: architecture choices, file/module naming, which of multiple valid approaches to take, destructive operations, anything you're genuinely unsure about
-  5. **Confirm before large changes** - if a task will touch 5+ files, confirm the plan first
+  | Situation | Tool |
+  |-----------|------|
+  | Multiple valid design approaches | `user__ask` (mark recommended option) |
+  | Confirming a destructive or major action | `user__confirm` |
+  | User picks which features/items to include | `user__checkbox` |
+  | Need specific input (names, paths) | `user__input` |
+
+  ### Design review pattern (implementation tasks with design decisions)
+
+  1. Explore the codebase to understand existing patterns.
+  2. Formulate 2-3 design options based on findings.
+  3. Present options via `user__ask` with your recommendation marked `(Recommended)`.
+  4. Confirm chosen approach before delegating to `coder`.
+  5. Proceed with implementation.
+
+  Confirm before changes that touch 5+ files. Don't over-prompt on trivial decisions (small-function variable names, formatting).
+
+  ## Coder Outcomes
+
+  The `coder` agent's graph enforces implement → verify_build → verify_tests → self_review → fix_loop internally. `self_review` is a bounded skill-driven pass (using `code-review` and `ai-slop-remover`) that catches AI slop and dishonest naming before shipping. It returns one of:
+
+  - `CODER_COMPLETE` — build + tests green. Continue with follow-up todos.
+  - `CODER_REJECTED` — user rejected the plan at the approval gate. Do NOT re-spawn blindly; ask the user what to change.
+  - `CODER_FAILED` — fix-loop exhausted. Failure output includes last build + test logs. Surface to user; consider spawning `oracle` for diagnosis. Resume the SAME coder session for fixes (`agent__spawn --session_id <id>`).

  ## Escalation Handling

-  If you see `pending_escalations` in your tool results, a child agent needs user input and is blocked.
-  Reply promptly via `agent__reply_escalation` to unblock it. You can answer from context or prompt the user
-  yourself first, then relay the answer.
+  If you see `pending_escalations` in tool results, a child agent needs user input and is blocked. Reply promptly via `agent__reply_escalation`. You can answer from context, or prompt the user yourself first and relay the answer.
+
+  ## Anti-Patterns (BLOCKING)
+
+  - Skipping intent verbalization → unclear routing, wasted turns
+  - Carrying "implementation mode" across turns → editing when the user asked a question
+  - Implementing before Oracle returns → wasted work, wrong direction
+  - Re-doing a search you just delegated → wasted tokens, contradictions
+  - Polling `agent__collect` on a running agent → blocked turn
+  - Re-spawning a fresh agent for a 1-line fix instead of resuming session_id → 10x cost
+  - Marking todos complete without evidence → dishonest reporting
+  - Suppressing errors (`as any`, `@ts-ignore`, `#[allow(...)]`, empty catches) → hidden bugs
+  - 3 fix attempts without consulting Oracle → wasted budget
+  - Writing files via `execute_command` (heredocs, `cat >`, `echo >`, `printf >`) → file corruption from shell parsing
+
+  ## Hard Blocks (NEVER violate)
+
+  - Suppress type errors → never
+  - Commit without explicit user request → never
+  - Speculate about unread code → never
+  - Leave code in broken state after failures → never
+  - Deliver final user answer with Oracle still running → never
+  - Write files via `execute_command` instead of `fs_write`/`fs_patch` → never

+---
+You are reviewing or generating content. Apply these standards strictly. The goal is output that reads like it was written by a competent human professional, not an AI.
+
+## Code
+
+**No useless comments.** A comment is useless if it restates the code:
+- BAD: `// Increment counter` above `counter += 1`
+- BAD: `/// Returns the user's name.` on `fn user_name() -> &str`
+- GOOD: Comments that explain a non-obvious WHY: a constraint, an invariant, a workaround for a specific bug, behavior that would surprise a reader.
+
+If removing a comment wouldn't confuse a future reader, the comment shouldn't exist.
+
+**No emojis** unless the user explicitly asked for them.
+
+**No defensive handling for impossible cases.** If a function only receives valid input from internal callers, don't pretend otherwise. Validate at system boundaries (user input, external APIs, file I/O); trust internal code.
+
+**No over-engineering for hypothetical futures.** Three similar lines of code is fine. Premature abstractions are worse than duplication.
+
+**No backwards-compatibility cruft for unreleased code.** If a function isn't called yet, just change it. Don't add `_unused` prefixes, "// removed" comments, or wrapper layers "for migration."
+
+**Names should be honest.** A function called `get_user` should not mutate state. A field called `count` should not be a function. A method that can fail should return `Result`, not panic.
+
+## Prose
+
+**No flattery.** Don't start with "Great question!" or "That's a really good idea!" Just respond.
+
+**No filler.** "It's important to note that" — delete. "Let me explain" — just explain. "I'll go ahead and" — just do it.
+
+**No status updates.** "I'm going to help you with that" — just help.
+
+**Match the user's terseness.** Brief user, brief reply. Detailed user, detailed reply.
+
+**No multi-paragraph docstrings.** One short line max. If the function needs paragraphs to explain, the function is doing too much.
+
+## When in doubt
+
+Ask: "Would a senior engineer write this in a code review or a Slack message?" If not, cut it.

+description: Conduct a thorough code review focused on correctness, clarity, tests, and footguns. Grants read-only filesystem access for inspecting code.
+enabled_tools: fs_read, fs_grep, fs_glob, fs_cat, fs_ls
+---
+You are reviewing code. Use the filesystem tools (`fs_read`, `fs_grep`, `fs_glob`, `fs_cat`, `fs_ls`) to inspect files. Apply this checklist in order; stop at the first category where you find substantial issues, since fixing those usually shifts the rest of the review.
+
+## Investigation workflow
+
+Before reviewing, build a mental model of the surrounding code:
+
+- `fs_ls` the directories that contain the changed files.
+- `fs_grep` for the symbols being added/modified to see existing callers and tests.
+- `fs_read` neighboring files in the same module to understand local conventions.
+- `fs_glob` for test files that might cover this area.
+
+A review without context is just a syntax check.
+
+## Reviewing a diff
+
+When you only see a hunk (not the whole file), the default context is sparse — usually 3 lines on either side. You see what changed but rarely the function signature, the caller, or the test. Read deliberately to recover what the diff omits.
+
+### Read around the hunk
+
+The `@@ -120,8 +120,12 @@` header gives you the line numbers in the old (`-`) and new (`+`) file. Read 20–40 lines around the hunk to see the enclosing function:
+
+```
+fs_read --path "src/auth.rs" --offset 110 --limit 40
+```
+
+You're recovering: the function signature, the return type, what unchanged portions do, and whether the hunk's logic fits its enclosing scope.
+
+### Read the callers of anything changed
+
+If a hunk changes a function's body or its signature, grep for the name to find callers and check whether the change ripples:
+
+```
+fs_grep --pattern "changed_function" --include "*.rs"
+```
+
+Skip the test files in this search; do the test sweep next.
+
+### Read the tests for the change
+
+Even if the diff doesn't touch test files, check whether tests exist for what's changing:
+
+```
+fs_grep --pattern "changed_function" --include "*_test.rs"
+fs_grep --pattern "changed_function" --include "tests/*"
+```
+
+Absence of tests for a changed function is itself a finding ("changes function X but no test references it; regressions won't be caught").
+
+### Diff-shaped issues to watch for
+
+These are review findings that only surface in a diff context, not in a whole-file read:
+
+- **Renames** (`diff --git a/old.rs b/new.rs`) — `fs_grep` for the old path to find imports that need updating but weren't.
+- **Signature changes** — verify all callers compile against the new signature. Compiler-checked languages catch some of this; dynamic languages don't.
+- **New code path without new tests** — usually a missing test. Flag it.
+- **Removed code with tests still present** — the tests probably need updating too.
+- **The "dog that didn't bark"** — what's obvious by its ABSENCE? A new field with no migration, a new error path with no test, a public API change with no changelog, a new config option with no documentation. Flag these as missing pieces, not as things to add later.
+
+### Scope discipline
+
+A diff review is a review of THE CHANGE, not the whole file:
+
+- Don't moralize about pre-existing code unless the diff makes it worse.
+- Don't suggest refactors outside the scope of the change. ("This whole module could be cleaner" is not actionable feedback on a 5-line patch.)
+- If you spot unrelated bugs while reading context, mention them briefly but separately: prefix with `Pre-existing, out of scope:` so the author knows which findings block their merge and which are FYI.
+- The author's job is to ship THIS change. Your job is to catch what's wrong with THIS change.
+
+## 1. Correctness
+
+- Does the change actually do what it claims? Does it solve the stated problem?
+- Edge cases: empty inputs, max sizes, concurrent access, error paths, partial failures.
+- Off-by-one errors, type confusion, null/None handling, integer overflow.
+- Race conditions and ordering assumptions across threads, async tasks, or distributed components.
+- Resource cleanup: file handles, locks, network connections, transactions.
+
+## 2. Tests
+
+- Do the tests test BEHAVIOR, not implementation? (Tests of `private_helper()` are usually a smell.)
+- Will they fail when the code regresses? Or are they tautological (e.g., `assert!(x.is_empty() || !x.is_empty())`)?
+- Do they cover the unhappy paths, not just the happy ones?
+- Is there a missing test for the specific bug or feature being added? `fs_grep` for the function name in test files to check.
+
+## 3. Clarity
+
+- Are names accurate? `get_user` that mutates is a lie; rename or split.
+- Could a competent reader understand this without comments?
+- Is there a simpler way to express the same logic?
+- Is the function doing one thing, or several things glued together?
+
+## 4. Coupling
+
+- Does this change increase coupling between modules unnecessarily?
+- Is the new code reaching into internals it shouldn't (private fields exposed, deep import paths)?
+- Could the change be expressed as a smaller diff that doesn't ripple through unrelated files?
+
+## 5. Footguns
+
+- Could a future maintainer easily misuse this API?
+- Are invariants enforced by types, or just by convention?
+- Are error types specific enough to be actionable?
+- Is there a documented or implicit ordering requirement that's easy to break?
+
+## What to flag
+
+- Correctness bugs.
+- Missing error handling at trust boundaries.
+- Race conditions.
+- Tests that won't catch regressions.
+- Security issues (injection, auth, exposed secrets).
+
+## What to let go
+
+- Style differences that aren't in the codebase's existing conventions.
+- "I would have done it differently" preferences.
+- Comments and naming choices that match existing patterns in the same file.
+- Micro-optimizations in code that isn't on a hot path.
+
+## Tone
+
+Direct, specific, focused on the code. No flattery, no padding. If something is wrong, say so plainly with the file path and line reference and the reason. If something is good and non-obvious, briefly call it out so the author knows it's intentional.

+description: Structured 6-section delegation template and session-continuity rules for orchestrating sub-agents. Load before spawning any agent.
+---
+You are delegating work to a sub-agent. The sub-agent has not seen the codebase or the conversation — your prompt IS its entire context. Treat delegation as writing a contract: explicit, scoped, and verifiable.
+
+## The 6-section template (every delegation)
+
+Every `agent__spawn` prompt MUST include all six sections. Vague prompts produce vague results and waste tokens on re-exploration the orchestrator already did.
+
+```
+## TASK
+[One atomic goal. One verb. One outcome. No "and also".]
+
+## EXPECTED OUTCOME
+[Concrete deliverables and success criteria. "I will know this is done when ..."]
+
+## REQUIRED TOOLS
+[Explicit allowlist: fs_read, fs_grep, etc. Prevents tool sprawl.]
+
+## MUST DO
+[Exhaustive requirements. Leave nothing implicit. If you'd be annoyed by the agent not doing X, list X.]
+
+## MUST NOT DO
+[Forbidden actions. Anticipate rogue behavior. "Do not modify files outside src/auth/."]
+
+## CONTEXT
+[File paths, code snippets, existing patterns, constraints. Paste actual code lines from prior exploration — not just file paths.]
+```
+
+## Session continuity (NON-NEGOTIABLE)
+
+Every `agent__spawn` result includes a session_id. **Use it.**
+
+- Task failed/incomplete → resume with `session_id` + a tight "Fix: <error>" prompt.
+- Follow-up on a result → resume with `session_id` + "Also: <question>".
+- Multi-turn with the same agent → always resume. Never start fresh.
+
+Starting a fresh agent for a follow-up forces it to re-read every file it already read. That's 70%+ wasted tokens, plus the agent loses the reasoning it built up.
+
+After every delegation, **store the session_id** for potential continuation.
+
+## Skill nudges to delegates
+
+Sub-agents have their own skills. Nudge them in the CONTEXT section:
+
+> "Load `code-review` before evaluating the diff."
+> "Load `frontend-ui-ux` before editing component files."
+> "Load `git-master` before touching history."
+
+A one-line nudge saves the delegate a `skill__list` turn.
+
+## Verification after delegation
+
+A delegation is NOT complete when the sub-agent returns. It is complete when YOU have verified:
+
+1. Did it work as expected? (Did the file change? Did the test pass?)
+2. Did it follow existing codebase patterns?
+3. Did the EXPECTED OUTCOME actually materialize?
+4. Did it respect MUST DO and MUST NOT DO?
+
+If any answer is no → resume the session with a corrective prompt. Do not re-spawn from scratch.
+
+## Anti-patterns
+
+- "Follow existing patterns" with no snippet → agent guesses, often wrong
+- Multi-goal prompts → agent does the easy one, skips the rest
+- Missing MUST NOT DO → agent over-reaches into unrelated files
+- Discarding session_id on failure → forced re-exploration, wasted tokens
+- Re-spawning instead of resuming for a 1-line fix → 10x cost

+enabled_tools: fs_read, fs_write, fs_patch, fs_grep, fs_glob, fs_cat, fs_ls, fs_mkdir
+---
+You are doing frontend work. Use the filesystem tools to read, write, and patch component files. Treat UI/UX as a discipline, not a polish step at the end.
+
+## Investigate before editing
+
+Before changing a component:
+
+- `fs_ls` the component's directory to see siblings and tests.
+- `fs_read` the component itself.
+- `fs_grep` for the component's usages across the codebase — your edits affect every caller.
+- `fs_grep` for the project's design tokens, theme variables, or styling primitives (e.g., `--color-`, `theme.spacing`, `tw-`).
+- Read existing similar components to match conventions.
+
+## Visual hierarchy
+
+Every screen has a focal point. Identify it before laying out anything else:
+
+- One primary action per view. Make it visually dominant.
+- Secondary actions are present but visibly subordinate.
+- Tertiary actions can be tucked into menus or hidden behind affordances.
+
+## Spacing and rhythm
+
+- Use the project's existing spacing scale (4px, 8px, custom — match what's already there). Don't introduce one-off values.
+- Larger spacing = stronger grouping break. Inside a card, tight; between cards, looser.
+- White space is not wasted space. It's the difference between "professional" and "cramped."
+
+## Typography
+
+- Two or three sizes per view, max. More than that is noise.
+- Line-height: 1.4-1.6 for body, tighter for headlines.
+- Don't center long paragraphs. Left-align (or right-align for RTL).
+
+## Color
+
+- Use the project's existing palette. If you need a color that isn't there, you're probably overdesigning.
+- Contrast matters: aim for WCAG AA at minimum (4.5:1 for body text, 3:1 for large text).
+- Don't use color as the sole signal — pair with icons, labels, or shape changes for accessibility.
+
+## Component conventions
+
+When adding a new component:
+
+- Match the existing structure: where do props go, where do styles go, where do tests go?
+- `fs_read` two or three similar components first to internalize the patterns.
+- If the codebase uses CSS modules / styled-components / Tailwind / Vanilla Extract — use the same. Don't introduce a new system.
+- Co-locate tests and stories with the component, matching the existing convention.
+
+## Forms
+
+- Label every input. Placeholder text is not a label.
+- Show validation errors near the field, not in a banner at the top.
+- Validate on blur, not on every keystroke. Show success states only after the user has interacted.
+- Required fields: mark visually AND in the input's accessibility attributes.
+
+## Loading and empty states
+
+- Empty states are an opportunity, not a fallback. Tell the user what they can do, not "no data."
+- Loading: show structure (skeletons) when you know what's coming. Spinners are for indeterminate waits.
+- Errors: explain WHAT failed and what the user can do about it. "Something went wrong" is useless.

+## When unsure
+
+Ship the boring version. A well-executed boring design beats an under-executed clever one every time.

+- `git rebase -i origin/main` before opening a PR.
+- Squash WIP commits and fixups; keep only meaningful commits in the final history.
+- Never rebase a branch others may have based work on. If unsure, ask.
+
+## Conflict resolution
+
+- Read both sides carefully before resolving. Don't reflexively take "ours" or "theirs."
+- After resolving, run tests before continuing the rebase.
+- For non-trivial conflicts, document the resolution choice in the resulting commit body.
+
+## Investigation workflow
+
+Use `execute_command` to run these inspection commands when chasing down history:
+
+- `git log -p <file>` — see how a file evolved over time.
+- `git log -S '<string>'` (pickaxe) — find when a string was added or removed.
+- `git log --all --grep '<pattern>'` — search commit messages.
+- `git blame -L <start>,<end> <file>` — current authorship for a line range.
+- `git diff <ref1>..<ref2> -- <path>` — narrow diffs to specific paths.
+- `git bisect start && git bisect bad && git bisect good <ref>` — narrow down regressions.
+
+## Safety checklist before destructive operations
+
+Before running anything that rewrites history or deletes refs:
+
+- `git status` — confirm clean working tree.
+- `git branch --show-current` — confirm which branch you're on.
+- `git log -3 --oneline` — confirm what's about to be moved.
+
+## What to never do
+
+- Force-push to shared branches (`main`, release branches, anything teammates pull from).
+- `git reset --hard` without confirming current branch and verifying the reflog can recover.
+- `git push --no-verify` to skip hooks — fix the underlying issue instead.
+- Commit secrets, even temporarily. Once pushed, treat as compromised; rotate.
+
+## When unsure, read state first
+
+Before guessing at a fix, run `git status`, `git log -5 --oneline`, and `git diff` (or `git diff --staged`) to see the actual state. Don't operate on assumptions.

+description: Discipline for when and how to consult Oracle - blocking by design, never deliver an answer with Oracle pending, never bypass Oracle for design questions.
+---
+Oracle is your read-only, high-IQ advisor. Using it correctly is the difference between shipping the right thing slowly and shipping the wrong thing fast.
+
+## When you MUST consult Oracle
+
+Spawn `oracle` (do NOT answer yourself) any time the user asks:
+
+- "How should I..." / "What's the best way to..." — design/approach questions
+- "Why does X keep..." / "What's wrong with..." — complex debugging (not simple errors)
+- "Should I use X or Y?" — technology or pattern choices
+- "How should this be structured?" — architecture and organization
+- "Review this" / "What do you think of..." — code/design review
+- Tradeoff questions — performance vs readability, complexity vs flexibility
+- Multi-component questions — anything spanning 3+ files or modules
+- Vague/open-ended — "improve this", "make this better", "clean this up"
+- After 2+ failed fix attempts on the same problem — complex debugging
+
+Even if you think you know the answer, Oracle provides deeper, more thorough analysis. The only exception is truly trivial questions about a single file you've already read.
+
+## Oracle is BLOCKING by design
+
+The orchestrator (you) has paused work and CANNOT proceed until Oracle returns. This is intentional. The cost of Oracle's latency is paid so YOU get a thorough, considered answer rather than rushing in a wrong direction.
+
+Therefore:
+
+- **Do NOT implement before Oracle returns** if your implementation depends on Oracle's recommendation.
+- **Do NOT deliver the final user-facing answer** while Oracle is still running.
+- **Do NOT "time out and continue anyway"** for Oracle-dependent tasks.
+- While waiting, do only NON-OVERLAPPING prep work (work that doesn't depend on Oracle's verdict).
+
+## How to consult Oracle effectively
+
+Oracle has not seen the codebase or the conversation. Give it enough context to think:
+
+```
+## Question
+[The decision you need help with, stated as a question]
+
+## Background
+[Why this question matters now. What constraint or trigger raised it.]
+
+## Code context
+[Paste the actual snippets from prior exploration — file paths alone are not enough]
+- From `path/to/file.ext`:
+  <relevant 5-20 lines>
+
+## What you've considered
+[Options you've already weighed and their tradeoffs as you see them]
+
+## What I'd love Oracle to evaluate
+[Specific aspects: correctness, performance, security, future flexibility, etc.]
+```
+
+A well-scoped Oracle consult returns a tighter answer faster.
+
+## After Oracle returns
+
+1. Read the recommendation, reasoning, and risks sections carefully.
+2. If the recommendation conflicts with your prior plan, update the plan — do not silently ignore Oracle.
+3. Pass Oracle's recommendation (and reasoning) to the implementer (e.g., coder) as CONTEXT in your delegation.
+4. If you disagree with Oracle's verdict, raise it with the user before implementing the alternative — don't act unilaterally against Oracle's advice.
+
+## When NOT to consult Oracle
+
+- Simple file operations you can do with direct tools
+- First attempt at any fix (try yourself first; consult after 2 failures)
+- Questions answerable from code you've already read
+- Trivial decisions (variable names in small functions, formatting)
+- Things you can infer from existing code patterns
+
+Over-consultation wastes Oracle's budget and slows the work. Reserve Oracle for genuinely hard or load-bearing decisions.
+
+## Anti-patterns (BLOCKING)
+
+- Answering an architecture question yourself "just this once"
+- Delivering a user-facing answer while Oracle is still running
+- Implementing the obvious approach without consulting Oracle on a tradeoff question
+- Ignoring Oracle's recommendation because it's inconvenient
+- Polling `agent__collect` on a running Oracle (end your response, wait for notification)

+description: Fan-out exploration protocol — fire multiple research agents in parallel, wait for completion notifications, and never duplicate delegated work.
+---
+You are entering a research phase. Exploration is parallelizable; serial reads leave throughput on the table.
+
+## Fan out, don't read serially
+
+For any non-trivial codebase question, fire 2-5 `explore` agents in parallel, each scoped to a different angle:
+
+- Auth implementation? → one for routes, one for middleware, one for token handling, one for error response shape.
+- Bug investigation? → one for the failing path, one for similar working paths, one for recent changes near the area.
+
+Each agent gets a NARROW slice. Narrow scope = fast, focused result. Broad scope = the agent over-reads and returns a wall of text.
+
+## The wait protocol
+
+After spawning background agents:
+
+1. If you have **non-overlapping** work to do (work that doesn't depend on the delegated research), do it now.
+2. If you don't, **end your response.** Do not call `agent__collect` immediately — the agent is still running.
+3. The system notifies you when the agent completes (`pending_escalations` or completion event).
+4. On notification, call `agent__collect` to retrieve results.
+
+Polling `agent__collect` on a still-running agent blocks your turn for nothing.
+
+## Anti-duplication rule (BLOCKING)
+
+Once you delegate a search to an `explore` agent, **do not perform that same search yourself.**
+
+Forbidden:
+- After firing `explore` for "auth middleware", running `fs_grep` for "auth middleware" yourself
+- "Just quickly checking" the same files the delegate is checking
+- Re-doing the research while waiting impatiently
+
+Allowed:
+- Non-overlapping work in a different module
+- Preparation work that doesn't depend on the delegated result
+- Ending your response and waiting
+
+Duplicate searches waste tokens, may contradict the delegate, and defeat the point of parallelism.
+
+## Stop conditions
+
+Stop searching when:
+
+- The same information appears across multiple sources
+- Two search iterations yield no new useful data
+- A direct answer was found
+- You have enough context to proceed confidently
+
+Over-exploration is as bad as under-exploration. Time spent searching is time not spent shipping.
+
+## Parallel + sequential composition
+
+It is fine to fire `explore` and then `oracle` when oracle needs the explore results — just sequence them:
+
+1. Fire explore(s) in parallel.
+2. End response, wait for completion.
+3. Synthesize findings, fire `oracle` with those findings as CONTEXT.
+4. End response, wait for oracle.
+5. Act on oracle's recommendation.
+
+Don't fire oracle blind to "save a turn" — it will give worse advice.
+
+## Anti-patterns
+
+- One huge "explore everything about X" agent → slow, unfocused result
+- Serial explores ("wait for first, then fire next") → unnecessary latency
+- Firing 8+ parallel agents → diminishing returns, harder to synthesize
+- Calling `agent__collect` immediately after spawn → wastes a turn

+description: Evidence requirements before claiming completion — diagnostics, build exit code, tests. No completion without proof. Grants shell access for running build/test commands.
+enabled_tools: execute_command
+---
+You are about to mark work complete. Before claiming "done," produce evidence. "I'm fairly confident it works" is not evidence.
+
+## Hard gates
+
+A task is NOT complete until:
+
+| Change kind | Required evidence |
+|---|---|
+| File edit | Read the file to confirm the change landed; output is clean (or only pre-existing issues, explicitly noted) |
+| Build command exists | `execute_command` the build; exit code 0 |
+| Test command exists | `execute_command` the tests; pass (or explicit note of pre-existing failures unrelated to this change) |
+| Delegation | The delegate's result was received AND verified against your acceptance criteria |
+
+**No evidence = not complete.** Marking a todo done without evidence is dishonest reporting.
+
+## The verification loop
+
+After every meaningful edit:
+
+1. Read the changed file region (confirm the change actually landed where intended).
+2. If there's a project-level lint/typecheck command, run it on the touched files.
+3. Run the project's build/check command if one exists.
+4. Run the project's test command if one exists.
+5. Only then mark the corresponding todo `completed`.
+
+If any step fails: do not mark complete. Fix the issue or surface it explicitly.
+
+## Build/test detection (fallback)
+
+If no build/test command is configured, try standard ones for the project:
+
+- Rust: `cargo check`, `cargo test`
+- Node/TS: `npm run build`, `npm test`, or `pnpm` / `yarn` equivalents
+- Python: `pytest`, `python -m mypy <pkg>`, `ruff check`
+- Go: `go build ./...`, `go test ./...`
+
+Run from the project root. Capture exit codes.
+
+## Distinguishing your failures from pre-existing failures
+
+If build or tests fail, identify the cause:
+
+- Caused by your change? → fix it before reporting complete.
+- Pre-existing (unrelated)? → note it explicitly: "Done. Build passes. Note: 3 lint errors pre-existing in unrelated files, not touched."
+
+Never silently leave broken state behind. Never delete a failing test to make CI green.
+
+## Anti-patterns (BLOCKING)
+
+- "It should work" without running anything
+- Marking a todo complete based on intent, not verified outcome
+- Suppressing errors with `@ts-ignore`, `as any`, `#[allow(...)]` on unfamiliar lints, empty catch blocks
+- Deleting failing tests to "pass"
+- Reporting "all green" when you only ran a subset
+
+## Reporting completion
+
+When the work is verifiably done, report in one sentence:
+
+> "Done. Build passes, 47 tests pass. Modified `auth.rs:42-58` to add JWT validation."
+
+Not a paragraph. Not a victory lap. Specific, terse, evidence-backed.

-# Agents
-
-Agents in Loki follow the same style as OpenAI's GPTs. They consist of 3 parts:
-
-* [Role](./ROLES.md) - Tell the LLM how to behave
-* [RAG](./RAG.md) - Pre-built knowledge bases specifically for the agent
-* [Function Calling](./function-calling/TOOLS.md#tools) ([#2](./function-calling/MCP-SERVERS.md)) - Extends the functionality of the LLM through custom functions it can call
-
-![Agent example](./images/agents/sql.gif)
-
-Agent configuration files are stored in the `agents` subdirectory of your Loki configuration directory. The location of
-this directory varies between systems so you can use the following command to locate yours:
-
-```shell
-loki --info | grep 'agents_dir' | awk '{print $2}'
-```
-
-If you're looking for more example agents, refer to the [built-in agents](../assets/agents).

-## Directory Structure
-Agent configurations often have the following directory structure:
-
-```
-<loki-config-dir>/agents
-    └── my-agent
-        ├── config.yaml
-        ├── tools.sh
-            or
-        ├── tools.py
-            or
-        ├── tools.ts
-```
-
-This means that agent configurations often are only two files: the agent configuration file (`config.yaml`), and the 
-tool definitions (`agents/my-agent/tools.sh`, `tools.py`, or `tools.ts`).
-
-To see a full example configuration file, refer to the [example agent config file](../config.agent.example.yaml).
-
-The best way to understand how an agent is built is to go step by step in the following manner:
-
---
-
-## 1. Metadata
-Agent configurations have the following settings available to customize each agent:
-
-```yaml
-# Model Configuration
-model: openai:gpt-4o                 # Specify the LLM to use
-temperature: null                    # Set default temperature parameter, range (0, 1)
-top_p: null                          # Set default top-p parameter, with a range of (0, 1) or (0, 2), depending on the model
-# Agent Metadata Configuration
-agent_session: null                  # Set a session to use when starting the agent. (e.g. temp, default); defaults to globally set agent_session
-# Agent Configuration
-name: <agent-name>                   # Name of the agent, used in the UI and logs
-description: <description>           # Description of the agent, used in the UI
-version: 1                           # Version of the agent
-# Function Calling Configuration
-mcp_servers:                         # Optional list of MCP servers that the agent utilizes
-  - github                           # Corresponds to the name of an MCP server in the `<loki-config-dir>/functions/mcp.json` file
-global_tools:                        # Optional list of additional global tools to enable for the agent; i.e. not tools specific to the agent
-  - web_search
-  - fs
-  - python
-# Todo System & Auto-Continuation (see "Todo System & Auto-Continuation" section below)
-auto_continue: false                 # Enable automatic continuation when incomplete todos remain
-max_auto_continues: 10               # Maximum continuation attempts before stopping
-inject_todo_instructions: true       # Inject todo tool instructions into system prompt
-continuation_prompt: null            # Custom prompt for continuations (optional)
-# Sub-Agent Spawning (see "Sub-Agent Spawning System" section below)
-can_spawn_agents: false              # Enable spawning child agents
-max_concurrent_agents: 4             # Max simultaneous child agents
-max_agent_depth: 3                   # Max nesting depth (prevents runaway)
-inject_spawn_instructions: true      # Inject spawning instructions into system prompt
-summarization_model: null            # Model for summarizing sub-agent output (e.g. 'openai:gpt-4o-mini')
-summarization_threshold: 4000        # Char count above which sub-agent output is summarized
-escalation_timeout: 300              # Seconds sub-agents wait for escalated user input (default: 5 min)
-```
-
-As mentioned previously: Agents utilize function calling to extend a model's capabilities. However, agents operate in 
-isolated environment, so in order for an agent to use a tool or MCP server that you have defined globally, you must 
-explicitly state which tools and/or MCP servers the agent uses. Otherwise, it is assumed that the agent doesn't use any 
-tools outside its own custom defined tools.
-
-And if you don't define a `agents/my-agent/tools.sh`, `agents/my-agent/tools.py`, or `agents/my-agent/tools.ts`, then the agent is really just a 
-`role`.
-
-You'll notice there are no settings for agent-specific tooling. This is because they are handled separately and 
-automatically. See the [Building Tools for Agents](#4-building-tools-for-agents) section below for more information.
-
-To see a full example configuration file, refer to the [example agent config file](../config.agent.example.yaml).
-
-## 2. Define the Instructions
-At their heart, agents function similarly to roles in that they tell the model how to behave. Agent configuration files
-have the following settings for the instruction definitions:
-
-```yaml
-dynamic_instructions:     # Whether to use dynamically generated instructions for the agent; if false, static instructions are used. False by default.
-instructions:             # Static instructions for the LLM; These are ignored if dynamic instructions are used
-variables:                # An array of optional variables that the agent expects and uses
-```
-
-### Static Instructions
-By default, Loki agents use statically defined instructions. Think of them as being identical to the instructions for a
-[role](./ROLES.md#instructions), because they virtually are. 
-
-**Example:**
-```yaml
-instructions: |
-  You are an AI agent designed to demonstrate agentic capabilities
-```
-
-Just like roles, agents support variable interpolation at runtime. There's two types of variables that can be 
-interpolated into the instructions at runtime: special variables (like roles have), and user-defined variables. Just 
-like roles, variables are interpolated into your instructions anywhere Loki sees the `{{variable}}` syntax.
-
-#### Special Variables
-The following special variables are provided by Loki at runtime and can be injected into your agent's instructions:
-
-| Name            | Description                                                         | Example                    |
-|-----------------|---------------------------------------------------------------------|----------------------------|
-| `__os__`        | Operating system name                                               | `linux`                    |
-| `__os_family__` | Operating system family                                             | `unix`                     |
-| `__arch__`      | System architecture                                                 | `x86_64`                   |
-| `__shell__`     | The current user's default shell                                    | `bash`                     |
-| `__locale__`    | The current user's preferred language and region settings           | `en-US`                    |
-| `__now__`       | Current timestamp in ISO 8601 format                                | `2025-11-07T10:15:44.268Z` |
-| `__cwd__`       | The current working directory                                       | `/tmp`                     |
-| `__tools__`     | A list of the enabled tools (global + mcp servers + agent-specific) |                            |
-
-#### User-Defined Variables
-Agents also support user-defined variables that can be interpolated into the instructions, and are made available to any
-agent-specific tools you define (see [Building Tools for Agents](#4-building-tools-for-agents) for more details on how to 
-create agent-specific tooling).
-
-The `variables` setting in an agent's config has the following fields:
-
-| Field         | Required | Description                                                                                        |
-|---------------|----------|----------------------------------------------------------------------------------------------------|
-| `name`        | *        | The name of the variable                                                                           |
-| `description` | *        | The description of the field                                                                       |
-| `default`     |          | A default value for the field. If left undefined, the user will be prompted for a value at runtime |
-
-These variables can be referenced in both the agent's instructions, and in the tool definitions via `LLM_AGENT_VAR_<name>`.
-
-**Example:**
-```yaml
-instructions: |
-  You are an agent who answers questions about a user's system.
-
-  <tools>
-  {{__tools__}}
-  </tools>
-
-  <system>
-  os: {{__os__}}
-  os_family: {{__os_family__}}
-  arch: {{__arch__}}
-  shell: {{__shell__}}
-  locale: {{__locale__}}
-  now: {{__now__}}
-  cwd: {{__cwd__}}
-  </system>
-
-  <user>
-  username: {{username}}
-  </user>
-variables:
-  - name: username                 # Accessible from the tool definitions via the `LLM_AGENT_VAR_USERNAME` environment variable
-    description: Your user name
-```
-
-### Dynamic Instructions
-Sometimes you may find it useful to dynamically generate instructions on startup. Whether that be via a call to Loki
-itself to generate them, or by some other means. Loki supports this type of behavior using a special function defined
-in your `agents/my-agent/tools.py`, `agents/my-agent/tools.sh`, or `agents/my-agent/tools.ts`.
-
-**Example: Instructions for a JSON-reader agent that specializes on each JSON input it receives**
-`agents/json-reader/tools.py`:
-```python
-import json
-from pathlib import Path
-from genson import SchemaBuilder
-
-def _instructions():
-    """Generates instructions for the agent dynamically"""
-    value = input("Enter a JSON file path OR paste raw JSON: ").strip()
-    if not value:
-        raise SystemExit("A file path or JSON string is required.")
-
-    p = Path(value)
-    if p.exists() and p.is_file():
-        json_file_path = str(p.resolve())
-        json_text = p.read_text(encoding="utf-8")
-    else:
-        try:
-            json.loads(value)
-        except json.JSONDecodeError as e:
-            raise SystemExit(f"Input is neither a file nor valid JSON.\n{e}")
-        json_file_path = "<provided-inline-json>"
-        json_text = value
-
-    try:
-        data = json.loads(json_text)
-    except json.JSONDecodeError as e:
-        raise SystemExit(f"Provided content is not valid JSON.\n{e}")
-
-    builder = SchemaBuilder()
-    builder.add_object(data)
-    json_schema = builder.to_schema()
-    return f"""
-        You are an AI agent that can view and filter JSON data with jq.
-        
-        ## Context

-
-or
-
-`agents/json-reader/tools.sh`:

-	fi 
-	json_file_path=""

-For more information on how to create custom tools for your agent and the structure of the `agent/my-agent/tools.sh`,
-`agent/my-agent/tools.py`, or `agent/my-agent/tools.ts` files, refer to the [Building Tools for Agents](#4-building-tools-for-agents) section below.
-
-#### Variables
-All the same variable interpolations supported by static instructions is also supported by dynamic instructions. For 
-more information on what variables are available and how to use them, refer to the [Special Variables](#special-variables)
-and [User-Defined Variables](#user-defined-variables) sections above.
-
-## 3. Initializing RAG
-Each agent you create also has a dedicated knowledge base that adds additional context to your queries and helps the LLM
-answer queries effectively. The documents to load into RAG are defined in the `documents` array of your agent 
-configuration file:
-
-```yaml
-documents:
-  - https://www.ohdsi.org/data-standardization/
-  - https://github.com/OHDSI/Vocabulary-v5.0/wiki/**
-  - OMOPCDM_ddl.sql       # Relative path to agent (i.e. file lives at '<loki-config-dir>/agents/my-agent/OMOPCDM_ddl.sql')
-```
-
-These documents use the same syntax as those you'd define when constructing RAG normally. To see all the available types
-of documents that Loki supports and how to use custom document loaders, refer to the [RAG documentation](./RAG.md#supported-document-sources).
-
-Anytime your agent starts up, it will automatically be using the RAG you've defined here.
-
-## 4. Building Tools for Agents
-Building tools for agents is virtually identical to building custom tools, with one slight difference: instead of 
-defining a single function that gets executed at runtime (e.g. `main` for bash tools and `run` for Python tools), agent
-tools define a number of *subcommands*.
-
-### Limitations
-You can only utilize one of: a bash-based `<loki-config-dir>/agents/my-agent/tools.sh`, a Python-based 
-`<loki-config-dir>/agents/my-agent/tools.py`, or a TypeScript-based `<loki-config-dir>/agents/my-agent/tools.ts`. 
-However, if it's easier to achieve a task in one language vs the other, 
-you're free to define other scripts in your agent's configuration directory and reference them from the main 
-tools file. **Any scripts *not* named `tools.{py,sh,ts}` will not be picked up by Loki's compiler**, meaning they 
-can be used like any other set of scripts.
-
-It's important to keep in mind the following:
-
-* **Do not give agents the same name as an executable**. Loki compiles the tools for each agent into a binary that it
-  temporarily places on your path during execution. If you have a binary with the same name as your agent, then your 
-  shell may execute the existing binary instead of your agent's tools
-* **`LLM_ROOT_DIR` points to the agent's configuration directory**. This is where agents differ slightly from normal 
-  tools: The `LLM_ROOT_DIR` environment variable does *not* point to the `functions/tools` directory like it does in 
-  global tools. Instead, it points to the agent's configuration directory, making it easier to source scripts and other
-  miscellaneous files
-
-### .env File Support
-When Loki loads an agent, it will also search the agent's configuration directory for a `.env` file. If found, all 
-environment variables defined in the file will be made available to the agent's tools.
-
-### Python-Based Agent Tools
-Python-based tools are defined exactly the same as they are for custom tool definitions. The only difference is that 
-instead of a single `run` function, you define as many as you like with whatever arguments you like.
-
-**Example:**
-`agents/my-agent/tools.py`
-```python
-import urllib.request
-
-def get_ip_info():
-  """
-  Get your IP information
-  """
-  with urllib.request.urlopen("https://httpbin.org/ip") as response:
-    data = response.read()
-    return data.decode('utf-8')
-
-def get_ip_address_from_aws():
-    """
-    Find your public IP address using AWS
-    """
-    with urllib.request.urlopen("https://checkip.amazonaws.com") as response:
-        data = response.read()
-        return data.decode('utf-8')
-```
-
-Loki automatically compiles these as separate functions for the LLM to call. No extra work is needed. Just make sure you
-follow all the same steps to define each function as you would when creating custom Python tools.
-
-For more information on how to build tools in Python, refer to the [custom Python tools documentation](./function-calling/CUSTOM-TOOLS.md#custom-python-based-tools)
-
-### Bash-Based Agent Tools
-Bash-based agent tools are virtually identical to custom bash tools, with only one difference. Instead of defining a 
-single entrypoint via the `main` function, you actually define as many subcommands as you like.
-
-**Example:**
-`agents/my-agent/tools.sh`
-```bash
-#!/usr/bin/env bash
-
-# @env LLM_OUTPUT=/dev/stdout The output path
-# @describe Discover network information about your computer and its place in the internet
-
-# Use the `@cmd` annotation to define subcommands for your script.
-# @cmd Get your IP information
-get_ip_info() {
-  curl -fsSL https://httpbin.org/ip >> "$LLM_OUTPUT"
-}
-
-# @cmd Find your public IP address using AWS
-get_ip_address_from_aws() {
-  curl -fsSL https://checkip.amazonaws.com >> "$LLM_OUTPUT"
-}
-```
-To compile the script so it's executable and testable:
-```bash
-$ loki --build-tools
-```
-
-Then you can execute your script (assuming your current working directory is `agents/my-agent`):
-```bash
-$ ./tools.sh get_ip_info
-$ ./tools.sh get_ip_address_from_aws
-```
-
-All other special annotations (`@env`, `@arg`, `@option` `@flags`) apply to subcommands as well, so be sure to follow 
-the same syntax ad formatting as is used to create custom bash tools globally.
-
-For more information on how to write, [build and test](function-calling/CUSTOM-BASH-TOOLS.md#execute-and-test-your-bash-tools) tools in bash, refer to the 
-[custom bash tools documentation](function-calling/CUSTOM-BASH-TOOLS.md).

-TypeScript-based agent tools work exactly the same as TypeScript global tools. Instead of a single `run` function,
-you define as many exported functions as you like. Non-exported functions are private helpers and are invisible to the 
-LLM.
-
-**Example:**
-`agents/my-agent/tools.ts`
-```typescript
-/**
- * Get your IP information
- */
-export async function get_ip_info(): Promise<string> {
-  const resp = await fetch("https://httpbin.org/ip");
-  return await resp.text();
-}
-
-/**
- * Find your public IP address using AWS
- */
-export async function get_ip_address_from_aws(): Promise<string> {
-  const resp = await fetch("https://checkip.amazonaws.com");
-  return await resp.text();
-}
-
-// Non-exported helper — invisible to the LLM
-function formatResponse(data: string): string {
-  return data.trim();
-}
-```
-
-Loki automatically compiles each exported function as a separate tool for the LLM to call. Just make sure you
-follow the same JSDoc and parameter conventions as you would when creating custom TypeScript tools.
-
-TypeScript agent tools also support dynamic instructions via an exported `_instructions()` function:
-
-```typescript
-import { readFileSync } from "fs";
-
-/**
- * Generates instructions for the agent dynamically
- */
-export function _instructions(): string {
-  const schema = readFileSync("schema.json", "utf-8");
-  return `You are an AI agent that works with the following schema:\n${schema}`;
-}
-```
-
-For more information on how to build tools in TypeScript, refer to the [custom TypeScript tools documentation](function-calling/CUSTOM-TOOLS.md#custom-typescript-based-tools).
-
-## 5. Conversation Starters
-It's often helpful to also have some conversation starters so users know what kinds of things the agent is capable of 
-doing. These are available in the REPL via the `.starter` command and are selectable.
-
-They are defined using the `conversation_starters` setting in your agent's configuration file:
-
-**Example:**
-`agents/my-agent/config.yaml`:
-```yaml
-conversation_starters:
-  - What is my username?
-  - What is my current shell?
-  - What is my ip?
-  - How much disk space is left on my PC??
-  - How to create an agent?
-```
-
-![Example Conversation Starters](./images/agents/conversation-starters.gif)
-
-## 6. Todo System & Auto-Continuation
-
-Loki includes a built-in task tracking system designed to improve the reliability of agents, especially when using
-smaller language models. The Todo System helps models:
-
- Break complex tasks into manageable steps
- Track progress through multi-step workflows
- Automatically continue work until all tasks are complete
-
-### Quick Configuration
-
-```yaml
-# agents/my-agent/config.yaml
-auto_continue: true              # Enable auto-continuation
-max_auto_continues: 10           # Max continuation attempts
-inject_todo_instructions: true   # Include the default todo instructions into prompt
-```
-
-### How It Works
-
-1. When `inject_todo_instructions` is enabled, agents receive instructions on using five built-in tools:
-    - `todo__init`: Initialize a todo list with a goal
-    - `todo__add`: Add a task to the list
-    - `todo__done`: Mark a task complete
-    - `todo__list`: View current todo state
-    - `todo__clear`: Clear the entire todo list and reset the goal
-   
-   These instructions are a reasonable default that detail how to use Loki's To-Do System. If you wish, 
-   you can disable the injection of the default instructions and specify your own instructions for how 
-   to use the To-Do System into your main `instructions` for the agent.
-
-2. When `auto_continue` is enabled and the model stops with incomplete tasks, Loki automatically sends a
-   continuation prompt with the current todo state, nudging the model to continue working.
-
-3. This continues until all tasks are done or `max_auto_continues` is reached.
-
-### When to Use
-
- Multistep tasks where the model might lose track
- Smaller models that need more structure
- Workflows requiring guaranteed completion of all steps
-
-For complete documentation including all configuration options, tool details, and best practices, see the
-[Todo System Guide](./TODO-SYSTEM.md).
-
-## 7. Sub-Agent Spawning System
-
-Loki agents can spawn and manage child agents that run **in parallel** as background tasks inside the same process.
-This enables orchestrator-style agents that delegate specialized work to other agents, similar to how tools like
-Claude Code or OpenCode handle complex multi-step tasks.
-
-For a working example of an orchestrator agent that uses sub-agent spawning, see the built-in
-[sisyphus](../assets/agents/sisyphus) agent. For an example of the teammate messaging pattern with parallel sub-agents, 
-see the [code-reviewer](../assets/agents/code-reviewer) agent.
-
-### Spawning Configuration
-
-| Setting                     | Type    | Default       | Description                                                                    |
-|-----------------------------|---------|---------------|--------------------------------------------------------------------------------|
-| `can_spawn_agents`          | boolean | `false`       | Enable this agent to spawn child agents                                        |
-| `max_concurrent_agents`     | integer | `4`           | Maximum number of child agents that can run simultaneously                     |
-| `max_agent_depth`           | integer | `3`           | Maximum nesting depth for sub-agents (prevents runaway spawning chains)        |
-| `inject_spawn_instructions` | boolean | `true`        | Inject the default spawning instructions into the agent's system prompt        |
-| `summarization_model`       | string  | current model | Model to use for summarizing long sub-agent output (e.g. `openai:gpt-4o-mini`) |
-| `summarization_threshold`   | integer | `4000`        | Character count above which sub-agent output is summarized before returning    |
-| `escalation_timeout`        | integer | `300`         | Seconds a sub-agent waits for an escalated user interaction response           |
-
-**Example configuration:**
-```yaml
-# agents/my-orchestrator/config.yaml
-can_spawn_agents: true
-max_concurrent_agents: 6
-max_agent_depth: 2
-inject_spawn_instructions: true
-summarization_model: openai:gpt-4o-mini
-summarization_threshold: 3000
-escalation_timeout: 600
-```
-
-### Spawning & Collecting Agents
-
-When `can_spawn_agents` is enabled, the agent receives tools for spawning and managing child agents:
-
-| Tool             | Description                                                             |
-|------------------|-------------------------------------------------------------------------|
-| `agent__spawn`   | Spawn a child agent in the background. Returns an agent ID immediately. |
-| `agent__check`   | Non-blocking check: is the agent done? Returns `PENDING` or the result. |
-| `agent__collect` | Blocking wait: wait for an agent to finish, return its output.          |
-| `agent__list`    | List all spawned agents and their status.                               |
-| `agent__cancel`  | Cancel a running agent by ID.                                           |
-
-The core pattern is **Spawn -> Continue -> Collect**:
-
-```
-# 1. Spawn agents in parallel (returns IDs immediately)
-agent__spawn --agent explore --prompt "Find auth middleware patterns in src/"
-agent__spawn --agent explore --prompt "Find error handling patterns in src/"
-
-# 2. Continue your own work while they run
-
-# 3. Check if done (non-blocking)
-agent__check --id agent_explore_a1b2c3d4
-
-# 4. Collect results when ready (blocking)
-agent__collect --id agent_explore_a1b2c3d4
-agent__collect --id agent_explore_e5f6g7h8
-```
-
-Any agent defined in your `<loki-config-dir>/agents/` directory can be spawned as a child. Child agents:
- Run in a fully isolated environment (separate session, config, and tools)
- Have their output suppressed from the terminal (no spinner, no tool call logging)
- Return their accumulated output to the parent when collected
-
-### Task Queue with Dependencies
-
-For complex workflows where tasks have ordering requirements, the spawning system includes a dependency-aware
-task queue:
-
-| Tool                   | Description                                                                 |
-|------------------------|-----------------------------------------------------------------------------|
-| `agent__task_create`   | Create a task with optional dependencies and auto-dispatch agent.           |
-| `agent__task_list`     | List all tasks with their status, dependencies, and assignments.            |
-| `agent__task_complete` | Mark a task done. Returns newly unblocked tasks and auto-dispatches agents. |
-| `agent__task_fail`     | Mark a task as failed. Dependents remain blocked.                           |
-
-```
-# Create tasks with dependency ordering
-agent__task_create --subject "Explore existing patterns"
-agent__task_create --subject "Implement feature" --blocked_by ["task_1"]
-agent__task_create --subject "Write tests" --blocked_by ["task_2"]
-
-# Mark tasks complete to unblock dependents
-agent__task_complete --task_id task_1
-```
-
-### Active Task Dispatch
-
-Tasks can optionally specify an agent to auto-spawn when the task becomes runnable:
-
-```
-agent__task_create \
-  --subject "Implement the auth module" \
-  --blocked_by ["task_1"] \
-  --agent coder \
-  --prompt "Implement auth module based on patterns found in task_1"
-```
-
-When `task_1` completes and the dependent task becomes unblocked, an agent is automatically spawned with the
-specified prompt. No manual intervention needed. This enables fully automated multi-step pipelines.
-
-### Output Summarization
-
-When a child agent produces long output, it can be automatically summarized before returning to the parent.
-This keeps parent context windows manageable.
-
- If the output exceeds `summarization_threshold` characters (default: 4000), it is sent through an LLM
-  summarization pass
- The `summarization_model` setting lets you use a cheaper/faster model for summarization (e.g. `gpt-4o-mini`)
- If `summarization_model` is not set, the parent's current model is used
- The summarization preserves all actionable information: code snippets, file paths, error messages, and
-  concrete recommendations
-
-### Teammate Messaging
-
-All agents (including children) automatically receive tools for **direct sibling-to-sibling messaging**:
-
-| Tool                  | Description                                         |
-|-----------------------|-----------------------------------------------------|
-| `agent__send_message` | Send a text message to another agent's inbox by ID. |
-| `agent__check_inbox`  | Drain all pending messages from your inbox.         |
-
-This enables coordination patterns where child agents share cross-cutting findings:
-
-```
-# Agent A discovers something relevant to Agent B
-agent__send_message --id agent_reviewer_b1c2d3e4 --message "Found a security issue in auth.rs line 42"
-
-# Agent B checks inbox before finalizing
-agent__check_inbox
-```
-
-Messages are routed through the parent's supervisor. A parent can message its children, and children can message
-their siblings. For a working example of the teammate pattern, see the built-in
-[code-reviewer](../assets/agents/code-reviewer) agent, which spawns file-specific reviewers that share
-cross-cutting findings with each other.
-
-### Runaway Safeguards
-
-The spawning system includes built-in safeguards to prevent runaway agent chains:
-
- **`max_concurrent_agents`:** Caps how many agents can run at once (default: 4). Spawn attempts beyond this
-  limit return an error asking the agent to wait or cancel existing agents.
- **`max_agent_depth`:** Caps nesting depth (default: 3). A child agent spawning its own child increments the
-  depth counter. Attempts beyond the limit are rejected.
- **`can_spawn_agents`:** Only agents with this flag set to `true` can spawn children. By default, spawning is
-  disabled. This means child agents cannot spawn their own children unless you explicitly create them with
-  `can_spawn_agents: true` in their config.
-
-## 8. User Interaction Tools
-
-Loki includes built-in tools for agents (and the REPL) to interactively prompt the user for input. These tools
-are **always available**. No configuration needed. They are automatically injected into every agent and into
-REPL mode when function calling is enabled.
-
-### User Interaction Available Tools
-
-| Tool             | Description                             | Returns                          |
-|------------------|-----------------------------------------|----------------------------------|
-| `user__ask`      | Present a single-select list of options | The selected option string       |
-| `user__confirm`  | Ask a yes/no question                   | `"yes"` or `"no"`                |
-| `user__input`    | Request free-form text input            | The text entered by the user     |
-| `user__checkbox` | Present a multi-select checkbox list    | Array of selected option strings |
-
-**Parameters:**
-
- `user__ask`: `--question "..." --options ["Option A", "Option B", "Option C"]`
- `user__confirm`: `--question "..."`
- `user__input`: `--question "..."`
- `user__checkbox`: `--question "..." --options ["Option A", "Option B", "Option C"]`
-
-At the top level (depth 0), these tools render interactive terminal prompts directly using arrow-key navigation,
-checkboxes, and text input fields.
-
-### Escalation (Sub-Agent to User)
-
-When a **child agent** (depth > 0) calls a `user__*` tool, it cannot prompt the terminal directly. Instead,
-the request is **automatically escalated** to the root agent:
-
-1. The child agent calls `user__ask(...)` and **blocks**, waiting for a reply
-2. The root agent sees a `pending_escalations` notification in its next tool results
-3. The root agent either answers from context or prompts the user itself, then calls
-   `agent__reply_escalation` to unblock the child
-4. The child receives the reply and continues
-
-The escalation timeout is configurable via `escalation_timeout` in the agent's `config.yaml` (default: 300
-seconds / 5 minutes). If the timeout expires, the child receives a fallback message asking it to use its
-best judgment.
-
-| Tool                      | Description                                                              |
-|---------------------------|--------------------------------------------------------------------------|
-| `agent__reply_escalation` | Reply to a pending child escalation, unblocking the waiting child agent. |
-
-This tool is automatically available to any agent with `can_spawn_agents: true`.
-
-## 9. Auto-Injected Prompts
-
-Loki automatically appends usage instructions to your agent's system prompt for each enabled built-in system.
-These instructions are injected into both **static and dynamic instructions** after your own instructions,
-ensuring agents always know how to use their available tools.
-
-| System             | Injected When                                                  | Toggle                      |
-|--------------------|----------------------------------------------------------------|-----------------------------|
-| Todo tools         | `auto_continue: true` AND `inject_todo_instructions: true`     | `inject_todo_instructions`  |
-| Spawning tools     | `can_spawn_agents: true` AND `inject_spawn_instructions: true` | `inject_spawn_instructions` |
-| Teammate messaging | Always (all agents)                                            | None (always injected)      |
-| User interaction   | Always (all agents)                                            | None (always injected)      |
-
-If you prefer to write your own instructions for a system, set the corresponding `inject_*` flag to `false`
-and include your custom instructions in the agent's `instructions` field. The built-in tools will still be
-available; only the auto-injected prompt text is suppressed.
-
-## Built-In Agents
-Loki comes packaged with some useful built-in agents:
-
-* `coder`: An agent to assist you with all your coding tasks
-* `code-reviewer`: A [CodeRabbit](https://coderabbit.ai)-style code reviewer that spawns per-file reviewers using the teammate messaging pattern
-* `demo`: An example agent to use for reference when learning to create your own agents
-* `explore`: An agent designed to help you explore and understand your codebase
-* `file-reviewer`: An agent designed to perform code-review on a single file (used by the `code-reviewer` agent)
-* `jira-helper`: An agent that assists you with all your Jira-related tasks
-* `oracle`: An agent for high-level architecture, design decisions, and complex debugging
-* `sisyphus`: A powerhouse orchestrator agent for writing complex code and acting as a natural language interface for your codebase (similar to ClaudeCode, Gemini CLI, Codex, or OpenCode). Uses sub-agent spawning to delegate to `explore`, `coder`, and `oracle`.
-* `sql`: A universal SQL agent that enables you to talk to any relational database in natural language

-# AIChat to Loki Migration Guide
-Loki originally started as a fork of AIChat but has since evolved into its own separate project with separate goals.
-
-As a result, there's some changes you'll need to make to your AIChat configuration to be able to use Loki.
-
-Be sure you've run `loki` at least once so that the Loki configuration directory and subdirectories exist and is
-populated with the built-in defaults.
-
-## Global Configuration File
-You should be able to copy/paste your AIChat configuration file into your Loki configuration directory. Since the 
-location of the Loki configuration directory varies between systems, you can use the following command to locate your
-config directory:
-
-```shell
-loki --info | grep 'config_dir' | awk '{print $2}'
-```
-
-Then, you'll need to make the following changes:
-
-* `function_calling` -> `function_calling_support`
-* `use_tools` -> `enabled_tools`
-* `agent_prelude` -> `agent_session`
-* `compress_threshold` -> `compression_threshold`
-* `summarize_prompt` -> `summarization_prompt`
-* `summary_prompt` -> `summary_context_prompt`
-
-## Roles
-Locate your `roles` directory using the following command:
-
-```shell
-loki --info | grep 'roles_dir' | awk '{print $2}'
-```
-
-Update any roles that have `use_tools` to `enabled_tools`.
-
-## Sessions
-Locate your `sessions` directory using the following command:
-
-```shell
-loki --info | grep 'sessions_dir' | awk '{print $2}'
-```
-
-Update the following settings:
-* `use_tools` -> `enabled_tools`
-* `compress_threshold` -> `compression_threshold`
-* `summarize_prompt` -> `summarization_prompt`
-* `summary_prompt` -> `summary_context_prompt`
-
---
-
-# LLM Functions Changes
-Probably the most significant difference between AIChat and Loki is how tools are handled. So if you cloned the 
-[llm-functions](https://github.com/sigoden/llm-functions) repo, you'll need to make the following changes.
-
-**Note: JavaScript functions are not supported in Loki.**
-
-The following guide assumes you're using the `llm-functions` repository as your base for custom functions, and thus
-follows that directory structure.
-
-## Agents
-Agents are now all handled in one place: the `agents` directory (`<loki-config-dir>/agents`):
-
-```shell
-loki --info | grep 'agents_dir' | awk '{print $2}'
-```
-
-And instead of separate `index.yaml` and `config.yaml` files, they're now both in a single `config.yaml` file.
-
-So now for all of your agents, copy all the contents of those directories to the corresponding directory in the Loki 
-`agents` directory. Then make the following changes:
-
-* Copy the contents of your `<aichat-config-dir>/functions/agents` directory into `<loki-config-dir/agents`
-* Merge `index.yaml` into `config.yaml`
-  * If you never created a custom `config.yaml` file, then simply rename `index.yaml` to `config.yaml`
-  * If you've defined an `agent_prelude`, rename that field to `agent_session`
-* Convert all JavaScript tools to either Python or Bash
-* For Bash `tools.sh`: Remove the following line:
-  ```bash
-  eval "$(argc --argc-eval "$0" "$@")"
-  ```
-* Any `tools.txt` files you have that define what global functions the agent uses is now replaced by the `global_tools`
-  field in the agent's `config.yaml`. So for example: If your `tools.txt` looks like this:
-  ```text
-  fs_mkdir.sh
-  fs_ls.sh
-  fs_patch.sh
-  fs_cat.sh
-  ```
-  then you need to add the following to your agent's `config.yaml`:
-  ```yaml
-  global_tools:
-    - fs_mkdir.sh
-    - fs_ls.sh
-    - fs_patch.sh
-    - fs_cat.sh
-  ```
-* If you have any bash `tools.sh` that depend on the utility scripts in the `llm-functions` repository, they've been 
-  replaced by built-in utility scripts. So use the following to replace any matching lines in your `tools.sh` files:
-  ```bash
-  ##################
-  ## Scripts file ##
-  ##################
-  ROOT_DIR="${LLM_ROOT_DIR:-$(cd "$(dirname "${BASH_SOURCE[0]}")/.." && pwd)}"
-  # replace with
-  source "$LLM_PROMPT_UTILS_FILE"
-  
-  #######################
-  ## guard_path script ##
-  #######################
-  "$ROOT_DIR/utils/guard_path.sh"
-  # replace with
-  guard_path
-  
-  ############################
-  ## guard_operation script ##
-  ############################
-  "$ROOT_DIR/utils/guard_operation.sh"
-  # replace with
-  guard_operation
-  
-  ######################
-  ## patch.awk script ##
-  ######################
-  awk -f "$ROOT_DIR/utils/patch.awk"
-  # replace with
-  patch_file
-  ```
-  
-When you're done with this migration, you should have the following:
-
-* No more `functions/agents` directory
-* No `functions/agents.txt` file (Loki assumes that if the agent directory exists, it is loadable)
-* No `<loki-config-dir>/agents/<agent-name>/tools.txt`
-* No `<loki-config-dir>/agents/<agent-name>/index.yaml`
-
-## Functions
-Loki consolidates much of the `llm-functions` repo functionality into one binary. So this means
-
-* There's no need to have `argc` installed anymore
-* No separate repository to manage
-* No `tools.txt`
-* No `functions.json`
-* No `functions/mcp` directory at all
-* No `functions/scripts`
-
-Here's how to migrate your functions over to Loki from the `llm-functions` repository.
-
-* Copy your AIChat `<aichat-config-dir>/functions` directory into your Loki config directory
-* Delete the following files and directories from your `<loki-config-dir>/functions` directory:
-  * `scripts/`
-  * `agents.txt`
-  * `functions.json`
-  * `Argcfile.sh`
-  * `README.md` (irrelevant now)
-  * `LICENSE` (irrelevant now)
-  * `utils/guard_operation.sh`
-  * `utils/guard_path.sh`
-  * `utils/patch.awk`
-* Everything in `tools.txt` now lives in the global config file under the `visible_tools` setting:
-  ```text
-  get_current_weather.sh
-  execute_command.sh
-  web_search.sh
-  #execute_py_code.py
-  query_jira_issues.sh
-  ```
-  becomes the following in your `<loki-config-dir>/config.yaml`
-  ```yaml
-  visible_tools:
-    - get_current_weather.sh
-    - execute_command.sh
-    - web_search.sh
-    # - web_search.sh
-    - query_jira_issues.sh
-  ```
-* If you've defined a `functions/mcp.json` file, you can leave it alone.
-* Similarly to agents, if you have any bash `tools.sh` that depend on the utility scripts in the `llm-functions` 
-  repository, they've been replaced by built-in utility scripts. So use the following to replace any matching lines in 
-  your `tools.sh` files:
-  ```bash
-  ##################
-  ## Scripts file ##
-  ##################
-  ROOT_DIR="${LLM_ROOT_DIR:-$(cd "$(dirname "${BASH_SOURCE[0]}")/.." && pwd)}"
-  # replace with
-  source "$LLM_PROMPT_UTILS_FILE"
-  
-  #######################
-  ## guard_path script ##
-  #######################
-  "$ROOT_DIR/utils/guard_path.sh"
-  # replace with
-  guard_path
-  
-  ############################
-  ## guard_operation script ##
-  ############################
-  "$ROOT_DIR/utils/guard_operation.sh"
-  # replace with
-  guard_operation
-  
-  ######################
-  ## patch.awk script ##
-  ######################
-  awk -f "$ROOT_DIR/utils/patch.awk"
-  # replace with
-  patch_file
-  ```
-

-tools in Loki without needing to use `argc`.

-Loki is designed to be highly dynamic and customizable. As a result, Loki utilizes a number of environment variables
-that can be used to modify its behavior at runtime without needing to modify the existing configuration files.
-
-Loki also supports defining environment variables via a `.env` file in the Loki configuration directory. This directory
-varies between systems, so you can find the location of your configuration directory using the following command:
-
-```shell
-loki --info | grep 'config_dir' | awk '{print $2}'
-```

-# Macros
-Macros are essentially Loki "scripts"; that is, a predefined sequence of REPL commands that automate repetitive tasks or
-workflows. Macros run in isolated environments, ensuring that the macros don't inherit any pre-existing role, session, 
-RAG, or agent state, and they will not affect your current context. 
-
-This isolation ensures that your workspace remains clean and unaffected by macro operations.
-
-![Macro Example](./images/macros/macros-example.gif)

-For more information on Loki's REPL, refer to the [REPL](./REPL.md) documentation.

-
-## Macro Definition
-Macros are defined as YAML files in the `macros` subdirectory of your Loki configuration directory. The Loki configuration 
-directory can vary between systems, so to find the location of your macros config directory, you can use the following 
-command:
-
-```shell
-loki --info | grep 'macros_dir' | awk '{print $2}'
-```
-
-Macro definitions are broken into two parts: the `steps` of the macro, and an optional `variables` section that lets 
-users pass in variables to alter the behavior of the macro at runtime.
-
-### Step Definitions
-The step definitions for a macro are straightforward: They are simply the exact commands you would otherwise type in the
-REPL. 
-
-**Example: Macro to generate a git commit message**
-`macros/generate-commit-message.yaml`
-```yaml
-steps:
-  - .file `git diff` -- generate git commit message
-```
-Usage:
-```shell
-$ loki --macro generate-commit-message
->> .file `git diff` -- generate a git commit message
-Add documentation on macros
-```
-
-For a full example configuration, refer to the [example macro configuration file](../config.macro.example.yaml) in the root of this project.
-
-### Macro Variables
-Sometimes it's useful to be able to modify the behavior of a macro at runtime. This is achieved with the `variables` 
-array of the macro definition.
-
-To pass variables to a macro, since they are just Loki scripts, the syntax is the same as it is for any other scripting 
-language: You just pass them alongside your invocation.
-
-**Example:**
-```shell
-$ loki --macro example-variable-macro first_argument second_argument
-```
-
-Each variable in the `variables` array has the following properties:
-* `name` (Required): the name of the variable, which can be referenced in the actual steps of the macro using the 
-  `{{name}}` syntax.
-* `default` (Optional): A default value for the variable if no value is specified. If no default value is defined, and 
-  no value is provided for the variable at runtime, Loki will error out.
-* `rest` (Optional, Boolean): When set to `true`, this variable will collect all remaining arguments passed to the 
-  macro. This behavior is only applicable when the variable is the last variable in the list. By default, this is 
-  `false`.
-
-The `variables` array is order-dependent; that is to say that all arguments passed to the macro are positional. So be
-careful about the ordering if that is important to your macro's invocation.
-
-**Example: Simple variable example to invoke an agent**
-`macros/invoke-agent.yaml`
-```yaml
-variables:
-  - name: agent                 # No default value means this must be defined at runtime
-  - name: args
-    rest: true                  # All remaining arguments to the macro are collected into this variable
-    default: What can you do?   # This is used if no value is passed at runtime
-steps:
-  - .agent {{agent}}
-  - '{{args}}'
-```
-Usage:
-```shell
-$ loki --macro invoke-agent sql
-# or
-$ loki --macro invoke-agent sql What tables are available?
-```
-
-For a full example configuration, refer to the [example macro configuration file](../config.macro.example.yaml) in the root of this project.
-
-## Built-In Macros
-Loki comes packaged with some useful built-in macros. These are also good examples if you're looking for more examples 
-on how to make your own macros, so be sure to check out the [built-in macro definitions](../assets/macros) if you're 
-looking for more examples.

-# Phase 1 Flow Test Plan
-
-Comprehensive behavioral verification plan comparing the old codebase
-(`~/code/testing/loki` on `develop` branch) against the new Phase 1
-codebase (`~/code/loki`). Every test should produce identical behavior
-in both codebases unless noted as an intentional improvement.
-
-## How to run
-
-For each test case:
-1. Run the test in the OLD codebase (`cd ~/code/testing/loki && cargo run --`)
-2. Run the same test in the NEW codebase (`cd ~/code/loki && cargo run --`)
-3. Compare output/behavior
-4. Mark PASS/FAIL/IMPROVED

-Legend:
- `OLD:` = expected behavior from old codebase
- `NEW:` = expected behavior from new codebase (should match unless noted)
- `[IMPROVED]` = intentional behavioral improvement in new code

-
-## Test Execution Notes
-
- Run tests in order — some depend on state from previous tests
-  (e.g., session tests create sessions that later tests reference)
- For MCP tests, ensure at least one MCP server is configured in
-  `~/.config/loki/functions/mcp.json`
- For agent tests, use built-in agents (coder, demo, explore)
- For sub-agent tests, use the sisyphus agent (has can_spawn_agents)
- For RAG tests, configure a RAG with test documents
- For vault tests, use temporary secret names to avoid polluting
-  the real vault
- Compare error messages between old and new — they may differ
-  slightly in wording but should convey the same meaning

-# Phase 2 Implementation Plan: Engine + Emitter
-
-## Overview
-
-Phase 1 splits `Config` into `AppState` + `RequestContext`. Phase 2 takes the unified state and introduces the **Engine** — a single core function that replaces CLI's `start_directive()` and REPL's `ask()` — plus an **Emitter trait** that abstracts output away from direct stdout writes. After this phase, CLI and REPL both call `Engine::run()` with different `Emitter` implementations and behave identically to today. The API server in Phase 4 will plug in without touching core logic.
-
-**Estimated effort:** ~1 week
-**Risk:** Low-medium. The work is refactoring existing well-tested code paths into a shared shape. Most of the risk is in preserving exact terminal rendering behavior.
-**Depends on:** Phase 1 Steps 0–10 complete (`GlobalConfig` eliminated, `RequestContext` wired through all entry points).
-
---
-
-## Why Phase 2 Exists
-
-Today's CLI and REPL have two near-identical pipelines that diverge in five specific places. The divergences are accidents of history, not intentional design:
-
-1. **Streaming flag handling.** `start_directive` forces non-streaming when extracting code; `ask` never extracts code.
-2. **Auto-continuation loop.** `ask` has complex logic for `auto_continue_count`, todo inspection, and continuation prompt injection. `start_directive` has none.
-3. **Session compression.** `ask` triggers `maybe_compress_session` and awaits completion; `start_directive` never compresses.
-4. **Session autoname.** `ask` calls `maybe_autoname_session` after each turn; `start_directive` doesn't.
-5. **Cleanup on exit.** `start_directive` calls `exit_session()` at the end; `ask` lets the REPL loop handle it.
-
-Four of these five divergences are bugs waiting to happen — they mean agents behave differently in CLI vs REPL mode, sessions don't get compressed in CLI even when they should, and auto-continuation is silently unavailable from the CLI. Phase 2 collapses both pipelines into one `Engine::run()` that handles all five behaviors uniformly, with per-request flags to control what's active (e.g., `auto_continue: bool` on `RunRequest`).
-
-The Emitter trait exists to decouple the rendering pipeline from its destination. Today, streaming output is hardcoded to write to the terminal via `crossterm`. An `Emitter` implementation can also feed an axum SSE stream, collect events for a JSON response, or capture everything for a test. The Engine sends semantic events; Emitters decide how to present them.

-## Core Types
-
-### `Engine`
-
-```rust
-pub struct Engine {
-    pub app: Arc<AppState>,
-}
-
-impl Engine {
-    pub fn new(app: Arc<AppState>) -> Self { Self { app } }
-
-    pub async fn run(
-        &self,
-        ctx: &mut RequestContext,
-        req: RunRequest,
-        emitter: &dyn Emitter,
-    ) -> Result<RunOutcome, CoreError>;
-}
-```
-
-`Engine` is intentionally a thin wrapper around `Arc<AppState>`. All per-turn state lives on `RequestContext`, so the engine itself has no per-call fields. This makes it cheap to clone and makes `Engine::run` trivially testable.
-
-### `RunRequest`
-
-```rust
-pub struct RunRequest {
-    pub input: Option<UserInput>,
-    pub command: Option<CoreCommand>,
-    pub options: RunOptions,
-}
-
-pub struct UserInput {
-    pub text: String,
-    pub files: Vec<FileInput>,
-    pub media: Vec<MediaInput>,
-    pub continuation: Option<ContinuationKind>,
-}
-
-pub enum ContinuationKind {
-    Continue,
-    Regenerate,
-}
-
-pub struct RunOptions {
-    pub stream: Option<bool>,
-    pub extract_code: bool,
-    pub auto_continue: bool,
-    pub compress_session: bool,
-    pub autoname_session: bool,
-    pub apply_prelude: bool,
-    pub with_embeddings: bool,
-    pub cancel: CancellationToken,
-}
-
-impl RunOptions {
-    pub fn cli() -> Self { /* today's start_directive defaults */ }
-    pub fn repl_turn() -> Self { /* today's ask defaults */ }
-    pub fn api_oneshot() -> Self { /* API one-shot defaults */ }
-    pub fn api_session() -> Self { /* API session defaults */ }
-}
-```
-
-Two things to notice:
-
-1. **`input` is `Option`.** A `RunRequest` can carry just a `command` (e.g., `.role explain`) with no user text, just an input (a plain prompt), or both (the `.role <name> <text>` form that activates a role and immediately sends a prompt through it). The engine handles all three shapes with one code path.
-
-2. **`RunOptions` is the knob panel that replaces the five divergences.** CLI today has `auto_continue: false, compress_session: false, autoname_session: false`; REPL has all three `true`. Phase 2 exposes these as explicit options with factory constructors for each frontend's conventional defaults. This also means you can now run a CLI one-shot with auto-continuation by constructing `RunOptions::cli()` and flipping `auto_continue = true` — a capability that doesn't exist today.
-
-### `CoreCommand`

-```rust

-    Role(String),
-    Session(String),
-    Rag(String),
-    Macro(String),
-    AgentData(String),
-}
-```
-
-This enum captures all 37 dot-commands identified in the explore. Three categories deserve special attention:
-
- **LLM-triggering commands** (`UsePrompt`, `UseRole` with trailing_text, `IncludeFiles` with trailing_text, `StarterRun`, `Macro` that contains LLM calls, and the continuation variants `Continue`/`Regenerate` expressed via `UserInput.continuation`) — these don't just mutate state; they produce a full run through the LLM pipeline. The engine treats them as `RunRequest { command: Some(_), input: Some(_), .. }` — command runs first, then input flows through.
-
- **Asynchronous commands that return immediately** (`EditConfig`, `EditRole`, `EditRagDocs`, `EditAgentConfig`, most `Vault*`, `Delete`) — these are side-effecting but don't produce an LLM interaction. The engine handles them, emits a `Result` event, and returns without invoking the LLM path.
-
- **Context-dependent commands** (`ClearTodo`, `StarterList`, `StarterRun`, `EditAgentConfig`, etc.) — these require a specific scope (e.g., active agent). The engine validates the precondition before executing and returns a `CoreError::InvalidState { expected: "active agent" }` if the precondition fails.
-
-### `Emitter` trait and `Event` enum
-
-```rust
-#[async_trait]
-pub trait Emitter: Send + Sync {
-    async fn emit(&self, event: Event<'_>) -> Result<(), EmitError>;
-}
-
-pub enum Event<'a> {
-    // Lifecycle
-    Started { request_id: Uuid, session_id: Option<SessionId>, agent: Option<&'a str> },
-    Finished { outcome: &'a RunOutcome },
-
-    // Assistant output
-    AssistantDelta(&'a str),
-    AssistantMessageEnd { full_text: &'a str },
-
-    // Tool calls
-    ToolCall { id: &'a str, name: &'a str, args: &'a str },
-    ToolResult { id: &'a str, name: &'a str, result: &'a str, is_error: bool },
-
-    // Auto-continuation
-    AutoContinueTriggered { count: usize, max: usize, remaining_todos: usize },
-
-    // Session lifecycle signals
-    SessionCompressing,
-    SessionCompressed { tokens_saved: Option<usize> },
-    SessionAutonamed(&'a str),
-
-    // Informational
-    Info(&'a str),
-    Warning(&'a str),
-
-    // Errors
-    Error(&'a CoreError),
-}
-
-pub enum EmitError {
-    ClientDisconnected,
-    WriteFailed(std::io::Error),
-}
-```
-
-Three implementations ship in Phase 2; two are stubs, one is real:
-
- **`TerminalEmitter`** (real) — wraps today's `SseHandler` → `markdown_stream`/`raw_stream` path. This is the bulk of Phase 2's work; see "Terminal rendering details" below.
- **`NullEmitter`** (stub, for tests) — drops all events on the floor.
- **`CollectingEmitter`** (stub, for tests and future JSON API) — appends events to a `Vec<OwnedEvent>` for later inspection.
-
-The `JsonEmitter` and `SseEmitter` implementations land in **Phase 4** when the API server comes online.
-
-### `RunOutcome`
-
-```rust
-pub struct RunOutcome {
-    pub request_id: Uuid,
-    pub session_id: Option<SessionId>,
-    pub final_message: Option<String>,
-    pub tool_call_count: usize,
-    pub turns: usize,
-    pub compressed: bool,
-    pub autonamed: Option<String>,
-    pub auto_continued: usize,
-}
-```
-
-`RunOutcome` is what CLI/REPL ignore but the future API returns as JSON. It records everything the caller might want to know about what happened during the run.
-
-### `CoreError`
-
-```rust
-pub enum CoreError {
-    InvalidRequest { msg: String },
-    InvalidState { expected: String, found: String },
-    NotFound { what: String, name: String },
-    Cancelled,
-    ProviderError { provider: String, msg: String },
-    ToolError { tool: String, msg: String },
-    EmitterError(EmitError),
-    Io(std::io::Error),
-    Other(anyhow::Error),
-}
-
-impl CoreError {
-    pub fn is_retryable(&self) -> bool { /* ... */ }
-    pub fn http_status(&self) -> u16 { /* for future API use */ }
-    pub fn terminal_message(&self) -> String { /* for TerminalEmitter */ }
-}
-```

-
-## Terminal Rendering Details
-
-The `TerminalEmitter` is the most delicate part of Phase 2 because it has to preserve every pixel of today's REPL/CLI behavior. Here's the mental model:
-
-**Today's flow:**
-```
-LLM client → mpsc::Sender<SseEvent> → SseHandler → render_stream
-                                                      ├─ markdown_stream (if highlight)
-                                                      └─ raw_stream (else)
-```
-
-Both `markdown_stream` and `raw_stream` write directly to stdout via `crossterm`, managing cursor positions, line clears, and incremental markdown parsing themselves.
-
-**Target flow:**
-```
-LLM client → mpsc::Sender<SseEvent> → SseHandler → TerminalEmitter::emit(Event::AssistantDelta)
-                                                      ├─ (internal) markdown_stream state machine
-                                                      └─ (internal) raw_stream state machine
-```
-
-The `TerminalEmitter` owns a `RefCell<StreamRenderState>` (or `Mutex` if we need `Send`) that wraps the existing `markdown_stream`/`raw_stream` state. Each `emit(AssistantDelta)` call feeds the chunk into this state machine exactly as `SseHandler`'s receive loop does today. The result is that the exact same crossterm calls happen in the exact same order — we've just moved them behind a trait.
-
-**Things that migrate 1:1 into `TerminalEmitter`:**
- Spinner start/stop on first delta
- Cursor positioning for line reprint during code block growth
- Syntax highlighting invocation via `MarkdownRender`
- Color/dim output for tool call banners
- Final newline + cursor reset on `AssistantMessageEnd`
-
-**Things that the engine handles, not the emitter:**
- Tool call *execution* (still lives in the engine loop)
- Session state mutations (engine calls `before_chat_completion` / `after_chat_completion` on `RequestContext`)
- Auto-continuation decisions (engine inspects agent runtime)
- Compression and autoname decisions (engine)
-
-**Things the emitter decides, not the engine:**
- Whether to suppress ToolCall rendering (sub-agents in today's code suppress their own output; TerminalEmitter respects a `verbose: bool` flag)
- How to format errors (TerminalEmitter uses colored stderr; JsonEmitter will use structured JSON)
- Whether to show a spinner at all (disabled for non-TTY output)
-
-**One gotcha:** today's `SseHandler` itself produces the `mpsc` channel that LLM clients push into. In the new model, `SseHandler` becomes an internal helper inside the engine's streaming path that converts `mpsc::Receiver<SseEvent>` into `Emitter::emit(Event::AssistantDelta(...))` calls. No LLM client code changes — they still push into the same channel type. Only the consumer side of the channel changes.

-## The Engine::run Pipeline
-
-Here's the full pipeline in pseudocode, annotated with which frontend controls each behavior via `RunOptions`:
-
-```rust
-impl Engine {
-    pub async fn run(
-        &self,
-        ctx: &mut RequestContext,
-        req: RunRequest,
-        emitter: &dyn Emitter,
-    ) -> Result<RunOutcome, CoreError> {
-        let request_id = Uuid::new_v4();
-        let mut outcome = RunOutcome::new(request_id);
-
-        emitter.emit(Event::Started { request_id, session_id: ctx.session_id(), agent: ctx.agent_name() }).await?;
-
-        // 1. Execute command (if any). Commands may be LLM-triggering, mutating, or informational.
-        if let Some(command) = req.command {
-            self.dispatch_command(ctx, command, emitter, &req.options).await?;
-        }
-
-        // 2. Early return if there's no user input (pure command)
-        let Some(user_input) = req.input else {
-            emitter.emit(Event::Finished { outcome: &outcome }).await?;
-            return Ok(outcome);
-        };
-
-        // 3. Apply prelude on first turn of a fresh context (CLI/REPL only)
-        if req.options.apply_prelude && !ctx.prelude_applied {
-            apply_prelude(ctx, &req.options.cancel).await?;
-            ctx.prelude_applied = true;
-        }
-
-        // 4. Build Input from user_input + ctx
-        let input = build_input(ctx, user_input, &req.options).await?;
-
-        // 5. Wait for any in-progress compression to finish (REPL-style block)
-        while ctx.is_compressing_session() {
-            tokio::time::sleep(Duration::from_millis(100)).await;
-        }
-
-        // 6. Enter the turn loop
-        self.run_turn(ctx, input, &req.options, emitter, &mut outcome).await?;
-
-        // 7. Maybe compress session
-        if req.options.compress_session && ctx.session_needs_compression() {
-            emitter.emit(Event::SessionCompressing).await?;
-            compress_session(ctx).await?;
-            outcome.compressed = true;
-            emitter.emit(Event::SessionCompressed { tokens_saved: None }).await?;
-        }
-
-        // 8. Maybe autoname session
-        if req.options.autoname_session {
-            if let Some(name) = maybe_autoname_session(ctx).await? {
-                outcome.autonamed = Some(name.clone());
-                emitter.emit(Event::SessionAutonamed(&name)).await?;
-            }
-        }
-
-        // 9. Auto-continuation (agents only)
-        if req.options.auto_continue {
-            if let Some(continuation) = self.check_auto_continue(ctx) {
-                emitter.emit(Event::AutoContinueTriggered { .. }).await?;
-                outcome.auto_continued += 1;
-                // Recursive call with continuation prompt
-                let next_req = RunRequest {
-                    input: Some(UserInput::from_continuation(continuation)),
-                    command: None,
-                    options: req.options.clone(),
-                };
-                return Box::pin(self.run(ctx, next_req, emitter)).await;
-            }
-        }
-
-        emitter.emit(Event::Finished { outcome: &outcome }).await?;
-        Ok(outcome)
-    }
-
-    async fn run_turn(
-        &self,
-        ctx: &mut RequestContext,
-        mut input: Input,
-        options: &RunOptions,
-        emitter: &dyn Emitter,
-        outcome: &mut RunOutcome,
-    ) -> Result<(), CoreError> {
-        loop {
-            outcome.turns += 1;
-
-            before_chat_completion(ctx, &input);
-
-            let client = input.create_client(ctx)?;
-            let (output, tool_results) = if should_stream(&input, options) {
-                stream_chat_completion(ctx, &input, client, emitter, &options.cancel).await?
-            } else {
-                buffered_chat_completion(ctx, &input, client, options.extract_code, &options.cancel).await?
-            };
-
-            after_chat_completion(ctx, &input, &output, &tool_results);
-            outcome.tool_call_count += tool_results.len();
-
-            if tool_results.is_empty() {
-                outcome.final_message = Some(output);
-                return Ok(());
-            }
-
-            // Emit each tool call and result
-            for result in &tool_results {
-                emitter.emit(Event::ToolCall { .. }).await?;
-                emitter.emit(Event::ToolResult { .. }).await?;
-            }
-
-            // Loop: feed tool results back in
-            input = input.merge_tool_results(output, tool_results);
-        }
-    }
-}
-```
-
-**Key design decisions in this pipeline:**
-
-1. **Command dispatch happens first.** A `RunRequest` that carries both a command and input runs the command first (mutating `ctx`), then the input flows through the now-updated context. This lets `.role explain "tell me about X"` work as a single atomic operation — the role is activated, then the prompt is sent under the new role.
-
-2. **Tool loop is iterative, not recursive.** Today both `start_directive` and `ask` recursively call themselves after tool results. The new `run_turn` uses a `loop` instead, which is cleaner, avoids stack growth on long tool chains, and makes cancellation handling simpler. Auto-continuation remains recursive because it's a full new turn with a new prompt, not just a tool-result continuation.
-
-3. **Cancellation is checked at every await point.** `options.cancel: CancellationToken` is threaded into every async call. On cancellation, the engine emits `Event::Error(CoreError::Cancelled)` and returns. Today's `AbortSignal` pattern gets wrapped in a `CancellationToken` adapter during the migration.
-
-4. **Session state hooks fire at the same points as today.** `before_chat_completion` and `after_chat_completion` continue to exist on `RequestContext`, called from the same places in the same order. The refactor doesn't change their semantics.
-
-5. **Emitter errors don't abort the run.** If the emitter's output destination disconnects (client closes browser tab), the engine keeps running to completion so session state is correctly persisted, but it stops emitting events. The `EmitError::ClientDisconnected` case is special-cased to swallow subsequent emits. Session save + tool execution still happen.
-
---
-
-## Migration Strategy
-
-This phase is structured as **extract, unify, rewrite frontends** — similar to Phase 1's facade pattern. The old functions stay in place until the new Engine is proven by tests and manual verification.
-
-### Step 1: Create the core types
-
-Add the new files without wiring them into anything:
-
- `src/engine/mod.rs` — module root
- `src/engine/engine.rs` — `Engine` struct + `run` method (initially `unimplemented!()`)
- `src/engine/request.rs` — `RunRequest`, `UserInput`, `RunOptions`, `ContinuationKind`, `RunOutcome`
- `src/engine/command.rs` — `CoreCommand` enum + sub-enums
- `src/engine/error.rs` — `CoreError` enum
- `src/engine/emitter.rs` — `Emitter` trait + `Event` enum + `EmitError`
- `src/engine/emitters/mod.rs` — emitter module
- `src/engine/emitters/null.rs` — `NullEmitter` (test stub)
- `src/engine/emitters/collecting.rs` — `CollectingEmitter` (test stub)
- `src/engine/emitters/terminal.rs` — `TerminalEmitter` (initially `unimplemented!()`)
-
-Register `pub mod engine;` in `src/main.rs`. Code compiles but nothing calls it yet.
-
-**Verification:** `cargo check` clean, `cargo test` passes.
-
-### Step 2: Implement `TerminalEmitter` against existing render code
-
-Before wiring the engine, build the `TerminalEmitter` by wrapping today's `SseHandler` + `markdown_stream` + `raw_stream` + `MarkdownRender` + `Spinner` code. Don't change any of those modules — just construct a `TerminalEmitter` that holds the state they need and forwards `emit(Event::AssistantDelta(...))` into them.
-
-```rust
-pub struct TerminalEmitter {
-    render_state: Mutex<StreamRenderState>,
-    options: TerminalEmitterOptions,
-}
-
-pub struct TerminalEmitterOptions {
-    pub highlight: bool,
-    pub theme: Option<String>,
-    pub verbose_tool_calls: bool,
-    pub show_spinner: bool,
-}
-
-impl TerminalEmitter {
-    pub fn new_from_app(app: &AppState, working_mode: WorkingMode) -> Self { /* ... */ }
-}
-```
-
-Implement `Emitter` for it, mapping each `Event` variant to the appropriate crossterm operation:
-
-| Event | TerminalEmitter action |
-|---|---|
-| `Started` | Start spinner |
-| `AssistantDelta(chunk)` | Stop spinner (if first), feed chunk into render state |
-| `AssistantMessageEnd { full_text }` | Flush render state, emit trailing newline |
-| `ToolCall { name, args }` | Print dimmed `⚙ Using <name>` banner if verbose |
-| `ToolResult { .. }` | Print dimmed result summary if verbose |
-| `AutoContinueTriggered` | Print yellow `⟳ Continuing (N/M, R todos remaining)` to stderr |
-| `SessionCompressing` | Print `Compressing session...` to stderr |
-| `SessionCompressed` | Print `Session compressed.` to stderr |
-| `SessionAutonamed` | Print `Session auto-named: <name>` to stderr |
-| `Info(msg)` | Print to stdout |
-| `Warning(msg)` | Print yellow to stderr |
-| `Error(e)` | Print red to stderr |
-| `Finished` | No-op (ensures trailing newline is flushed) |
-
-**Verification:** write integration tests that construct a `TerminalEmitter`, feed it a sequence of events manually, and compare captured stdout/stderr to golden outputs. Use `assert_cmd` or similar to snapshot the rendered output of each event variant.
-
-### Step 3: Implement `Engine::run` without wiring it
-
-Implement `Engine::run` and `Engine::run_turn` following the pseudocode above. Use the existing helper functions (`before_chat_completion`, `after_chat_completion`, `apply_prelude`, `create_client`, `call_chat_completions`, `call_chat_completions_streaming`, `maybe_compress_session`, `maybe_autoname_session`) unchanged, just called through `ctx` instead of `&GlobalConfig`.
-
-**Implementing `dispatch_command`** is the largest sub-task here because it needs to match all 37 `CoreCommand` variants and invoke the right `ctx` methods. Most variants are straightforward one-liners that call a corresponding method on `RequestContext`. A few need special handling:
-
- `CoreCommand::UseRole { name, trailing_text }` — activate role, then if `trailing_text` is `Some`, the outer `run` will flow through with the trailing text as `UserInput.text`.
- `CoreCommand::IncludeFiles` — reads files, converts to `FileInput` list, attaches to `ctx`'s next input (or fails if no input is provided).
- `CoreCommand::StarterRun(id)` — looks up the starter text on the active agent, fails if no agent.
- `CoreCommand::Macro` — delegates to `macro_execute`, which may itself call `Engine::run` internally for LLM-triggering macros.
-
-**Verification:** write unit tests for `dispatch_command` using `NullEmitter`. Each test activates a command and asserts the expected state mutation on `ctx`. This is ~37 tests, one per variant, and they catch the bulk of regressions early.
-
-Then write a handful of integration tests for `Engine::run` with `CollectingEmitter`, asserting the expected event sequence for:
- Plain prompt, no tools, streaming
- Plain prompt, no tools, non-streaming
- Prompt that triggers 2 tool calls
- Prompt that triggers auto-continuation (mock the LLM response)
- Prompt on a session that crosses the compression threshold
- Command-only request (`.info`)
- Command + prompt request (`.role explain "..."`)
-
-### Step 4: Wire CLI to `Engine::run`
-
-Replace `main.rs::start_directive` with a thin wrapper:
-
-```rust
-async fn start_directive(
-    app: Arc<AppState>,
-    ctx: &mut RequestContext,
-    input_text: String,
-    files: Vec<String>,
-    code_mode: bool,
-) -> Result<()> {
-    let engine = Engine::new(app.clone());
-    let emitter = TerminalEmitter::new_from_app(&app, WorkingMode::Cmd);
-
-    let req = RunRequest {
-        input: Some(UserInput::from_text_and_files(input_text, files)),
-        command: None,
-        options: {
-            let mut o = RunOptions::cli();
-            o.extract_code = code_mode && !*IS_STDOUT_TERMINAL;
-            o
-        },
-    };
-
-    match engine.run(ctx, req, &emitter).await {
-        Ok(_outcome) => Ok(()),
-        Err(CoreError::Cancelled) => Ok(()),
-        Err(e) => Err(e.into()),
-    }
-}
-```
-
-**Verification:** manual smoke test. Run `loki "hello"`, `loki --code "write a rust hello world"`, `loki --role explain "what is TCP"`. All should produce identical output to before the change.
-
-### Step 5: Wire REPL to `Engine::run`
-
-Replace `repl/mod.rs::ask` with a wrapper that calls the engine. The REPL's outer loop that reads lines and calls `run_repl_command` stays. `run_repl_command` for non-dot-command lines constructs a `RunRequest { input: Some(...), .. }` and calls `Engine::run`. Dot-commands get parsed into `CoreCommand` and called as `RunRequest { command: Some(...), input: None, .. }` (or with input if they carry trailing text).
-
-```rust
-// In Repl:
-async fn handle_line(&mut self, line: &str) -> Result<()> {
-    let req = if let Some(rest) = line.strip_prefix('.') {
-        parse_dot_command_to_run_request(rest, &self.ctx)?
-    } else {
-        RunRequest {
-            input: Some(UserInput::from_text(line.to_string())),
-            command: None,
-            options: RunOptions::repl_turn(),
-        }
-    };
-
-    match self.engine.run(&mut self.ctx, req, &self.emitter).await {
-        Ok(_) => Ok(()),
-        Err(CoreError::Cancelled) => Ok(()),
-        Err(e) => {
-            self.emitter.emit(Event::Error(&e)).await.ok();
-            Ok(())
-        }
-    }
-}
-```
-
-**Verification:** manual smoke test of the REPL. Run through a typical session:
-1. `loki` → REPL starts
-2. `hello` → plain prompt works
-3. `.role explain` → role activates
-4. `what is TCP` → responds under the role
-5. `.session` → session starts
-6. Several messages → conversation continues
-7. `.info session` → info prints
-8. `.compress session` → compression runs
-9. `.agent sisyphus` → agent activates with sub-agents
-10. `write a hello world in rust` → tool calls + output
-11. `.exit agent` → agent exits, previous session still active
-12. `.exit` → REPL exits
-
-Every interaction should behave identically to pre-Phase-2. Any visual difference is a bug.
-
-### Step 6: Delete the old `start_directive` and `ask`
-
-Once CLI and REPL both route through `Engine::run` and all tests/smoke tests pass, delete the old function bodies. Remove any now-unused imports. Run `cargo check` and `cargo test`.
-
-**Verification:** full test suite green, no dead code warnings.
-
-### Step 7: Tidy and document
-
- Add rustdoc comments on `Engine`, `RunRequest`, `RunOptions`, `Emitter`, `Event`, `CoreCommand`, `CoreError`.
- Add an `examples/` subdirectory under `src/engine/` showing how to call the engine with each emitter.
- Update `docs/AGENTS.md` with a note that CLI now supports auto-continuation (since it's no longer a REPL-only feature).
- Update `docs/REST-API-ARCHITECTURE.md` to remove any "in Phase 2" placeholders.
-

-
-## Risks and Watch Items
-
-| Risk | Severity | Mitigation |
-|---|---|---|
-| **Terminal rendering regressions** | High | Golden-file snapshot tests for every `Event` variant. Manual smoke tests across all common REPL flows. Keep `TerminalEmitter` as a thin wrapper — no logic changes in the render code itself. |
-| **Auto-continuation recursion limits** | Medium | The new `Engine::run` uses `Box::pin` for the auto-continuation recursive call. Verify with a mock LLM that `max_auto_continues = 100` doesn't blow the stack. |
-| **Cancellation during tool execution** | Medium | Tool execution currently uses `AbortSignal`; the new path uses `CancellationToken`. Write a shim that translates. Write a test that cancels mid-tool-call and verifies graceful cleanup (no orphaned subprocesses, no leaked file descriptors). |
-| **Command parsing fidelity** | Medium | The dot-command parser in today's REPL is hand-written and has edge cases. Port the parsing code verbatim into a dedicated `parse_dot_command_to_run_request` function with unit tests for every edge case found in today's code. |
-| **Macro execution recursion** | Medium | `.macro` can invoke LLM calls, which now go through `Engine::run`, which can invoke more macros. Verify there's a recursion depth limit or cycle detection; add one if missing. |
-| **Emitter error propagation** | Low | Emitter errors (ClientDisconnected) should NOT abort session save logic. Engine must continue executing after the first `EmitError::ClientDisconnected` — just stop emitting. Write a test that simulates a disconnected emitter mid-response and asserts the session is still correctly persisted. |
-| **Spinner interleaving with tool output** | Low | Today's spinner is tightly coupled to the stream handler. If the new order of operations fires a tool call before the spinner is stopped, you'll get garbled output. Test this specifically. |
-| **Feature flag: `auto_continue` in CLI** | Low | After Phase 2, CLI *could* support auto-continuation but it's not exposed. Decision: leave it off by default in `RunOptions::cli()`, add a `--auto-continue` flag in a separate follow-up if desired. Don't sneak behavior changes into this refactor. |

-## What Phase 2 Does NOT Do
-
- **No new features.** Everything that worked before works the same way after.
- **No API server.** `JsonEmitter` and `SseEmitter` are placeholders — Phase 4 implements them.
- **No `SessionStore` abstraction.** That's Phase 3.
- **No `ToolScope` unification.** That landed in Phase 1 Step 6.5.
- **No changes to LLM client code.** `call_chat_completions` and `call_chat_completions_streaming` keep their existing signatures.
- **No MCP factory pooling.** That's Phase 5.
- **No dot-command syntax changes.** The REPL still accepts exactly the same dot-commands; they just parse into `CoreCommand` instead of being hand-dispatched in `run_repl_command`.
-
-The sole goal of Phase 2 is: **extract the pipeline into Engine::run, route CLI and REPL through it, and prove via tests and smoke tests that nothing regressed.**

-# Phase 3 Implementation Plan: SessionStore Abstraction
-
-## Overview
-
-Phase 3 extracts session persistence behind a trait so that CLI, REPL, and the future API server all resolve sessions through the same interface. The file-based YAML storage that exists today remains the only implementation in Phase 3 — no database, no schema migration, no new on-disk format. What changes is that session identity becomes **UUID-primary with optional name-based aliases**, direct `std::fs::write` calls disappear from `Session::save()`, and concurrent access to the same session is properly serialized.
-
-After Phase 3, Phase 4 (REST API) can plug in without touching any persistence code: `POST /v1/sessions` returns a UUID, subsequent requests address sessions by that UUID, and CLI/REPL users continue typing `.session my-project` without noticing the internal change.
-
-**Estimated effort:** ~3–5 days
-**Risk:** Low. Storage semantics don't change; we're re-shaping the API surface around existing YAML files.
-**Depends on:** Phase 1 complete, Phase 2 complete (Engine needs to call through the new store, not raw `Session::load`).
-
---
-
-## Why This Phase Exists
-
-Today's `Session::load()` and `Session::save()` embed the file layout, the filename-is-the-identity assumption, and the absence of concurrency control directly in the type. Three things break when you try to run this in a multi-tenant server:
-
-1. **No UUID identity.** Two API clients both start a "project" session and collide on the filename. You can't safely let clients name sessions freely.
-
-2. **No concurrency control.** Two concurrent requests to the same session do `load → mutate → save` with no coordination. The later save clobbers the earlier one's changes.
-
-3. **No abstraction seam.** Every callsite computes paths itself via `Config::session_file(name)` and calls `Session::load()` / `.save()` directly. There's no single place to swap in alternate storage, add caching, or instrument persistence.
-
-Phase 3 fixes all three without breaking anything users currently do.

-
-## Core Types
-
-### `SessionId`
-
-```rust
-#[derive(Copy, Clone, Eq, PartialEq, Hash, Debug, Serialize, Deserialize)]
-pub struct SessionId(Uuid);
-
-impl SessionId {
-    pub fn new() -> Self { Self(Uuid::new_v4()) }
-    pub fn as_uuid(&self) -> Uuid { self.0 }
-    pub fn to_string(&self) -> String { self.0.to_string() }
-    pub fn parse(s: &str) -> Result<Self, SessionIdError> { /* ... */ }
-}
-```
-
-UUID v4 by default. Newtype so we can't accidentally pass arbitrary strings where a session ID is expected, and so the on-disk format can evolve without breaking callers.
-
-### `SessionAlias`
-
-```rust
-#[derive(Clone, Eq, PartialEq, Hash, Debug)]
-pub struct SessionAlias(String);
-
-impl SessionAlias {
-    pub fn new(s: impl Into<String>) -> Result<Self, AliasError>;
-    pub fn as_str(&self) -> &str { &self.0 }
-}
-```
-
-Wraps the human-readable names users type in `.session my-project`. Validation rejects path traversal (`..`), slashes, null bytes, and anything that would produce an invalid filename. This is the CLI/REPL compatibility layer — existing `sessions/my-project.yaml` files continue to work, the alias system just maps them to auto-generated UUIDs on first access.
-
-### `SessionHandle`
-
-```rust
-pub struct SessionHandle {
-    id: SessionId,
-    alias: Option<SessionAlias>,
-    is_agent: Option<String>,
-    state: Arc<tokio::sync::Mutex<Session>>,
-    store: Arc<dyn SessionStore>,
-    dirty: Arc<AtomicBool>,
-}
-
-impl SessionHandle {
-    pub fn id(&self) -> SessionId { self.id }
-    pub fn alias(&self) -> Option<&SessionAlias> { self.alias.as_ref() }
-    pub async fn lock(&self) -> SessionGuard<'_>;
-    pub fn mark_dirty(&self);
-    pub async fn save(&self) -> Result<(), StoreError>;
-    pub async fn rename(&mut self, new_alias: SessionAlias) -> Result<(), StoreError>;
-}
-
-pub struct SessionGuard<'a> {
-    session: MutexGuard<'a, Session>,
-    handle: &'a SessionHandle,
-}
-
-impl SessionGuard<'_> {
-    pub fn get(&self) -> &Session { &self.session }
-    pub fn get_mut(&mut self) -> &mut Session {
-        self.handle.mark_dirty();
-        &mut self.session
-    }
-}
-```
-
-A `SessionHandle` is what callers pass around. It wraps:
- The stable `SessionId` (never changes after creation)
- An optional `SessionAlias` (can be renamed; users see this in `.info session`)
- An optional `is_agent` marker so the store knows which directory to read/write
- A shared `Arc<Mutex<Session>>` that serializes access within the process
- A backpointer to the store so `save()`, `rename()`, etc. work without the caller knowing the storage type
- A dirty flag that auto-sets on `get_mut()` and clears after successful save
-
-The `lock()` / `SessionGuard` pattern is important: it makes the "you must lock before touching state" rule compiler-enforced. Today's code mutates `Config.session` freely because the whole `Config` is behind an `RwLock`. After Phase 3, mutating a session requires going through `handle.lock().await.get_mut()`, which acquires the per-session mutex. Two concurrent requests to the same session serialize automatically.
-
-### `SessionStore` trait
-
-```rust
-#[async_trait]
-pub trait SessionStore: Send + Sync {
-    /// Create a new session. If `alias` is provided, register it in the
-    /// alias index. Fails with AliasInUse if the alias already exists.
-    async fn create(
-        &self,
-        agent: Option<&str>,
-        alias: Option<SessionAlias>,
-        initial: Session,
-    ) -> Result<SessionHandle, StoreError>;
-
-    /// Open an existing session by UUID.
-    async fn open(
-        &self,
-        agent: Option<&str>,
-        id: SessionId,
-    ) -> Result<SessionHandle, StoreError>;
-
-    /// Open an existing session by alias, or create it if it doesn't exist.
-    /// This is the CLI/REPL compatibility path.
-    async fn open_or_create_by_alias(
-        &self,
-        agent: Option<&str>,
-        alias: SessionAlias,
-        initial_factory: impl FnOnce() -> Session + Send,
-    ) -> Result<SessionHandle, StoreError>;
-
-    /// Resolve an alias to its UUID without loading the session.
-    async fn resolve_alias(
-        &self,
-        agent: Option<&str>,
-        alias: &SessionAlias,
-    ) -> Result<Option<SessionId>, StoreError>;
-
-    /// Persist the current in-memory state of a handle back to storage.
-    /// Atomically — no torn writes.
-    async fn save(&self, handle: &SessionHandle) -> Result<(), StoreError>;
-
-    /// Rename a session's alias. The UUID and session state are unchanged.
-    async fn rename(
-        &self,
-        handle: &SessionHandle,
-        new_alias: SessionAlias,
-    ) -> Result<(), StoreError>;
-
-    /// Delete a session permanently. Both the state file and any alias
-    /// pointing at it are removed.
-    async fn delete(
-        &self,
-        agent: Option<&str>,
-        id: SessionId,
-    ) -> Result<(), StoreError>;
-
-    /// List all sessions in a scope (global or per-agent). Returns UUIDs
-    /// paired with their aliases if any.
-    async fn list(
-        &self,
-        agent: Option<&str>,
-    ) -> Result<Vec<SessionMeta>, StoreError>;
-}
-
-pub struct SessionMeta {
-    pub id: SessionId,
-    pub alias: Option<SessionAlias>,
-    pub last_modified: SystemTime,
-    pub is_autoname: bool,
-}
-
-pub enum StoreError {
-    NotFound { id: Option<SessionId>, alias: Option<String> },
-    AliasInUse(String),
-    InvalidAlias(String),
-    Io(std::io::Error),
-    Serde(serde_yaml::Error),
-    Concurrent,  // best-effort optimistic check
-    Other(anyhow::Error),
-}
-```
-
-### `FileSessionStore`
-
-```rust
-pub struct FileSessionStore {
-    root: PathBuf,                                      // ~/.config/loki/
-    agents_root: PathBuf,                               // ~/.config/loki/agents/
-    handles: Mutex<HashMap<(Option<String>, SessionId), Weak<Mutex<Session>>>>,
-}
-```
-
-The `handles` map is the in-process cache that enforces "one `Arc<Mutex<Session>>` per live session per process." If two callers `open()` the same session, they get two `SessionHandle`s pointing at the same underlying mutex, so their locks serialize. When the last handle drops, the weak ref fails on the next lookup and the store re-reads from disk.
-
---
-
-## The On-Disk Layout
-
-### New layout (Phase 3 target)
-
-```
-~/.config/loki/sessions/
-  by-id/
-    <uuid>/
-      state.yaml
-  by-name/
-    my-project      → text file containing the UUID
-    another-chat    → text file containing the UUID
-```
-
-Agent sessions mirror this inside each agent's directory:
-
-```
-~/.config/loki/agents/sisyphus/sessions/
-  by-id/
-    <uuid>/
-      state.yaml
-  by-name/
-    my-project   → UUID
-```
-
-### Backward compatibility
-
-The migration is lazy and non-destructive. On `FileSessionStore` startup, we do NOT rewrite the directory. On the first `open_or_create_by_alias("my-project")` call, the store checks:
-
-1. **New layout hit:** is there a `by-name/my-project` alias file? Read the UUID, open `by-id/<uuid>/state.yaml`.
-2. **Legacy layout hit:** is there a `sessions/my-project.yaml`? Generate a fresh UUID, create `by-id/<uuid>/state.yaml` from the legacy content (atomic copy), write `by-name/my-project` pointing to the new UUID, and leave the legacy file in place. The legacy file becomes stale but untouched.
-3. **Neither:** create fresh.
-
-This means users upgrading from pre-Phase-3 builds never lose data, and they can downgrade during the migration window (their old files are still readable by the old code because we haven't deleted them). A `loki migrate sessions` command can later do a clean sweep to remove the legacy files — but that's an operational convenience, not a requirement of Phase 3.
-
-**Deleting a migrated session** (the `.delete` REPL command) also deletes the legacy file if it still exists, so users don't see orphan entries in `list_sessions()`.
-
-**Autoname temp sessions** (today: `sessions/_/20231201T123456-autoname.yaml`) map cleanly to the new layout — they get UUIDs like any other session, and their alias is the generated `20231201T123456-autoname` string. The `_/` prefix from today's path becomes a flag on `SessionMeta::is_autoname: true` set by the store when it recognizes the naming pattern during migration.
-
-### Atomic writes
-
-Today's `Session::save()` is `std::fs::write(path, yaml)` — if the process dies mid-write, you get a truncated YAML file that can't be loaded. The new `FileSessionStore::save()` uses the standard tempfile-and-rename pattern:
-
-```rust
-async fn save(&self, handle: &SessionHandle) -> Result<(), StoreError> {
-    let session = handle.state.lock().await;
-    let yaml = serde_yaml::to_string(&*session)?;
-    let target = self.state_path(handle.is_agent.as_deref(), handle.id);
-    let tmp = target.with_extension("yaml.tmp");
-    tokio::fs::write(&tmp, yaml).await?;
-    tokio::fs::rename(&tmp, &target).await?;
-    handle.dirty.store(false, Ordering::Release);
-    Ok(())
-}
-```
-
-`rename` is atomic on POSIX filesystems and on Windows NTFS (via `MoveFileEx`). Either the old content or the new content is visible to readers; never a half-written file.
-
---
-
-## Concurrency Model
-
-Three layers, each with a clear responsibility:
-
-1. **Process-level: per-session `Arc<Mutex<Session>>`.** Two handles to the same session share one mutex. Inside one process, concurrent access to the same session is serialized automatically. This is enough for CLI (single request) and REPL (single user, but multiple async tasks like background compression).
-
-2. **Inter-process: filesystem rename atomicity.** Two separate Loki processes (unlikely today but possible for someone running CLI and REPL simultaneously on the same state) can't corrupt files because writes go through tempfile+rename. The later writer wins cleanly; the earlier writer's changes are lost but the file is always readable.
-
-3. **Optimistic conflict detection (optional, Phase 5+):** If we later decide to add "you edited this session somewhere else, please reload" UX, we can add an `mtime` check on load/save and surface `StoreError::Concurrent` when the on-disk mtime doesn't match the value we read at `open()` time. This is deliberately not built in Phase 3 — it's a UX improvement for later, not a correctness requirement.
-
-For Phase 3, layers 1 and 2 together are sufficient for everything up through "many concurrent API sessions, each addressing different UUIDs." The one gap they don't cover is "multiple API requests on the same session UUID at the same time" — but the per-session mutex in layer 1 handles that by serializing them, which is the desired behavior. The second request waits its turn and sees the first request's updates.
-
---
-
-## Engine and Callsite Changes
-
-### Before Phase 3
-
-```rust
-// In REPL command handler:
-Config::use_session_safely(&config, Some("my-project"), abort_signal)?;
-// later:
-config.write().session.as_mut().unwrap().add_message(...);
-// later:
-Config::save_session_safely(&config, None)?;
-```
-
-### After Phase 3
-
-```rust
-// In CoreCommand::UseSession handler inside Engine::dispatch_command:
-let alias = SessionAlias::new("my-project")?;
-let handle = self.app.sessions.open_or_create_by_alias(
-    ctx.agent_name(),
-    alias,
-    || Session::new_default(ctx.model_id(), ctx.role_name()),
-).await?;
-ctx.session = Some(handle);
-
-// later, during the chat loop:
-{
-    let mut guard = handle.lock().await;
-    guard.get_mut().add_message(input, output);
-}
-handle.save().await?;  // fires when the turn completes
-```
-
-The `RequestContext.session: Option<Session>` field becomes `RequestContext.session: Option<SessionHandle>`. All 13 session-touching callsites from the explore get rewritten to go through the handle instead of direct access.
-
-### The 13 callsites and their new shapes
-
-| Current location | Current call | New call |
-|---|---|---|
-| `Config::use_session` | `Session::load` or `Session::new` | `store.open_or_create_by_alias(...)` |
-| `Config::use_session_safely` | take/replace pattern on `config.session` | `ctx.session = Some(handle)` |
-| `Config::exit_session` | `session.exit()` (maybe saves) | `if ctx.session.dirty() { handle.save().await? }; ctx.session = None` |
-| `Config::empty_session` | `session.clear_messages()` | `handle.lock().await.get_mut().clear_messages()` |
-| `Config::save_session` | `session.save()` with name logic | `handle.rename(alias)?; handle.save().await?` |
-| `Config::compress_session` | mutates session, relies on dirty flag | `handle.lock().await.get_mut().compress(...)?; handle.save().await?` |
-| `Config::maybe_autoname_session` | spawns task, mutates session | same, but via handle |
-| `Config::delete` (kind="session") | `remove_file` on path | `store.delete(agent, id).await?` |
-| `Config::after_chat_completion` | `session.add_message(...)` | via handle |
-| `Config::apply_prelude` | may `use_session` | via store |
-| `Agent::init` / `use_agent` | may load agent session | via store, with `agent=Some(name)` |
-| `.session` REPL command | via `use_session_safely` | via store |
-| `.delete session` REPL command | via `Config::delete` | via store |
-
-Most of these are one-liner changes since the store's API mirrors the semantics of today's methods. The subtle ones are:
-
- **`exit_session`** has "save if dirty and `save_session != Some(false)`" logic plus "prompt for name if temp session" UX. The prompt lives in the REPL layer (it calls `inquire::Text`), not in the store. After the refactor, the REPL reads the dirty flag from the handle, prompts for a name if needed, calls `handle.rename()` if the user provided one, then calls `handle.save()`.
-
- **`compress_session`** runs asynchronously today — it spawns a task that holds a clone of `GlobalConfig` and writes back via `config.write()`. After the refactor, the task holds an `Arc<SessionHandle>` and does `handle.lock().await.get_mut().compress(...)` followed by `handle.save().await`. The per-session mutex prevents the compression task from clobbering concurrent turn writes.
-
- **`maybe_autoname_session`** is the same story as compression: spawn task, mutate through handle, save through store.
-
---
-
-## Migration Strategy
-
-### Step 1: Create the types without wiring
-
-Add new files:
-
- `src/session/mod.rs` — module root
- `src/session/id.rs` — `SessionId`, `SessionAlias`
- `src/session/store.rs` — `SessionStore` trait, `StoreError`, `SessionMeta`
- `src/session/handle.rs` — `SessionHandle`, `SessionGuard`
- `src/session/file_store.rs` — `FileSessionStore` implementation
-
-Move the existing `Session` struct from `src/config/session.rs` to `src/session/session.rs`. Keep the pub re-export at `src/config::Session` so no external callers break during the migration. The struct itself is unchanged — same fields, same YAML format, same methods. This is purely a module reorganization.
-
-Register `pub mod session;` in `src/main.rs` and add `pub sessions: Arc<dyn SessionStore>` to `AppState`. Initialize it in `AppState::init()` with `FileSessionStore::new(config_dir)`.
-
-**Verification:** `cargo check` clean, `cargo test` passes. Nothing uses the new types yet.
-
-### Step 2: Implement `FileSessionStore` against the new layout
-
-Build the file-based implementation:
-
- `state_path(agent, id) → ~/.config/loki/[agents/<agent>/]sessions/by-id/<uuid>/state.yaml`
- `alias_path(agent, alias) → ~/.config/loki/[agents/<agent>/]sessions/by-name/<alias>`
- `legacy_path(agent, alias) → ~/.config/loki/[agents/<agent>/]sessions/<alias>.yaml`
-
-Implement `create`, `open`, `open_or_create_by_alias`, `resolve_alias`, `save`, `rename`, `delete`, `list`. The `open_or_create_by_alias` method is the most complex — it has the lazy-migration logic that checks new layout, then legacy layout, then falls through to creation.
-
-**Unit tests for `FileSessionStore`:**
- Create + open roundtrip
- Create with alias + open_or_create_by_alias finds it
- Lazy migration from legacy `.yaml` file
- Delete removes both new and legacy paths
- Rename updates alias index without touching state file
- List returns both new-layout and legacy-layout sessions
- Atomic write: kill the process mid-write (simulated by injected failure) and verify no torn YAML
-
-These tests use `tempfile::TempDir` so they don't touch the real config directory.
-
-**Verification:** Unit tests pass. `cargo check` clean.
-
-### Step 3: Add `SessionHandle` and integrate with `RequestContext`
-
-Change `RequestContext.session` from `Option<Session>` to `Option<SessionHandle>`. This is a mass rename across the codebase — every callsite that does `ctx.session.as_ref()` needs to become `ctx.session.as_ref().map(|h| h.lock().await.get())` or similar.
-
-The cleanest way to minimize the blast radius is to add a thin compatibility layer on `RequestContext`:
-
-```rust
-impl RequestContext {
-    pub async fn session_read<F, R>(&self, f: F) -> Option<R>
-    where F: FnOnce(&Session) -> R {
-        let handle = self.session.as_ref()?;
-        let guard = handle.lock().await;
-        Some(f(guard.get()))
-    }
-
-    pub async fn session_write<F, R>(&mut self, f: F) -> Option<R>
-    where F: FnOnce(&mut Session) -> R {
-        let handle = self.session.as_ref()?;
-        let mut guard = handle.lock().await;
-        Some(f(guard.get_mut()))
-    }
-}
-```
-
-Most callsites become `ctx.session_read(|s| s.model_id.clone()).await` or `ctx.session_write(|s| s.add_message(...)).await`. A few that need to hold the guard across await points (e.g., compression) use `handle.lock()` directly.
-
-**Verification:** `cargo check` clean. Existing REPL functions still work because the old method names get forwarded through the compatibility helpers.
-
-### Step 4: Rewrite the 13 session callsites to use the store
-
-Go through each callsite in the inventory table and rewrite it:
-
-1. `Config::use_session` → `Engine::dispatch_command` for `CoreCommand::UseSession`
-2. `Config::use_session_safely` → same, with extra ctx reset logic
-3. `Config::exit_session` → `Engine::dispatch_command` for `CoreCommand::ExitSession`
-4. ... and so on
-
-Where possible, move the logic INTO `Engine::dispatch_command` rather than leaving it on `Config`. This is consistent with Phase 2's direction — core logic lives in the engine, not on state containers.
-
-For each rewrite:
- Delete the old method from `Config`
- Add the new handler in `Engine::dispatch_command`
- Update any callers that still reference the old method name
- Run `cargo check` after each file to catch issues incrementally
-
-**Verification:** After each rewrite, `cargo check` + the relevant integration tests from Phase 2. The Phase 2 `CollectingEmitter` tests for session-touching scenarios are especially important here — they're the regression net.
-
-### Step 5: Remove the compatibility helpers from `RequestContext`
-
-Once all 13 callsites are rewritten, the `session_read` / `session_write` helpers are only used by the old session methods we just deleted. Remove them. Any remaining compile errors point at callsites we missed.
-
-**Verification:** `cargo check` clean, all of Phase 2's tests still pass, plus the new `FileSessionStore` unit tests.
-
-### Step 6: Add the integration tests for concurrent access
-
-These are the tests that prove Phase 3 actually solved the concurrency problem:
-
-```rust
-#[tokio::test]
-async fn concurrent_opens_share_one_mutex() {
-    let store = FileSessionStore::new(tempdir);
-    let id = SessionId::new();
-    // ... create initial session ...
-
-    let h1 = store.open(None, id).await.unwrap();
-    let h2 = store.open(None, id).await.unwrap();
-
-    // Both handles should point at the same Arc<Mutex<Session>>
-    let lock1 = h1.lock().await;
-    // Try to lock h2 — should block
-    let try_lock = tokio::time::timeout(
-        Duration::from_millis(50),
-        h2.lock(),
-    ).await;
-    assert!(try_lock.is_err(), "h2 should block while h1 holds the lock");
-    drop(lock1);
-    let _lock2 = h2.lock().await;
-}
-
-#[tokio::test]
-async fn concurrent_writes_serialize_without_loss() {
-    let store = Arc::new(FileSessionStore::new(tempdir));
-    let id = create_initial_session(&store).await;
-
-    let tasks: Vec<_> = (0..100).map(|i| {
-        let store = store.clone();
-        tokio::spawn(async move {
-            let handle = store.open(None, id).await.unwrap();
-            {
-                let mut guard = handle.lock().await;
-                guard.get_mut().add_message(
-                    Input::from_str(format!("msg-{i}")),
-                    format!("reply-{i}"),
-                );
-            }
-            handle.save().await.unwrap();
-        })
-    }).collect();
-
-    for t in tasks { t.await.unwrap(); }
-
-    let handle = store.open(None, id).await.unwrap();
-    let guard = handle.lock().await;
-    assert_eq!(guard.get().messages.len(), 200);  // 100 user + 100 assistant
-}
-```
-
-The second test specifically verifies that the per-session mutex serialization prevents lost updates — the flaw in today's code.
-
-**Verification:** Both tests pass. `cargo test` green overall.
-
-### Step 7: Legacy migration smoke test
-
-Copy a real user's `sessions/my-project.yaml` file into a test fixture directory. Run `FileSessionStore::open_or_create_by_alias("my-project")` and assert:
-
- A new `by-id/<uuid>/state.yaml` exists with identical content
- A new `by-name/my-project` file exists containing the UUID
- The original `sessions/my-project.yaml` is still there, untouched
- A second `open_or_create_by_alias("my-project")` call reuses the same UUID (idempotent)
-
-**Verification:** Test passes with real fixture data including a session that has compressed messages and agent variables.
-
-### Step 8: Manual smoke test
-
-Run through a full REPL session covering every session-touching command:
-
-1. `loki` → REPL starts, `.session foo` → new session created, check `by-id/` and `by-name/foo` exist
-2. Several messages → check `state.yaml` updates atomically
-3. `.save session bar` → check alias renamed, UUID unchanged
-4. `.empty session` → messages cleared, file still exists
-5. `.exit session` → session closed
-6. `loki --session bar` from command line → same UUID resumes
-7. `.delete` then choose session → both new and legacy files gone
-8. Agent with `.agent sisyphus my-work` → agent-scoped session in `agents/sisyphus/sessions/`
-9. Auto-continuation in an agent → compression fires, concurrent writes serialize cleanly
-
-Every interaction should behave identically to pre-Phase-3.
-
---
-
-## Risks and Watch Items
-
-| Risk | Severity | Mitigation |
-|---|---|---|
-| **Legacy file discovery** | Medium | The migration path must handle every legacy layout: `sessions/<name>.yaml`, `sessions/_/<timestamp>-<autoname>.yaml`, and agent-scoped `agents/<agent>/sessions/<name>.yaml`. Write a fixture test for each variant. |
-| **Alias collisions during migration** | Medium | If two processes simultaneously migrate the same legacy session, they could create two different UUIDs. Mitigation: the `open_or_create_by_alias` path should acquire a file lock on the alias file itself during creation, not just rely on the store's in-memory map. |
-| **`RequestContext.session` type change blast radius** | Medium | Using the compatibility helpers (`session_read` / `session_write`) in Step 3 contains the blast radius. Only remove them in Step 5 once everything compiles. |
-| **Session::save deadlock via re-entry** | Medium | If `Session::compress()` or `add_message()` internally trigger anything that tries to re-lock the session's mutex, we get a deadlock. Audit every `Session` method called inside a `guard.get_mut()` scope to make sure none of them take the lock again. Document the invariant in `SessionHandle` rustdoc. |
-| **Tempfile cleanup on crash** | Low | If the process dies after writing `.yaml.tmp` but before the rename, we leave a stray file. On startup, `FileSessionStore::new` should sweep `by-id/*/state.yaml.tmp` files and remove them. |
-| **Alias index corruption** | Low | If `by-name/foo` contains garbage (not a valid UUID), treat it as a missing alias and log a warning. Don't crash the process. |
-| **Serde compatibility with old files** | Low | The `Session` struct's serde shape doesn't change in Phase 3, so old YAML files deserialize identically. Verify with a fixture test that includes every optional field set. |
-| **CLI `--session <uuid>` vs `--session <alias>` ambiguity** | Low | `SessionId::parse` recognizes UUID format; fall back to treating the argument as an alias if parsing fails. Document in `--help`. |
-| **Concurrent delete while handle held** | Low | If one task is using a handle while another deletes the session, the first task's save will fail (file missing). This is acceptable behavior — log a warning and return `StoreError::NotFound`. Tests should cover this. |
-

-
-## What Phase 3 Does NOT Do
-
- **No schema migration.** YAML format stays identical. `Session` struct unchanged.
- **No database.** `FileSessionStore` is the only implementation.
- **No session TTL / eviction.** Sessions live until explicitly deleted.
- **No cross-process locking.** Two Loki processes can still race, but writes are atomic so files never corrupt.
- **No session encryption.** Vault handles secrets; sessions are plain YAML.
- **No session sharing between users.** Each process has its own config directory.
- **No optimistic concurrency (mtime check).** Deferred to Phase 5+ as a UX enhancement.
- **No session versioning / rollback.** Deferred.
- **No changes to `Session::build_messages()`, compression logic, or autoname generation.** The behaviors that read/mutate `Session` stay the same — only how they're reached changes.
-
-The sole goal of Phase 3 is: **route all session persistence through a `SessionStore` trait with UUID-primary identity, lazy migration from the legacy layout, per-session mutex serialization, and atomic writes.**

-## Entry Criteria (from Phase 2)
-
- [ ] `Engine::run` is the only path to the LLM pipeline
- [ ] `CoreCommand::UseSession`, `ExitSession`, `EmptySession`, `CompressSession`, `SaveSession`, `EditSession` are all implemented and tested
- [ ] `CollectingEmitter` integration tests cover session-touching scenarios
- [ ] `cargo check`, `cargo test`, `cargo clippy` all clean
- [ ] CLI and REPL manual smoke tests match pre-Phase-2 behavior
-
-## Exit Criteria (Phase 3 complete)
-
- [ ] `src/session/` module exists with `SessionStore` trait, `FileSessionStore`, `SessionId`, `SessionAlias`, `SessionHandle`, `SessionGuard`
- [ ] `AppState.sessions: Arc<dyn SessionStore>` is wired in
- [ ] `RequestContext.session: Option<SessionHandle>` (not `Option<Session>`)
- [ ] All 13 session callsites go through the store; no direct `Session::load` or `Session::save` calls remain outside `FileSessionStore`
- [ ] Legacy layout files are lazily migrated on first access
- [ ] New layout (`by-id/<uuid>/state.yaml` + `by-name/<alias>`) is the canonical on-disk format for all new sessions

-# Phase 4 Implementation Plan: REST API Server
-
-## Overview
-
-Phase 4 introduces a `--serve` mode that starts an HTTP server exposing Loki's functionality as a RESTful API. The server is a thin axum layer on top of `Engine::run()` — most of the work is mapping HTTP requests into `RunRequest`s, mapping `Emitter` events into JSON or Server-Sent Events, and providing baseline auth, cancellation, and graceful shutdown. By the end of this phase, Loki can run as a backend service that multiple clients can talk to simultaneously, each with their own session.
-
-**Estimated effort:** ~1–2 weeks
-**Risk:** Low–medium. The core pipeline (Engine) is unchanged; the risk is in the HTTP layer's correctness around streaming, cancellation, and concurrent session handling.
-**Depends on:** Phases 1–3 complete. `SessionStore` with UUID identity, `Engine::run()` as the pipeline entrypoint, `Emitter` trait with working `TerminalEmitter` + `CollectingEmitter`.
-
---
-
-## Why Phase 4 Exists
-
-After Phase 3, everything the API server needs is already in place:
- `AppState` is a clonable `Arc` holding global services, safe to share across concurrent HTTP handlers.
- `RequestContext` is per-request mutable state with no hidden global singletons.
- `Engine::run()` is the single pipeline entrypoint that works for any frontend.
- `SessionStore` serves sessions by UUID with per-session mutex serialization.
- `Emitter` trait decouples output from destination.
-
-What's missing is the last mile: accepting HTTP requests, routing them to `Engine::run()`, and turning `Event`s into HTTP responses. This phase builds exactly that.
-
-The mental model is "Loki as a backend service." A frontend developer should be able to `curl -X POST http://localhost:3400/v1/completions -d '{"prompt":"hello"}'` and get a sensible response. A JavaScript app should be able to open an EventSource to `/v1/sessions/:id/completions?stream=true` and get live token streaming. An automation script should be able to maintain session state across many requests by passing back the same session UUID.

-### Request/response shapes
-
-**One-shot completion:**
-
-```

-```
-
-**Non-streaming response (default):**
-
-```json

-  "session_id": null,
-  "final_message": "The TCP handshake is a three-way protocol ...",
-  "tool_calls": [

-
-**Create session:**
-
-```
-POST /v1/sessions

-
-**Session completion:**
-
-```
-POST /v1/sessions/550e8400-.../completions
-
-{
-  "prompt": "what was the bug we found yesterday?",
-  "stream": true,
-  "auto_continue": true
-}
-```
-
-Returns the same shape as `/v1/completions`, but with `session_id` populated and agent runtime state preserved across calls.
-
-**Error responses** (standard across all endpoints):
-
-```json
-{
-  "error": {
-    "code": "session_not_found",
-    "message": "No session with id 550e8400-...",
-    "request_id": "7a1b..."
-  }
-}
-```
-
-HTTP status codes map from `CoreError::http_status()` (defined in Phase 2):
- `InvalidRequest` → 400
- `Unauthorized` → 401
- `NotFound` → 404
- `InvalidState` → 409 (expected state doesn't match)
- `Cancelled` → 499 (client-closed request, borrowed from nginx)
- `ProviderError` → 502 (upstream LLM failed)
- `ToolError` → 500
- `Other` → 500
-

-## Core Types
-
-### `ApiConfig`
-
-```rust
-#[derive(Clone, Deserialize)]
-pub struct ApiConfig {
-    pub enabled: bool,
-    pub listen_addr: SocketAddr,
-    pub auth: AuthConfig,
-    pub cors: CorsConfig,
-    pub limits: LimitsConfig,
-    pub request_timeout_seconds: u64,
-    pub shutdown_grace_seconds: u64,
-}
-
-#[derive(Clone, Deserialize)]
-pub enum AuthConfig {
-    Disabled,                                      // dev only
-    StaticKeys { keys: Vec<AuthKeyEntry> },        // simple key list
-    // future: JwtIssuer { ... }, OAuthIntrospect { ... }
-}
-
-#[derive(Clone, Deserialize)]
-pub struct AuthKeyEntry {
-    pub subject: String,                           // for logs
-    pub key_hash: String,                          // bcrypt or argon2 hash
-    pub scopes: Vec<String>,
-}
-
-#[derive(Clone, Deserialize)]
-pub struct CorsConfig {
-    pub allowed_origins: Vec<String>,              // empty = no CORS
-    pub allow_credentials: bool,
-}
-
-#[derive(Clone, Deserialize)]
-pub struct LimitsConfig {
-    pub max_body_bytes: usize,                     // request body limit
-    pub max_concurrent_requests: usize,            // semaphore
-    pub rate_limit_per_minute: Option<usize>,      // optional per-subject
-}
-```
-
-`ApiConfig` loads from `config.yaml` under a new top-level `api:` block. It's NOT part of `AppConfig` because it only matters in `--serve` mode; in CLI/REPL mode it's ignored.
-
-```yaml
-# config.yaml
-api:
-  enabled: false                        # false = --serve refuses to start without explicit enable
-  listen_addr: "127.0.0.1:3400"
-  auth:
-    mode: StaticKeys
-    keys:
-      - subject: "alice"
-        key_hash: "$argon2id$..."
-        scopes: ["read", "write"]
-  cors:
-    allowed_origins: []
-    allow_credentials: false
-  limits:
-    max_body_bytes: 1048576             # 1 MiB
-    max_concurrent_requests: 64
-    rate_limit_per_minute: null
-  request_timeout_seconds: 300          # 5 minutes default
-  shutdown_grace_seconds: 30
-```
-
-### `ApiState`
-
-```rust
-#[derive(Clone)]
-pub struct ApiState {
-    pub app: Arc<AppState>,
-    pub engine: Arc<Engine>,
-    pub config: Arc<ApiConfig>,
-    pub request_counter: Arc<AtomicU64>,
-    pub active_requests: Arc<Semaphore>,
-}
-```
-
-`ApiState` is the axum-friendly wrapper that every handler receives via the `State` extractor. It's clonable (cheap — all fields are `Arc` or atomic) and thread-safe. Handlers get a clone per request.
-
-### `JsonEmitter`
-
-Phase 2 promised `JsonEmitter` and `SseEmitter` as deferred deliverables. Phase 4 implements them.
-
-```rust
-pub struct JsonEmitter {
-    events: Mutex<Vec<OwnedEvent>>,
-    tool_calls: Mutex<Vec<ToolCallRecord>>,
-    final_message: Mutex<Option<String>>,
-    outcome: Mutex<Option<RunOutcome>>,
-}
-
-impl JsonEmitter {
-    pub fn new() -> Self { /* ... */ }
-
-    /// Consume the emitter and return the JSON response body.
-    pub fn into_response(self) -> serde_json::Value { /* ... */ }
-}
-
-#[async_trait]
-impl Emitter for JsonEmitter {

-    }

-
-The non-streaming HTTP handler creates a `JsonEmitter`, calls `Engine::run`, and then calls `.into_response()` to get the final JSON body.
-
-### `SseEmitter`

-```
-
-The streaming handler creates an mpsc channel, hands the sender half to an `SseEmitter`, and returns an `axum::response::sse::Sse` wrapping the receiver half. axum streams each event as it's emitted, with automatic flushing. If the client disconnects, the send fails, `client_disconnected` is set, and subsequent emits return `ClientDisconnected` — which the engine respects by continuing to completion without emitting further (Phase 2 designed this behavior in).
-
---
-
-## Middleware Stack
-
-The axum router wraps handlers in a layered middleware stack. Order matters because middleware is applied outside-in on requests, inside-out on responses.
-
-```rust
-let router = Router::new()
-    .route("/v1/auth/check", post(handlers::auth_check))
-    .route("/v1/models", get(handlers::list_models))
-    .route("/v1/agents", get(handlers::list_agents))
-    .route("/v1/roles", get(handlers::list_roles))
-    .route("/v1/rags", get(handlers::list_rags))
-    .route("/v1/info", get(handlers::info))
-    .route("/v1/completions", post(handlers::one_shot_completion))
-    .route("/v1/sessions", post(handlers::create_session).get(handlers::list_sessions))
-    .route("/v1/sessions/:id", get(handlers::get_session).delete(handlers::delete_session))
-    .route("/v1/sessions/:id/completions", post(handlers::session_completion))
-    .route("/v1/sessions/:id/compress", post(handlers::compress_session))
-    .route("/v1/sessions/:id/empty", post(handlers::empty_session))
-    .route("/v1/sessions/:id/role", post(handlers::set_role).delete(handlers::clear_role))
-    .route("/v1/sessions/:id/agent", post(handlers::set_agent).delete(handlers::clear_agent))
-    .route("/v1/sessions/:id/rag", post(handlers::set_rag).delete(handlers::clear_rag))
-    .route("/v1/rags/:name/rebuild", post(handlers::rebuild_rag))
-    .layer(middleware::from_fn_with_state(state.clone(), middleware::auth))
-    .layer(middleware::from_fn(middleware::request_id))
-    .layer(middleware::from_fn_with_state(state.clone(), middleware::concurrency_limit))
-    .layer(middleware::from_fn(middleware::tracing))
-    .layer(middleware::from_fn(middleware::error_handler))
-    .layer(tower_http::timeout::TimeoutLayer::new(Duration::from_secs(
-        state.config.request_timeout_seconds,
-    )))
-    .layer(tower_http::limit::RequestBodyLimitLayer::new(state.config.limits.max_body_bytes))
-    .layer(cors_layer(&state.config.cors))
-    .with_state(state);
-```
-
-### Middleware responsibilities
-
-**auth** — Validates `Authorization: Bearer <key>` header against the configured auth provider. Compares against stored hashes (bcrypt/argon2), never plaintext. On success, attaches an `AuthContext { subject, scopes }` to request extensions. On failure, returns 401 immediately without calling the handler. If `AuthConfig::Disabled`, synthesizes an `AuthContext { subject: "anonymous", scopes: vec!["*"] }` for local dev.
-
-**request_id** — Generates a UUID request ID, attaches it to request extensions for downstream correlation, emits it as `X-Request-Id` in the response headers. Used by tracing and error handlers.
-
-**concurrency_limit** — Acquires a permit from `state.active_requests` semaphore with a short timeout. If the server is saturated, returns 503 Service Unavailable immediately. This protects against runaway connection counts exhausting resources.
-
-**tracing** — Wraps the request in a `tracing::Span` carrying the request ID, subject, method, path, and session ID if present. Every log line and every tool call emitted during the request carries this span context. Essential for debugging production issues.
-
-**error_handler** — Catches `CoreError` from handler results and maps to proper HTTP responses using `CoreError::http_status()` and a JSON error body. Ensures no handler leaks an `anyhow::Error` or raw `?` into an axum 500.
-
-**timeout** — Overall request deadline. After N seconds (default 300), the request is aborted. This is a backstop — the engine's per-request cancellation token is the primary cancellation mechanism.
-
-**body limit** — Rejects requests larger than the configured max. Default 1 MiB is enough for prompts with several files attached; adjustable in config.
-
-**cors** — Attaches `Access-Control-Allow-Origin` headers for cross-origin browsers. Empty allowed origins = no CORS headers emitted (safe default). `allow_credentials: true` enables cookie/auth forwarding.
-
-### What's NOT in middleware
-
- **Rate limiting per subject** — deferred. The `rate_limit_per_minute` config option is wired through but the middleware is a stub in Phase 4. Real rate limiting with sliding windows lands in a follow-up.
- **Request/response logging** — use the tracing middleware's output; don't add a separate HTTP log layer.
- **Metrics** — deferred to Phase 4.5 (Prometheus endpoint). Phase 4 just exposes counters in `ApiState`.
- **Content negotiation** — Phase 4 assumes JSON requests. `Accept: text/event-stream` is the only alternate content type we handle, and only on completion endpoints.
-

-
-## Handler Pattern
-
-Every handler follows the same shape:
-
-```rust
-pub async fn session_completion(
-    State(state): State<ApiState>,
-    Extension(auth): Extension<AuthContext>,
-    Extension(request_id): Extension<Uuid>,
-    Path(session_id): Path<String>,
-    Json(req): Json<CompletionRequest>,
-) -> Result<Response, ApiError> {
-    // 1. Parse domain types
-    let session_id = SessionId::parse(&session_id)
-        .map_err(|_| ApiError::bad_request("invalid session id"))?;
-
-    // 2. Open the session handle
-    let handle = state.app.sessions.open(None, session_id).await
-        .map_err(|e| match e {
-            StoreError::NotFound { .. } => ApiError::not_found("session", &session_id.to_string()),
-            other => ApiError::from(other),
-        })?;
-
-    // 3. Build RequestContext from AppState + session
-    let mut ctx = RequestContext::new(state.app.clone(), WorkingMode::Api);
-    ctx.session = Some(handle);
-    ctx.auth = Some(auth);
-
-    // 4. Build cancellation token that fires on client disconnect
-    let cancel = CancellationToken::new();
-
-    // 5. Convert the HTTP request to a RunRequest
-    let run_req = RunRequest {
-        input: Some(UserInput::from_api(req.prompt, req.files)?),
-        command: None,
-        options: {
-            let mut o = if req.session_active {
-                RunOptions::api_session()
-            } else {
-                RunOptions::api_oneshot()
-            };
-            o.stream = req.stream;
-            o.auto_continue = req.auto_continue.unwrap_or(false);
-            o.cancel = cancel.clone();
-            o
-        },
-    };
-
-    // 6. Branch on streaming vs JSON
-    if req.stream {
-        // Create SseEmitter + channel, spawn engine task, return Sse response
-        let (tx, rx) = mpsc::channel(32);
-        let emitter = SseEmitter::new(tx);
-        let engine = state.engine.clone();
-
-        tokio::spawn(async move {
-            let _ = engine.run(&mut ctx, run_req, &emitter).await;
-            // Emitter Drop closes the channel; Sse stream ends naturally
-        });
-
-        Ok(Sse::new(ReceiverStream::new(rx))
-            .keep_alive(KeepAlive::default())
-            .into_response())
-    } else {
-        // Use JsonEmitter synchronously, return JSON body
-        let emitter = JsonEmitter::new();
-        state.engine.run(&mut ctx, run_req, &emitter).await
-            .map_err(ApiError::from)?;
-        Ok(Json(emitter.into_response()).into_response())
-    }
-}
-```
-
-The streaming path spawns a background task because axum needs to return the `Response` (with the SSE stream) before the engine finishes its work. The task owns the `ctx` and `emitter`, runs to completion, and naturally terminates when the engine returns. The channel closing signals the end of the stream to axum.
-
-The non-streaming path runs synchronously in the handler task because we need the full result before returning the response body.
-
---
-
-## Cancellation and Client Disconnect
-
-Two cancellation sources, one unified mechanism:
-
-1. **Client disconnect during streaming.** axum signals this by dropping the SSE receiver. The next `SseEmitter::emit` call fails with `ClientDisconnected`, which the engine handles by stopping further emits but continuing to completion so session state is persisted correctly.
-
-2. **Request timeout.** The outer tower timeout layer fires after N seconds, dropping the handler's future. This cancels any pending awaits in the engine, which propagates through tokio cancellation. Active tool calls (especially bash/python/typescript subprocesses) need to be killed cleanly — this is the same concern as Phase 2's Ctrl-C handling.
-
-The engine's `CancellationToken` handles both cases uniformly. For streaming, the handler watches the SSE sender's `closed()` signal and triggers `cancel.cancel()` when the client goes away. For timeout, tower's dropped future causes the handler task to be aborted, which drops `cancel` and fires any `cancelled()` waiters in the engine.
-
-```rust
-// Inside the streaming handler:
-let cancel_for_disconnect = cancel.clone();
-let send_tx = tx.clone();
-tokio::spawn(async move {
-    send_tx.closed().await;  // resolves when receiver drops
-    cancel_for_disconnect.cancel();
-});
-```
-
-**Tool call cancellation** is the interesting case. A running bash/python/typescript subprocess must be killed when `cancel` fires. The existing tool execution code uses `AbortSignal` from the `abort_on_ctrlc` crate; Phase 2's shim layer adapts it to `CancellationToken`. Phase 4 doesn't need to change this — it just needs to verify that the adapter is still firing correctly when cancellation comes from HTTP disconnect instead of Ctrl-C.
-
---
-
-## Per-Request State Isolation
-
-The critical correctness property: **two concurrent requests must not share mutable state.** The architecture from Phases 1–3 makes this structural rather than something we have to police:
-
- `AppState` is `Arc`-wrapped and contains only immutable config and shared services (vault, RAG cache, MCP factory, session store).
- `RequestContext` is constructed fresh in each handler — two requests get two independent contexts.
- `SessionHandle` uses per-session `Mutex` serialization — two concurrent requests on the *same* session wait their turn (by design).
- `McpFactory` acquires handles via per-key sharing — two requests using the same MCP server share one process; two using different servers get independent processes.
- `RagCache` shares `Arc<Rag>` via weak refs — same sharing property.
-
-The one place where the architecture can't help us is **agent runtime isolation**. Two concurrent API requests on two different sessions, both running agents, must get two fully independent `AgentRuntime`s with their own supervisors, inboxes, todo lists, and escalation queues. Phase 1 Step 6.5 made this work by putting `AgentRuntime` on `RequestContext`, which is already per-request. Phase 4 just needs to verify nothing regresses.
-
-**Integration test for this:** spin up 10 concurrent requests, each running a different agent with tools, and assert that each one gets its own tool call history, its own todo list, and its own eventual response. Use a mock LLM so the test is deterministic.
-

-
-## Migration Strategy
-
-### Step 1: Add dependencies and scaffolding
-
-Add to `Cargo.toml`:
-
-```toml
-axum = { version = "0.8", features = ["macros"] }
-tower = "0.5"
-tower-http = { version = "0.6", features = ["cors", "limit", "timeout", "trace"] }
-argon2 = "0.5"
-```
-
-`hyper` is already present. `tokio-stream` for SSE.
-
-Create module structure:
-
- `src/api/mod.rs` — module root, `serve()` entrypoint
- `src/api/config.rs` — `ApiConfig`, `AuthConfig`, etc.
- `src/api/state.rs` — `ApiState`
- `src/api/auth.rs` — middleware + `AuthContext`
- `src/api/middleware.rs` — other middlewares (request_id, tracing, concurrency_limit, error_handler)
- `src/api/error.rs` — `ApiError` + conversion from `CoreError`
- `src/api/emitters/json.rs` — `JsonEmitter`
- `src/api/emitters/sse.rs` — `SseEmitter`
- `src/api/handlers/mod.rs` — handler module root
- `src/api/handlers/completions.rs` — one-shot and session completions
- `src/api/handlers/sessions.rs` — session CRUD
- `src/api/handlers/metadata.rs` — list models/agents/roles/rags
- `src/api/handlers/scope.rs` — role/agent/rag attachment endpoints
- `src/api/handlers/rag.rs` — rebuild endpoint
-
-Register `pub mod api;` in `src/main.rs`. Add a `--serve` CLI flag that calls `api::serve(app_state).await`.
-
-**Verification:** `cargo check` clean with empty handler stubs returning 501 Not Implemented.
-
-### Step 2: Implement auth middleware and error handling
-
-Build the auth middleware against `AuthConfig::StaticKeys` using argon2 for verification. Implement `ApiError` with `IntoResponse` that produces the JSON error body. Implement `From<CoreError>` for `ApiError` using `CoreError::http_status()` and `CoreError::message()` (add those methods to `CoreError` in Phase 2 if they don't exist yet; otherwise add here).
-
-Write unit tests:
- Valid key → handler runs, `AuthContext` is attached
- Invalid key → 401
- Missing key → 401
- `AuthConfig::Disabled` → anonymous context synthesized
-
-**Verification:** Auth tests pass. `curl -H "Authorization: Bearer <valid-key>" http://localhost:3400/v1/info` returns info; without the header returns 401.
-
-### Step 3: Implement `JsonEmitter` and `SseEmitter`
-
-Both are relatively mechanical. `JsonEmitter` accumulates events into a buffer and exposes `into_response()`. `SseEmitter` converts each event to an axum SSE frame and pushes into an mpsc channel.
-
-Write unit tests using `NullEmitter` → feed a scripted sequence of events → assert the resulting JSON or SSE frames.
-
-**Verification:** Both emitters have unit tests that drive a scripted `Event` sequence and compare to golden outputs.
-
-### Step 4: Implement metadata handlers
-
-Start with the easy endpoints: `GET /v1/models`, `/v1/agents`, `/v1/roles`, `/v1/rags`, `/v1/info`. These don't call the engine — they just read from `AppState` and return JSON.
-
-**Verification:** `curl` each endpoint and inspect output. Write integration tests that spin up the router and hit each endpoint.
-
-### Step 5: Implement session CRUD handlers
-
-`POST /v1/sessions` creates via `SessionStore::create`. `GET /v1/sessions` lists via `SessionStore::list`. `GET /v1/sessions/:id` reads metadata + message history via `SessionStore::open` + handle lock. `DELETE /v1/sessions/:id` calls `SessionStore::delete`.
-
-These handlers don't call the engine either. They're thin wrappers around `SessionStore`.
-
-**Verification:** Create a session via POST, list it, read it, delete it, confirm 404 after delete. All through `curl`.
-
-### Step 6: Implement one-shot completion handler
-
-`POST /v1/completions` is the first engine-calling handler. It constructs a fresh `RequestContext` with no session, builds a `RunRequest` from the HTTP body, and calls `Engine::run` with either `JsonEmitter` or `SseEmitter` based on the `stream` flag.
-
-This is where the streaming infrastructure first gets exercised end-to-end. Test both modes:
-
-```bash
-# Non-streaming
-curl -X POST http://localhost:3400/v1/completions \
-  -H "Authorization: Bearer <key>" \
-  -H "Content-Type: application/json" \
-  -d '{"prompt":"hello"}'
-
-# Streaming
-curl -N -X POST http://localhost:3400/v1/completions \
-  -H "Authorization: Bearer <key>" \
-  -H "Content-Type: application/json" \
-  -H "Accept: text/event-stream" \
-  -d '{"prompt":"hello","stream":true}'
-```
-
-**Verification:** Both modes work with a real LLM. Disconnect the streaming client mid-response (Ctrl-C on curl) and verify the engine task gets cancelled cleanly — no orphaned MCP subprocesses, no hung tool executions.
-
-### Step 7: Implement session completion handler
-
-`POST /v1/sessions/:id/completions` is the same as one-shot but with a session attached. The handler calls `store.open(id)`, builds a context with `ctx.session = Some(handle)`, and proceeds as before. Session state is automatically persisted by the engine at the end of the turn.
-
-Concurrent request test: spin up 10 concurrent `curl` commands all hitting the same session. Assert:
- All 10 complete successfully
- The session has 10 message pairs appended in some order (serialized by the per-session mutex)
- No lost updates, no corrupted YAML
-
-**Verification:** Concurrent test passes reliably. Run it 100 times in a loop to catch races.
-
-### Step 8: Implement scope attachment handlers
-
-`POST /v1/sessions/:id/role`, `/agent`, `/rag` and their `DELETE` counterparts. Each one opens the session handle, constructs a `RunRequest` with a `CoreCommand` variant (`UseRole`, `UseAgent`, `UseRag`), and calls the engine with no input — just the command. The engine dispatches the command, mutates state, and the session is persisted.
-
-**Verification:** `POST /v1/sessions/<id>/role {"name":"explain"}` activates the role. Subsequent completion on the session uses the role. `DELETE /v1/sessions/<id>/role` clears it.
-
-### Step 9: Implement miscellaneous handlers
-
-`POST /v1/sessions/:id/compress`, `/empty`, `POST /v1/rags/:name/rebuild`. Same pattern: translate to `CoreCommand` and dispatch.
-
-**Verification:** All endpoints respond correctly.
-
-### Step 10: Graceful shutdown
-
-axum's graceful shutdown requires a signal future. Wire it up:
-
-```rust
-pub async fn serve(app: Arc<AppState>, config: ApiConfig) -> Result<()> {
-    let state = ApiState::new(app, config);
-    let router = build_router(state.clone());
-    let listener = tokio::net::TcpListener::bind(state.config.listen_addr).await?;
-
-    let shutdown_signal = async {
-        tokio::signal::ctrl_c().await.ok();
-        info!("Received shutdown signal, draining requests...");
-    };
-
-    axum::serve(listener, router)
-        .with_graceful_shutdown(shutdown_signal)
-        .await?;
-
-    info!("Draining active sessions...");
-    tokio::time::timeout(
-        Duration::from_secs(state.config.shutdown_grace_seconds),
-        drain_active_requests(&state),
-    ).await.ok();
-
-    info!("Shutdown complete.");
-    Ok(())
-}
-```
-
-`drain_active_requests` waits for the semaphore to return to full capacity, bounded by `shutdown_grace_seconds`. After the grace period, any remaining requests are force-cancelled.
-
-**Verification:** Start server, send a long streaming request, hit Ctrl-C. The server should finish the in-flight request (up to the grace period) before exiting, not cut it off mid-stream.
-
-### Step 11: Configuration loading and docs
-
-Wire `ApiConfig` through `config.yaml` parsing. Add a default `api.enabled: false` so the server refuses to start without explicit opt-in. Document the config shape, endpoint schemas, and auth setup in `docs/REST-API-SERVER.md`.
-
-**Verification:** Start with `api.enabled: false` → fatal error with helpful message. Start with `api.enabled: true` + no auth keys → fatal error demanding at least one key (unless `AuthConfig::Disabled` is explicit).
-
-### Step 12: Integration test suite
-
-Write a comprehensive integration test suite in `tests/api/` that exercises the full HTTP surface with a mock LLM:
-
- Auth: valid, invalid, missing, disabled
- Metadata: list each resource type
- Session lifecycle: create → list → read → delete
- One-shot completion: JSON + SSE
- Session completion: single + concurrent
- Scope attachment: role, agent, rag (set + clear)
- Cancellation: client disconnect mid-stream, timeout expiry
- Graceful shutdown: in-flight requests complete within grace period
- Concurrent sessions: 20 sessions, each with a few turns, all running at once
-
-Use `reqwest` as the test client. Spin up the server on a random port per test. The mock LLM lives as a fake `Client` implementation that returns scripted responses.
-
-**Verification:** All tests pass. CI runs them on every PR.

-## Risks and Watch Items
-
-| Risk | Severity | Mitigation |
-|---|---|---|
-| **SSE client disconnect detection lag** | High | The mpsc channel's `closed()` signal is the primary disconnect detector. Verify it fires within <1s of a real client disconnect. Add integration test with `reqwest` that opens a stream, sends a few events, drops the connection, and asserts the engine's cancellation token fires within 2s. |
-| **Concurrent session writes losing data** | High | Phase 3's per-session mutex handles this structurally. Verify with the 100-concurrent-writers integration test from Phase 3 adapted to hit the HTTP layer. |
-| **Orphaned tool subprocesses on timeout** | High | Tool execution must respect the cancellation token. Test: start a completion that triggers a bash tool running `sleep 60`, timeout at 5s, verify the `sleep` process is killed (not reparented to init). |
-| **Auth key storage** | High | Store argon2 hashes, never plaintext. Rotate via config reload (future). Log subject (not key) on every request. Audit: no `println!` of any part of the key anywhere. |
-| **Streaming body size growth** | Medium | A long session with many tool calls produces a lot of SSE frames. Verify the mpsc channel size (32) is enough; if not, backpressure causes the engine task to block on emit. Document in the emitter: `emit()` can await. |
-| **CORS misconfiguration** | Medium | Default to no CORS. Require explicit origin allowlist. Log warnings on wildcard usage. Browser-accessible deployments should use a reverse proxy to terminate CORS. |
-| **Auth bypass via malformed header** | Medium | Use axum's `Authorization` typed header extractor, not raw string parsing. Reject unknown schemes (only Bearer accepted). |
-| **Rate limit stub** | Low | Document that `rate_limit_per_minute` is not yet implemented. Add an issue for follow-up. Protect against DoS with `max_concurrent_requests` in the meantime. |
-| **Session metadata leak across users** | Low | `GET /v1/sessions` lists all sessions regardless of caller identity in Phase 4. Document this limitation: Phase 4's auth is coarse-grained (anyone with a valid key sees all sessions). Per-subject session ownership lands in a follow-up phase. Treat Phase 4 as single-tenant-per-key for now. |
-| **Body size abuse** | Low | `max_body_bytes` caps payload. File uploads (not yet supported) would need separate multipart handling. |
-| **Port binding failure** | Low | Fail fast with clear error if the configured port is in use or unreachable. Don't silently retry. |

- **No WebSocket support.** SSE is sufficient for server-to-client streaming; WebSockets would add bidirectional complexity we don't need. Client-to-server commands use regular HTTP POST.
- **No multi-tenancy.** All sessions are visible to any authenticated caller. Per-subject session ownership is a follow-up.
- **No rate limiting.** `rate_limit_per_minute` config exists but is a stub.
- **No metrics endpoint.** Counters are in memory; Prometheus scraping lands later.
- **No API versioning beyond `/v1/`.** Breaking changes would introduce `/v2/`.
- **No JWT or OAuth.** Static API keys only. JWT introspection can extend `AuthConfig` later.
- **No request signing.** Bearer tokens over HTTPS (users provide their own TLS termination via reverse proxy).
- **No admin endpoints.** Server management (reload config, view metrics, kill sessions) is not exposed.
- **No file upload.** File references in requests use absolute paths or URLs that the server fetches; no multipart uploads in Phase 4.
- **No MCP tool exposure over API.** The API calls the engine, which runs tools internally. Direct "execute this tool" API endpoints don't exist and are not planned.

-# Phase 5 Implementation Plan: Tool Scope Pooling and Lifecycle
-
-## Overview
-
-Phase 5 turns the trivial no-pool `McpFactory` from Phase 1 Step 6.5 into a production-grade pooling layer with idle timeouts, a background reaper, health checks, and graceful shutdown integration. The architecture doesn't change — `McpFactory::acquire()` is still the only entry point, `Arc<McpServerHandle>` is still the reference type — but the factory now aggressively shares MCP subprocesses across scopes to keep warm-path latency near zero.
-
-**Estimated effort:** ~1 week
-**Risk:** Medium. The pooling logic has subtle ordering concerns (handle Drop → idle pool vs teardown → reaper eviction). Get those wrong and you leak processes or double-free.
-**Depends on:** Phases 1–4 complete. Phase 4 is important because it's the first workload where pooling actually matters — CLI and REPL don't generate enough concurrent scope transitions to justify the complexity.
-
---
-
-## Why Phase 5 Exists
-
-After Phase 4 lands, the API server works correctly but has a performance problem: every API session activates its own MCP processes, and when the session closes, those processes tear down immediately. A realistic production workload — 20 concurrent users each sending a burst of requests — spawns and kills MCP subprocesses at an unsustainable rate. For servers like `github` that take 1–2 seconds to start (subprocess + stdio handshake + OAuth + `tools/list`), every API call adds visible cold-start latency.
-
-The architectural framing for the fix was already designed in Phase 1 Step 6.5 and Phase 1's "MCP Lifecycle Policy" section:
-
-1. **Layer 1: active Arc reference counting.** Already done in Phase 1. Scopes hold `Arc<McpServerHandle>`; the last drop triggers teardown.
-2. **Layer 2: idle grace period.** Not yet implemented. After the last Arc drops, the handle moves to an idle pool with a timestamp instead of tearing down. A background reaper evicts entries that have been idle past the configured threshold.
-3. **Acquisition order.** `acquire(key)` checks the active map first, then the idle pool (revival = zero latency), then spawns fresh.
-
-Phase 5 implements Layer 2 + the reaper + the revival logic + the health check + graceful shutdown integration. No changes to the caller API. No changes to any other phase's code.
-
-**This is a pure optimization phase.** Correctness is unchanged; only performance improves.

-## Core Types
-
-### `McpFactory` (expanded)
-
-```rust
-pub struct McpFactory {
-    active: Mutex<HashMap<McpServerKey, Weak<McpServerHandleInner>>>,
-    idle: Mutex<HashMap<McpServerKey, IdleEntry>>,
-    config: McpFactoryConfig,
-    shutdown: Arc<AtomicBool>,
-    reaper_handle: Mutex<Option<JoinHandle<()>>>,
-}
-
-struct IdleEntry {
-    handle: Arc<McpServerHandleInner>,
-    idle_since: Instant,
-    last_health_check: Option<Instant>,
-}
-
-pub struct McpFactoryConfig {
-    pub idle_timeout: Duration,
-    pub cleanup_interval: Duration,
-    pub max_idle_servers: Option<usize>,
-    pub health_check: Option<HealthCheckPolicy>,
-}
-
-pub struct HealthCheckPolicy {
-    pub interval: Duration,
-    pub timeout: Duration,
-    pub on_failure: HealthFailureAction,
-}
-
-pub enum HealthFailureAction {
-    Evict,
-    EvictAndLog,
-    LogOnly,
-}
-```
-
-The factory grows three new pieces of state compared to Phase 1's stub:
-
- **`idle` map** — stores handles that nobody currently owns but that we've decided to keep warm.
- **`shutdown` flag** — tells the reaper to exit and prevents new inserts into `idle` during drain.
- **`reaper_handle`** — the `JoinHandle` of the background task, awaited during graceful shutdown.
-
-### `McpServerHandle` (refined)
-
-Phase 1's `Arc<McpServerHandle>` becomes `Arc<McpServerHandleInner>`, and we add a `Drop` impl on the inner type that handles the "return to idle pool" logic:
-
-```rust
-pub struct McpServerHandleInner {
-    key: McpServerKey,
-    service: RwLock<RunningService<RoleClient, ()>>,
-    factory: Weak<McpFactory>,
-    spawned_at: Instant,
-    returning_to_pool: AtomicBool,
-}
-
-impl Drop for McpServerHandleInner {
-    fn drop(&mut self) {
-        // If we're already returning to pool (revived from idle),
-        // don't re-insert — the factory is handling it.
-        if self.returning_to_pool.load(Ordering::Acquire) {
-            return;
-        }
-
-        let Some(factory) = self.factory.upgrade() else {
-            // Factory is gone — just let the service die via its own drop.
-            return;
-        };
-
-        if factory.shutdown.load(Ordering::Acquire) {
-            // Shutting down — don't put it back in idle, just die.
-            return;
-        }
-
-        // Take ownership of self.service and move to idle pool.
-        // This requires unsafe or a different ownership structure — see
-        // "The Drop trick" section below.
-        factory.return_to_idle(self);
-    }
-}
-```
-
-**The Drop trick** — the issue is that `Drop::drop` can't actually move `self`'s fields out without `unsafe`, but we need to move the `RunningService` into the idle pool. The clean solution is to wrap the service in an `Option<RunningService>`:
-
-```rust
-pub struct McpServerHandleInner {
-    key: McpServerKey,
-    service: Mutex<Option<RunningService<RoleClient, ()>>>,  // Option so we can take() in Drop
-    factory: Weak<McpFactory>,
-    spawned_at: Instant,
-}
-
-impl Drop for McpServerHandleInner {
-    fn drop(&mut self) {
-        let Some(factory) = self.factory.upgrade() else { return; };
-        if factory.shutdown.load(Ordering::Acquire) { return; }
-
-        // Take the service out. After this, self.service is None.
-        let service = match self.service.get_mut().take() {
-            Some(s) => s,
-            None => return,  // Already taken — e.g., by shutdown drain.
-        };
-
-        // Spawn a task to move it into the idle pool (can't await in Drop).
-        let key = self.key.clone();
-        let factory = factory.clone();
-        tokio::spawn(async move {
-            factory.accept_returning_handle(key, service).await;
-        });
-    }
-}
-```
-
-This has the right shape but introduces a subtle race: the `tokio::spawn` inside `Drop` runs asynchronously, so if a new `acquire(key)` arrives between the Drop and the spawned task completing, it won't find the handle in `idle` yet and will spawn a fresh subprocess. That's acceptable — it's slightly wasteful but not incorrect, and the race window is microseconds.
-
-An alternative that avoids the race: use a dedicated `return_tx: mpsc::UnboundedSender<ReturningHandle>` on the factory, push synchronously into it from Drop, and a single "idle manager" task owns the idle map. This is cleaner because the idle map only mutates from one task, but it adds a coordination point. **Recommendation: start with the `tokio::spawn` approach; switch to the mpsc pattern only if the race causes visible issues.**
-
-### `McpServerHandle` (the public Arc wrapper)
-
-```rust
-pub struct McpServerHandle(Arc<McpServerHandleInner>);
-
-impl McpServerHandle {
-    pub async fn call_tool(&self, tool: &str, args: Value) -> Result<ToolResult> {
-        let guard = self.0.service.lock().await;
-        let service = guard.as_ref().ok_or(McpError::HandleDrained)?;
-        service.call_tool(tool, args).await
-    }
-
-    pub async fn list_tools(&self) -> Result<Vec<ToolSpec>> {
-        let guard = self.0.service.lock().await;
-        let service = guard.as_ref().ok_or(McpError::HandleDrained)?;
-        service.list_tools().await
-    }
-}
-
-impl Clone for McpServerHandle {
-    fn clone(&self) -> Self { Self(self.0.clone()) }
-}
-```
-
-Callers get a `McpServerHandle` (which is `Arc<Inner>` internally) from `acquire()`. Cloning is cheap. Dropping the last clone fires the `Drop` on `Inner`, which returns the underlying service to the idle pool or kills it.
-
---
-
-## The `acquire` Path
-
-Three cases in order:
-
-```rust
-impl McpFactory {
-    pub async fn acquire(&self, key: &McpServerKey) -> Result<McpServerHandle> {
-        // Case 1: Active share
-        {
-            let active = self.active.lock();
-            if let Some(weak) = active.get(key) {
-                if let Some(inner) = weak.upgrade() {
-                    metrics::mcp_acquire_hit_active();
-                    return Ok(McpServerHandle(inner));
-                }
-                // Weak is dangling; let it fall through.
-            }
-        }
-
-        // Case 2: Revive from idle
-        {
-            let mut idle = self.idle.lock();
-            if let Some(entry) = idle.remove(key) {
-                metrics::mcp_acquire_hit_idle(entry.idle_since.elapsed());
-                let inner = self.revive_idle_entry(entry);
-                // Re-register in active map.
-                self.active.lock().insert(key.clone(), Arc::downgrade(&inner));
-                return Ok(McpServerHandle(inner));
-            }
-        }
-
-        // Case 3: Spawn fresh
-        metrics::mcp_acquire_miss();
-        let inner = self.spawn_new(key).await?;
-        self.active.lock().insert(key.clone(), Arc::downgrade(&inner));
-        Ok(McpServerHandle(inner))
-    }
-
-    fn revive_idle_entry(&self, entry: IdleEntry) -> Arc<McpServerHandleInner> {
-        // Wrap the handle in a fresh Arc. The IdleEntry held an Arc; we're
-        // just transferring ownership here.
-        entry.handle
-    }
-
-    async fn spawn_new(&self, key: &McpServerKey) -> Result<Arc<McpServerHandleInner>> {
-        let spec = self.resolve_spec(key)?;
-        let service = McpServer::start(&spec).await?;
-        let inner = Arc::new(McpServerHandleInner {
-            key: key.clone(),
-            service: Mutex::new(Some(service)),
-            factory: Arc::downgrade(&self.weak_self()),
-            spawned_at: Instant::now(),
-        });
-        Ok(inner)
-    }
-}
-```
-
-**Concurrency in `acquire`:** the `active.lock()` critical section is short — just a hashmap lookup and maybe an insert. It never holds across an `.await`. The `idle.lock()` critical section is equally short. The `spawn_new` path is the expensive one (subprocess spawn + stdio handshake + `tools/list`), and it runs OUTSIDE any lock. This means two concurrent `acquire(key)` calls that both miss can both spawn fresh, producing two subprocesses for the same key briefly. Once both register themselves in `active`, the second insert clobbers the first, and the first handle's Drop returns it to the idle pool. The net effect is one "wasted" spawn per race, which is acceptable.
-
-If you want to eliminate the race entirely, add a per-key `OnceCell`-style coordinator:
-
-```rust
-pending: Mutex<HashMap<McpServerKey, broadcast::Receiver<Arc<McpServerHandleInner>>>>,
-```
-
-A caller that misses both active and idle checks `pending` — if another task is already spawning, it subscribes to the broadcast and waits. The first spawner publishes the result. Clean but adds a layer of complexity. Start simple; add this if races become a problem in practice.
-

-
-## The Reaper Task
-
-```rust
-async fn reaper_loop(factory: Arc<McpFactory>) {
-    let mut ticker = interval(factory.config.cleanup_interval);
-    loop {
-        ticker.tick().await;
-
-        if factory.shutdown.load(Ordering::Acquire) {
-            info!("Reaper exiting (shutdown requested)");
-            return;
-        }
-
-        factory.evict_stale_idle().await;
-
-        if let Some(policy) = &factory.config.health_check {
-            factory.run_health_checks(policy).await;
-        }
-    }
-}
-
-impl McpFactory {
-    async fn evict_stale_idle(&self) {
-        let now = Instant::now();
-        let timeout = self.config.idle_timeout;
-
-        // Phase 1: collect stale keys while holding the lock briefly.
-        let stale: Vec<McpServerKey> = {
-            let idle = self.idle.lock();
-            idle.iter()
-                .filter(|(_, entry)| now.duration_since(entry.idle_since) >= timeout)
-                .map(|(k, _)| k.clone())
-                .collect()
-        };
-
-        // Phase 2: remove them from the idle map and terminate.
-        for key in stale {
-            let entry = {
-                let mut idle = self.idle.lock();
-                idle.remove(&key)
-            };
-            if let Some(entry) = entry {
-                self.terminate_idle_handle(entry).await;
-                metrics::mcp_idle_evicted();
-            }
-        }
-
-        // Phase 3: enforce max_idle_servers cap via LRU.
-        if let Some(max) = self.config.max_idle_servers {
-            self.enforce_max_idle(max).await;
-        }
-    }
-
-    async fn enforce_max_idle(&self, max: usize) {
-        let victims: Vec<(McpServerKey, Instant)> = {
-            let idle = self.idle.lock();
-            if idle.len() <= max {
-                return;
-            }
-            let mut entries: Vec<_> = idle.iter()
-                .map(|(k, v)| (k.clone(), v.idle_since))
-                .collect();
-            entries.sort_by_key(|(_, t)| *t);  // oldest first
-            entries.into_iter().take(idle.len() - max).collect()
-        };
-
-        for (key, _) in victims {
-            let entry = self.idle.lock().remove(&key);
-            if let Some(entry) = entry {
-                self.terminate_idle_handle(entry).await;
-                metrics::mcp_lru_evicted();
-            }
-        }
-    }
-
-    async fn terminate_idle_handle(&self, entry: IdleEntry) {
-        // Take the service out of the Arc<Inner> and cancel it.
-        // At this point, there are no other Arc refs — it's just us.
-        if let Ok(inner) = Arc::try_unwrap(entry.handle) {
-            if let Some(service) = inner.service.into_inner().take() {
-                service.cancel().await.ok();
-            }
-        }
-        // If try_unwrap fails, something else grabbed a ref — skip, it'll
-        // return to idle on its own Drop.
-    }
-}
-```
-
-**Ordering:** `cleanup_interval` runs on a tokio `interval` ticker. Default is 30 seconds. Setting it too low wastes CPU; too high means idle servers linger slightly longer than `idle_timeout`. A tolerance of `idle_timeout + cleanup_interval` worst case is the tradeoff.
-
-**`Arc::try_unwrap`** is the key to safe teardown. By the time the reaper decides to evict an entry, the only Arc to that `Inner` is the one in the `IdleEntry`. Any subsequent `acquire(key)` would have removed it from the idle map first. So `try_unwrap` should always succeed — but if it doesn't (e.g., because of the Drop-race described earlier), we just skip this eviction and catch it next cycle.

-
-## The Health Check Path
-
-```rust
-impl McpFactory {
-    async fn run_health_checks(&self, policy: &HealthCheckPolicy) {
-        let now = Instant::now();
-        let candidates: Vec<McpServerKey> = {
-            let idle = self.idle.lock();
-            idle.iter()
-                .filter(|(_, entry)| {
-                    entry.last_health_check
-                        .map(|t| now.duration_since(t) >= policy.interval)
-                        .unwrap_or(true)
-                })
-                .map(|(k, _)| k.clone())
-                .collect()
-        };
-

-        // `list_tools` is cheap and standard across all MCP servers.

-}
-```
-
-Health checks are optional (`health_check: None` disables them). When enabled, they run on the same interval as the reaper and only check idle entries whose last check was more than `policy.interval` ago. This avoids hammering servers that are currently in active use.
-
---
-
-## Graceful Shutdown Integration
-
-The factory coordinates with the process shutdown signal (Ctrl-C for CLI, SIGTERM for server mode). When shutdown fires:
-
-1. Set `factory.shutdown = true`. Any subsequent `acquire()` still works but new handles won't be returned to idle on Drop.
-2. Cancel the reaper's `JoinHandle`.
-3. Drain the idle pool: walk it, call `terminate_idle_handle` for each entry.
-4. Wait for active handles to drop naturally as their scopes finish. If there's a shutdown grace period (Phase 4's `shutdown_grace_seconds`), bound the wait with that.
-
-```rust
-impl McpFactory {
-    pub async fn shutdown(&self, grace: Duration) {
-        info!("McpFactory entering shutdown");
-        self.shutdown.store(true, Ordering::Release);
-
-        // Stop the reaper.
-        if let Some(handle) = self.reaper_handle.lock().take() {
-            handle.abort();
-            let _ = handle.await;
-        }
-
-        // Drain the idle pool immediately.
-        let idle_entries: Vec<IdleEntry> = {
-            let mut idle = self.idle.lock();
-            idle.drain().map(|(_, v)| v).collect()
-        };
-        for entry in idle_entries {
-            self.terminate_idle_handle(entry).await;
-        }
-
-        // Wait for active scopes to release their handles.
-        let deadline = Instant::now() + grace;
-        while Instant::now() < deadline {
-            if self.active_count() == 0 {
-                break;
-            }
-            tokio::time::sleep(Duration::from_millis(100)).await;
-        }
-
-        // Force-terminate any remaining active handles.
-        let remaining = self.active_count();
-        if remaining > 0 {
-            warn!(count = remaining, "force-terminating MCP servers after grace period");
-            self.force_terminate_active().await;
-        }
-
-        info!("McpFactory shutdown complete");
-    }
-
-    fn active_count(&self) -> usize {
-        let active = self.active.lock();
-        active.values().filter(|w| w.strong_count() > 0).count()
-    }
-
-    async fn force_terminate_active(&self) {
-        // Walk the active map, upgrade the weak refs, and call cancel
-        // directly on the underlying service. This is a last resort.
-        let handles: Vec<Arc<McpServerHandleInner>> = {
-            let active = self.active.lock();
-            active.values().filter_map(|w| w.upgrade()).collect()
-        };
-        for handle in handles {
-            if let Ok(inner) = Arc::try_unwrap(handle) {
-                if let Some(service) = inner.service.into_inner().take() {
-                    service.cancel().await.ok();
-                }
-            }
-            // If try_unwrap fails, we can't force-kill without leaking
-            // the service. Log and move on.
-        }
-    }
-}
-```
-
-Phase 4's `serve()` function calls `factory.shutdown(grace)` after the axum server has stopped accepting new requests. This chains cleanly: axum drains requests → factory drains scopes → factory drains idle pool → process exits.
-
---
-
-## Configuration
-
-Add to `config.yaml`:
-
-```yaml
-mcp_pool:
-  idle_timeout_seconds: 300          # how long idle servers stay warm (default: 300 for --serve, 0 for CLI/REPL)
-  cleanup_interval_seconds: 30       # how often the reaper runs
-  max_idle_servers: 50               # LRU cap (null = unbounded)
-  health_check:
-    interval_seconds: 60
-    timeout_seconds: 5
-    on_failure: EvictAndLog          # or Evict, LogOnly
-```
-
-Per-server overrides live in `functions/mcp.json`:
-
-```json
-{
-  "github":     { "command": "...", "idle_timeout_seconds": 900 },
-  "filesystem": { "command": "...", "idle_timeout_seconds": 60  },
-  "jira":       { "command": "...", "idle_timeout_seconds": 300 }
-}
-```
-
-The per-server override wins over the global config. The resolution is: look up the server spec, check if it has `idle_timeout_seconds`, use that if present, else use `mcp_pool.idle_timeout_seconds`, else use the mode default (0 for CLI/REPL, 300 for `--serve`).
-
-**Mode defaults** are critical because they preserve Phase 1 Step 6.5's behavior. CLI and REPL users get `idle_timeout = 0`, which means the factory behaves exactly like the no-pool version — drop = terminate. The pool is inert for single-user scenarios. Only `--serve` mode turns it on by default. This avoids regressing REPL users who don't want MCP subprocess churn quirks.
-
-```rust
-pub fn default_idle_timeout(mode: WorkingMode) -> Duration {
-    match mode {
-        WorkingMode::Cmd | WorkingMode::Repl => Duration::ZERO,
-        WorkingMode::Api => Duration::from_secs(300),
-    }
-}
-```
-
---
-
-## Metrics
-
-Phase 5 is the right time to add basic observability counters. They're cheap and the factory is where the interesting operational questions live.
-
-```rust
-mod metrics {
-    use std::sync::atomic::{AtomicU64, Ordering};
-
-    pub static MCP_SPAWNED: AtomicU64 = AtomicU64::new(0);
-    pub static MCP_ACQUIRE_ACTIVE_HIT: AtomicU64 = AtomicU64::new(0);
-    pub static MCP_ACQUIRE_IDLE_HIT: AtomicU64 = AtomicU64::new(0);
-    pub static MCP_ACQUIRE_MISS: AtomicU64 = AtomicU64::new(0);
-    pub static MCP_IDLE_EVICTED: AtomicU64 = AtomicU64::new(0);
-    pub static MCP_LRU_EVICTED: AtomicU64 = AtomicU64::new(0);
-    pub static MCP_HEALTH_OK: AtomicU64 = AtomicU64::new(0);
-    pub static MCP_HEALTH_FAILED: AtomicU64 = AtomicU64::new(0);
-
-    pub fn mcp_acquire_hit_active() { MCP_ACQUIRE_ACTIVE_HIT.fetch_add(1, Ordering::Relaxed); }
-    pub fn mcp_acquire_hit_idle(age: Duration) {
-        MCP_ACQUIRE_IDLE_HIT.fetch_add(1, Ordering::Relaxed);
-        // In a real metrics system, record a histogram of age for revival latency.
-    }
-    pub fn mcp_acquire_miss() { MCP_ACQUIRE_MISS.fetch_add(1, Ordering::Relaxed); }
-    pub fn mcp_spawned() { MCP_SPAWNED.fetch_add(1, Ordering::Relaxed); }
-    pub fn mcp_idle_evicted() { MCP_IDLE_EVICTED.fetch_add(1, Ordering::Relaxed); }
-    pub fn mcp_lru_evicted() { MCP_LRU_EVICTED.fetch_add(1, Ordering::Relaxed); }
-    pub fn mcp_health_ok() { MCP_HEALTH_OK.fetch_add(1, Ordering::Relaxed); }
-    pub fn mcp_health_failed() { MCP_HEALTH_FAILED.fetch_add(1, Ordering::Relaxed); }
-
-    pub fn snapshot() -> MetricsSnapshot {
-        MetricsSnapshot {
-            spawned: MCP_SPAWNED.load(Ordering::Relaxed),
-            acquire_active_hit: MCP_ACQUIRE_ACTIVE_HIT.load(Ordering::Relaxed),
-            acquire_idle_hit: MCP_ACQUIRE_IDLE_HIT.load(Ordering::Relaxed),
-            acquire_miss: MCP_ACQUIRE_MISS.load(Ordering::Relaxed),
-            idle_evicted: MCP_IDLE_EVICTED.load(Ordering::Relaxed),
-            lru_evicted: MCP_LRU_EVICTED.load(Ordering::Relaxed),
-            health_ok: MCP_HEALTH_OK.load(Ordering::Relaxed),
-            health_failed: MCP_HEALTH_FAILED.load(Ordering::Relaxed),
-        }
-    }
-}
-```
-
-Expose the snapshot via `GET /v1/info/mcp` in the API server (piggybacks on Phase 4's `/v1/info`). CLI/REPL users can inspect via a new `.info mcp` dot-command.
-
-**Derived metrics worth computing:**
- Hit rate = `(active_hit + idle_hit) / (active_hit + idle_hit + miss)` — should be >0.9 for a well-tuned pool.
- Revival latency distribution — how old were idle entries when revived? Informs tuning of `idle_timeout`.
- Eviction rate — how often is the pool churning?
-
-None of this is Prometheus-compatible yet; that integration is a follow-up. For Phase 5, plain counters are enough to diagnose issues.
-
---
-
-## Migration Strategy
-
-### Step 1: Expand `McpFactory` to support the idle pool
-
-Add the `idle` map, `shutdown` flag, and `reaper_handle` fields. Keep the existing `active` map. Don't change any caller code yet.
-
-Implement `acquire()` with the three-case logic (active → idle → spawn). At this point the idle pool is always empty because nothing puts anything in it, so the logic reduces to Phase 1's behavior. Tests should still pass.
-
-**Verification:** `cargo check` + existing Phase 1 tests pass.
-
-### Step 2: Implement `Drop` on `McpServerHandleInner` with return-to-idle
-
-Switch `service` to `Mutex<Option<RunningService>>`. Implement `Drop` that spawns a task to call `factory.accept_returning_handle(key, service)`. The factory method inserts into `idle`.
-
-At this point, dropped handles start populating the idle pool. The reaper isn't running yet, so idle entries accumulate without bound.
-
-**Verification:** Manual test: acquire a handle, drop it, assert the idle map now has the entry. Then acquire the same key again and assert it comes from idle (not a fresh spawn).
-
-### Step 3: Implement the reaper task
-
-Add `reaper_loop` and `evict_stale_idle`. Start the reaper in `McpFactory::new()` via `tokio::spawn`, store the `JoinHandle`. Default `idle_timeout` based on working mode.
-
-**Verification:** Unit test with a tiny timeout (e.g., 100ms) — acquire, drop, wait 200ms, assert the idle map is empty. Use a mock MCP server (or a no-op `RunningService` for tests).
-
-### Step 4: Add configuration plumbing
-
-Parse `mcp_pool` from `config.yaml` into `McpFactoryConfig`. Parse per-server `idle_timeout_seconds` overrides from `functions/mcp.json`. Wire everything through `AppState::init()`.
-
-**Verification:** Config tests that verify defaults, overrides, and mode-specific behavior.
-
-### Step 5: Implement health checks
-
-Add `run_health_checks`, `ping_handle`, and the `HealthCheckPolicy` config. Wire into the reaper loop. Default is `None` (disabled).
-
-**Verification:** Unit test with a mock MCP server that returns an error on `list_tools` after N calls — verify the factory evicts it and logs.
-
-### Step 6: Implement graceful shutdown
-
-Add `McpFactory::shutdown(grace)`. Wire into Phase 4's `serve()` shutdown sequence and into the CLI/REPL exit path (for clean subprocess termination).
-
-**Verification:** Start the API server, send several requests to warm up the pool, send SIGTERM, verify all MCP subprocesses terminate within the grace period (use `ps` or process tree inspection).
-
-### Step 7: Expose metrics
-
-Add the atomic counters, the snapshot function, and the `.info mcp` dot-command. Add `GET /v1/info/mcp` handler in the API server.
-
-**Verification:** `.info mcp` shows sensible numbers after a few REPL turns. `/v1/info/mcp` returns JSON. Hit rate climbs over time as the pool warms.
-
-### Step 8: Load testing
-
-Write a test harness that spins up `--serve` mode and fires 100 concurrent completion requests, each using a mix of 2–3 MCP servers, across a pool of 10 different server configurations. Assert:
-
- No test failures
- No orphaned subprocesses (check `ps` before and after)
- MCP spawn count stays low (hit rate >80%)
- p99 latency for the warm path is <200ms (allowing for LLM latency)
-
-This is the practical validation that Phase 5 delivered on its performance promise.
-
-**Verification:** Load test passes. Metrics snapshot shows expected hit rate.
-
-### Step 9: Document tuning knobs
-
-Update `docs/function-calling/MCP-SERVERS.md` with the new config options and tuning guidance:
-
- How to choose `idle_timeout` for different workloads
- When to enable health checks
- How to read the metrics
- What the `max_idle_servers` cap protects against
-
-Add an "MCP Pool Lifecycle" section to `docs/REST-API-ARCHITECTURE.md` describing the production topology.

-
-## Risks and Watch Items
-
-| Risk | Severity | Mitigation |
-|---|---|---|
-| **Drop-race between `acquire` and `return_to_idle`** | Medium | The `tokio::spawn` inside Drop runs asynchronously. If an `acquire(key)` fires between Drop and the spawned task completing, it misses the idle pool and spawns fresh. Acceptable for correctness; monitor hit rate metrics, switch to the mpsc coordinator pattern if races show up in production. |
-| **`Arc::try_unwrap` failing in `terminate_idle_handle`** | Medium | If something holds an extra Arc to an idle entry (shouldn't happen under normal flow), `try_unwrap` returns `Err` and we skip eviction. The entry stays in the idle map forever. Mitigation: log every such failure with a WARN. Write a test that verifies the shape never produces such extra refs. |
-| **`tokio::time::interval` drift** | Low | `interval` drifts if the system is under load — a tick can be delayed. This means `cleanup_interval` is a lower bound, not a guarantee. For a 30-second interval this is irrelevant; document it. |
-| **Reaper task panic** | Medium | If the reaper task panics (unreachable under normal flow, but possible under library bugs), the pool stops cleaning up. Mitigation: wrap the reaper body in `tokio::task::JoinHandle` inspection, restart on failure. Add a metric for reaper restarts. |
-| **MCP server state on revival** | High | Reviving a server from idle assumes it's still in the same state it was when it went idle. Most MCP servers are stateless (they reload config on each tool call), but some might maintain in-memory state that's stale after 5 minutes of idle. Mitigation: health checks during idle provide an early warning; document that pool idle is only safe for stateless servers. |
-| **Credential rotation** | High | If the user rotates their GitHub token (or any MCP-server-side credential), the idle pool entries hold the old credential baked into the subprocess env. A rotation requires restarting affected MCP servers. Mitigation: expose a `.reload mcp` REPL command and `POST /v1/mcp/reload` API that clears the idle pool, forcing fresh spawns with the new credentials on next acquire. |
-| **Per-server timeout resolution** | Low | The `idle_timeout` lookup (per-server override → pool default → mode default) happens at `return_to_idle` time. Changing config at runtime won't affect already-idle entries. Document this; config reload flushes idle pool. |
-| **`max_idle_servers` thrashing** | Medium | If the cap is set too low relative to the working set, every new `acquire` evicts an old idle entry, destroying the hit rate. Default to 50, document the signal: rising eviction rate + falling hit rate = raise the cap. |
-| **Subprocess leak on factory drop** | High | If `AppState` (which owns `McpFactory`) drops without calling `shutdown()`, the idle pool Arc holds die, their Drops run, but the factory's Weak self-ref is already dead so nothing puts them back in idle — they just terminate via `RunningService::drop`. Verify this actually fires cleanly (not via the tokio::spawn hack). Add a test. |
-

-
-## What Phase 5 Does NOT Do
-
- **No LLM response caching.** The factory pools MCP subprocesses, not LLM responses.
- **No distributed pooling.** A single factory instance owns its pool. Running multiple Loki server instances means each has its own pool; MCP processes are not shared across hosts.
- **No background server restart on crash.** If an MCP subprocess dies while idle, the reaper's health check evicts it; the next `acquire` spawns fresh. There's no "always keep N warm" preflight.
- **No OAuth token refresh for MCP.** If a server uses OAuth and its token expires during an idle period, the next `acquire` gets an expired handle. The server must handle its own refresh, or the user must rotate and `.reload mcp`.
- **No Prometheus integration.** Plain atomic counters; Prometheus support is a follow-up.
- **No adaptive tuning.** `idle_timeout` is a fixed config value, not auto-adjusted based on usage patterns.
- **No cross-process coordination.** Two Loki processes running `--serve` on the same host each have independent pools. They can't share MCP subprocesses across processes.
- **No changes to the factory's public API.** `acquire()` still takes `&McpServerKey`, still returns `McpServerHandle`. Callers don't notice Phase 5 happened.
-
-The sole goal of Phase 5 is: **make the warm path free by keeping recently-used MCP subprocesses alive, with automatic eviction of stale ones, a background reaper, health checks, and graceful shutdown integration.**

-# Phase 6 Implementation Plan: Production Hardening
-
-## Overview
-
-Phase 6 closes out the refactor by picking up every "deferred to production hardening" item from Phases 1–5 and delivering a Loki build that's safe to run as a multi-tenant service. The preceding phases made Loki *functionally* a server — Phase 6 makes it *operationally* a server. That means real rate limiting instead of a stub, per-subject session ownership instead of flat visibility, Prometheus metrics instead of in-memory counters, structured JSON logging, deployment manifests, security headers, config validation, and operational runbooks.
-
-This is the final phase. After it lands, Loki v1 is production-ready: you can run `loki --serve` in a container behind a reverse proxy, scrape its metrics from Prometheus, route requests through a rate limiter, and have multiple tenants share the same instance without seeing each other's data.
-
-**Estimated effort:** ~1 week
-**Risk:** Low. Most of the work is applying well-known patterns (sliding-window rate limiting, row-level authz, Prometheus, structured logging) on top of the architecture the previous phases already built. No new core types, no new pipelines.
-**Depends on:** Phases 1–5 complete. The API server runs, MCP pool works, sessions are UUID-keyed.
-
---
-
-## Why Phase 6 Exists
-
-Phases 4 and 5 got the API server running with correct semantics, but several explicit gaps were called out as "stubs" or "follow-ups." A Phase 4 deployment is usable for a trusted single-tenant context (an internal tool, a personal server) but unsafe for anything else:
-
- **Anyone with a valid API key can see every session.** Phase 4 flagged this as "single-tenant-per-key." In a multi-tenant deployment where Alice and Bob both have keys, Alice can list Bob's sessions and read their messages. This is a security issue, not a feature gap.
- **No real rate limiting.** Phase 4's `max_concurrent_requests` semaphore caps parallelism but doesn't throttle per-subject request rates. A single runaway client can exhaust the whole concurrency budget.
- **No metrics for external observability.** Phase 5 added in-memory counters, but they're only reachable via the `.info mcp` dot-command or a one-shot JSON endpoint. Production needs Prometheus scraping so alerting and dashboards work.
- **Logs aren't structured.** The `tracing` spans from Phase 4 middleware emit human-readable text. Aggregators like Loki (the other one), Datadog, or CloudWatch want JSON with correlation IDs.
- **No deployment story.** There's no Dockerfile, no systemd unit, no documented way to actually run the thing in production. Every deploying team has to reinvent this.
- **Security headers missing.** Phase 4's CORS handles cross-origin; it doesn't set `X-Content-Type-Options`, `X-Frame-Options`, or similar defaults that a browser-facing endpoint should have.
- **No config validation at startup.** Mistyped config values produce runtime errors hours after deployment instead of failing fast at startup.
- **Operational procedures are undocumented.** How do you rotate auth keys? How do you reload MCP credentials? What's the runbook when the MCP hit rate drops? None of this is written down.
-
-Phase 6 delivers answers to all of the above. It's the "you can actually deploy this" phase.
-
---
-
-## What Phase 6 Delivers
-
-Grouped by theme rather than by dependency order. Each item is independently valuable and can be worked in parallel.
-
-### Security and isolation
-
-1. **Per-subject session ownership** — every session records the authenticated subject that created it; reads/writes are authz-checked against the caller's subject.
-2. **Scope-based authorization** — `AuthContext.scopes` are enforced per endpoint (e.g., `read:sessions`, `write:sessions`, `admin:mcp`). Phase 4's middleware already populates scopes; Phase 6 adds the enforcement.
-3. **JWT support** — extends `AuthConfig` with a `Jwt { issuer, audience, jwks_url }` variant that validates tokens against a JWKS endpoint and extracts subject + scopes from claims.
-4. **Security headers middleware** — `X-Content-Type-Options: nosniff`, `X-Frame-Options: DENY`, `Referrer-Policy: strict-origin`, optional HSTS when behind HTTPS.
-5. **Audit logging** — structured audit events for every authenticated request (subject, action, target, result), written to a dedicated sink so they survive log rotation.
-
-### Throughput and fairness
-
-6. **Per-subject rate limiting** — sliding-window limiter keyed by subject. Enforces `rate_limit_per_minute` and related config. Returns `429 Too Many Requests` with a `Retry-After` header.
-7. **Per-subject concurrency limit** — subject-scoped semaphore so one noisy neighbor can't exhaust the global concurrency budget.
-8. **Backpressure signal** — expose a `/healthz/ready` endpoint that returns 503 when the server is saturated, so upstream load balancers can drain traffic.
-
-### Observability
-
-9. **Structured JSON logging** — every log line is JSON with `timestamp`, `level`, `target`, `request_id`, `subject`, `session_id`, and `fields`. Routes through `tracing_subscriber` with `fmt::layer().json()`.
-10. **Prometheus metrics endpoint** — `/metrics` exposing the existing Phase 5 counters plus new HTTP metrics (`http_requests_total`, `http_request_duration_seconds`, `http_requests_in_flight`), MCP metrics (`mcp_pool_size`, `mcp_acquire_latency_seconds` histogram), and session metrics (`sessions_active_total`, `sessions_created_total`).
-11. **Liveness and readiness probes** — `/healthz/live` for process liveness (always 200 unless shutting down), `/healthz/ready` for dependency readiness (config loaded, MCP pool initialized, storage writable).
-
-### Operability
-
-12. **Config validation at startup** — a dedicated `ApiConfig::validate()` that checks every field against a schema and fails fast with a readable error message listing *all* problems, not just the first one.
-13. **SIGHUP config reload** — reloads auth keys, log level, and rate limit settings without restarting the server. Does NOT reload MCP pool config (requires restart because the pool holds live subprocesses).
-14. **Dockerfile + multi-stage build** — minimal runtime image based on `debian:bookworm-slim` with the compiled binary, config directory, and non-root user.
-15. **systemd service unit** — with `Type=notify`, sandboxing directives, and resource limits.
-16. **docker-compose example** — for local development with nginx-as-TLS-terminator in front.
-17. **Kubernetes manifests** — Deployment, Service, ConfigMap, Secret, HorizontalPodAutoscaler.
-
-### Documentation
-
-18. **Operational runbook** (`docs/RUNBOOK.md`) — documented procedures for common scenarios.
-19. **Deployment guide** (`docs/DEPLOYMENT.md`) — end-to-end instructions for each deployment target.
-20. **Security guide** (`docs/SECURITY.md`) — threat model, hardening checklist, key rotation procedures.

-## Core Type Additions
-
-Most of Phase 6 hangs off existing types. A few new concepts need introducing.
-
-### `AuthContext` enrichment
-
-Phase 4 defined `AuthContext { subject: String, scopes: Vec<String> }`. Phase 6 extends it:
-
-```rust
-pub struct AuthContext {
-    pub subject: String,
-    pub scopes: Scopes,
-    pub key_id: Option<String>,        // for audit log correlation
-    pub claims: Option<JwtClaims>,     // present when auth mode is Jwt
-}
-
-pub struct Scopes(HashSet<String>);
-
-impl Scopes {
-    pub fn has(&self, scope: &str) -> bool;
-    pub fn has_any(&self, required: &[&str]) -> bool;
-    pub fn has_all(&self, required: &[&str]) -> bool;
-}
-
-pub enum Scope {
-    ReadSessions,      // "read:sessions"
-    WriteSessions,     // "write:sessions"
-    ReadAgents,        // "read:agents"
-    RunAgents,         // "run:agents"
-    ReadModels,        // "read:models"
-    AdminMcp,          // "admin:mcp"
-    AdminSessions,     // "admin:sessions" — can see all users' sessions
-}
-```
-
-The `Scope` enum provides typed constants for the well-known scope strings used in the handlers. Custom scopes (for callers to define their own access tiers) continue to work as raw strings.
-
-### `SessionOwnership` in the session store
-
-The session metadata needs to record who owns each session so reads/writes can be authorized:
-
-```rust
-pub struct SessionMeta {
-    pub id: SessionId,
-    pub alias: Option<SessionAlias>,
-    pub owner: Option<String>,         // subject that created it; None = legacy
-    pub last_modified: SystemTime,
-    pub is_autoname: bool,
-}
-```
-
-On disk, the ownership field goes into the session's YAML file under a reserved `_meta` block:
-
-```yaml
-_meta:
-  owner: "alice"
-  created_at: "2026-04-10T15:32:11Z"
-  created_by_key_id: "key_3f2a..."
-# ... rest of session fields unchanged
-```
-
-The `SessionStore` trait gets two new methods and an enriched `open` signature:
-
-```rust
-#[async_trait]
-pub trait SessionStore: Send + Sync {
-    // existing methods unchanged except:
-    async fn open(
-        &self,
-        agent: Option<&str>,
-        id: SessionId,
-        caller: Option<&AuthContext>,  // NEW: for authz check
-    ) -> Result<SessionHandle, StoreError>;
-
-    async fn list(
-        &self,
-        agent: Option<&str>,
-        caller: Option<&AuthContext>,  // NEW: for filtering
-    ) -> Result<Vec<SessionMeta>, StoreError>;
-
-    // NEW: transfer ownership (e.g., admin reassignment)
-    async fn set_owner(
-        &self,
-        id: SessionId,
-        new_owner: Option<String>,
-    ) -> Result<(), StoreError>;
-}
-```
-
-`caller: None` means internal or legacy access (CLI/REPL) — skip authz entirely. `caller: Some(...)` means an API call — enforce ownership.
-
-**Authz rules:**
- Own session: full access.
- Other subject's session: denied unless caller has `admin:sessions` scope.
- Legacy sessions with `owner: None`: accessible to anyone (grandfathered); every mutation attempts to set the owner to the current caller so they get claimed forward.
- `list`: returns only sessions owned by the caller (or all if they have `admin:sessions`).
-
-### `RateLimiter` and `ConcurrencyLimiter`
-
-```rust
-pub struct RateLimiter {
-    windows: DashMap<String, SlidingWindow>,
-    config: RateLimitConfig,
-}
-
-struct SlidingWindow {
-    bucket_a: AtomicU64,
-    bucket_b: AtomicU64,
-    last_reset: AtomicU64,
-}
-
-pub struct RateLimitConfig {
-    pub per_minute: u32,
-    pub burst: u32,
-}
-
-impl RateLimiter {
-    pub fn check(&self, subject: &str) -> Result<(), RateLimitError>;
-}
-
-pub struct RateLimitError {
-    pub retry_after: Duration,
-    pub limit: u32,
-    pub remaining: u32,
-}
-
-pub struct SubjectConcurrencyLimiter {
-    semaphores: DashMap<String, Arc<Semaphore>>,
-    per_subject: usize,
-}
-
-impl SubjectConcurrencyLimiter {
-    pub async fn acquire(&self, subject: &str) -> OwnedSemaphorePermit;
-}
-```
-
-Both live in `ApiState` and are applied via middleware. Rate limiting runs first (cheap atomic operations), then concurrency acquisition (may block briefly).
-
-### `MetricsRegistry`
-
-```rust
-pub struct MetricsRegistry {
-    pub http_requests_total: IntCounterVec,
-    pub http_request_duration: HistogramVec,
-    pub http_requests_in_flight: IntGaugeVec,
-    pub sessions_active: IntGauge,
-    pub sessions_created_total: IntCounter,
-    pub mcp_pool_size: IntGaugeVec,
-    pub mcp_acquire_latency: HistogramVec,
-    pub mcp_spawns_total: IntCounter,
-    pub mcp_idle_evictions_total: IntCounter,
-    pub auth_failures_total: IntCounterVec,
-    pub rate_limit_rejections_total: IntCounterVec,
-}
-```
-
-Built on top of the `prometheus` crate. Exposed via `GET /metrics` with the Prometheus text exposition format. The registry bridges Phase 5's atomic counters into the Prometheus types without requiring Phase 5's code to change — Phase 5 keeps its simple counters, and Phase 6 reads them on each scrape to populate the Prometheus gauges.
-
-### `AuditLogger`
-
-```rust
-pub struct AuditLogger {
-    sink: AuditSink,
-}
-
-pub enum AuditSink {
-    Stderr,                                 // default
-    File { path: PathBuf, rotation: Rotation },
-    Syslog { facility: String },
-}
-
-pub struct AuditEvent<'a> {
-    pub timestamp: OffsetDateTime,
-    pub request_id: Uuid,
-    pub subject: Option<&'a str>,
-    pub action: AuditAction,
-    pub target: Option<&'a str>,
-    pub result: AuditResult,
-    pub details: Option<serde_json::Value>,
-}
-
-pub enum AuditAction {
-    SessionCreate,
-    SessionRead,
-    SessionUpdate,
-    SessionDelete,
-    AgentActivate,
-    ToolExecute,
-    McpReload,
-    ConfigReload,
-    AuthFailure,
-    RateLimitRejection,
-}
-
-pub enum AuditResult {
-    Success,
-    Denied { reason: String },
-    Error { message: String },
-}
-
-impl AuditLogger {
-    pub fn log(&self, event: AuditEvent<'_>);
-}
-```
-
-Audit events are emitted from handler middleware after request completion. The audit stream is deliberately separate from the regular tracing logs because audit logs have stricter retention/integrity requirements in regulated environments — you want to be able to pipe them to a WORM storage or SIEM without mixing in debug logs.
-
---
-
-## Migration Strategy
-
-### Step 1: Per-subject session ownership
-
-The highest-impact security fix. No new deps, no new config — just enriching existing types.
-
-1. Add `owner: Option<String>` and `created_by_key_id: Option<String>` to the session YAML `_meta` block. Serde skip if absent (backward compat for legacy files).
-2. Update `SessionStore::create` to record the caller's subject.
-3. Update `SessionStore::open` to take `caller: Option<&AuthContext>` and enforce ownership.
-4. Update `SessionStore::list` to filter by caller subject (unless caller has `admin:sessions` scope).
-5. Add `SessionStore::set_owner` for admin reassignment.
-6. Implement the "claim on first mutation" behavior for legacy sessions.
-7. Update all API handlers to pass the `AuthContext` through to store calls.
-8. Add integration tests: Alice creates a session, Bob tries to read it (403), admin Claire can read it (200), Alice's `list` returns only her own, Claire's `list` with `admin:sessions` scope returns everything.
-
-**Verification:** all new authz tests pass. CLI/REPL tests still pass because they pass `caller: None`.
-
-### Step 2: Scope-based authorization for endpoints
-
-Phase 4's middleware attaches `AuthContext` with a `scopes: Vec<String>` field but handlers don't check it. Phase 6 adds the enforcement.
-
-1. Change `AuthContext.scopes` from `Vec<String>` to a `Scopes(HashSet<String>)` newtype with `has`/`has_any`/`has_all` methods.
-2. Define the `Scope` enum with well-known constants.
-3. Add a `require_scope` helper and a `#[require_scope("read:sessions")]` proc macro (or a handler-side check if proc macros add too much complexity).
-4. Annotate every handler with the required scope(s):
-   - `GET /v1/sessions` → `read:sessions`
-   - `POST /v1/sessions` → `write:sessions`
-   - `GET /v1/sessions/:id` → `read:sessions`
-   - `DELETE /v1/sessions/:id` → `write:sessions`
-   - `POST /v1/sessions/:id/completions` → `write:sessions` + `run:agents` (if the session has an agent)
-   - `POST /v1/rags/:name/rebuild` → `admin:mcp`
-   - `GET /v1/agents`, `/v1/roles`, `/v1/rags`, `/v1/models` → `read:agents`, `read:roles`, etc.
-   - `/metrics` → `admin:metrics` (or unauthenticated if the endpoint is bound to a private network)
-5. Document the scope model in `docs/SECURITY.md`.
-
-**Verification:** per-endpoint authz tests. A key with only `read:sessions` can list and read but not write.
-
-### Step 3: JWT support in `AuthConfig`
-
-Extend the auth mode enum:
-
-```rust
-pub enum AuthConfig {
-    Disabled,
-    StaticKeys { keys: Vec<AuthKeyEntry> },
-    Jwt(JwtConfig),
-}
-
-pub struct JwtConfig {
-    pub issuer: String,
-    pub audience: String,
-    pub jwks_url: String,
-    pub jwks_refresh_interval: Duration,
-    pub subject_claim: String,        // e.g., "sub"
-    pub scopes_claim: String,         // e.g., "scope" or "permissions"
-    pub leeway_seconds: u64,
-}
-```
-
-1. Add `jsonwebtoken` and `reqwest` (already present) to dependencies.
-2. Implement a `JwksCache` that fetches `jwks_url` on startup and refreshes every `jwks_refresh_interval`. Uses `reqwest` with a short timeout. Refreshes in the background via `tokio::spawn`.
-3. The auth middleware branches on `AuthConfig`: `StaticKeys` continues to work, `Jwt` calls `jsonwebtoken::decode` with the cached JWKS.
-4. Extract subject from the configured claim name. Extract scopes from either a space-separated string (`scope` claim) or an array claim (`permissions`).
-5. Handle key rotation gracefully: if decoding fails with "unknown key ID," trigger an immediate JWKS refresh (debounced to once per minute) and retry once.
-6. Integration tests with a fake JWKS endpoint (use `mockito` or `wiremock`).
-
-**Verification:** valid JWT authenticates; expired JWT rejected; invalid signature rejected; JWKS refresh handles key rotation.
-
-### Step 4: Real rate limiting
-
-Replace the Phase 4 stub with a working sliding-window implementation.
-
-1. Add `dashmap` dependency for the per-subject map (lock-free reads/writes).
-2. Implement `SlidingWindow` with two adjacent one-minute buckets; the effective rate is the weighted sum of the current bucket plus the tail of the previous bucket based on how far into the current window we are.
-3. Add `RateLimiter::check(subject) -> Result<(), RateLimitError>`.
-4. Write middleware that calls `check` before dispatching to handlers. On `Err`, return 429 with `Retry-After` header.
-5. Add `rate_limit_per_minute` and `rate_limit_burst` config fields. Reasonable defaults: 60/min, burst 10.
-6. Expose per-subject current rate as a gauge in the Prometheus registry.
-7. Integration test: fire N+1 requests as the same subject within a minute, assert the N+1th gets 429.
-
-**Verification:** rate limiting works correctly across subjects; non-limited subjects aren't affected; burst allowance works.
-
-### Step 5: Per-subject concurrency limiter
-
-Complements rate limiting — rate limits the *count* of requests over time, concurrency limits the *simultaneous* count.
-
-1. Implement `SubjectConcurrencyLimiter` with a `DashMap<String, Arc<Semaphore>>`.
-2. Lazy-init semaphores per subject with `per_subject_concurrency` slots (default 8).
-3. Middleware acquires a permit per request. If the subject's semaphore is full, queue briefly (`try_acquire_owned` with a short timeout), then 503 if still full.
-4. Garbage-collect unused semaphores periodically (entries with no waiters and full availability count haven't been used).
-5. Integration test: fire 10 concurrent requests as one subject with `per_subject_concurrency: 5`, assert at least 5 serialize.
-
-**Verification:** no subject can exceed its concurrency budget; other subjects unaffected.
-
-### Step 6: Prometheus metrics endpoint
-
-1. Add `prometheus` crate.
-2. Implement `MetricsRegistry` with the metrics listed in the types section.
-3. Wire metric updates into existing code:
-   - HTTP middleware: `http_requests_total.inc()` on response, `http_request_duration.observe(elapsed)`, `http_requests_in_flight.inc()/dec()`
-   - Session creation: `sessions_created_total.inc()`, `sessions_active.set(store.count())`
-   - MCP factory: read the Phase 5 atomic counters on scrape and populate the Prometheus types
-4. Add `GET /metrics` handler that writes the Prometheus text exposition format.
-5. Auth policy for `/metrics`: configurable — either requires `admin:metrics` scope, or is opened to a private network via `metrics_listen_addr: "127.0.0.1:9090"` on a separate port (recommended).
-6. Integration test: scrape `/metrics`, parse the response, assert expected metrics are present with sensible values.
-
-**Verification:** Prometheus scraping works; metrics increment correctly.
-
-### Step 7: Structured JSON logging
-
-Replace the default `tracing_subscriber` format with JSON output.
-
-1. Add a `log_format: Text | Json` config field, default `Text` for CLI/REPL, `Json` for `--serve` mode.
-2. Configure `tracing_subscriber::fmt::layer().json()` conditionally.
-3. Ensure every span has a `request_id` field (already present from Phase 4 middleware).
-4. Add `subject` and `session_id` as span fields when present, so they get included in every child log line automatically.
-5. Add a `log_level` config field that SIGHUP reloads at runtime (see Step 12).
-6. Integration test: capture stdout during a request, parse as JSON, assert the fields are present and correctly scoped.
-
-**Verification:** `loki --serve` produces one-line-per-event JSON output suitable for log aggregators.
-
-### Step 8: Audit logging
-
-Dedicated sink for security-relevant events.
-
-1. Implement `AuditLogger` with `Stderr`, `File`, and `Syslog` sinks. Start with just `Stderr` and `File` — `Syslog` via `syslog` crate can follow.
-2. Emit audit events from:
-   - Auth middleware: `AuditAction::AuthFailure` on any auth rejection
-   - Rate limiter: `AuditAction::RateLimitRejection` on 429
-   - Session handlers: `AuditAction::SessionCreate/Read/Update/Delete`
-   - Agent handlers: `AuditAction::AgentActivate`
-   - MCP reload endpoint: `AuditAction::McpReload`
-3. Audit events are JSON lines with a schema documented in `docs/SECURITY.md`.
-4. Audit events don't interfere with the main tracing stream — they go to the configured audit sink independently.
-5. File rotation via `tracing-appender` or manual rotation with size + date cap.
-
-**Verification:** every security-relevant action produces an audit event; failures include a `reason`.
-
-### Step 9: Security headers and misc middleware
-
-1. Add a `security_headers` middleware layer that attaches:
-   - `X-Content-Type-Options: nosniff`
-   - `X-Frame-Options: DENY`
-   - `Referrer-Policy: strict-origin-when-cross-origin`
-   - `Strict-Transport-Security: max-age=31536000; includeSubDomains` (only when `api.force_https: true`)
-   - Do NOT set CSP — this is an API, not a browser app; CSP would confuse clients.
-2. Remove `Server: ...` and other fingerprinting headers.
-3. Handle `OPTIONS` preflight correctly (Phase 4's CORS layer does this; verify).
-
-**Verification:** `curl -I` inspects headers; automated test asserts each required header is present.
-
-### Step 10: Config validation at startup
-
-A single `ApiConfig::validate()` method that checks every field and aggregates ALL errors before failing.
-
-1. Implement validation for:
-   - `listen_addr` is parseable and bindable
-   - `auth.mode` has a valid configuration (e.g., `StaticKeys` with non-empty key list, `Jwt` with reachable JWKS URL)
-   - `auth.keys[].key_hash` starts with `$argon2id$` (catches plaintext keys)
-   - `rate_limit_per_minute > 0` and `burst > 0`
-   - `max_body_bytes > 0` and `< 100 MiB` (sanity)
-   - `request_timeout_seconds > 0` and `< 3600`
-   - `shutdown_grace_seconds >= 0`
-   - `cors.allowed_origins` entries are valid URLs or `"*"`
-2. Return a `ConfigValidationError` that lists every problem, not just the first.
-3. Call `validate()` in `serve()` before binding the listener.
-4. Test: a deliberately-broken config produces an error listing all problems.
-
-**Verification:** startup validation catches common mistakes; error message is actionable.
-
-### Step 11: Health check endpoints
-
-1. `GET /healthz/live` — always returns 200 OK unless the process is in graceful shutdown. Body: `{"status":"ok"}`. No auth required.
-2. `GET /healthz/ready` — returns 200 OK when fully initialized and not saturated, otherwise 503 Service Unavailable. Readiness criteria:
-   - `AppState` fully initialized
-   - Session store writable (attempt a probe write to a reserved path)
-   - MCP pool initialized (at least the factory is alive)
-   - Concurrency semaphore has at least 10% available (not saturated)
-3. Both endpoints are unauthenticated and unmetered — load balancers hit them constantly.
-4. Document in `docs/DEPLOYMENT.md` how Kubernetes, systemd, and other supervisors should use these.
-
-**Verification:** endpoints return correct status under various load conditions.
-
-### Step 12: SIGHUP config reload
-
-Reload a subset of config without restarting.
-
-1. Reloadable fields:
-   - Auth keys (StaticKeys mode)
-   - JWT config (including JWKS URL)
-   - Log level
-   - Rate limit config
-   - Per-subject concurrency limits
-   - Audit logger sink
-2. NOT reloadable (requires full restart):
-   - Listen address
-   - MCP pool config (pool holds live subprocesses)
-   - Session storage paths
-   - TLS certs (use a reverse proxy)
-3. Implementation: SIGHUP handler that re-reads `config.yaml`, validates it, and atomically swaps the affected fields in `ApiState`. Uses `arc-swap` crate for lock-free swaps.
-4. Audit every reload: `AuditAction::ConfigReload` with before/after diff summary.
-5. Document: rotation procedures for auth keys, logging level adjustments, etc.
-
-**Verification:** start server, modify `config.yaml`, send SIGHUP, assert new config is in effect without dropped requests.
-
-### Step 13: Deployment manifests
-
-#### 13a. Dockerfile
-
-Multi-stage build for a minimal runtime image:
-
-```dockerfile
-# Build stage
-FROM rust:1.82-slim AS builder
-WORKDIR /build
-COPY Cargo.toml Cargo.lock ./
-COPY src ./src

- `secret.yaml` (API keys, JWT config)
- `hpa.yaml` (HorizontalPodAutoscaler based on CPU + custom metric for requests/sec)
- `ingress.yaml` (optional example using nginx-ingress)
-
-Document storage strategy: sessions use a PVC mounted at `/loki/data`; RAG embeddings use a read-only ConfigMap or a separate PVC.
-
-**Verification:** each deployment target produces a running Loki that passes health checks.
-
-### Step 14: Operational runbook
-
-Write `docs/RUNBOOK.md` with sections for:
-
- **Starting and stopping** the server
- **Rotating auth keys** (StaticKeys mode) — edit config, SIGHUP, verify in audit log
- **Rotating auth keys** (Jwt mode) — update JWKS at issuer, Loki auto-refreshes
- **Rotating MCP credentials** — update env vars, `POST /v1/mcp/reload` (new endpoint in this phase) or restart
- **Diagnosing high latency** — check MCP hit rate, check LLM provider latency, check concurrency saturation
- **Diagnosing auth failures** — audit log `AuthFailure` events, check key hash, check JWKS reachability
- **Diagnosing rate limit rejections** — check per-subject counter, adjust limit or identify runaway client
- **Diagnosing orphaned MCP subprocesses** — `ps aux | grep loki`, check logs for `McpFactory shutdown complete`
- **Diagnosing session corruption** — check `.yaml.tmp` files (should not exist when server is idle), inspect session YAML for validity
- **Backup and restore** — tar the `sessions/` and `agents/` directories
- **Scaling horizontally** — each replica has its own MCP pool and session store; share sessions via shared filesystem (NFS/EFS) or deferred to a database-backed SessionStore (not in this phase)
- **Incident response** — what logs to collect, what metrics to snapshot, how to reach a minimal reproducing state
-
-**Verification:** walk through each procedure on a test deployment; fix any unclear steps.
-
-### Step 15: Deployment and security guides
-
-`docs/DEPLOYMENT.md` — step-by-step for Docker, systemd, docker-compose, Kubernetes. Pre-flight checklist, first-time setup, upgrade procedure.
-
-`docs/SECURITY.md` — threat model, hardening checklist, scope model, audit event schema, key rotation, reverse proxy configuration, network security recommendations, CVE reporting contact.
-
-Cross-reference from `README.md` and add a "Production Deployment" section to the README that points to both docs.
-
-**Verification:** a developer unfamiliar with Loki can deploy it successfully using only the docs.

-## Risks and Watch Items
-
-| Risk | Severity | Mitigation |
-|---|---|---|
-| **Session ownership migration breaks legacy users** | Medium | Legacy sessions with `owner: None` stay readable by anyone; they get claimed forward on first mutation. Document this in `RUNBOOK.md`. Add a one-shot migration CLI command (`loki migrate sessions --claim-to <subject>`) that assigns ownership of all unowned sessions to a specific subject. |
-| **JWT JWKS fetch failures block startup** | Medium | JWKS URL must be reachable at startup; if it's not, log an error and fall back to "reject all" mode until the fetch succeeds. A retry loop with exponential backoff runs in the background. Do NOT crash on JWKS failure. |
-| **Rate limiter DashMap growth** | Low | Per-subject windows accumulate forever without cleanup. Add a background reaper that removes entries with zero recent activity every few minutes. Cap total entries at 100k as a safety valve. |
-| **Prometheus metric cardinality explosion** | Low | `http_requests_total` with per-path labels could explode if routes have dynamic segments (`/v1/sessions/:id`). Use route templates as labels, not concrete paths. Validate label sets at registration. |
-| **Audit log retention compliance** | Low | Audit logs might need to be retained for regulatory reasons. Phase 6 provides the emission; retention is the operator's responsibility. Document this in `SECURITY.md`. |
-| **SIGHUP reload partial failure** | Medium | If the new config is invalid, don't swap it in — keep the old config running. Log the validation error. The operator can fix the file and SIGHUP again. Never leave the server in an inconsistent state. |
-| **Docker image size** | Low | `debian:bookworm-slim` is ~80 MB; final image ~100 MB. If smaller is needed, use `distroless/cc-debian12` for a ~35 MB image at the cost of not having `tini` or debugging tools. Document both options. |
-| **systemd Type=notify missing implementation** | Medium | Adding `sd_notify` requires the `sd-notify` crate AND calling it after listener bind. Missing this call makes systemd think the service failed. Add an integration test that fakes systemd and asserts the notification is sent. |
-| **Kubernetes pod disruption** | Low | HPA scales down during low traffic, but in-flight requests on the terminating pod must complete gracefully. Set `terminationGracePeriodSeconds` to at least `shutdown_grace_seconds + 10`. Document in `DEPLOYMENT.md`. |
-| **Running under a reverse proxy** | Low | CORS, `Host` header handling, `X-Forwarded-For` for rate limiter subject identification. Document the expected proxy config (trust `X-Forwarded-*` headers only from trusted proxies). |
-

-
-## What Phase 6 Does NOT Do
-
- **No multi-region replication.** Loki is a single-instance service; scale out by running multiple instances behind a load balancer, each with its own pool. Cross-instance state sharing is not in scope.
- **No database-backed session store.** `FileSessionStore` is still the only implementation. A `PostgresSessionStore` is a clean extension point (`SessionStore` trait is already there) but belongs to a follow-up.
- **No cluster coordination.** Each Loki instance is independent. Running Loki in a "cluster" mode where instances share work is a separate project.
- **No advanced ML observability.** LLM call costs, token usage trends, provider error rates — these are tracked as counters but not aggregated into dashboards. Follow-up work.
- **No built-in TLS termination.** Use a reverse proxy (nginx, Caddy, Traefik, a cloud load balancer). Supporting TLS in-process adds complexity and key management concerns that reverse proxies solve better.
- **No SAML or LDAP.** Only StaticKeys and JWT. SAML/LDAP integration can extend `AuthConfig` later.
- **No plugin system.** Extensions to auth, storage, or middleware require forking and rebuilding. A dynamic plugin loader is explicitly out of scope.
- **No multi-tenancy beyond session ownership.** Tenants share the same process, same MCP pool, same RAG cache, same resources. Strict tenant isolation (separate processes per tenant) requires orchestration outside Loki.
- **No cost accounting per tenant.** LLM API calls are tracked per-subject in audit logs but not aggregated into billing-grade cost reports.

-## v1 Release Summary
-
-After Phase 6 lands, Loki v1 has transformed from a single-user CLI tool into a production-ready multi-tenant AI service. Here's what the v1 release notes should say:
-
-**New in Loki v1:**
-
- **REST API** — full HTTP surface for completions, sessions, agents, roles, RAGs, and metadata. Streaming via Server-Sent Events, synchronous via JSON.
- **Multi-tenant sessions** — UUID-primary identity with optional human-readable aliases. Per-subject ownership with scope-based access control.
- **Concurrent safety** — per-session mutex serialization, per-MCP-server Arc sharing, per-agent runtime isolation. Run dozens of concurrent requests without corruption.
- **MCP pooling** — recently-used MCP subprocesses stay warm across requests. Near-zero warm-path latency. Configurable idle timeout and LRU cap.
- **Authentication** — static API keys or JWT with JWKS. Argon2-hashed credentials. Scope-based authorization per endpoint.
- **Observability** — Prometheus metrics, structured JSON logging with correlation IDs, dedicated audit log stream.
- **Rate limiting** — sliding-window per subject with configurable limits and burst allowance.
- **Graceful shutdown** — in-flight requests complete within a grace period; MCP subprocesses terminate cleanly; session state is persisted.
- **Deployment manifests** — Dockerfile, systemd unit, docker-compose example, Kubernetes manifests.
- **Full documentation** — runbook, deployment guide, security guide, API reference.
-
-**Backward compatibility:**
-
-CLI and REPL continue to work identically to pre-v1 builds. Existing `config.yaml`, `roles/`, `sessions/`, `agents/`, `rags/`, and `functions/` directories are read-compatible. The legacy session layout is migrated lazily on first access without destroying the old files.
-
-**What's next (v2+):**
-
- Database-backed session store for cross-instance sharing
- Native TLS termination option
- SAML / LDAP authentication extensions
- Per-tenant cost accounting and quotas
- Dynamic plugin system for custom auth, storage, and middleware
- Multi-region replication
- WebSocket transport alongside SSE

-## Phase-specific notes
-
-### Phase 1 (Steps 3-10): Config split into AppState + RequestContext
-
-Known bridge-window limitations (acceptable until Steps 9-10):
- `ReplCompleter`/`ReplPrompt` still hold `GlobalConfig`
- `Input` still holds `GlobalConfig` internally
- `eval_tool_calls` still takes `&GlobalConfig`
- Dual sync (`sync_ctx_to_config`/`sync_config_to_ctx`) required
-
-### Post-Phase 1 verification focus:
- All items above should work identically to pre-refactor behavior
- No new warnings or errors in build
- Performance should be equivalent (no observable slowdown)
