+# Phase 1 QA — Test Implementation Plan
+
+## Purpose
+
+Verify that all existing Loki behaviors are preserved after the
+Phase 1 refactoring (Config god-state → AppState + RequestContext
+split). Tests should validate behavior, not implementation details,
+unless a specific implementation pattern is fragile and needs
+regression protection.
+
+## Reference codebases
+
+- **Old code**: `~/code/testing/loki` (branch: `develop`)
+- **New code**: `~/code/loki` (branch: working branch with Phase 1)
+
+## Process (per iteration)
+
+1. Read the previous iteration's test implementation notes (if any)
+2. Read the test plan file for the current feature area
+3. Read the old code to identify the logic that creates those flows
+4. While reading old code:
+   - Note additional behaviors not in the plan file → update the file
+   - Note feature overlaps / context-switching scenarios → add tests
+5. Create unit/integration tests in the new code
+6. Ensure all tests pass
+7. Write test implementation notes for the iteration
+8. Pause for user approval before proceeding to next iteration
+
+## Test philosophy
+
+- **Behavior over implementation**: Test what the system DOES, not
+  HOW it does it internally
+- **Exception**: If implementation logic is fragile and a slight
+  change would break Loki, add an implementation-specific test
+- **No business logic changes**: Only modify non-test code if a
+  genuine bug is discovered (old behavior missing in new code)
+- **Context switching**: Pay special attention to state transitions
+  (role→agent, MCP-enabled→disabled, etc.)
+
+## Test location
+
+All new tests go in `tests/` directory as integration tests, or
+inline as `#[cfg(test)] mod tests` in the relevant source file,
+depending on what's being tested:
+
+- **Unit tests** (pure logic, no I/O): inline in source file
+- **Integration tests** (multi-module, state transitions): `tests/`
+- **Behavior tests** (config parsing, tool resolution): can be either
+
+## Feature areas (test plan files)
+
+Each feature area has a plan file in `docs/testing/plans/`. The
+files are numbered for execution order (dependencies first):
+
+| # | File | Feature area | Priority |
+|---|---|---|---|
+| 01 | `01-config-and-appconfig.md` | Config loading, AppConfig fields, defaults | High |
+| 02 | `02-roles.md` | Role loading, retrieval, role-likes, temp roles | High |
+| 03 | `03-sessions.md` | Session create/load/save, compression, autoname | High |
+| 04 | `04-agents.md` | Agent init, tool compilation, variables, lifecycle | Critical |
+| 05 | `05-mcp-lifecycle.md` | MCP server start/stop, factory, runtime, scope transitions | Critical |
+| 06 | `06-tool-evaluation.md` | eval_tool_calls, ToolCall dispatch, tool handlers | Critical |
+| 07 | `07-input-construction.md` | Input::from_str, from_files, field capturing, function selection | High |
+| 08 | `08-request-context.md` | RequestContext methods, scope transitions, state management | Critical |
+| 09 | `09-repl-commands.md` | REPL command handlers, state assertions, argument parsing | High |
+| 10 | `10-cli-flags.md` | CLI argument handling, mode switching, early exits | High |
+| 11 | `11-sub-agent-spawning.md` | Supervisor, child agents, escalation, messaging | Critical |
+| 12 | `12-rag.md` | RAG init/load/search, embeddings, document management | Medium |
+| 13 | `13-completions-and-prompt.md` | Tab completion, prompt rendering, highlighter | Medium |
+| 14 | `14-macros.md` | Macro loading, execution, variable interpolation | Medium |
+| 15 | `15-vault.md` | Secret management, interpolation in MCP config | Medium |
+| 16 | `16-functions-and-tools.md` | Function declarations, tool compilation, binaries | High |
+
+## Iteration tracking
+
+Each completed iteration produces a notes file at:
+`docs/testing/notes/ITERATION-<N>-NOTES.md`
+
+These notes contain:
+- Which plan file(s) were addressed
+- Tests created (file paths, test names)
+- Bugs discovered (if any)
+- Observations for future iterations
+- Updates made to other plan files
+
+## Intentional improvements (NEW ≠ OLD)
+
+These are behavioral changes that are intentional and should NOT
+be tested for old-code parity:
+
+| # | What | Old | New |
+|---|---|---|---|
+| 1 | Agent list hides `.shared` | Shown | Hidden |
+| 2 | Tool file priority | Filesystem order | .sh > .py > .ts > .js |
+| 3 | MCP disabled + agent | Warning, continues | Error, blocks |
+| 4 | Role MCP warning | Always when mcp_support=false | Only when role has MCP |
+| 5 | Enabled tools completions | Shows internal tools | Hides user__/mcp_/todo__/agent__ |
+| 6 | MCP server completions | Only aliases | Configured servers + aliases |
+
+## How to pick up in a new session
+
+If context is lost (new chat session):
+
+1. Read this file first
+2. Read the latest `docs/testing/notes/ITERATION-<N>-NOTES.md`
+3. That file tells you which plan file to work on next
+4. Read that plan file
+5. Follow the process above

+
+**Total: 10 new tests (59 → 69)**
+
+## Bugs discovered
+
+None. The `save` default was `false` in both old and new code
+(my plan file incorrectly said `true` — corrected).
+
+## Observations for future iterations
+
+1. The `Config::default().save` is `false`, but the plan file
+   01 incorrectly listed it as `true`. Plan file should be
+   updated to reflect the actual default.
+
+2. `AppConfig::default()` doesn't exist natively (no derive).
+   Tests construct it via `Config::default().to_app_config()`.
+   This is fine since that's how it's created in production.
+
+3. The `visible_tools` field computation happens during
+   `Config::init` (not `to_app_config`). Testing the full
+   visible_tools resolution requires integration-level testing
+   with actual tool files. Deferred to plan file 16
+   (functions-and-tools).
+
+4. Testing `Config::init` directly is difficult because it reads
+   from the filesystem, starts MCP servers, etc. The unit tests
+   focus on the conversion paths which are the Phase 1 surface.

+**Total: 17 new tests (69 → 86)**
+
+## Bugs discovered
+
+None. Role parsing behavior matches between old and new code.
+
+## Observations for future iterations
+
+1. `retrieve_role` (which calls `Model::retrieve_model`) can't be
+   easily unit-tested without a real client config. It depends on
+   having at least one configured client. Deferred to integration
+   testing or plan 08 (RequestContext scope transitions).
+
+2. The `use_role` async method (which calls `rebuild_tool_scope`)
+   requires async test runtime and MCP infrastructure. Deferred to
+   plan 05 (MCP lifecycle) and 08 (RequestContext).
+
+3. `use_role_obj` correctly rejects when agent is active — tested
+   implicitly through the error path, but creating a mock Agent
+   is complex. Noted for plan 04 (agents).
+
+4. The `extract_role` priority order (session > agent > role > default)
+   is important behavioral contract. Tests verify the role and
+   default cases. Session and agent cases deferred to plans 03, 04.
+
+5. Added `create_test_ctx()` helper to request_context.rs tests.
+   Future iterations should reuse this.

+
+## Bugs discovered
+
+None. Session behavior matches between old and new code.
+
+## Observations for future iterations
+
+1. `Session::new_from_ctx` and `Session::load_from_ctx` have
+   `#[allow(dead_code)]` annotations — they were bridge methods.
+   Should verify if they're still needed or if the old `Session::new`
+   and `Session::load` (which take `&Config`) should be cleaned up
+   in a future pass.
+
+2. The `compress` method moves messages to `compressed_messages` and
+   adds a single system message with the summary. This is a critical
+   behavioral contract — if the summary format changes, sessions
+   could break.
+
+3. `needs_compression` uses `self.compression_threshold` (session-
+   level) with fallback to the global threshold. This priority
+   (session > global) is important behavior.
+
+4. Session carry-over (the "incorporate last Q&A?" prompt) happens
+   inside `use_session` which is async and involves user interaction
+   (inquire::Confirm). Can't unit test this — needs integration test
+   or manual verification.
+
+5. The `extract_role` test for session-active case should verify that
+   `session.to_role()` is returned. Added note to plan 02.

+
+1. `Agent::init` can't be unit tested easily — requires agent config

+   would be needed for full coverage.
+
+2. AgentConfig default values verified:
+   - `max_concurrent_agents` = 4
+   - `max_agent_depth` = 3
+   - `max_auto_continues` = 10
+   - `inject_todo_instructions` = true
+   - `inject_spawn_instructions` = true
+   These are important behavioral contracts.
+
+3. The `exit_agent` test shows that clearing agent state also
+   rebuilds the tool_scope with fresh functions. This is the
+   correct behavior for returning to the global context.
+
+4. Agent variable interpolation (special vars like __os__, __cwd__)
+   happens in Agent::init which is filesystem-dependent. Deferred.

+# Test Plan: Config Loading and AppConfig
+
+## Feature description
+
+Loki loads its configuration from a YAML file (`config.yaml`) into
+a `Config` struct, then converts it to `AppConfig` (immutable,
+shared) + `RequestContext` (mutable, per-request). The `AppConfig`
+holds all serialized fields; `RequestContext` holds runtime state.
+
+## Behaviors to test
+
+### Config loading
+- [ ] Config loads from YAML file with all supported fields
+- [x] Missing optional fields get correct defaults (config_defaults_match_expected)
+- [ ] `model_id` defaults to first available model if empty (requires Config::init, integration test)
+- [x] `temperature`, `top_p` default to `None`
+- [x] `stream` defaults to `true`
+- [x] `save` defaults to `false` (CORRECTED: was listed as true)
+- [x] `highlight` defaults to `true`
+- [x] `dry_run` defaults to `false`
+- [x] `function_calling_support` defaults to `true`
+- [x] `mcp_server_support` defaults to `true`
+- [x] `compression_threshold` defaults to `4000`
+- [ ] `document_loaders` populated from config and defaults (requires Config::init)
+- [x] `clients` parsed from config (to_app_config_copies_clients)
+
+### AppConfig conversion
+- [x] `to_app_config()` copies all serialized fields correctly
+- [x] `clients` field populated on AppConfig
+- [ ] `visible_tools` correctly computed from `enabled_tools` config (deferred to plan 16)
+- [x] `mapping_tools` correctly parsed
+- [x] `mapping_mcp_servers` correctly parsed
+- [ ] `user_agent` resolved (auto → crate name/version)
+
+### RequestContext conversion
+- [x] `to_request_context()` copies all runtime fields (to_request_context_creates_clean_state)
+- [ ] `model` field populated with resolved model (requires Model::retrieve_model)
+- [ ] `working_mode` set correctly (Repl vs Cmd)
+- [x] `tool_scope` starts with default (empty)
+- [x] `agent_runtime` starts as `None`
+
+### AppConfig field accessors
+- [x] `editor()` returns configured editor or $EDITOR
+- [x] `light_theme()` returns theme flag
+- [ ] `render_options()` returns options for markdown rendering
+- [x] `sync_models_url()` returns configured or default URL
+
+### Dynamic config updates
+- [x] `update_app_config` closure correctly clones and replaces Arc
+- [x] Changes to `dry_run`, `stream`, `save` persist across calls
+- [x] Changes visible to subsequent `ctx.app.config` reads
+
+## Context switching scenarios
+- [ ] AppConfig remains immutable after construction (no field mutation)
+- [ ] Multiple RequestContexts can share the same AppState
+- [ ] Changing AppConfig fields (via clone-mutate-replace) doesn't
+      affect other references to the old Arc
+
+## Old code reference
+- `src/config/mod.rs` — `Config` struct, `Config::init`, defaults
+- `src/config/bridge.rs` — `to_app_config`, `to_request_context`
+- `src/config/app_config.rs` — `AppConfig` struct and methods

+# Test Plan: Roles
+
+## Feature description
+
+Roles define a system prompt + optional model/temperature/MCP config
+that customizes LLM behavior. Roles can be built-in or user-defined
+(markdown files). Roles are "role-likes" — sessions and agents also
+implement the RoleLike trait.
+
+## Behaviors to test
+
+### Role loading
+- [x] Built-in roles load correctly (shell, code)
+- [ ] User-defined roles load from markdown files (requires filesystem)
+- [x] Role parses model_id from metadata
+- [x] Role parses temperature, top_p from metadata
+- [x] Role parses enabled_tools from metadata
+- [x] Role parses enabled_mcp_servers from metadata
+- [ ] Role with no model_id inherits current model (requires retrieve_role + client config)
+- [ ] Role with no temperature inherits from AppConfig (requires retrieve_role)
+- [ ] Role with no top_p inherits from AppConfig (requires retrieve_role)
+
+### retrieve_role
+- [ ] Retrieves by name from file system
+- [ ] Resolves model via Model::retrieve_model
+- [ ] Falls back to current model if role has no model_id
+- [ ] Sets temperature/top_p from AppConfig when role doesn't specify
+
+### use_role (scope transition)
+- [x] Sets role on RequestContext (use_role_obj_sets_role)
+- [ ] Triggers rebuild_tool_scope (async, deferred to plan 05/08)
+- [ ] MCP servers start if role has enabled_mcp_servers (deferred to plan 05)
+- [ ] MCP meta functions added to function list (deferred to plan 05)
+- [ ] Previous role cleared when switching (deferred to plan 08)
+- [x] Role-like temperature/top_p take effect (role_set_temperature_works)
+
+### exit_role
+- [x] Clears role from RequestContext (exit_role_clears_role)
+- [ ] Followed by bootstrap_tools to restore global tool scope (async, deferred)
+- [ ] MCP servers from role are stopped (deferred to plan 05)
+- [ ] Global MCP servers restored (deferred to plan 05)
+
+### use_prompt (temp role)
+- [x] Creates a TEMP_ROLE_NAME role with the prompt text (use_prompt_creates_temp_role)
+- [x] Uses current model
+- [x] Activates via use_role_obj
+
+### extract_role
+- [ ] Returns role from agent if agent active (deferred to plan 04)
+- [ ] Returns role from session if session active with role (deferred to plan 03)
+- [x] Returns standalone role if active (extract_role_returns_standalone_role)
+- [x] Returns default role if none active (extract_role_returns_default_when_nothing_active)
+
+### One-shot role messages (REPL)
+- [ ] `.role coder write hello` sends message with role, then exits role
+- [ ] Original state restored after one-shot
+
+## Context switching scenarios
+- [ ] Role → different role: old role replaced, MCP swapped
+- [ ] Role → session: role cleared, session takes over
+- [ ] Role with MCP → exit: MCP servers stop, global MCP restored
+- [ ] No MCP → role with MCP: servers start
+- [ ] Role with MCP → role without MCP: servers stop

+# Test Plan: Sessions
+
+## Feature description
+
+Sessions persist conversation history across multiple turns. They
+store messages, role context, model info, and optional MCP config.
+Sessions can be temporary, named, or auto-named.
+
+## Behaviors to test
+
+### Session creation
+- [ ] Temp session created with TEMP_SESSION_NAME
+- [ ] Named session created at correct file path
+- [ ] New session captures current role via extract_role
+- [ ] New session captures save_session from AppConfig
+- [ ] Session tracks model_id
+
+### Session loading
+- [ ] Named session loads from YAML file
+- [ ] Loaded session resolves model via Model::retrieve_model
+- [ ] Loaded session restores role_prompt if role exists
+- [ ] Auto-named sessions (prefixed `_/`) handled correctly
+
+### Session saving
+- [ ] Session saved to correct path
+- [ ] Session file contains messages, model_id, role info
+- [ ] save_session flag controls whether session is persisted
+- [ ] set_save_session_this_time overrides for current turn
+
+### Session lifecycle
+- [ ] use_session creates or loads session
+- [ ] Already in session → error
+- [ ] exit_session saves and clears
+- [ ] empty_session clears messages but keeps session active
+
+### Session carry-over
+- [ ] New empty session with last_message prompts "incorporate?"
+- [ ] If accepted, last Q&A added to session
+- [ ] If declined, session starts fresh
+- [ ] Only prompts when continuous and output not empty
+
+### Session compression
+- [ ] maybe_compress_session returns true when threshold exceeded
+- [ ] compress_session reduces message count
+- [ ] Compression message shown to user
+- [ ] Session usable after compression
+
+### Session autoname
+- [ ] maybe_autoname_session returns true for new sessions
+- [ ] Auto-naming sets session name based on content
+- [ ] Autoname only triggers once per session
+
+### Session info
+- [ ] session_info returns formatted session details
+- [ ] Shows message count, model, role, tokens
+
+## Context switching scenarios
+- [ ] Session → role change: role updated within session
+- [ ] Session → exit session: messages saved, state cleared
+- [ ] Agent session → exit: agent session cleanup
+- [ ] Session with MCP → exit: MCP servers handled
+
+## Old code reference
+- `src/config/mod.rs` — `use_session`, `exit_session`, `empty_session`

+# Test Plan: Agents
+
+## Feature description
+
+Agents combine a role (instructions), tools (bash/python/ts scripts),
+optional RAG, optional MCP servers, and optional sub-agent spawning
+capability. Agent::init compiles tools, resolves model, loads RAG,
+and sets up the agent environment.
+
+## Behaviors to test
+
+### Agent initialization
+- [ ] Agent::init loads config.yaml from agent directory
+- [ ] Agent tools compiled from tools.sh / tools.py / tools.ts
+- [ ] Tool file priority: .sh > .py > .ts > .js
+- [ ] Global tools loaded (from global_tools config)
+- [ ] Model resolved from agent config or defaults to current
+- [ ] Agent with no model_id uses current model
+- [ ] Temperature/top_p from agent config applied
+- [ ] Dynamic instructions (_instructions function) invoked if configured
+- [ ] Static instructions loaded from config
+- [ ] Agent variables interpolated into instructions
+- [ ] Special variables (__os__, __cwd__, __now__, etc.) interpolated
+- [ ] Agent .env file loaded if present
+- [ ] Built-in agents installed on first run (skip if exists)
+
+### Agent tools
+- [ ] Agent-specific tools available as function declarations
+- [ ] Global tools (from global_tools) also available
+- [ ] Tool binaries built in agent bin directory
+- [ ] clear_agent_bin_dir removes old binaries before rebuild
+- [ ] Tool declarations include name, description, parameters
+
+### Agent with MCP
+- [ ] MCP servers listed in agent config started
+- [ ] MCP meta functions (invoke/search/describe) added
+- [ ] Agent with MCP but mcp_server_support=false → error
+- [ ] MCP servers stopped on agent exit
+
+### Agent with RAG
+- [ ] RAG documents loaded from agent config
+- [ ] RAG available during agent conversation
+- [ ] RAG search results included in context
+
+### Agent sessions
+- [ ] Agent session started (temp or named)
+- [ ] agent_session config used if no explicit session
+- [ ] Agent session variables initialized
+
+### Agent lifecycle
+- [ ] use_agent checks function_calling_support
+- [ ] use_agent errors if agent already active
+- [ ] exit_agent clears agent, session, rag, supervisor
+- [ ] exit_agent restores global tool scope
+
+### Auto-continuation
+- [ ] Agents with auto_continue=true continue after incomplete todos
+- [ ] max_auto_continues limits continuation attempts
+- [ ] Continuation prompt sent with todo state
+- [ ] clear todo stops continuation
+
+### Conversation starters
+- [ ] Starters loaded from agent config
+- [ ] .starter lists available starters
+- [ ] .starter <n> sends the starter as a message
+
+## Context switching scenarios
+- [ ] Agent → exit: tools cleared, MCP stopped, session ended
+- [ ] Agent with MCP → exit: MCP servers released, global MCP restored
+- [ ] Already in agent → start agent: error
+- [ ] Agent with RAG → exit: RAG cleared

+# Test Plan: MCP Server Lifecycle
+
+## Feature description
+
+MCP (Model Context Protocol) servers are external tools that run
+as subprocesses communicating via stdio. Loki manages their lifecycle
+through McpFactory (start/share via Weak dedup) and McpRuntime
+(per-scope active server handles). Servers are started/stopped
+during scope transitions (role/session/agent enter/exit).
+
+## Behaviors to test
+
+### MCP config loading
+- [ ] mcp.json parsed correctly from functions directory
+- [ ] Server specs include command, args, env, cwd
+- [ ] Vault secrets interpolated in mcp.json
+- [ ] Missing secrets reported as warnings
+- [ ] McpServersConfig stored on AppState.mcp_config
+
+### McpFactory
+- [ ] acquire() spawns new server when none active
+- [ ] acquire() returns existing handle via Weak upgrade
+- [ ] acquire() spawns fresh when Weak is dead
+- [ ] Multiple acquire() calls for same spec share handle
+- [ ] Different specs get different handles
+- [ ] McpServerKey built correctly from spec (sorted args/env)
+
+### McpRuntime
+- [ ] insert() adds server handle by name
+- [ ] get() retrieves handle by name
+- [ ] server_names() returns all active names
+- [ ] is_empty() correct for empty/non-empty
+- [ ] search() finds tools by keyword (BM25 ranking)
+- [ ] describe() returns tool input schema
+- [ ] invoke() calls tool on server and returns result
+
+### spawn_mcp_server
+- [ ] Builds Command from spec (command, args, env, cwd)
+- [ ] Creates TokioChildProcess transport
+- [ ] Completes rmcp handshake (serve)
+- [ ] Returns Arc<ConnectedServer>
+- [ ] Log file created when log_path provided
+
+### rebuild_tool_scope (MCP integration)
+- [ ] Empty enabled_mcp_servers → no servers acquired
+- [ ] "all" → all configured servers acquired
+- [ ] Comma-separated list → only listed servers acquired
+- [ ] Mapping resolution: alias → actual server key(s)
+- [ ] MCP meta functions appended for each started server
+- [ ] Old ToolScope dropped (releasing old server handles)
+- [ ] Loading spinner shown during acquisition
+- [ ] AbortSignal properly threaded through
+
+### Server lifecycle during scope transitions
+- [ ] Enter role with MCP: servers start
+- [ ] Exit role: servers stop (handle dropped)
+- [ ] Enter role A (MCP-X) → exit → enter role B (MCP-Y):
+      X stops, Y starts
+- [ ] Enter role with MCP → exit to no MCP: servers stop,
+      global MCP restored
+- [ ] Start REPL with global MCP → enter agent with different MCP:
+      agent MCP takes over
+- [ ] Exit agent: agent MCP stops, global MCP restored
+
+### MCP tool invocation chain
+- [ ] LLM calls mcp__search_<server> → search results returned
+- [ ] LLM calls mcp__describe_<server> tool_name → schema returned
+- [ ] LLM calls mcp__invoke_<server> tool args → tool executed
+- [ ] Server not found → "MCP server not found in runtime" error
+- [ ] Tool not found → appropriate error
+
+### MCP support flag
+- [ ] mcp_server_support=false → no MCP servers started
+- [ ] mcp_server_support=false + agent with MCP → error (blocks)
+- [ ] mcp_server_support=false + role with MCP → warning, continues
+- [ ] .set mcp_server_support true → MCP servers start
+
+### MCP in child agents
+- [ ] Child agent MCP servers acquired via factory
+- [ ] Child agent MCP runtime populated
+- [ ] Child agent MCP tool invocations work
+- [ ] Child agent exit drops MCP handles
+
+## Context switching scenarios (comprehensive)
+- [ ] No MCP → role with MCP → exit role → no MCP
+- [ ] Global MCP-A → role MCP-B → exit role → global MCP-A
+- [ ] Global MCP-A → agent MCP-B → exit agent → global MCP-A
+- [ ] Role MCP-A → session MCP-B (overrides) → exit session
+- [ ] Agent MCP → child agent MCP → child exits → parent MCP intact
+- [ ] .set enabled_mcp_servers X → .set enabled_mcp_servers Y:
+      X released, Y acquired
+- [ ] .set enabled_mcp_servers null → all released

+# Test Plan: Tool Evaluation
+
+## Feature description
+
+When the LLM returns tool calls, `eval_tool_calls` dispatches each
+call to the appropriate handler. Handlers include: shell tools
+(bash/python/ts scripts), MCP tools, supervisor tools (agent spawn),
+todo tools, and user interaction tools.
+
+## Behaviors to test
+
+### eval_tool_calls dispatch
+- [ ] Calls dispatched to correct handler by function name prefix
+- [ ] Tool results returned for each call
+- [ ] Multiple concurrent tool calls processed
+- [ ] Tool call tracker updated (chain length, repeats)
+- [ ] Root agent (depth 0) checks escalation queue after eval
+- [ ] Escalation notifications injected into results
+
+### ToolCall::eval routing
+- [ ] agent__* → handle_supervisor_tool
+- [ ] todo__* → handle_todo_tool
+- [ ] user__* → handle_user_tool (depth 0) or escalate (depth > 0)
+- [ ] mcp_invoke_* → invoke_mcp_tool
+- [ ] mcp_search_* → search_mcp_tools
+- [ ] mcp_describe_* → describe_mcp_tool
+- [ ] Other → shell tool execution
+
+### Shell tool execution
+- [ ] Tool binary found and executed
+- [ ] Arguments passed correctly
+- [ ] Environment variables set (LLM_OUTPUT, etc.)
+- [ ] Tool output returned as result
+- [ ] Tool failure → error returned as tool result (not panic)
+
+### Tool call tracking
+- [ ] Tracker counts consecutive identical calls
+- [ ] Max repeats triggers warning
+- [ ] Chain length tracked across turns
+- [ ] Tracker state preserved across tool-result loops
+
+### Function selection
+- [ ] select_functions filters by role's enabled_tools
+- [ ] select_functions includes MCP meta functions for enabled servers
+- [ ] select_functions includes agent functions when agent active
+- [ ] "all" enables all functions
+- [ ] Comma-separated list enables specific functions
+
+## Context switching scenarios
+- [ ] Tool calls during agent → agent tools available
+- [ ] Tool calls during role → role tools available
+- [ ] Tool calls with MCP → MCP invoke/search/describe work
+- [ ] No agent → no agent__/todo__ tools in declarations

+- [ ] build_messages() uses captured session
+- [ ] echo_messages() uses captured session
+- [ ] set_regenerate(role) refreshes role
+- [ ] use_embeddings() searches RAG if present
+- [ ] merge_tool_results() creates continuation input
+
+## Context switching scenarios

+# Test Plan: RequestContext
+
+## Feature description
+
+`RequestContext` is the per-request mutable state container. It holds

+- [ ] Accessor methods (current_depth, supervisor, inbox, etc.) return
+      correct values when agent active
+- [ ] Accessor methods return defaults when no agent
+
+### Settings update
+- [ ] update() handles all .set keys correctly
+- [ ] update_app_config() clones and replaces Arc properly
+- [ ] delete() handles all delete subcommands
+
+### Session helpers
+- [ ] list_sessions() returns session names
+- [ ] list_autoname_sessions() returns auto-named sessions
+- [ ] session_file() returns correct path

+# Test Plan: REPL Commands
+
+## Feature description
+
+The REPL processes dot-commands (`.role`, `.session`, `.agent`, etc.)
+and plain text (chat messages). Each command has state assertions
+(e.g., `.info role` requires an active role).
+
+## Behaviors to test
+
+### Command parsing
+- [ ] Dot-commands parsed correctly (command + args)

+# Test Plan: Sub-Agent Spawning
+
+## Feature description
+
+Agents with can_spawn_agents=true can spawn child agents that run
+in parallel as background tokio tasks. Children communicate results
+back to the parent via collect/check. Escalation allows children
+to request user input through the parent.
+
+## Behaviors to test
+
+### Spawn
+- [ ] agent__spawn creates child agent in background
+- [ ] Child gets own RequestContext with incremented depth
+- [ ] Child gets own session, model, functions
+- [ ] Child gets shared root_escalation_queue
+- [ ] Child gets inbox for teammate messaging
+- [ ] Child MCP servers acquired if configured
+- [ ] Max concurrent agents enforced
+- [ ] Max depth enforced
+- [ ] Agent not found → error
+- [ ] can_spawn_agents=false → no spawn tools available
+
+### Collect/Check
+- [ ] agent__check returns PENDING or result
+- [ ] agent__collect blocks until done, returns output
+- [ ] Output summarization when exceeds threshold
+- [ ] Summarization uses configured model
+
+### Task queue
+- [ ] agent__task_create creates tasks with dependencies
+- [ ] agent__task_complete marks done, unblocks dependents
+- [ ] Auto-dispatch spawns agent for unblocked tasks
+- [ ] agent__task_list shows all tasks with status
+
+### Escalation
+- [ ] Child calls user__ask → escalation created
+- [ ] Parent sees pending_escalations notification
+- [ ] agent__reply_escalation unblocks child
+- [ ] Escalation timeout → fallback message
+
+### Teammate messaging
+- [ ] agent__send_message delivers to sibling inbox
+- [ ] agent__check_inbox drains messages
+
+### Child agent lifecycle
+- [ ] run_child_agent loops: create input → call completions → process results
+- [ ] Child uses before/after_chat_completion
+- [ ] Child tool calls evaluated via eval_tool_calls
+- [ ] Child exits cleanly, supervisor cancels on completion
+
+## Context switching scenarios
+- [ ] Parent spawns child with MCP → child MCP works independently
+- [ ] Parent exits agent → all children cancelled
+- [ ] Multiple children share escalation queue correctly
