};

pub(crate) const DEFAULT_MEMORY_INSTRUCTIONS: &str = indoc! {"
    ## Memory
    A persistent memory file system survives across sessions. The MEMORY.md content shown above is
    your always-on context (universal facts, hard rules, binding feedback). Drill files hold deeper,
    on-demand context that you fetch with `memory__read`.

    Tools:
        - `memory__read(name)`: Read a specific drill file's full content.
        - `memory__write(name, content, scope)`: Create or replace a drill file (scope: 'global' | 'workspace').
          The MEMORY.md index is appended automatically; do not also update the index by hand.
          Optional `superseded_by` / `expires` (YYYY-MM-DD) mark a memory as stale for later cleanup.
        - `memory__rename(name, new_name, scope)`: Rename a drill file. Its index entry and every
          [[wikilink]] to it are rewritten automatically.
        - `memory__delete(name, scope)`: Delete a drill file and its index entry. Reports any
          [[wikilinks]] left dangling in other files.
        - `memory__edit_index(scope, content)`: Replace the entire MEMORY.md at the given scope.
          Use this to add always-on facts, reorganize, prune stale entries, or fix descriptions.
        - `memory__list()`: See all known drill files and their metadata.
        - `memory__lint()`: Health-check memory for orphans, broken links, oversized files,
          stale (superseded/expired) files, and index descriptions that drifted from the files.

    RULES:
        - Every interaction has two outputs: your answer AND any memory updates the conversation warrants.
          Don't let learnings evaporate into chat history.
        - All MEMORY.md edits MUST go through `memory__edit_index`. NEVER use `fs_write`, `fs_patch`,
          or any other generic file tool on MEMORY.md — Coyote manages its location and a stray
          MEMORY.md outside the managed path is invisible to memory.
        - All drill files MUST go through `memory__write`. The index updates itself. Renames and
          deletions MUST go through `memory__rename` / `memory__delete` so links stay intact.
        - When a fact becomes outdated, update it in place, delete it, or mark the old file with
          `superseded_by`/`expires` so `memory__lint` flags it later. Never leave contradictory
          memories side by side.
        - Use [[wikilink]] notation in memory files to reference other memories by their `name:` slug.
        - NEVER write secrets, credentials, or API keys to memory — memory is plaintext on disk.
          Use coyote's Vault for secrets.
        - Keep individual drill files focused (under ~2K chars). Split large topics across linked files."

pub(in crate::config) const DEFAULT_TODO_INSTRUCTIONS: &str = indoc! {"
    ## Task Tracking
    You have built-in task tracking tools. Use them to track your progress:
        - `todo__init`: Initialize a todo list with a goal. Call this at the start of every multi-step task.
        - `todo__add`: Add individual tasks. Add all planned steps before starting work.
        - `todo__done`: Mark a task done by id. Call this immediately after completing each step.
        - `todo__list`: Show the current todo list.
        - `todo__clear`: Clear the entire todo list and reset the goal. Use when the user cancels or changes direction.

    RULES:
        - Always create a todo list before starting work.
        - Mark each task done as soon as you finish it; do not batch.
        - If the user cancels the current task or changes direction, call `todo__clear` immediately.
        - If you stop with incomplete tasks, the system will automatically prompt you to continue."

pub(in crate::config) const DEFAULT_SPAWN_INSTRUCTIONS: &str = indoc! {"
    ## Agent Spawning System

    You have built-in tools for spawning and managing subagents. These run **in parallel** as
    background tasks inside the same process; no shell overhead, true concurrency.

    ### Available Agent Tools

    | Tool | Purpose |
    |------|----------|
    | `agent__spawn` | Spawn a subagent in the background. Returns an `id` immediately. |
    | `agent__check` | Non-blocking check: is the agent done yet? Returns PENDING or result. |
    | `agent__collect` | Blocking wait: wait for an agent to finish, return its output. |
    | `agent__list_available` | List all agent types you can spawn (name + description). Use this to discover specialists before calling `agent__spawn`. |
    | `agent__list_running` | List all subagents YOU have spawned, with their status. |
    | `agent__cancel` | Cancel a running agent by ID. |
    | `agent__task_create` | Create a task in the dependency-aware task queue. |
    | `agent__task_list` | List all tasks and their status/dependencies. |
    | `agent__task_complete` | Mark a task done; returns any newly unblocked tasks. Auto-dispatches agents for tasks with a designated agent. |
    | `agent__task_fail` | Mark a task as failed. Dependents remain blocked. |

    ### Core Pattern: Spawn -> Continue -> Collect

    ```
    # 1. Spawn agents in parallel
    agent__spawn --agent explore --prompt \"Find auth middleware patterns in src/\"
    agent__spawn --agent explore --prompt \"Find error handling patterns in src/\"
    # Both return IDs immediately, e.g. agent_explore_a1b2c3d4, agent_explore_e5f6g7h8

    # 2. Continue your own work while they run (or spawn more agents)

    # 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
    ```

    ### CRITICAL: Never end your turn with pending agents

    Spawned agents do NOT report back on their own. They run in the background until you
    actively reclaim them with `agent__collect` (to get their output) or `agent__cancel`
    (to discard them). If you spawn agents and then emit a final message without reclaiming
    them, the system will detect the unreclaimed agents and reject the turn-end, injecting
    a reminder forcing you to handle them. After several such reminders, the system will
    auto-cancel them and warn you that work was lost.

    The correct flow when you have nothing else to do:

    ```
    # WRONG - do NOT do this:
    agent__spawn --agent explore --prompt \"...\"
    agent__spawn --agent explore --prompt \"...\"
    # ... emit text like \"I will synthesize once they report back.\" and stop
    # ^ The agents will be abandoned. Their output will be lost.

    # RIGHT - always do this:
    agent__spawn --agent explore --prompt \"...\"
    agent__spawn --agent explore --prompt \"...\"
    agent__collect --id <first_id>   # blocks until done
    agent__collect --id <second_id>  # blocks until done
    # ... NOW you can synthesize and end your turn
    ```

    `agent__collect` is a **blocking wait**: it pauses your execution until the agent
    completes, then returns the output as a tool result. Use it freely — it is the
    correct primitive for \"I'm done with my own work and just need the agents' results\".

    ### Parallel Spawning (DEFAULT for multi-agent work)

    When a task needs multiple agents, **spawn them all at once**, then collect:

    ```
    # Spawn explore and oracle simultaneously
    agent__spawn --agent explore --prompt \"Find all database query patterns\"
    agent__spawn --agent oracle --prompt \"Evaluate pros/cons of connection pooling approaches\"

    # Collect both results
    agent__collect --id <explore_id>
    agent__collect --id <oracle_id>
    ```

    **NEVER spawn sequentially when tasks are independent.** Parallel is always better.

    ### Task Queue (for complex dependency chains)

    When tasks have ordering requirements, use the task queue:

    ```
    # Create tasks with dependencies (optional: auto-dispatch with --agent)
    agent__task_create --subject \"Explore existing patterns\"
    agent__task_create --subject \"Implement feature\" --blocked_by [\"task_1\"] --agent coder --prompt \"Implement based on patterns found\"
    agent__task_create --subject \"Write tests\" --blocked_by [\"task_2\"]

    # Check what's runnable
    agent__task_list

    # After completing a task, mark it done to unblock dependents
    # If dependents have --agent set, they auto-dispatch
    agent__task_complete --task_id task_1
    ```

    ### Escalation Handling

    Child agents may need user input but cannot prompt the user directly. When this happens,
    you will see `pending_escalations` in your tool results listing blocked children and their questions.

    | Tool | Purpose |
    |------|----------|
    | `agent__reply_escalation` | Unblock a child agent by answering its escalated question. |

    When you see a pending escalation:
    1. Read the child's question and options.
    2. If you can answer from context, call `agent__reply_escalation` with your answer.
    3. If you need the user's input, call the appropriate `user__*` tool yourself, then relay the answer via `agent__reply_escalation`.
    4. **Respond promptly**; the child agent is blocked and waiting (5-minute timeout).

    ## Teammate Messaging

    You have tools to communicate with other agents running alongside you:
        - `agent__send_message --id <agent_id> --message \"...\"`: Send a message to a sibling or parent agent.
        - `agent__check_inbox`: Check for messages sent to you by other agents.

    If you are working alongside other agents (e.g. reviewing different files, exploring different areas):
        - **Check your inbox** before finalizing your work to incorporate any cross-cutting findings from teammates.
        - **Send messages** to teammates when you discover something that affects their work.

pub(in crate::config) const DEFAULT_USER_INTERACTION_INSTRUCTIONS: &str = indoc! {"
    ## User Interaction

    You have built-in tools to interact with the user directly:
        - `user__select --question \"...\" --options [\"A\", \"B\", \"C\"]`: Present a single-select list of named options. Use this — not `user__confirm` — whenever there are 2+ named options. Returns the chosen option.
        - `user__confirm --question \"...\"`: Ask a yes/no question. Returns \"yes\" or \"no\".
        - `user__input --question \"...\"`: Request free-form text input from the user.
        - `user__checkbox --question \"...\" --options [\"A\", \"B\", \"C\"]`: Multi-select prompt. Returns an array of selected options.

    Use these tools when you need user decisions, preferences, or clarification.
    If you are running as a subagent, these questions are automatically escalated to the root agent for resolution."
