impl Tool for AskAgentTool {

    type Output = AgentOutput;
    const NAME: &'static str = "ask_agent";
    const DESCRIPTION: &'static str = "Spawn a Claude subagent for discovery or deep analysis. Returns a single text response; no side effects.

Agent types:
- locator (haiku): Finds WHERE things are. Fast, shallow discovery via cli_grep/cli_glob/cli_ls. Returns file paths grouped by purpose. Cannot read file contents deeply.
- analyzer (sonnet): Explains HOW things work. Reads files, traces data flow, provides technical analysis. Must cite file:line for all claims.

Locations:
- codebase: Current repository. Paths are repo-relative.
- thoughts: Active branch documents (research/plans/artifacts). Uses thoughts_list_documents for discovery.
- references: Cloned reference repos. Paths start with references/{org}/{repo}/.
- web: Internet search. Returns URLs with quotes and source attribution.

When to use:
- Use locator when you need to find files/resources but don't yet know where they are.
- Use analyzer when you need to understand implementation details or extract specific information with citations.
- Use thoughts/references locations when the answer likely exists in existing documentation or external examples.
- Use web when you need external documentation, API references, or information not in the codebase.

When NOT to use:
- If you already know the file path, use Read directly.
- If you need a simple directory listing, use cli_ls.
- For pattern matching in known locations, use cli_grep or cli_glob.
- This tool cannot write files or make changes.

Usage notes:
- Provide clear, specific queries. The subagent is stateless and receives no prior context.
- Locator returns locations only; use analyzer or Read for content.
- Multiple ask_agent calls can run in parallel for independent queries.";
