Semantic vector search over the codebase — find code by meaning, not exact names. Use when you need to locate implementations without knowing exact function/class names. Triggers on "find code", "search codebase", "locate implementation", "what does X do".

Auto-configure AGENTS.md and brain/ knowledge docs for a new project. Use when setting up Brain Bootstrap in a new repository. Discovers the codebase, fills in templates, and writes project-specific configuration.
Use before any new feature, component, or behavioral change — when you need to explore requirements and design before writing code. Hard gate — no code until design is approved.
Build the project and verify it compiles cleanly. Use after making changes to confirm nothing is broken before running tests. Reads the build command from brain/build.md.
Activate safety mode — review every destructive command before running. Use before working on production infrastructure, migration scripts, or any task where a typo could be catastrophic.
Generate a user-facing changelog from git commits — categorize, filter noise, translate to user language. Pass a tag or date as argument (e.g. "$changelog v1.0.0" or "$changelog 2026-01-01").
Save session state before context gets full or before ending. Writes current task state, branch, and loaded docs to brain/tasks/todo.md so the next session can resume cleanly.

Finds code by meaning using local vector embeddings. No API key, works offline.

| "find code that handles rate limiting" | "who calls rateLimit()?" |

After getting results: Use the file tool on file_path at start_line–end_line for full context.
refresh_index: false for consecutive searches in the same session (no code changes)languages filter to scope search (faster for single-language queries)Index not built yet:

After major changes: Index auto-refreshes on each MCP search call (refresh_index=true default).
