cartographer

Analyze a codebase and build a world-model — traces behaviors, records entities with evidence, creates boundaries by concern. Use when the user says analyze, understand, or map a codebase or specific area.

Run the self-serve verification loop — boot the current source stack against a golden fixture, assert every layer (MCP write → store → HTTP API → projection → rendered browser UI), and inspect the map visually via headless Playwright. Use when you changed Cartographer's service, store, projection, or UI and need to verify it yourself end-to-end without a human watching the browser.

Deep autonomous codebase exploration — traces behaviors end-to-end, creates boundaries by concern, builds navigable depth with sub-boundaries, enforces quality via cartographer_check_depth. Use when the user says explore, map, understand, or analyze deeply.

Visualize a pull request on the Cartographer map — see which entities are affected, the blast radius, and the review path. Use when user says "review pr", "review pull request", or "/cartographer review-pr".

Query the Cartographer world-model to answer questions about a codebase using stored evidence. Use when the user asks how something works, what calls what, or wants to understand structure.
