For Python/FastAPI projects (uv + ruff + pytest + Pydantic v2; async route handlers, Alembic migration safety, OpenAPI contract drift): performs a structured code and documentation review using a severity-tiered findings format. Use when the user says "CR", "code review", or "perform a review" and the project is a FastAPI service. Produces a numbered findings report, waits for terse directives (fix/stet/GH), then implements and commits approved changes. Also accepts a blanket "address the findings" directive that applies them all in one pass.
