When you need to understand this codebase, DO NOT grep and read whole files. Call the MCP tool **`retrieve_code`** (server `trl-retrieve`) with a natural-language question — it returns the exact relevant source slices (function/class/method) at a fraction of the tokens. Use **`explain_symbol`** to fetch the full source of a named symbol. Only fall back to reading whole files if retrieval returns nothing relevant.
