Example queries — "clean up the whole codebase", "run a full code-quality pass", "sweep this repo", "do all the cleanups in order".
Find and remove deprecated, legacy, and fallback code paths with zero callers. Verifies callers via repo grep + LSP before deletion. Removes unreachable fallback branches. Use when the user asks to remove deprecated code, clean up legacy paths, drop fallbacks, or simplify code branches. Example queries — "remove the deprecated API", "drop the v1 fallback", "this code is marked legacy, kill it", "simplify these branches".
