About

Investigate why code exists before changing it. Trace call sites, history, and intent; map keep/move/replace/delete options with risks; recommend one; stop without editing unless explicitly asked. Use when the user asks why something exists, what it does, whether it can be removed/replaced/cleaned up, if something is low-hanging fruit, or where a type/helper/path is used — not when implementing a known ticket, verifying review findings, or running a forward-looking feature spike.

Use cases: writing
