Refactor and clean up the uncommitted change before committing. Eliminate duplication, rename unclear domain concepts, collapse shotgun surgery when another similar change is likely, remove dead / test-only / redundant code, split files larger than 250 lines into cohesive modules, and confirm related tests still pass. Use after finishing a phase or sub-phase and before commit, or whenever the developer asks to clean up the current change. Triggers on: refactor change, clean up change, post-change refactor, before commit cleanup, tidy current change.
