refactor-clean

name	refactor-clean
description	Remove dead code, duplication, and tech debt safely during the Maintain phase. Use after shipping, or when a codebase has accumulated cruft. Delegates to the harness-claude:refactor-cleaner agent. Behavior-preserving only.

/refactor-clean — safe cleanup

Goal: a leaner, more modular codebase without changing behavior.

Do this

1. Delegate to harness-claude:refactor-cleaner, or inline:
2. Find candidates with analyzers when present (knip/depcheck/ts-prune/ruff/vulture), else mgrep/graph (or Grep/Glob if those are unavailable): unused exports/imports/files, dead branches, duplicated logic, stray debug code, oversized files (>800 lines).
3. Confirm truly unused before deleting — check all references, including dynamic usage. When unsure, leave it and report.
4. Consolidate duplication into one well-named utility; split oversized files by responsibility. Small, reversible steps; run tests/build after each.

Constraints

Behavior-preserving. No feature/API changes unless asked. Keep diffs reviewable; if a cleanup turns into a redesign, stop and route to /harness-claude:architect.

Exit criterion

Cruft removed with reference checks, tests/build still green, change documented.
