# Code Cleanup Skill Scan repositories for 9 categories of technical debt (TODOs, unused imports, dead code, missing type hints, deprecated functions, naming inconsistencies, high complexity, duplicate code, missing docstrings), prioritize findings by impact/effort ratio with time estimates, and generate structured markdown reports with exact file:line references. Can apply safe auto-fixes when the user grants explicit permission. ### Examples **Focused cleanup** -- User says "Clean up the API handlers in src/api/". Read project config, scan src/api/ for all 9 categories, prioritize (5 unused imports auto-fixable, 2 stale TODOs >90d, 1 high-complexity function), present tiered report with auto-fix commands. **Broad debt scan** -- User says "What's the state of technical debt in this repo?". Identify languages and source directories, run all applicable scans, group 47 findings into Quick Wins (12), Important (8), Polish (27), generate full report with effort estimates: 2h quick wins, 6h important, 4h polish. **Auto-fix request** -- User says "Fix all the unused imports and sort them". Verify ruff/goimports available, scan for F401 and I001 violations only, report 23 unused imports across 8 files, user confirms, apply fixes, run tests, show diff. --- ## Reference Loading Table | Signal | Load These Files | Why | |---|---|---| | writing the cleanup report | `report-template.md` | Loads detailed guidance from `report-template.md`. | | running per-language scans: unused im...
