# Code Quality Four modes. Select by request signal: | Signal | Mode | |--------|------| | Dead code, stale TODOs, unused imports, technical debt | Cleanup | | Lint Python/JS/TS, run ruff, run biome, format code | Linting | | Python quality checks, ruff+pytest+mypy+bandit | Python Quality Gate | | Multi-language quality gate, general "quality check" | Universal Quality Gate | Default: Python-specific requests run Python Quality Gate. General requests run Universal Quality Gate. --- ## Mode A: Cleanup Scan for 9 categories of technical debt: stale TODOs, unused imports, dead code, missing type hints, deprecated functions, naming inconsistencies, high complexity, duplicate code, missing docstrings. Follow `references/code-cleanup.md` for the full 3-phase workflow (SCOPE, SCAN, REPORT). Key principles: - Read CLAUDE.md first for project conventions - Scan only what was requested; ask for a target rather than scanning everything - Exclude vendor/, node_modules/, .venv/, build/, dist/, generated/, .git/ - Prioritize findings by impact/effort: Quick Wins (auto-fixable, <5 min) > Important (bugs, security) > Polish (style) - Apply auto-fixes only with explicit user permission; check first, fix, review diff, rerun checks --- ## Mode B: Linting Check or fix Python with Ruff and JavaScript/TypeScript with Biome. Read project instructions, `pyproject.toml`, and `biome.json` first; preserve configured rules. | Task | Python | JavaScript/TypeScript | |------|--------|----------...
