Code Quality Gate

A four-mode code quality skill: technical-debt cleanup, Ruff/Biome linting, a Python quality gate, and a multi-language gate.

What it does

The skill routes your request into one of four modes:

  • Cleanup — scans for 9 categories of technical debt (stale TODOs, unused imports, dead code, missing type hints, deprecated calls, naming drift, complexity, duplication, missing docstrings) and ranks findings as Quick Wins / Important / Polish.
  • Linting — Ruff for Python, Biome for JS/TS, honoring existing pyproject.toml and biome.json rules; never loosens rules just to pass.
  • Python Quality Gate — runs ruff check, ruff format --check, mypy, pytest (with coverage when configured), and bandit in order, continuing past failures and reporting file:line diagnostics.
  • Universal Quality Gate — detects Python, Go, JavaScript, TypeScript, Rust and Shell via marker files and runs each language's tools, with --staged, --lang, --fix and -v options.

Auto-fixes are applied only with explicit permission, followed by a git diff review and a re-run.

Who it's for

  • Python or JS/TS developers who want a repeatable pre-commit quality check.
  • Teams running polyglot monorepos that need one consistent gate.
  • Anyone inheriting a legacy codebase and needing a prioritized debt map.

Example uses

  1. "Find dead code and stale TODOs in src/" → Cleanup mode scopes the scan and emits a categorized report.
  2. "Run the Python quality gate before I commit" → ruff, format, mypy, pytest, bandit run in sequence with prioritized findings.
  3. "Lint only my staged files" → run_quality_gate.py --staged detects languages of changed files and runs the matching tools.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/code-quality/code-quality folder from the GitHub repo notque/vexjoy-agent into my ~/.claude/skills/code-quality/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/notque/vexjoy-agent.git /tmp/vexjoy-agent && mkdir -p ~/.claude/skills && cp -r /tmp/vexjoy-agent/skills/code-quality/code-quality ~/.claude/skills/code-quality

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and clone the repo: git clone https://github.com/notque/vexjoy-agent.git
  2. Create the skills directory: mkdir -p ~/.claude/skills
  3. Copy the skill: cp -r vexjoy-agent/skills/code-quality/code-quality ~/.claude/skills/code-quality
  4. Verify the bundled references/ folder and universal-quality-gate/scripts/run_quality_gate.py came along: ls -R ~/.claude/skills/code-quality
  5. Install the underlying tools: pip install ruff pytest mypy bandit (Python) and make sure Node.js is available for npx @biomejs/biome.
  6. Restart Claude Code and try a prompt like "run the python quality gate on this repo".
