When & Why to Use This Skill

This Claude skill automates the integration of code quality tools into your development workflow. It streamlines the process of adding linters, formatters, and type checkers to your CI/CD pipeline, local task runners (justfile), and pre-commit hooks (lefthook), ensuring consistent code standards and reducing manual configuration errors across the project.

Use Cases

  • Integrating a new Python linter like Ruff into a project's existing GitHub Actions pipeline and local environment.
  • Setting up automated type checking with Mypy to run both locally via pre-commit hooks and during remote verification builds.
  • Ensuring consistent code formatting by adding a formatter like Black or Prettier to the project's 'just' recipes and CI verification workflows.
  • Standardizing project-wide quality gates by synchronizing local development checks with cloud-based continuous integration steps.

Adding a New Check

When adding a new code quality check (linter, formatter, type checker, etc.), update these three locations:

1. justfile

Add a new recipe and include it in the default target:

default: lint format typecheck your-check

your-check:
    uv run YOUR_COMMAND

2. .github/workflows/ci.yaml

Add a step to the verify job after the existing checks:

- name: Run YOUR_CHECK
  run: uv run YOUR_COMMAND

3. lefthook.yml

Add a job to the pre-commit.jobs list:

- name: YOUR_CHECK
  glob: "*.py"
  run: YOUR_COMMAND {staged_files}

If the tool can auto-fix issues, add stage_fixed: true.

Checklist

  • Add dev dependency to pyproject.toml if needed
  • Add justfile recipe and update default target
  • Add CI workflow step
  • Add lefthook pre-commit job
  • Run just to verify all checks pass
