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
