add-check

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

```just

default: lint format typecheck your-check

your-check:

uv run YOUR_COMMAND

```

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

```yaml

• name: Run YOUR_CHECK

run: uv run YOUR_COMMAND

```

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

```yaml

• name: YOUR_CHECK

glob: "*.py"

run: YOUR_COMMAND {staged_files}

```

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