 2. Make your change. Keep it focused — one logical change per PR.
 3. Run lint, type check, and tests locally before pushing:
    ```bash
-   uv run ruff check . && uv run ruff format --check .
-   uv run ty check        # type check, where ty is configured (some repos also run mypy/pyrefly)
-   # run the project's test command (often `just test` or `uv run pytest`)
+   just lint-ci           # read-only lint, format, and type checks
+   just test
    ```
+   `just lint` runs the same checks and applies fixes. The templates and `chat-app` have
+   only `just lint`. `that-depends` also runs mypy and pyrefly in both recipes.
 4. Update docs if you changed behavior or public API.
 5. Open the PR using the template. Link the issue it resolves.
