 - Enter the dev environment with `nix develop` if you are not already inside it
 - Sync Python dependencies with `uv sync --all-groups`.
 - Run the app with `uv run repub`.
+- Run `uv run qa` often while working. It runs Tailwind CSS generation, `black`, `flake8`, `pyright`, and the full test suite in that order.
+- Run `uv run qa-final` at the end before declaring a task complete and always before staging or committing. It runs `uv run qa`, then `nix fmt`, then `nix flake check`.
 - Generate CSS with `tailwindcss -i ./repub/static/app.tailwind.css -o ./repub/static/app.css` and add `--watch` when you need live rebuilds.
 - Validate a generated feed with `./scripts/validate-feed path/to/feed.rss`. This wraps the local checkout at `~/src/github.com/w3c/feedvalidator` and pages the validator output through `less` by default.
