| `nr <script>`                   | Run npm script                    | `nr lint`, `nr test`                   |
| `nlx <pkg>`                     | Execute npm package (`npx`)       | `nlx tsc`                              |

## Rules

- NEVER use `npm`, `pnpm`, `yarn`, or `bun` directly unless explicitly instructed. USE the commands mentioned above.
- Prefer existing `package.json` scripts via `nr <script>` (e.g. `lint`, `typecheck`, `format`) over running tools directly with `nlx`/`npx` when available. For example, use `nr lint` instead of `nlx eslint` or `nr typecheck` instead of `nlx tsc`. Use `nlx <tool>` when `package.json` has no matching script.
