+- **Linting**: Make sure your code adheres to the project’s coding standards by running `npm run lint`.
+- **Prettier**: Ensure your code is properly formatted by running `npm run check-format`.
+- **License Header**: Verify that every source file includes the correct license header as specified above.
+- **Allowed Licenses**: Ensure that any dependencies added are compliant with the list of allowed licenses (see in `package.json`). Check with `npm run check-licenses`.
+- **REUSE Compliance**: Ensure that your contributions are compliant with the [REUSE guidelines](./reuse/dep5).
+- **Tests**: Make sure all tests pass. Run `npm run test` at the root level to ensure your code didn't break other packages.
