-
-            - [ ] **Check the scope of the changes** (following [Conventional Commits](https://www.conventionalcommits.org)):
-                - Are these **new APIs**? Then this is a `feat`.
-                - Are these **changes to existing APIs** that could break compatibility? Then this is a `feat!` (i.e., a breaking change).
-                - Are these **only documentation** changes to existing APIs? Then this is `docs`.
-            - [ ] Update the PR title to align with the change type (`feat`, `feat!`, or `docs`).
-            - [ ] Approve the PR once you are confident about the classification and changes made.
