Since you are skipping the hook in ci, then you could use the simpler form without the git processing.

Would you mind keeping it? That way, I can test it locally for a while before making it mandatory with pre-commit-ci.

From several discussions:

• Automation would be too intrusive. Rather default opt-out instead of opt-in.
• Script that does this is helpful if it is done consciously (with tracking of the diff)
• Maybe something like a button

Closing this as it's unlikely that this feature will be pursued further. The current approach is to use an item on the task list in the PR template to ensure consistency.
