I noticed a few repositories use something like this:

https://github.com/rudderlabs/github-action-check-pr-title

This one seems popular
https://github.com/amannn/action-semantic-pull-request

To check for conventional commit standards in our pr titles. This could be useful as a reminder to fix pr titles before we merge. It's an easy fix, but also a very easy thing to forget when creating a new pr!! (I wouldn't mind the reminder).
