I'll merge, but this seems a little complicated.

Would it make things simpler to do the rm -rf, generate the code into opensearchpy, then look at git status to see what has changed?

I'll give that approach a try. Just want to make sure files like .pycache won't cause any issues.

Anything generated should be in .gitignore.

Btw, I think it's not important what has changed. The workflow that runs this check could generate the code, then check whether anything has changed, and only if something has generate the changelog. Then try opening the PR which would do nothing if there were no changes.
