I'm aware of pre-commit hooks but not a big fan. I understand their purpose but it breaks my workflow when I do a git commit -p then select the files, just to then fail the hook and lose my staged files.

I think for this repo, which doesn't attract a lot of contribution anyway, just having the checks added to CI and the README is enough.
