This looks good 👍🏻

It might be good to have the linter run on PRs too, but this is a good first step.

I wonder if this would be better as a pre-push hook? I often make lots of WIP commits locally, and it can be annoying for the linter to run on those, since they're not intended to pass.

It used to support pre-push, but the usage for the new version has changed, and pre-push doesn't seem to work anymore 🤔 I've tried for a while and also checked if others have encountered the same issue, but no good news. Let me do more research to see if I can find a solution.

Ok, it's not a huge deal if we keep it pre-commit, especially if later on we add an action to do it on push.

I'll add it when I circle back to this PR later. I'll proceed to other higher-priority tasks at the moment, pre-push doesn't seem to work somehow on my side.

That makes sense 👍🏻 The GH action isn't a high priority.
