looks good

Did you try on your forked repo to open a PR and have this linter run?

I assume also that when it gets run there will be some errors due to these style: "consistent" restrictions. Ideally these get fixed in the same PR (or a PR right after) as adding the linter so that follow-up PRs do not fail for the wrong reasons.

I think we can just use actions/checkout@v4 here, not sure why EIPs repo uses that specific revision.

I did run it, though locally with act and there was no error.

Should I use version here too instead of the revision?

I did run the ci check on my forked repo as suggested, it failed against files not meeting the rules outlined in the config file, which I think is working as expected.

The shown error is strange though, I would not expect the line length to be checked considering this snippet from the used config:

# MD013/line-length - Line length
# Changed from default so we can allow the paragraphs to be a single line
MD013: false
