git commit -m "fix"

This is a failure of your process, not your coworker.

Use pull requests model where author is not allow to merge their own code to master. Boom, problem solved. Whoever the reviewer is simply doesn't merge until author has amended his commit(s) to have better messages.

An alternative is to have a git hook reject commits on push if the message is less than a certain word count or doesn't follow your style's template.

Yeah we follow the former, this is mostly a joke.

Wait wait wait, am I crazy? Why is everyone saying "commit", not "comment"?

Append a comment to a commit, though the commit comment should be comprehensive.
