> You can't "test" comments.

I'm thinking that we're approaching a world where you can both test for comments and test the comments themselves.

Now that would be really interesting: prompt an LLM to find comments that misrepresent the code! I wonder how many false positives that would bring up?

I have a Claude Code skill for adding, deleting and improving comments. It does a decent job at detecting when comments are out of date with the code and updating them. It's not perfect, but it's something.
