I've explicitly included instructions in my home CLAUDE.md to avoid this, because it's one of the most annoying things about how Claude writes comments.

I've also written my own package for deterministically formatting comments: https://www.npmjs.com/package/comment-fmt

Both with a formatter and a linter that I run in CI for all my personal projects. Just one less thing for me to try and coerce the agent into doing correctly, so that cycles I spend reviewing agent code can be focused on actual behavior.
