In my day job, I do a lot of AI coding but almost never have Claude actually create the PR titles or descriptions for me. It produces too much content, and the justification/background sections are often not quite right.

Most PRs to me are not coming out of nowhere anyway, rather they're "here's the linked issue, I started out addressing it by doing X and Y, but then Y got hairy so I switched to Z, hope that makes sense but happy to discuss further as well."

And most feedback is not "let's have you explain the design to me in a diff comment" but rather please explain this design in a code comment so that the next reader of the source will have your context.
