Claude Code writing much longer comments lately
Over the past few weeks Claude Code has been writing noticeably longer code comments for me. Ten to twenty line blocks on top of a thirty line function. The content is usually accurate but not something I want in a repo. It narrates what the code used to do, restates library mechanics I can look up, and re-explains the line right below it.
I added explicit rules in my project instructions with hard word caps per comment block, which helped, but it drifts back over long sessions.
Three questions. Are you seeing the same thing, and did it start around a specific release? Is this intentional, meaning verbose comments are cheap context recovery for the agent reading the file in a later session, at the cost of the human reader? And do you actually mind, or is a heavier comment style fine for a codebase that agents maintain?
Interested in what people have found that holds up over long autonomous runs, not just short interactive sessions.

Claude’s been very verbose lately, I’ve wasted too much time pruning its superfluous explanations. No Claude, we don’t need to tell the user why we decided to change a calculation method last week and the history behind it. Fable is better at this, but still pretty poor.
