I also maintain a popular open source repo and have seen similar. If I receive a low effort single-pass obviously-Clauded PR (many people (agents) don’t even bother using the AGENTS.md file I provide right in the repo?!) with no associated issue I also have no qualms closing. I do generally leave a short note about why I closed (volume of these is around 5/week) showing how far off they (Claude) was and encourage opening an issue where we can start a discussion which rarely happens for the drive-by folks. So I totally feel this but I find myself more disheartened by the practice than angry. It feels like slowly watching open-source go the way of email. Open and free until no-cost spam ruined the inbox for everyone...
