Nothing. And that's the problem -- the issue isn't "should a contributor be able to use AI" it's quickly becoming "is this entire contributor an AI agent". Every actual-human who gets a bad first experience hurts the project. The contributors having to be suspicious of new people hurts the project. The whole thing just sucks, and I don't know how to fix it.

I use claude-code, but the AI ecosystem and some of the autonomous tooling coming out of it -- which some people "helpfully" use irresponsibly and point at OSS projects they aren't personally invested in -- enables a LARGE amount of abusive behavior towards open source projects. This is even before we get into how many infrastructural resources crawlers eat up.

Me, and most other OSS contributors, signed up to be a mentor, to create software, to work together ... not to be the equivalent of a reddit moderator banning AI agents left and right.
