I spent literally all day yesterday working on this:

sciactive.com/human-contribution-policy/

I’ve started to add it to my projects. Eventually, it will be on all of my projects. I made it so that any project could adopt it, or modify it to their needs. It’s got a thorough and clear definition of what is banned, too, so it should help any argument over pull requests.

Hopefully more projects will outright ban AI generated code (and other AI generated material).
