Seems like there's a need for github to create a separate flow for AI-cretaed PRs. Project maintainers should be able to stipulate rules like this in English, and an AI "pre-reviewer" would check that the AI has followed all these rules before the PR is created, and chat with the AI submitter to resolve any violations. For exceptional cases, a human submitter is required.

Granted, the compute required is probably more expensive than github would offer for free, and IDK whether it'd be within budget for many open-source projects.

Also granted, something like this may be useful for human-sourced PRs as well, though perhaps post-submission so that maintainers can see and provide some manual assistance if desired. (And also granted, in some cases maybe maintainers would want to provide manual assistance to AI submissions, but I expect the initial triaging based on whether it's a human or AI would be what makes sense in most cases).
