I would if the PR was clearly written by AI. I'm fine with the PR author using AI, but only to draft the PR. They should be editing the shit out of it for the final version before submitting it.
- Human -> AI: OK
- AI -> AI: OK
- AI -> Human: Not OK (at least here)
AI code reviews are the same as AI pull requests. Do you want that firehose? The suggestions might be good. But do you want to add a deluge of work items to that part of the workflow? Do you want the PR owner to be the one to triage feedback before it gets to them? After they have already done it themselves, perhaps with an even better model?
