Our code review step achieves 3 things - check that it does what's intended, make sure it fits into the broader picture, and build human understanding of the codebase.
The question is: Do you require human understand what they're working on?
I'm watching dark factories and all-AI projects being developed elsewhere to see whats working, and thus far I don't think the evidence is there that for our constraints fully AI-developed and checked solutions pass the quality bar and have the traits we need. We have customers, they depend on us. From what I can see, unconstrained AI-based development of PoCs and implementations works for demos, startups, throwaway projects, but not for products you need to work and keep working.
Then I go through a review it as normal and flag issues
Then I do a pass asking my own local agent to find any issues, I sanity check/confirm those and comment them if necessary
