This is where the human element is critical, but cause it'll infinite loop review feedback if you let it and the code will easily go off the rails into an over engineered mess. That's why I review the code before/after as well as review the actual feedback itself - and often give the feedback to different AI to get its opinion as the other AI doesn't have a vested interest in it and can be more critical. At some point though you do have to cut them off and ship.
