How common something is before you test for it. When the thing is rare, even a good detector's alarms are mostly wrong, because the many good cases set off more false alarms than the few bad ones set off true ones.
Your gates and your reviewer agents are detectors. If one change in thirteen is broken, most refusals land on good work, and an agent told to satisfy them rewrites good code. The same sum applies to you in an interview: when nearly everyone uses AI, saying you do tells them almost nothing.
“Before we make this reviewer a blocking check, measure it. Run it over our last 50 merged pull requests, count how many it would have stopped, and mark each stop as a real problem or not, with the evidence. Tell me how many of its refusals were right.”
