GitHub says 1-in-5 PRs now involve an agent. LinearB found agentic PRs take 5.3x longer to even get picked up. We tripled throughput without redesigning the process - then blamed the AI when 81% of orgs reported more production incidents (CloudBees, 2024).
Dev trust in AI code dropped from 40% to 29% in a year (Stack Overflow). That's not a quality gap. It's a "reviewing the wrong artifact" problem.
The shift I've seen work: less investment in line-by-line diff review, more in contracts that make bad agent output fail loudly before anyone reads it - strong types, property tests, invariant assertions that say "a correct implementation here cannot return null" and catch it in CI, not a PR comment at 4pm.
"Verify, don't review" isn't a shortcut. It's the only model that scales when PR count triples and reviewer time doesn't.
Where's your team's bet - better prompts and more reviewers, or tighter contracts?
