Summary

You don't need to manually review every AI-generated PR—Intercom proved AI-approved code is 5x faster to review and has lower revert rates than human-reviewed code. By implementing risk scoring and auto-approval systems, engineering teams can safely eliminate low-risk PRs from their queue while maintaining compliance frameworks like SOC 2.

Key Takeaways

  1. Intercom 2-3x'd their PR throughput by implementing AI approval systems, with AI-approved PRs shipping 5x faster than human-reviewed ones while maintaining higher quality and lower revert rates.
  2. Risk scoring bots can categorize PRs by safety level (blast radius, correctness, test coverage) to identify which ones can be auto-approved without human review, freeing engineers for complex work.
  3. AI-generated code doesn't weaken compliance—SOC 2, HIPAA, and other frameworks allow auto-approval if it's auditable, queryable, defensible, and documented in your code review policies.
  4. Use AI agents (like Vercel's Eve) to build PR review automation quickly—Claire built a functional code review risk-scoring bot in 30 minutes using modern AI frameworks.
  5. Devon (AI-authored) PRs often represent high-volume, low-risk code—ideal candidates for automation. Categorizing PRs by source and risk level reveals which ones can skip human review entirely.

Everybody is drowning in AI created PRs. When anyone can code, anyone can cook and anyone can vibe anything to GitHub. That means that a lot of us are sitting on a big queue of pull requests that then we have to review. If you are an engineering leader or a software engineer in a company that has embraced AI in any way, shape, or form, you feel this pain. And I get this question all the time. We've figured out how to code with AI. Now, what do we do with all these PRs? Well, people smarter than us have figured this out. And you know what the answer is? You don't have to review all your PRs. Yep, you heard it here first. You do not actually have to review one-on-one by a human all those PRs. So, in today's episode, I'm going to show you how to build your own PR review, risk scoring, and aut…
