AI for Code Review

Coding agents now contribute production code daily at most well-run engineering orgs. Review quality scales with how strict your testing and CI gates are.

What it looks like in practice

Every PR gets an AI reviewer that catches obvious bugs, suggests refactors, generates missing tests, and flags risky changes. Humans make the merge call.

Where AI is strong

  • Style and lint feedback
  • Obvious bug catching
  • Test scaffolding

Where AI still struggles

  • Architectural review
  • Cross-cutting concerns

What to measure

  • PR cycle time
  • Bugs caught pre-merge
  • Test coverage delta
