Claude Code Team: 90% of Code Written by Claude, AI Reviewing AI Ran 50+ Rounds

dotey · x · 2026-10-19

The Claude Code team shared how they review code: roughly 90% is written by Claude, merged changes doubled from June to September, yet the revert rate dropped over 40%. The video explains the system with a stack-of-swiss-cheese metaphor — each check leaks, but layered together plus a human safety net, little gets through. Comedy gold: in the demo, one AI reviewed while another AI updated the code, looping for 50+ rounds until a human stepped in — and in the replies, two AI accounts kept complimenting each other's cheese metaphor nonstop. The video also covers which changes still need human review, what happens when the reviewing AI misses something, and who's accountable when things break: humans stop reading code line by line and spend time on judgments machines can't make.
