I watched Claude Code review a pull request in 30 seconds that would take me 2 hours. It found bugs I missed. It suggested improvements I hadn't thought of. It even caught a potential security vulnerability.

And I felt something I haven't felt since I started coding: fear.

What Happened

Last week, our team decided to test Claude Code on our codebase. We gave it a real PR — 847 lines of changes across 12 files. The kind of PR that makes you want to close your laptop and go for a walk.

My review: 2 hours. Found 3 issues. Approved with comments.
