How Anthropic Merges 30,000 Code Changes a Day with Claude First-Pass Review
AI Engineer · youtube · 2026-10-29
An AI Engineer interview with Manish Kapur (Sonar) and Addy Osmani (Anthropic) on scaling code review in the coding-agent era.
Key points:
- Anthropic's daily merged changes grew from 2,500 to 30,000, with agents opening PRs faster than humans can review
- Claude does first-pass review, backed by real verification evidence
- They contrast "light" vs. "dark" software factories and argue every loop needs independent, multi-layered verification
- Sonar's State of Code survey data: throughput is up but merges are failing — "coding is solved, confidence isn't"
- Discussion of controls, permissions, sandboxes, and labeling agent-written PRs to decide when merging is safe
