How the Claude Code team does code review

What happened

The Claude Code team has shifted from a traditional gate‑based code review to a continuous, machine‑driven process that reduces human review time while keeping error rates low. Most changes are first examined by automated agents that run tests, builds, or visual checks, and only a single human reviewer—often the author—intervenes if needed. This approach has doubled the number of merged pull requests between June and September while cutting reverts by over 40%. The team tracks human approvals, comments, and wait times to ensure that automation truly saves effort without increasing incidents.
