## Summary

Anthropic’s Claude Code team has slashed the time engineers spend on code reviews by over 40% since June, while nearly doubling pull request merges. The shift relies on AI agents handling most routine checks before human review, reducing reverts and incidents. Claude agents now review code continuously—like spellcheck—before pull requests are opened, catching errors early and freeing humans for higher-level scrutiny. The team tracks metrics like approvals per PR, comment volume, and revert rates to ensure AI doesn’t just move human effort elsewhere.

Key to the process is verification: Claude agents run tests, lint checks, and end-to-end validations before human review. Mistakes are fixed iteratively, with agents flagging issues and humans approving fixes. Security and risk tiers are automated, but sensitive changes still require human sign-off. The team also uses AI to generate explainers and visualizations for codebases, shifting learning from line-by-line diffs to targeted understanding. Open collaboration in Slack channels and shared ownership further reduce bottlenecks, ensuring quality without slowing down development.

## Key points

- Anthropic’s Claude Code team cut human review time by 40% while doubling PR merges since June
- AI agents now review code continuously before PRs, reducing reverts and freeing humans for complex checks
- Security and risk tiers are automated, but sensitive changes still require human approval

## Why it matters

This approach could redefine how AI-driven teams scale code review without sacrificing quality, offering a blueprint for other engineering teams handling high-volume agent-generated code.
