Claude Code Review Is GA and Never Fails a PR. Anthropic's Own Repos Block on Findings

On October 15, Anthropic made its Claude Code review tool generally available to Claude Team and Enterprise organizations. The review system is designed to never fail a pull request check. When a review finding remains open, Anthropic's own repositories block the merge of the pull request. The review process involves a few agents reading the code diff and surrounding context, with a verification pass discarding any false positives.

The tool marks findings as Important, Nit, or Pre-existing, and posts them as inline comments on the pull request along with a dedicated check run named Claude Code Review. The review runs on Anthropic's infrastructure with read-only access to the code and only works with GitHub repositories. It is not available for organizations with Zero Data Retention, HIPAA configurations, or customer-managed encryption keys.

The team posts that a review never approves or blocks a pull request, and the check run always concludes as not a failure. The team also explains that approving a pull request is still a human decision, and the product posts findings, not approvals. If you want findings to block a merge, two options are available: requiring resolved conversations or gating on Important findings only. A pre-merge step script is provided to enforce these rules in your repository.
