Summary

Temporarily disable all CodeRabbit approvals by setting reviews.auto_approvals.enabled: false. The existing policy does not restrict automatic approval by contributor affiliation. Disabling approvals globally is the conservative stopgap while a contributor-aware policy is evaluated.

Automatic reviews remain enabled. Preserve the existing risk limits and path overrides for a future policy change. This also disables CodeRabbit's automatic request-changes decisions and approval commands; it does not revoke previously submitted approvals.

Validation

• Parsed .coderabbit.yaml with PyYAML and verified that approvals are disabled, automatic reviews remain enabled, and no legacy request_changes_workflow key conflicts with the setting.
• git diff --cached --check.
• Staged-change public-information review: no findings.
• Gitleaks pre-commit hook.

Hosted CodeRabbit behavior has not been exercised with this change.

Severity and risk

Severity: moderate. An external contribution can otherwise receive automated approval without a mandatory human review.

Risk: internal contributions also need another approver, and CodeRabbit will no longer submit request-changes decisions. Existing approvals are not revoked. Revert this change to restore the previous behavior.

AI assistance: Perplexity changed the configuration and drafted this description.

Walkthrough

The configuration changes reviews.auto_approvals.enabled from true to false. The merge-risk policy and other approval settings remain in place.

Merge Risk: Moderate · up to a6cb9

This change stops CodeRabbit from approving new PRs, but approvals it has already given stay valid. Some open PRs could therefore merge without a human review. Dismiss those approvals or block them from counting before merging.

Architecture risk: Low · up to a6cb9

Handle existing CodeRabbit approvals.

The PR notes that it does not revoke existing approvals. On an open PR, a CodeRabbit approval can still satisfy the approval requirement without a human review. The reset workflow dismisses it only after a head synchronization or base-branch edit.

Dismiss existing CodeRabbit approvals, or prevent them from satisfying the requirement while this policy is in effect.
