Summary
An OpenAI developer blog post announcing that Codex Code Review can apply custom repository rules written in AGENTS.md, so that review guidance a few experienced reviewers carry — preserving an API contract, keeping customer data out of logs — is kept next to the code and cited in findings. It motivates the feature with rising pull-request volume making review the bottleneck, reports an internal eval in which rule-guided variants recovered 98% of required custom findings against 58.3% for a baseline, and advises starting with a consequential non-obvious invariant, scoping rules to the code they govern, stating the safe path, and leaving mechanical checks to CI.
