This release is a quick cleanup update for developers who use Codex's automatic code review tool, known as "Guardian." A recent update to the AI's instructions accidentally broke how the Guardian tool behaves and formats its requests. This release undoes those changes to make sure the tool goes back to working smoothly and reliably.
Fixes
- Restored Guardian Auto-Review Behavior: In a previous update, the team changed the "prompts" (the instructions given to the AI) for the Guardian auto-review system. Unfortunately, this caused a "regression"—which is developer speak for accidentally breaking features that used to work perfectly. It messed up the tool's behavior and the way it formatted its requests. This update rolls back those changes, restoring the original, working Guardian policy and tool behavior.
Breaking changes
No breaking changes in this release.
