What problem does it solve?
It helps you validate and harden code changes by getting an independent Codex-based second opinion, then escalating to an adversarial “try to break it” challenge to surface issues a normal review might miss.
Core Features & Use Cases
- Code review with a pass/fail gate: Runs a diff review against your base branch and labels critical findings so you can decide whether to proceed.
- Adversarial challenge mode: Actively looks for edge cases, security holes, race conditions, and failure modes.
- Consult mode with session continuity: Lets you ask Codex questions about the codebase and continue the same thread across turns.
Use Case: You’re about to merge a PR and want confidence that security, reliability, and tricky edge cases weren’t overlooked.
Quick Start
Use the codex skill to review your current branch diff and gate it by running: /codex review.
