What problem does it solve? Getting a trustworthy second opinion on code changes is hard: self-review misses blind spots, and switching tools breaks flow. This Skill wraps the OpenAI Codex CLI so you can request an independent diff review, an adversarial challenge of your implementation, or a free-form consultation without leaving your current session. ## Core Features & Use Cases - Independent Code Review: Runs codex review as a pass/fail gate on your diff, catching issues your own review missed. - Adversarial Challenge Mode: Tries to break your code by attacking assumptions, edge cases, and failure paths. - Consult with Session Continuity: Ask Codex anything and keep follow-up questions in the same session context. - Use Case: Before merging a risky refactor, invoke the review mode to get a pass/fail verdict, then run challenge mode to probe the weakest part of the change. ## Quick Start Ask the assistant to run a codex review of the current diff and report whether it passes or fails.
