What problem does it solve? Getting a second opinion on code changes usually means switching tools or pasting diffs into another chat. This Skill brings the OpenAI Codex CLI into your current session so you can request an independent review, an adversarial challenge, or a general consultation without leaving your workflow. ## Core Features & Use Cases - Independent Code Review: Runs codex review on your diff with a pass/fail gate, giving an outside perspective before you ship. - Adversarial Challenge Mode: Tries to break your code by attacking assumptions, edge cases, and design decisions. - Consult with Session Continuity: Ask Codex anything and keep follow-up context across questions. - Use Case: Before merging a risky refactor, invoke the skill to have Codex review the diff, then run challenge mode to probe for failure modes you missed. ## Quick Start Ask the agent to run a codex review on the current branch diff and report any blocking issues.
