SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Codex is powerful but raw usage can be brittle; this skill provides an independent, structured second opinion to review changes, challenge assumptions, and guide conversations with Codex.

Core Features & Use Cases

Review mode: perform a code review against the current diff with a gate/verification step.
Challenge mode: run adversarial prompts to stress-test changes and surface edge cases.
Consult mode: ask Codex questions with session continuity for follow-up discussions.
Real-world use case: a developer team wants an extra, objective evaluation before shipping a patch to catch hidden bugs.

Quick Start

Run /codex review on your current branch to get an independent second opinion on the changes.

What is adversarial code review and how does it stress-test planned prompts?▼

Adversarial code review runs challenge prompts to stress-test code changes, surface edge cases, and challenge assumptions before merging. This Skill automates that process using Codex.

Can I ask follow-up questions after getting an initial code analysis?▼

Yes, you can ask follow-up questions after an initial code analysis by using consult mode, which provides session continuity for ongoing discussions with Codex about your project changes and planned prompts.

Does this code review tool work without additional dependencies or components?▼

Yes, this code review tool works without additional dependencies or components, operating as a standalone CLI wrapper around Codex that supports multiple modes with comprehensive failure handling.

What are the limitations of using a CLI wrapper for Codex second opinions?▼

The limitations of using a CLI wrapper for Codex second opinions include potential brittleness from raw Codex usage and the need for comprehensive failure handling, though this Skill provides structured modes to mitigate those risks.
