SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Claude Code lacks a truly independent second opinion on code quality. This skill wraps the OpenAI Codex CLI to provide an independent, brutally honest review, an adversarial challenge mode to stress-test your code, and a consult mode for follow-up questions with session continuity.

Core Features & Use Cases

  • Code Review: Get an independent diff review with a pass/fail gate. Codex analyzes your changes against the base branch and flags critical findings like security issues or logic bugs.
  • Adversarial Challenge: Ask Codex to try to break your code. It acts as a "200 IQ autistic developer" stress-testing your implementation to find edge cases and weaknesses before users do.
  • Consult Mode: Ask Codex anything with session continuity for follow-up queries, getting a second opinion on architecture decisions, design tradeoffs, or specific technical problems.

Quick Start

Use the codex skill to review your current branch diff and report any critical findings with a pass or fail verdict.

FAQPage Schema
How do I get an independent AI code review on my git diff?

To get an independent AI code review on your git diff, this Skill wraps the OpenAI Codex CLI to analyze your current branch changes against the base branch, providing a pass/fail quality gate verdict on critical findings.

Can I use AI to stress-test my code for edge cases before deployment?

You can use AI to stress-test your code for edge cases by running the adversarial challenge mode, which acts as a highly critical developer to find weaknesses and logic bugs in your implementation before users do.

Does this code review tool require OpenAI Codex installed?

Yes, this code review tool requires the OpenAI Codex CLI binary to be installed globally via npm on your system before you can execute reviews, challenges, or consult modes within your git-based projects.

What is an adversarial challenge mode for software development?

Adversarial challenge mode is an independent testing process where an AI attempts to break your code implementation by stress-testing it to discover edge cases, security issues, and architectural weaknesses before deployment.

How do I maintain session continuity for follow-up architecture questions?

To maintain session continuity for follow-up architecture questions, the consult mode allows you to ask an independent AI anything about design tradeoffs or debugging problems while preserving the context of previous queries.

What are the limitations of using a second AI opinion for code quality?

A limitation of using a second AI opinion for code quality is that it is scoped exclusively to git diff outputs against a detected base branch, meaning it cannot review uncommitted files or non-git project architectures.
