SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

OpenAI Codex CLI wrapper — three modes. Code review: independent diff review via codex review with pass/fail gate. Challenge: adversarial mode that tries to break your code. Consult: ask codex anything with session continuity for follow-ups. The "200 IQ autistic developer" second opinion. Use when asked to "codex review", "codex challenge", "ask codex", "second opinion", or "consult codex". (gstack)

Core Features & Use Cases

  • The Codex CLI wrapper provides three modes: code review, adversarial challenge, and consult.
  • Supports session continuity and automated critiques to accelerate debugging and learning.
  • Use cases include evaluating diffs, stress-testing code, and asking Codex questions during development.

Quick Start

Run /codex review to start a code review, or /codex challenge to test robustness.

FAQPage Schema
How do I get an independent second opinion on my code diff?

To get an independent second opinion on a code diff, you can use an adversarial review wrapper that reads repository context and provides a pass/fail gate critique. It evaluates changes independently to catch issues missed during standard reviews.

How does adversarial code testing work for stress-testing application logic?

Adversarial code testing works by actively attempting to break application logic and expose edge cases. It analyzes repository context to generate targeted critiques and stress-test scenarios, challenging assumptions made during initial development.

Do I need Codex CLI installed to run an AI-assisted code review?

Yes, you need Codex CLI installed and accessible to run this AI-assisted code review. The wrapper operates by passing context and commands to the local CLI environment, requiring it to be present for review, challenge, and consult modes.

Can I maintain session continuity when I ask an AI assistant follow-up questions about my code?

Yes, you can maintain session continuity when asking an AI assistant follow-up questions about your code. Consult modes support ongoing sessions, allowing developers to ask sequential questions while retaining previous context for debugging and learning.

What is the best way to challenge code robustness before merging a pull request?

The best way to challenge code robustness before merging is running an adversarial challenge mode that attempts to break your code. It reads the current repository context to guide targeted critiques, stress-testing logic against edge cases.

When should I use an adversarial AI review instead of standard code review tools?

Use an adversarial AI review when you need an independent, brutally honest critique that standard code review tools do not provide. It is designed to aggressively challenge assumptions and stress-test robustness rather than just checking syntax or formatting.
