SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Developers frequently need an independent, adversarial second opinion on their code but lack access to a senior engineer at odd hours. This skill wraps the OpenAI Codex CLI to deliver automated code review, security challenge mode, and consultative Q&A directly in your terminal workflow.

Core Features & Use Cases

  • Code Review: Submit a diff for independent review with a pass/fail gate before merging.
  • Challenge Mode: Adversarially test your implementation to find breaking edge cases and security vulnerabilities.
  • Consult Mode: Ask Codex anything with session continuity for follow-up questions, like having a 200 IQ pair programmer on call.

Quick Start

Use the codex skill to review your current branch diff and tell me if it is safe to merge.

FAQPage Schema
How do I get an independent code review for my branch diff before merging?

You can get an independent code review by submitting your branch diff to the Codex CLI wrapper, which analyzes the changes and provides a pass/fail gate to determine if it is safe to merge.

Can I use Codex CLI to find security vulnerabilities and edge cases in my code?

Yes, you can use Codex CLI to find security vulnerabilities and edge cases by enabling the adversarial challenge mode. It tests your implementation to actively find breaking inputs and harden security.

What is adversarial code challenge mode and how does it work for debugging?

Adversarial code challenge mode is a feature that tests your implementation by attempting to break it. It works by analyzing your code to find edge cases and security vulnerabilities, providing an independent second opinion during debugging sessions.

Do I need the Codex CLI binary and Bash to run automated code reviews?

Yes, you need the Codex CLI binary and a Bash execution environment to run automated code reviews. These dependencies are required to execute the wrapper and process the code analysis.

How do I consult Codex for architectural decisions with session continuity?

To consult Codex for architectural decisions with session continuity, use the consult mode to ask questions and receive follow-up answers. It functions like a pair programmer, maintaining context across multiple queries.

What are the limitations of using an AI CLI wrapper for pre-merge code review?

The limitations of using an AI CLI wrapper for pre-merge code review include the need for a Bash execution environment and the Codex CLI binary. It serves as an independent second opinion but does not replace human senior engineer oversight.
