SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @openai/codex, and includes scripts (resource) components.

What problem does it solve?

The Codex skill helps solve the challenge of reviewing code with a different AI perspective, finding security issues through adversarial challenge, and getting comprehensive information with session continuity for follow-ups.

Core Features & Use Cases

  • Code Review: Get a second independent opinion on code with pass/fail gates.
  • Challenge: Test your code's robustness against adversarial inputs.
  • Consult: Continuously get expert AI consultations for coding-related questions.
  • Use Case: Before pushing code, run a /codex review to catch any overlooked issues, or /codex challenge to uncover edge cases and vulnerabilities.

Quick Start

Use the /codex command followed by 'review', 'challenge', or 'consult' along with relevant code snippets or descriptions of what you are trying to achieve.

FAQPage Schema
How do I use AI to review code for security vulnerabilities?▼

AI code review analyzes your code to find security vulnerabilities and issues using OpenAI Codex. You can run a review command before pushing to catch overlooked issues and get a pass/fail gate assessment.

How can I test my code against adversarial inputs?▼

You test code robustness against adversarial inputs by running a challenge command. This adversarial testing uncovers edge cases and vulnerabilities by having the AI actively challenge your code's logic.

Does OpenAI Codex support session continuity for coding consultations?▼

OpenAI Codex supports session continuity for coding consultations, allowing you to get expert AI advice and continuously ask follow-up questions related to your code without losing context.

What is the best way to get a second opinion on code before pushing?▼

Getting a second opinion on code involves running an independent review before pushing. This approach uses high reasoning power to analyze your code against different coding scenarios and provides pass/fail gates.

Can AI code review integrate with my existing development workflows?▼

AI code review adapts to different coding scenarios and integrates with existing development workflows. You trigger it via command line using specific review, challenge, or consult actions alongside your code snippets.
