SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you validate and harden code changes by getting an independent Codex-based second opinion, then escalating to an adversarial “try to break it” challenge to surface issues a normal review might miss.

Core Features & Use Cases

  • Code review with a pass/fail gate: Runs a diff review against your base branch and labels critical findings so you can decide whether to proceed.
  • Adversarial challenge mode: Actively looks for edge cases, security holes, race conditions, and failure modes.
  • Consult mode with session continuity: Lets you ask Codex questions about the codebase and continue the same thread across turns.

Use Case: You’re about to merge a PR and want confidence that security, reliability, and tricky edge cases weren’t overlooked.

Quick Start

Use the codex skill to review your current branch diff and gate it by running: /codex review.

Frequently Asked Questions about codex

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I get an automated code review for a pull request diff?

Automated code review for a pull request diff is achieved by running the review mode against your detected base branch. It analyzes changes and provides a clear pass/fail verdict based on critical findings to gate your merge.

What is adversarial testing for code changes and how does it work?

Adversarial testing for code changes actively probes branches to surface edge cases, security holes, race conditions, and failure modes. It works by escalating from a standard review into a challenge mode designed to break the logic.

Can I ask follow-up questions about my codebase after an initial review?

You can ask follow-up questions about your codebase using the consult mode with session continuity. This allows you to continue the same thread across multiple turns for iterative Q&A regarding your code changes.

Does the code review tool support read-only execution for security audits?

The security audit process enforces read-only execution and applies tool gating via safe modes. This ensures your codebase remains untouched while performing security-focused auditing and adversarial challenge checks.

How do I run a security audit on my current branch before merging?

To run a security audit on your current branch, execute the challenge mode against the detected base branch diff. This robustness testing actively looks for security vulnerabilities and tricky edge cases before you proceed.

What are the limitations of using an independent Codex review for diff analysis?

An independent Codex review for diff analysis operates under read-only execution constraints and relies on streaming output via JSON-trace parsing. It gates merges based on critical findings but does not automatically fix or rewrite your code.
