SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides an independent Codex-powered review of code changes to complement human analysis.

Core Features & Use Cases

Review mode: runs codex review against the current branch diff and yields a gate verdict (PASS/FAIL) with token cost.
Challenge mode: performs an adversarial pass to surface edge cases, vulnerabilities, and robustness issues.
Consult mode: analyzes plan files or prompts to offer general coding guidance and questions.

Quick Start

Run /codex review to examine the latest diff, or /codex challenge for adversarial probing, then optionally consult with /codex on plans or prompts.

FAQPage Schema

How do I get an independent AI code review on my branch diff?▼

An AI code review on your branch diff is generated by running review mode against the current changes, which yields a gate verdict of PASS or FAIL along with the token cost.

Can I use adversarial testing to find edge cases and security risks in my code?▼

Adversarial testing to find edge cases and security risks is executed via challenge mode, which performs an adversarial pass to surface vulnerabilities and robustness issues with a rationale.

How do I analyze plan files or prompts for general coding guidance?▼

Analyzing plan files or prompts for general coding guidance is done using consult mode, which evaluates the provided plans to offer general coding guidance and questions.

Does the code review process support structured logging and timeouts?▼

Yes, the code review process supports structured logging and timeouts, logging results in a structured format while enforcing timeouts during the diff analysis against the base branch.

What is the best way to surface performance concerns in code changes?▼

To surface performance concerns in code changes, use an independent Codex-based review that evaluates the diff against the base branch or plan prompts to identify edge cases and performance issues.
