What problem does it solve?

The Codex CLI wrapper provides a brutal, independent second opinion on code changes by interfacing with the OpenAI Codex CLI to review, challenge, or answer questions.

Core Features & Use Cases

Independent review: perform a diff review with a pass/fail gate.
Adversarial testing: run a challenge mode that tries to break your code.
Interactive consultation: ask Codex for a quick, session-continuous answer to questions about your code.
Use cases: use after a PR to validate changes, or to sanity-check complex parts of a feature.

Quick Start

Run /codex review on your latest diff to get a second opinion.

What is the best way to validate code changes after a pull request?▼

The best way to validate code changes after a pull request is to run a review on your latest diff. This provides a brutal second opinion and a pass/fail gate to ensure code safety.

When should I use challenge mode versus review mode for code validation?▼

Use review mode for safe diff validation with a pass/fail gate, and use challenge mode when you need adversarial testing to actively try breaking your code. Consult mode fits interactive questions.
