Provides an independent, brutally honest second-opinion on code changes by wrapping the Codex CLI to review diffs, challenge them adversarially, or answer questions with session continuity.

Core Features & Use Cases

Three modes: Review for diff-based pass/fail governance, Challenge to probe for weaknesses, and Consult to ask Codex about code with session memory.
Lightweight integration for code reviews, security reviews, and on-demand architectural questioning.

Quick Start

Run /codex review or /codex challenge on your current diff to start; then pick the mode that fits.

FAQPage Schema

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

You can get an independent AI code review by running the /codex review command on your current diff. This triggers a pass/fail governance check using the Codex CLI to evaluate your code changes.

What is adversarial code review and how does it challenge code changes?▼

Adversarial code review probes your code changes for weaknesses by challenging assumptions. Running the /codex challenge command applies this technique to actively identify potential flaws in your diff.

Can I ask an AI questions about my codebase with session continuity?▼

Yes, you can ask an AI questions about your codebase with session continuity by using the /codex consult command. This mode leverages the Codex CLI to answer architectural questions while retaining session memory.

Do I need the Codex CLI installed to use this code review wrapper?▼

Yes, you need the Codex CLI installed because this Skill functions as a lightweight wrapper around it. The CLI provides the underlying processing logic for reviewing diffs, challenging code, and consulting.

What is the best way to use AI for security reviews and architectural questioning?▼

The best way to use AI for security reviews and architectural questioning is to apply the review and consult modes. These modes provide diff-based governance and on-demand questioning with session memory across your codebase.

What are the limitations of using a CLI wrapper for code reviews?▼

The limitation of using a CLI wrapper for code reviews is that it relies entirely on the Codex CLI for processing. It functions as a lightweight integration for diff-based governance rather than a standalone code analysis engine.
