You can get an independent second opinion on code changes by routing diffs through Codex CLI to surface gaps, issues, and improvements before shipping. The Skill evaluates your latest changes and returns a structured result with a gate verdict and telemetry.

Adversarial code review works by invoking challenge mode in Codex CLI to stress test your diffs and uncover hidden edge cases. It applies adversarial testing logic against your code changes to expose vulnerabilities before deployment.

Yes, you must have the Codex CLI installed and available in your environment before using this Skill. It reads diffs or plan context and invokes the CLI directly to perform code reviews, adversarial testing, and prompt validation.

Yes, you can use consult mode to validate prompts and instructions against quality and safety standards. The Skill routes your ad-hoc inquiries through Codex CLI to provide an honest assessment of your prompt logic and instructions.

The best way to review code diffs for edge cases is to run the review or challenge modes to obtain a brutally honest second opinion. This approach surfaces gaps, issues, and potential improvements by independently evaluating your changes before they are merged.

The Skill is limited to reading diffs and plan context, meaning it requires the Codex CLI to be fully installed and functional. It cannot review code without accessible diffs or plan context, and it depends entirely on the CLI for its evaluation logic.
