SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires codex-cli.

What problem does it solve?

This skill solves the problem of reviewer bias by providing an independent, decorrelated second opinion on code diffs and project plans using a separate model (Codex), ensuring that the implementer's blind spots are caught.

Core Features & Use Cases

  • Adversarial Review: Provides a critical, independent assessment of plans or code without being influenced by the original author's reasoning.
  • Structured Findings: Generates machine-readable JSON reports with severity levels, file locations, and suggested fixes.
  • Use Case: Use this before finalizing a pull request or committing to a complex architectural plan to ensure that edge cases, security risks, and logic errors are identified by a fresh, independent perspective.

Quick Start

Ask the assistant to perform a cross-review on the current plan or diff to get an independent second opinion.

FAQPage Schema
How do I get an independent code review to catch blind spots in my pull request?▼

To get an independent code review, you can use an adversarial cross-review process that analyzes code diffs via a separate, decorrelated model session to identify logic errors and security risks.

What is adversarial testing for architectural plans and when do I need it?▼

Adversarial testing for architectural plans is a decorrelated review process that critically assesses specifications without author bias. You need it before committing to complex project plans to ensure high-integrity verification.

How do I perform a cross-review on a code diff or project plan?▼

To perform a cross-review, prompt the assistant to evaluate your current diff or plan. The skill uses a separate Codex session in a read-only sandbox to generate structured JSON findings with severity levels and suggested fixes.

Do I need Codex CLI to run decorrelated code and plan reviews?▼

Yes, you need authenticated access to the Codex CLI to run decorrelated reviews. The skill uses this separate model environment to ensure objective, non-biased feedback on your software development workflows.

What is the best way to eliminate reviewer bias when finalizing implementation logic?▼

The best way to eliminate reviewer bias is using an independent adversarial review mechanism. It provides a fresh second opinion on implementation logic by utilizing a separate model, catching the original author's blind spots.

What format does the adversarial code review output use for identified security risks?▼

The adversarial code review outputs machine-readable JSON reports. These structured findings include severity levels, file locations, and suggested fixes for identified edge cases and security risks.
