What problem does it solve?

Reduces the risk of shipping questionable code by providing independent, mode-based feedback from the Codex CLI on your diffs and questions.

Core Features & Use Cases

Review mode: Independent diff review with a pass/fail gate to catch issues early.
Challenge mode: Adversarial testing that tries to break your changes and surface edge cases.
Consult mode: Ask Codex questions with session continuity for follow-ups.
Handy for teams that want a second opinion without relying on a single AI.

Quick Start

Install the Codex CLI and run codex against your repository to get a second opinion on your code changes.

FAQPage Schema

How do I get a second opinion on my git diff before shipping code?▼

You can get a second opinion on your git diff by using an automated code review tool that parses your repository changes and provides independent feedback on implementation quality and potential security concerns with a pass or fail gate.

What is adversarial testing for code changes and how does it find edge cases?▼

Adversarial testing for code changes works by actively trying to break your modifications to surface hidden edge cases. This challenge mode mechanism pushes your diff against unexpected scenarios to identify potential failure points early.

Do I need Codex CLI installed to run automated code reviews?▼

Yes, you need Codex CLI installed and accessible in your PATH environment to run automated code reviews. The review process relies on the CLI to parse your repository changes and generate independent feedback.

Can I ask follow-up questions about my code changes after an initial review?▼

Yes, you can ask follow-up questions about your code changes using consult mode, which provides session continuity. This allows you to maintain context across multiple questions for deeper analysis of your implementation.

What is the best way to review implementation quality without relying on a single AI?▼

The best way to review implementation quality without relying on a single AI is to use an independent mode-based feedback system. This approach provides multiple perspectives on your diffs by leveraging separate challenge and review mechanisms.

Does the code review tool read git state to determine the base branch?▼

Yes, the code review tool reads git state to determine the base branch for your changes. This allows it to accurately parse the correct repository diff and provide feedback specific to your current modifications.
