SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides an independent, brutal second opinion on code changes by wrapping the OpenAI Codex CLI, helping teams spot issues, gaps, and opportunities before shipping.

Core Features & Use Cases

  • Review mode for diffs with a pass/fail gate to quickly validate changes.
  • Challenge mode to adversarially test implementations and uncover edge cases.
  • Consult mode to ask Codex questions with session continuity for follow-ups.
  • Safe-guards via a boundary prompt to prevent leaking repository data.

Quick Start

Run codex on the current diff to get an independent review.

FAQPage Schema
How do I get an independent AI code review on a diff?▼

You can get an independent AI code review on a diff by wrapping the Codex CLI to analyze changes and provide a pass/fail gate. This approach evaluates diffs and prompts to reduce shipping risk.

Can I use Codex CLI to adversarially test my code changes?▼

Yes, you can use a wrapper around the Codex CLI to adversarially test code changes. The challenge mode probes implementations to uncover edge cases and test the boundaries of your code before deployment.

Does an AI second opinion on pull requests leak my repository data?▼

When using a Codex CLI wrapper for an AI second opinion on pull requests, repository data is protected. It enforces a filesystem boundary prompt to prevent leaking sensitive repository data during diff analysis.

What are the prerequisites for automating code review with the Codex CLI?▼

The prerequisite for automating code review with the Codex CLI is having the Codex binary installed on your system. Once installed, you can run the tool against your current diff to validate changes.

How do I ask follow-up coding questions after an initial diff analysis?▼

To ask follow-up coding questions after an initial diff analysis, you can use consult mode. This mode queries the Codex CLI with session continuity, allowing for iterative follow-ups on previous results.
