SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the need for an independent, blunt assessment of code changes by wrapping the Codex CLI to provide code reviews, adversarial challenges, and consult-style prompts in a cohesive workflow.

Core Features & Use Cases

Wrapper around the Codex CLI enabling three modes: review for independent gatekeeping, challenge to stress-test changes, and consult for ask-anything questions with session continuity.
Supports reproducible governance with session IDs, telemetry, and analytics about usage and outcomes.
Useful for codebases needing external opinions on diffs, safety checks, and design gaps during development and review.

Quick Start

Install Codex CLI and then use the /codex commands to review, challenge, or consult the current branch changes.

FAQPage Schema

How do I get an independent code review for my current branch diff?▼

You can get an independent code review by wrapping the Codex CLI to stress-test branch diffs and provide blunt assessments. It acts as a gatekeeper across review, challenge, and consult modes.

What is an adversarial code challenge and how does it work?▼

An adversarial code challenge stress-tests your code changes to expose design gaps and safety issues. It works by applying blunt prompts against your diffs to ensure reproducible governance.

Do I need to install the Codex CLI before using this code review wrapper?▼

Yes, you must install the Codex CLI before using this wrapper. Once installed, you can execute Bash-based commands to initiate session management, telemetry, and plan-mode integration for codebase governance.

Can I track usage analytics and session IDs for code consultations?▼

Yes, you can track usage analytics and session IDs for code consultations. The wrapper implements reproducible governance by maintaining session continuity and recording telemetry across interactive prompts.

When should I use an independent gatekeeper for code changes?▼

You should use an independent gatekeeper for code changes when your codebase needs external opinions on diffs, safety checks, and design gap identification during development and review.

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

Limitations include relying entirely on the underlying CLI's capabilities and requiring Bash-based execution. It functions strictly as a wrapper for interactive prompts and does not modify code directly.
