SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Codex gives you an independent, hard-nosed second opinion on code changes, technical decisions, and tricky debugging questions so you can catch mistakes before they ship.

Core Features & Use Cases

Code Review: Review diffs with a pass or fail gate and call out correctness, edge cases, and risky assumptions.
Challenge Mode: Try to break the approach, find weak spots, and pressure-test the plan like an adversarial reviewer.
Consult Mode: Keep a session going across follow-up questions when you need fast, context-aware technical judgment.

Quick Start

Ask the codex skill to review your diff and give you the bluntest useful second opinion.

FAQPage Schema

How do I get an automated second opinion on a git diff before committing?▼

To get a second opinion on a git diff, you provide the code changes to the review session. The system analyzes the diff, applies a pass or fail gate, and flags correctness issues, edge cases, and risky assumptions for you to catch mistakes before shipping.

What is the best way to pressure-test an architecture decision or implementation plan?▼

Pressure-testing an architecture decision is done using an adversarial challenge mode. This mechanism attempts to break your approach, identifies weak spots, and challenges assumptions to ensure your technical plan holds up under scrutiny before implementation.

Can I ask follow-up questions during a code review or debugging session?▼

Yes, you can ask follow-up questions during a review or debugging session. A consult mode maintains session continuity and Git-aware context, delivering fast, context-aware technical judgment across multiple interactive queries.

How does code review handle filesystem boundaries and repository context?▼

Code review enforces strict filesystem boundaries while requiring Git-aware context handling. This ensures the review process stays securely within the permitted repository scope and accurately evaluates the specific code changes provided.

When should I use an adversarial challenge session for debugging?▼

You should use an adversarial challenge session for debugging when you face tricky bugs or complex implementation decisions. It provides an independent, hard-nosed technical consulting perspective to help find weak spots and validate your approach.
