SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provide an independent, brutally honest assessment of code changes by wrapping the Codex CLI for review, challenge, and consult workflows. It helps teams validate diffs, surface edge cases, and explore alternative approaches without bias or sugar-coating.

Core Features & Use Cases

  • Code review mode: perform a standards-based review of diffs with gate-style pass/fail decisions.
  • Adversarial challenge mode: probe changes for edge cases, robustness gaps, and failure modes.
  • Consult mode: ask Codex questions with session continuity to clarify design decisions or get a second opinion.

Quick Start

Run /codex review to obtain an independent assessment of your current diff.

FAQPage Schema
How do I get an independent code review for my current diff?

To get an independent code review for your diff, you can use an automated CLI tool to perform a standards-based assessment and output a gate-style pass or fail verdict.

What is adversarial code testing and when do I need it?

Adversarial code testing probes changes for edge cases, robustness gaps, and failure modes. You need it to surface vulnerabilities and validate diffs without bias before merging.

Do I need the Codex CLI installed to run an automated code review?

Yes, you need the Codex CLI installed to run automated code review workflows, as the tool wraps the CLI to provide gate verdicts and session management.

Can I ask Codex questions with session continuity during a code consultation?

Yes, you can use consult mode to ask Codex questions with session continuity, allowing you to clarify design decisions and track discussions over multiple interactions.

What's the best way to probe code changes for failure modes without bias?

The best way to probe for failure modes without bias is using adversarial challenge mode, which independently probes changes for robustness gaps and edge cases.

Are there limitations to using automated gate-style verdicts for code review?

Automated gate-style verdicts are limited to providing a second opinion based on the diff provided and do not replace comprehensive human review or sugar-coat assessments.
