SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides an independent, adversarial second opinion on code changes and a consultative channel for coding questions so teams catch issues a single reviewer might miss.

Core Features & Use Cases

  • Three modes: review (diff-based code review with pass/fail gate), challenge (adversarial testing to try to break changes), and consult (interactive Q&A with session continuity).
  • Safety and integration: enforces a filesystem boundary, integrates with the Codex CLI, logs review results to gstack analytics, and supports model reasoning overrides like --xhigh.
  • Use Case: Run a codex review on a feature branch to surface P1/P2 findings, compare results with an earlier Claude review, and log outcomes to the plan file for downstream triage.

Quick Start

Run /codex review to run an independent Codex code review of your current branch diff.

FAQPage Schema
How do I run an automated code review on a git diff?▼

An AI second-opinion code review provides an independent, adversarial analysis of your code changes to catch issues a single reviewer might miss. It evaluates git diffs and plan files to surface P1/P2 findings for downstream triage.

How does adversarial testing work for code changes?▼

Adversarial testing challenges your code changes to try to break them using AI-driven probes. It operates within an enforced filesystem boundary to safely identify vulnerabilities and edge cases in your git diff.

Can I use an interactive Q&A session for coding questions with session continuity?▼

Yes, consult mode provides an interactive Q&A session with session continuity for coding questions. It acts as a consultative channel to address coding inquiries while maintaining conversational context.

Does the Codex CLI support model reasoning effort overrides?▼

Yes, the Codex CLI integration supports model reasoning effort overrides like the --xhigh flag. This allows you to adjust the analytical depth applied during code review and adversarial testing.

What are the limitations of using an AI second-opinion code review?▼

A key limitation is the enforced filesystem boundary, restricting analysis to local diffs and plan files only. Additionally, review gating and telemetry must be logged to gstack analytics for downstream triage.
