SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Leverages the Codex CLI to provide an independent, brutally honest second opinion on code changes, surfacing issues before merging.

Core Features & Use Cases

  • Review mode: evaluate diffs against the base branch with a pass/fail gate.
  • Challenge mode: adversarial testing to break changes and reveal edge cases.
  • Consult mode: interactive prompts to gather quick, actionable feedback on prompts or plans.
  • Use Case: a developer submits a PR and wants a second AI perspective on potential failure modes or policy breaches.

Quick Start

Run Codex to inspect the current branch diff or plan; choose a mode to start the analysis.

FAQPage Schema
How do I get an independent AI code review on my pull request diff?▼

To get an independent AI code review, you can use the review mode to evaluate your branch diff against the base branch, which generates a pass/fail gate to surface issues before merging.

Can I use CLI tools for adversarial code review to find edge cases?▼

Yes, you can use the challenge mode for adversarial testing to break changes and reveal edge cases, providing a brutally honest second opinion on your code.

Do I need the codex binary installed to run code review sessions?▼

Yes, you need the codex binary available on your PATH to run the assessment, which respects model selection and reports gate outcomes, token usage, and session traces.

What is the best way to gather quick AI feedback on a development plan?▼

The best way to gather quick feedback is using the consult mode, which provides interactive prompts to gather actionable feedback on prompts or plan files.

What limitations should I expect with AI-assisted diff analysis?▼

AI-assisted diff analysis operates strictly on diffs against the base branch, plan files, and ongoing sessions, meaning it requires the codex binary and does not evaluate code outside the provided changes.

Does this adversarial code assessment support tracking token usage and session traces?▼

Yes, the adversarial code assessment supports tracking by reporting gate outcomes, token usage, and session traces across all modes for integration into your workflow.
