SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides an independent, brutally honest second opinion on code changes by wrapping the Codex CLI to review diffs, assess risks, and challenge assumptions before you merge.

Core Features & Use Cases

Independent diff analysis: runs Codex on your branch diffs to surface edge cases, potential bugs, and design gaps.
Flexible modes: review, challenge, and consult to match typical code-review workflows and knowledge gaps.
Clear outputs: surfaces gate decisions and an cost/tokens estimate to inform decision-making.

Quick Start

Invoke the /codex skill to get a brutally honest second opinion on your code diff.

FAQPage Schema

How do I get an independent AI code review on my branch diffs before merging?▼

To get an independent AI code review on branch diffs, you can use a CLI assistant that wraps the Codex CLI to analyze changes, surface potential bugs, and challenge your design rationale. It provides gating decisions and cost estimates to inform your merge.

What is adversarial testing for code changes and how does it challenge assumptions?▼

Adversarial testing for code changes challenges your assumptions by applying an independent AI to actively find edge cases, design gaps, and potential bugs in your diffs. This second-opinion analysis exposes risks before you merge a feature branch.

Do I need the Codex CLI installed to run an AI assistant for pull request reviews?▼

Yes, you need the Codex CLI installed to run this AI assistant for pull request reviews. The tool acts as a wrapper around the CLI, requiring it to process your diffs, manage tokens, and output gating decisions for your code changes.

Can I use AI to estimate token costs and gate merges for active feature branches?▼

Yes, you can use AI to estimate token costs and gate merges for active feature branches. The tool surfaces gating decisions and cost estimates based on standard outputs, helping you assess risks and manage expenses before merging diffs.

What are the limitations of using a CLI wrapper for independent code analysis?▼

Limitations of using a CLI wrapper for independent code analysis include its dependency on the external Codex CLI being pre-installed. It is strictly a second-opinion tool for reviewing diffs and plan changes, not an automated merge executor.
