FAQPage Schema
How do I get an AI second opinion on my code changes before shipping?▼

Adversarial code testing challenges your changes to break or harden them. It analyzes the current diff against the base branch to proactively expose edge cases and potential failures that standard code review might miss.

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

Yes, you need the Codex CLI installed to perform an automated code review. The tool acts as a wrapper around the CLI, using it to analyze diffs and output verbatim results, including reasoning traces and token usage.

What is the difference between review, challenge, and consult modes for AI code analysis?▼

Review mode provides automated pass/fail gating against the base branch, challenge mode performs adversarial analysis to harden changes, and consult mode offers interactive prompts with session continuity for follow-up questions.

Can I select a specific AI model for code review and adversarial testing?▼

Yes, you can select a specific AI model for code review and adversarial testing. The tool supports optional model selection within the Codex CLI to tailor the analysis of your current diff.

How do I check my code diff for security concerns and edge cases?▼

You can check a code diff for security concerns and edge cases by running an automated review against the base branch. The analysis outputs verbatim results, highlighting potential failures and security issues.
