FAQPage Schema
How do I get an independent second opinion on my code diff for a formal review?▼

To get an independent second opinion on a code diff, run the Codex CLI against your branch and select review mode to apply a deterministic quality gate on the changes.

What is adversarial testing for code changes and how does it probe robustness?▼

Adversarial testing for code changes probes robustness by challenging the diff to uncover hidden edge cases. Use challenge mode to actively probe your code's weak points.

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

Yes, you need the Codex CLI installed and repository access to run an automated code review, as the tool analyzes the current diff directly within your development workflow.

Can I ask follow-up questions during an automated code analysis session?▼

Yes, you can ask follow-up questions during an automated code analysis by using consult mode, which provides interactive feedback and maintains session continuity for your inquiries.

How do I log gate outcomes and usage telemetry for code reviews?▼

To log gate outcomes and usage telemetry for code reviews, execute the tool against your branch diff; it automatically records evaluation results and usage telemetry during the analysis process.
