FAQPage Schema
How do I get a second opinion on my code changes before merging?▼

You can get a second opinion on code changes by submitting a diff or commit hash for an independent review that applies a pass/fail gate to verify code integrity and provide developer insights.

What is adversarial testing for code development workflows?▼

Adversarial testing is a challenge mode that attempts to break your code to test its robustness. It actively probes for vulnerabilities to enhance security and ensure code reliability before deployment.

How do I start a code review using a commit hash?▼

To start a code review, input the designated trigger command followed by the commit hash or code snippet you wish to review. The system will then analyze the diff and provide feedback.

Does this code review tool require specific command line dependencies?▼

Yes, performing this code review and consultation requires Bash, Read, Write, Glob, Grep, and AskUserQuestion dependencies to analyze diffs, search files, and manage session continuity.

Can I ask follow-up questions after the initial code consultation?▼

Yes, you can ask follow-up questions after the initial code consultation. The consultation feature supports session continuity, allowing for iterative queries and deeper project insights.

What is the best way to verify code robustness and security during development?▼

The best way to verify code robustness is to use an adversarial challenge mode that actively tries to break your code. This testing exposes vulnerabilities and provides an expert second opinion.
