Which programming languages are supported?

The auditor uses universal Grep and Glob patterns but includes language-specific detection logic for major stacks like Node.js, Python, Java, and C#.

How are the audit results delivered?

The skill generates a comprehensive Markdown report including a category compliance score, severity-tagged findings, and estimated effort for suggested refactors.

What specific code principles does this skill audit?

It audits 10 types of DRY (Don't Repeat Yourself) violations, KISS (Keep It Simple, Stupid), YAGNI (You Aren't Gonna Need It), error handling, and dependency injection patterns.

Can I audit specific modules instead of the whole project?

Yes, the skill is domain-aware and can be configured to scan specific paths or modules independently using the domain-aware scanning mode.

Does the Auditor automatically apply fixes to my code?

No, the skill follows a strict 'report only' policy. It identifies issues and provides detailed recommendations, leaving the implementation to the developer.

Security & Testing

Audits codebases for architectural integrity by detecting DRY, KISS, and YAGNI violations while evaluating error handling and dependency injection patterns.

The Code Principles Auditor is a specialized L3 worker skill designed to act as an automated architectural gatekeeper for your repository. It performs deep analysis across ten distinct types of DRY (Don't Repeat Yourself) violations, identifies over-engineering via KISS and YAGNI checks, and audits critical infrastructure like centralized error handling and dependency injection. By generating structured reports complete with compliance scores, severity levels, and specific refactoring recommendations based on a built-in decision tree, it enables teams to proactively manage technical debt and maintain high-quality, modular codebases.
