How does it measure code complexity?

It uses AST parsing to calculate metrics such as lines of code (LOC), cyclomatic complexity, and nesting depth to provide an objective quality score.

Is it smart enough to ignore test files or generated code?

The skill is context-aware; it applies more lenient standards to test files and can identify or skip auto-generated code to ensure feedback is relevant.

Does it provide specific advice on how to fix the code?

Yes, every detected smell includes a specific refactoring suggestion, an explanation of the negative impact, and an estimated effort level to implement the fix.

What types of code smells can this skill detect?

It identifies a wide range of issues including long methods, deep nesting, magic numbers, God Classes, circular dependencies, and inappropriate intimacy between classes.

Can I use this for architectural reviews?

Yes, the skill specifically looks for architectural smells like leaky abstractions, tight coupling, and missing interfaces.

Security & Testing

Analyzes source code to identify anti-patterns, complexity issues, and technical debt while providing senior-level refactoring advice.

The Code Smell Detector acts as an automated senior developer mentor, scanning your files for quality issues that often evade standard linters. It evaluates code across six major categories including complexity, duplication, and architectural integrity. By calculating metrics like cyclomatic complexity and identifying patterns like 'God Classes' or 'Feature Envy,' this skill provides a comprehensive quality score and actionable suggestions. Whether you are performing a self-review or tackling legacy code, it helps you maintain high standards for readability, testability, and long-term maintainability.
