# Code Complexity Analyzer Skill

## Overview

Analyzes code complexity metrics including cyclomatic complexity, cognitive complexity, code smells, duplicate code detection, and technical debt scoring.

## Capabilities

- Calculate cyclomatic complexity
- Calculate cognitive complexity
- Identify code smells
- Dependency analysis
- Duplicate code detection
- Technical debt scoring
- Maintainability index calculation
- Lines of code metrics

## Target Processes

- refactoring-plan
- performance-optimization
- system-design-review

## Usage Example

```javascript
{
  kind: 'skill',
  skill: {
    name: 'code-complexity-analyzer',
    context: {
      paths: ['src/**/*.ts'],
      metrics: ['cyclomatic', 'cognitive', 'loc', 'dependencies'],
      thresholds: { cyclomatic: 10, cognitive: 15 }
    }
  }
}
