description: Provides methodologies, metrics, and best practices for analyzing code structure, complexity, and quality
version: 1.0.0

Overview

This skill provides comprehensive knowledge for code analysis including complexity metrics, anti-pattern detection, refactoring strategies, and code quality assessment across multiple programming languages.

Complexity Metrics

Cyclomatic Complexity

  • •Low: 1-10 (simple, easy to test)
  • •Medium: 11-20 (moderate complexity, acceptable)
  • •High: 21-50 (complex, needs refactoring)
  • •Very High: 51+ (critical, must refactor)

Cognitive Complexity

Measures how difficult code is to understand based on nesting, control flow breaks, and recursion.

Code Smells to Detect

  • •Long Methods: >50 lines
  • •Large Classes: >300 lines
  • •Duplicate Code: Repeated blocks
  • •Long Parameter Lists: >5 parameters
  • •Deep Nesting: >4 levels
  • •God Objects: Classes doing too much
  • •Dead Code: Unused functions/variables

Refactoring Strategies

  • •Extract Method: Break long methods into smaller ones
  • •Extract Class: Split large classes by responsibility
  • •Replace Conditional with Polymorphism
  • •Simplify Conditional Expressions
  • •Remove Duplicate Code

When to Apply

Use when analyzing codebase structure, identifying refactoring opportunities, or assessing code quality.
