Code Smell Detector Skill
Automated detection of code smells, anti-patterns, and design issues that indicate deeper problems in the codebase. This skill identifies refactoring opportunities and prioritizes them by impact.
Purpose
Enable systematic detection of code smells for:
- Refactoring prioritization
- Technical debt identification
- Code quality improvement
- Migration preparation
- Design pattern violations
Capabilities
1. Long Method Detection
- Identify methods exceeding line thresholds
- Analyze parameter counts
- Detect high cyclomatic complexity
- Suggest extraction candidates
2. Large Class Identification
- Detect classes with too many responsibilities
- Identify god classes
- Analyze class cohesion
- Suggest decomposition strategies
3. Feature Envy Analysis
- Find methods using other classes' data excessively
- Identify misplaced functionality
- Suggest method relocation
- Map cross-class dependencies
4. Primitive Obsession Detection
- Identify overuse of primitives
- Find missing value objects
- Detect stringly-typed code
- Suggest domain type extraction
5. Parallel Inheritance Hierarchy
- Detect mirrored class hierarchies
- Identify inheritance coupling
- Suggest hierarchy consolidation
- Map inheritance relationships
6. Shotgun Surgery Detection
- Identify changes requiring multiple file edits
- Detect scattered functionality
- Map change propagation patterns
- Suggest consolidation points
7. God Class Identification
- Detect classes doing too much
- Analyze responsibility distribution
- Calculate lack of cohesion metrics
- Suggest single responsibility refactoring
