@apilium/refactor-patterns

Detect code smells and suggest refactoring patterns using GoF design patterns and SOLID principles.

Installation

mayros skill install @apilium/refactor-patterns

Usage

Detect Code Smells

Ask Mayros to analyze your code for smells:

Analyze src/services/ for code smells and suggest refactoring patterns.

The skill detects smells from Martin Fowler's catalog:

• Critical: God Class, Duplicate Code
• High: Long Method, Feature Envy, Switch Statements
• Medium: Data Clumps, Primitive Obsession, Long Parameter List, Message Chains
• Low: Lazy Class, Speculative Generality, Parallel Inheritance

Pattern Suggestions

Each smell maps to a specific refactoring technique or GoF pattern:

• God Class --> Extract Class (Single Responsibility)
• Switch Statements --> Strategy Pattern (Open/Closed)
• Feature Envy --> Move Method
• Data Clumps --> Extract Parameter Object
• Long Parameter List --> Builder Pattern

SOLID Analysis

Every suggestion references which SOLID principle is violated and how the recommended pattern addresses it.

Health Score

The skill computes a health score from 0 to 100 based on the number and severity of detected smells. Critical smells deduct 15 points, high smells deduct 10, medium deduct 5, and low deduct 2.

Semantic Predicates

| Predicate | Description | |-----------|-------------| | refactor:smell_detected | Asserted for each smell found | | refactor:pattern_suggested | Asserted for each refactoring recommendation | | refactor:history | Query for previous refactoring analysis |
