name	code-quality-rules
description	Code quality rules covering anti-duplication, decomposition, and extraction patterns. Use when refactoring code, reviewing for code smells, reducing duplication, extracting functions, or improving code structure. Covers DRY principles, SOLID, single responsibility, and refactoring patterns.

Code Quality Rules

When to Use

• Refactoring existing code for better structure
• Reviewing code for duplication and code smells
• Extracting functions, constants, or shared utilities
• Decomposing large files, classes, or functions
• Applying SOLID principles and design patterns
• Code review sessions focused on maintainability

Rules

This skill bundles three rule sets. Load the specific reference when needed:

• Anti-Duplication Rules — DRY principles, deduplication, code reuse patterns
• Decomposition Rules — Single responsibility, function size, module boundaries
• Extraction Rules — Constants, magic numbers, shared logic extraction
