How does this skill help prevent over-engineering?

It follows a 'Simplicity First' and YAGNI philosophy, recommending patterns only when there are at least two concrete use cases currently present in the code.

Can it identify anti-patterns?

Yes, the skill includes a specific module for common mistakes and guidance on when NOT to use specific design patterns.

Does it provide implementation examples?

Yes, it includes 10 production-ready code examples across various real-world scenarios to demonstrate practical application.

Which design patterns are included in this skill?

The skill includes all 23 Gang of Four (GoF) patterns, categorized into Creational, Structural, and Behavioral patterns.

Learning & Documentation

Provides pragmatic architectural guidance on Gang of Four design patterns to build maintainable software while avoiding over-engineering.

About

The Design Patterns Expert skill is a comprehensive knowledge base for all 23 Gang of Four design patterns, integrated directly into your development workflow. It follows a 'simplicity first' philosophy, helping developers recognize when a pattern is necessary and when it might lead to architectural bloat. By utilizing progressive disclosure, the skill offers everything from quick reference definitions to deep-dive implementation strategies and anti-pattern warnings. Whether you are refactoring legacy code or architecting a new system, this skill ensures your patterns serve the code rather than complicating it.
