Go Interface Mastery
Implements robust Go abstractions and decoupling patterns using duck typing, interface composition, and standard library best practices.
The Go Interfaces skill empowers developers to leverage Go's unique implicit implementation system for creating flexible, testable, and maintainable software. It provides comprehensive patterns for interface design, ranging from basic definitions and composition to advanced architectural patterns like Dependency Injection, Strategy, and Adapters. By guiding users through the 'accept interfaces, return structs' philosophy and favoring small, focused method sets, this skill ensures Go code remains decoupled and adheres to SOLID principles while avoiding common pitfalls like over-abstraction or nil-interface confusion.
