What this skill does
Go Patterns This skill provides comprehensive Go patterns extending common design principles with Go-specific idioms. Functional Options Use the functional options pattern for flexible constructor configuration: Benefits: Backward compatible API evolution Optional parameters with defaults Self-documenting configuration Small Interfaces Define interfaces where they are used, not where they are implemented. Principle: Accept interfaces, return structs Benefits: Easier testing and mocking Loose coupling Clear dependencies Dependency Injection Use constructor functions to inject dependencies: Pattern: Constructor functions (New prefix) Explicit dependencies as parameters Return concrete types Validate dependencies in constructor Concurrency Patterns Worker Pool Context Propagation Always pass context as first parameter: Error Handling Error Wrapping Custom Errors Sentinel Errors Package Organization Structure Naming Conventions Package names: lowercase, single word Avoid stutter: user.User not user.UserModel Use internal/ for private code Keep main package minimal Testing Patterns Table-Driven Tests Test Helpers When to Use This Skill Designing Go APIs and packages Implementing concurrent systems Structuring Go projects Writing idiomatic Go code Refactoring Go codebases
