To design Go structs and interfaces for maintainability, apply composition, embedding, and interface segregation. This Skill provides actionable guidelines and patterns to structure your Go types effectively, ensuring your codebase remains testable and robust.

Interface segregation in Go programming involves defining small, client-specific interfaces rather than large monolithic ones. This Skill demonstrates how applying this pattern alongside type assertions prevents unnecessary dependencies and enhances code adaptability.

Using dependency injection with Go interfaces involves defining interfaces for dependencies and injecting concrete implementations at runtime. This Skill provides patterns for structuring types and interfaces to achieve loose coupling and improve testability.

Use struct embedding for direct field and method promotion, and composition for building complex types from smaller parts. This Skill offers best practices on struct design to help you choose the right approach for optimal code reuse.

Best practices for struct field tags in Go involve using them to define metadata for encoding, decoding, and database mapping. This Skill covers struct field tags as a core component of struct design, ensuring your types integrate cleanly with external systems.

Prior experience with Go programming is expected to apply these struct and interface patterns effectively. This Skill targets Go developers looking to enhance code quality and maintainability through dependency injection and interface design.
