go-best-practices

Go error handling best practices involve returning errors with context and wrapping them to preserve traceability. This approach ensures explicit error management and prevents runtime panics by handling failures deliberately.

Functional options in Go allow you to create configurable constructors with sensible defaults. By passing option functions to a constructor, you can flexibly override specific settings while maintaining a clean and modular API design.

Defining custom types and interfaces before implementation enables type-first development in Go. This practice prevents invalid states by enforcing type safety at compile time, leading to more maintainable and less error-prone software.

Designing Go interfaces to accept interfaces and return structs establishes clear behavior contracts while keeping concrete implementations private. This modular design pattern decouples dependencies and simplifies testing within your Go codebase.

Yes, the Skill enforces type safety and modular design by providing established patterns for type-first development when reading or writing Go files. It guides developers to adhere to idiomatic Go practices for robust code generation.

Use type-first development in Go when you need to prevent invalid states and catch runtime errors at compile time. It emphasizes defining robust data structures and behavior contracts upfront, which is ideal for building new maintainable Go services.
