go-best-practices

What problem does it solve?

This Skill enables Go developers to apply type-first design patterns, ensuring contracts are defined by types and interfaces before implementation, reducing bugs and enhancing maintainability.

Core Features & Use Cases

• Type-first design: Define domain types and interfaces prior to implementation to enforce clear boundaries.
• Functional options: Use configurable options to flexibly construct and compose components.
• Error handling & boundaries: Implement robust error propagation and boundary checks to improve reliability.
• Use Case: When designing a new Go package, apply these patterns to keep code modular, testable, and easy to evolve.

Quick Start

Define a User type and a UserID type, provide a constructor with functional options, and implement a simple repository interface to illustrate how the patterns fit together.
