Go Backend Clean Architecture

What it does

This skill enables Go backend agents to generate code strictly adhering to Clean Architecture principles, ensuring high maintainability and separation of concerns. It structures applications into distinct layers—domain, application, interface, and infrastructure—to decouple business logic from external frameworks and databases.

When to use it

• Building new enterprise-grade Go services requiring long-term scalability.
• Refactoring legacy monolithic codebases into modular, testable components.
• Creating projects where business rules must remain independent of database or UI implementations.
• Developing systems that need rigorous unit testing without external dependencies.

Key capabilities

• Enforces strict dependency direction: inner layers (domain) have no knowledge of outer layers (infrastructure).
• Generates repository interfaces in the domain layer, deferring concrete implementation to the infrastructure layer.
• Structures entities and use cases to isolate core business logic from framework-specific concerns like HTTP or SQL.
• Organizes project directories to reflect architectural boundaries rather than technical file types.

Example prompts

• "Generate a Go user service using Clean Architecture with a domain entity, use case, and repository interface."
• "Refactor this existing Go handler to move business logic into the application layer while keeping the domain pure."
• "Create a new module for order processing that strictly follows Clean Architecture separation of concerns."

Tips & gotchas

Ensure your agent understands that interfaces defined in inner layers must be implemented by outer layers; reversing this breaks the architecture. This approach increases initial setup complexity compared to standard MVC patterns, so it is best suited for projects prioritizing long-term structural integrity over rapid prototyping.
