SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill ensures that the Usecase layer in a Go Clean Architecture project adheres to best practices for business logic orchestration, DTO transformations, error handling, and transaction management, preventing common architectural flaws.

Core Features & Use Cases

  • API Domain Validation: Verifies Usecase interfaces, Request/Response DTOs, and validation rules.
  • Usecase Implementation Review: Checks for correct CRUD patterns, error handling, and dependency injection.
  • DTO Transformation Guidance: Enforces inline DTO conversion and proper handling of optional fields.
  • Use Case: When developing a new feature, this Skill automatically audits the Usecase code to ensure it correctly handles business rules, interacts with repositories, and returns data in the expected format, catching potential bugs before they reach production.

Quick Start

Use the usecase-layer skill to review the Usecase implementation for the 'user' entity.

FAQPage Schema
How do I validate my Go Clean Architecture Usecase layer implementation?

You can validate your Usecase layer implementation by auditing API domain definitions, CRUD method patterns, and dependency injection. This Skill automatically reviews Usecase code to ensure correct business logic orchestration and adherence to Go Clean Architecture best practices.

What is the best way to handle DTO transformations in a Go Usecase layer?

The best way to handle DTO transformations in a Go Usecase layer is through inline DTO conversion. This approach enforces proper handling of optional fields and verifies Request/Response DTO validation rules to prevent common architectural flaws.

How do I check if my Go Usecase code follows correct error handling and transaction boundaries?

You can check error handling and transaction boundaries by auditing Usecase implementation patterns and repository interactions. This Skill verifies that your Go business logic correctly orchestrates transactions and handles errors before reaching production.

Can I use this code review tool for existing Go Clean Architecture projects?

Yes, you can use this code review tool for existing Go Clean Architecture projects. It audits Usecase interfaces, validates API domain definitions, and verifies repository interaction patterns to catch potential architectural bugs in your current implementation.

Why does my Usecase layer architecture fail to properly interact with repositories?

Your Usecase layer architecture may fail to properly interact with repositories due to incorrect CRUD patterns or flawed dependency injection. This Skill guides proper repository interaction and transaction boundaries to prevent architectural failures.
