What problem does it solve?

Inconsistent endpoints and tangled logic lead to hard-to-test APIs. This Skill enforces a clean, layered approach (Routes → Middleware → Controllers → Services → Repositories → DTOs) to maintain clear responsibilities and type safety.

Core Features & Use Cases

• Layer Separation: Routes define endpoints, Middleware handles auth/validation, DTOs enforce payload shape
• DTOs & Type Safety: Use schemas to validate input/output
• Use Case: Implement a new user endpoint with strict separation and test coverage

Quick Start

Define a new route file under src/routes/v1, create a Create<User>Dto, implement a UserService, and wire up a UserController.
