What problem does it solve?

This skill helps backend teams enforce clean architecture, proper boundaries, and maintainable code, reducing technical debt and enabling faster, safer changes.

Core Features & Use Cases

• Layered architecture guidance: API, usecases, domain, infrastructure, config, and middleware.
• Validation and error-handling patterns: input validation at boundaries, domain errors, and HTTP mapping at the API boundary.
• Dependency injection and modularization: constructor injection, interface-based design, and testability.
• Use-case: Refactor a monolith into clear service boundaries to improve maintainability and testability.

Quick Start

Apply these guidelines to your backend project by mapping modules into the prescribed layered structure and validating inputs, errors, and dependencies.
