creating-services

What problem does it solve?

This skill helps developers create well-structured Python service classes following the Service Layer pattern, enabling clean separation between Core and Composite services and enforcing constructor-based dependency injection.

Core Features & Use Cases

• Create focused Core services with explicit dependencies injected via the constructor.
• Distinguish Core vs Composite services to orchestrate workflows without leaking infrastructure concerns.
• Provide guidelines for method organization, error handling, and testing boundaries.
• Real-world example: turning a business rule into a service class that coordinates domain models and repositories.

Quick Start

Define a new ServiceName class with constructor-based dependencies, implement a single business operation, and wire it into the Core layer of your project.
