handler

What problem does it solve?

This Skill provides a structured approach to implementing a consistent Handler layer that encapsulates business logic, coordinates across repositories, and applies the Result Pattern for error handling without throwing exceptions.

Core Features & Use Cases

• Business logic implementation: Encapsulates rules, validation, and orchestration across repositories.
• Error handling with Result Pattern: Returns Result<T, Failure> and preserves original exceptions for observability.
• Async execution and cancellation: All I/O operations use async/await with CancellationToken support.
• Cross-repository transactions: Coordinates multiple repositories within a transactional boundary when needed.

Quick Start

Use this skill to implement a Handler that coordinates two repositories within a transaction and returns a Result as the outcome.
