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

Build a handler layer using the Result Pattern to encapsulate business logic and coordinate repositories within a transactional boundary. All I/O operations use async/await with CancellationToken support to ensure safe asynchronous workflows.
The Result Pattern returns Result<T, Failure> instead of throwing exceptions, preserving original exceptions inside the Failure object. This approach provides clean error handling and maintains observability through integrated TraceContext without disrupting async execution flows.
Implement a handler layer to orchestrate business rules, validation, and repository interactions between controllers and data access. This enforces a clean separation of concerns while supporting dependency injection and cancellation tokens for responsive backend services.
Yes, the handler pattern fully supports dependency injection and CancellationToken for asynchronous workflows. It applies to backend services requiring safe, async flow management with non-throwing error handling and integrated TraceContext observability.
Yes, coordinate multiple repositories within a transactional boundary using the Result Pattern to return Result<T, Failure>. This non-throwing approach preserves original exceptions for observability while maintaining clean separation between controllers and data access.
