To refactor a monolithic service into fine-grained capabilities, break large services into smaller, single-responsibility units like separate gateway and fulfillment services. This isolates requirements during layer construction and enables flexible assembly.

Capability-based service design involves decomposing large services into smaller, focused units where each represents a distinct capability. This approach avoids monolithic structures by managing dependencies solely during layer construction.

To isolate service dependencies using Effect layers, manage requirements solely during layer construction. This ensures service operations do not leak their dependencies, maintaining strict separation and testability.

Breaking down services into capabilities improves testing by facilitating the isolated testing of individual capabilities. You can test each fine-grained unit independently without needing the entire monolithic service structure.

You should avoid capability-based design when your application does not require flexible capability assembly or isolated testing. If your service logic is small and tightly coupled, forcing decomposition adds unnecessary structural overhead.
