This skill provides expert guidance for applying Domain-Driven Design (DDD) tactical patterns to transform complex business requirements into clean, maintainable code. It helps developers move beyond anemic models by defining strict aggregate boundaries, enforcing domain invariants, and modeling immutable value objects. By focusing on behavior-rich domain objects rather than procedural controllers, it ensures that state transitions are handled via explicit domain events and repository contracts, leading to more resilient and scalable backend architectures.
