Implements Domain-Driven Design (DDD) tactical patterns to create robust, behavior-rich domain models with clear aggregate boundaries and enforced invariants.

This skill enables Claude to apply tactical Domain-Driven Design principles directly to your codebase, transforming simple data structures into sophisticated domain models. It guides the creation of immutable value objects, entities with distinct identities, and aggregate roots that maintain strict business invariants. By focusing on repository patterns and domain events, it ensures that business logic remains encapsulated within the domain layer rather than leaking into controllers or services, making systems significantly more maintainable and aligned with complex business requirements.
