Implements Domain-Driven Design (DDD) aggregate patterns to manage consistency boundaries and business invariants in complex backend systems.

This skill provides production-ready patterns for designing aggregates within a Domain-Driven Design (DDD) framework. It guides developers in defining clear transactional boundaries, enforcing business invariants at the aggregate root, and optimizing aggregate size for performance. By standardizing how entities and value objects are grouped and accessed, it ensures data integrity across complex domains while avoiding common pitfalls like cross-aggregate object references and unbounded collections. It is particularly useful for backend architects building robust systems that require strong internal consistency.
