Does this skill help with CQRS?

Yes, it provides distinct interfaces for Write Repositories (for commands) and Query Repositories (for reads) to optimize data operations.

How does this skill handle application time?

It implements an IClock interface pattern to avoid direct dependencies on DateTime.Now, allowing for deterministic testing and better auditability.

What DDD patterns does this skill support?

This skill covers Aggregates, Entities, Repositories, Unit of Work, CQRS, and the Command pattern using the Paramore.Brighter library.

Is this compatible with Entity Framework Core?

Yes, the implementation patterns include specific details like protected parameterless constructors and private backing fields designed for EF Core materialization.

API Development

Implements production-grade Domain-Driven Design (DDD) patterns and clean architecture principles for robust .NET applications.

This skill provides Claude with a comprehensive framework for implementing Domain-Driven Design (DDD) in .NET environments. It focuses on creating maintainable, testable, and loosely coupled systems by enforcing patterns such as Aggregate Roots, Entities, and Repository-driven CQRS. By leveraging these standards, developers can isolate domain logic from infrastructure, ensure business invariants are maintained, and implement deterministic testing through specialized time-control patterns, all based on proven real-world production implementations.
