How does this skill improve the Claude Code /design command?

It provides a specific rubric for the D (Design) step, ensuring Claude doesn't just write code but designs a robust domain model based on industry-standard DDD patterns.

Does this skill help with microservices architecture?

Yes, its Phase 2 focused on Bounded Contexts is specifically designed to help identify logical boundaries where services should be split.

When should I use the design-ddd skill?

You should use it when your domain has complex state transitions, more than three business rules, multiple entity invariants, or numerous 'cannot do' constraints.

What tactical design patterns does this skill cover?

It covers Ubiquitous Language, Bounded Contexts, Aggregates, Entities, Value Objects, Invariants, and Domain Events.

Guides the domain-driven design process by providing structured criteria for modeling complex business logic and system boundaries.

The design-ddd skill provides a comprehensive framework for Claude to execute Domain-Driven Design (DDD) during the architectural phase of software development. It specifically triggers during complex design tasks to help define Ubiquitous Language, establish Bounded Contexts, and implement tactical patterns like Aggregates, Entities, and Value Objects. By following this structured three-phase approach, the skill ensures that software architecture remains tightly aligned with business requirements while maintaining high levels of maintainability and scalability.
