How does this skill help with ubiquitous language?

It provides frameworks for defining shared terminology that is used consistently across code, variable names, and business conversations, reducing translation errors between teams.

What is Domain-Driven Design (DDD)?

DDD is a strategic software design approach that focuses on modeling software to match the problem domain based on input from domain experts, prioritizing business logic over technical patterns.

What are Bounded Contexts in DDD?

Bounded Contexts are logical boundaries where a specific domain model is consistent and valid. They prevent global models from becoming bloated and inconsistent across a large system.

Is DDD suitable for simple CRUD applications?

Generally, no. DDD is best reserved for complex domains. For simple CRUD apps, DDD can be over-engineering; standard MVC patterns are usually more efficient.

When should I use the DDD skill with Claude?

Use this skill when dealing with complex business rules, designing microservices, or when your code structure no longer matches the terminology used by business stakeholders.

Models complex software systems by aligning code structure with business domains and establishing a shared ubiquitous language.

This skill provides expert guidance on Domain-Driven Design (DDD) to help teams bridge the gap between technical implementation and business requirements. It facilitates the creation of a ubiquitous language shared between developers and domain experts, identifies critical bounded contexts, and implements tactical patterns like Entities, Value Objects, and Aggregates. By focusing on the core domain logic rather than technical infrastructure, this skill helps developers build highly maintainable systems for complex industries like finance, healthcare, and logistics while preventing architectural degradation.
