When should I use this DDD skill?

Use this skill for complex business domains with 5 or more entities that require strict logic enforcement and clear architectural boundaries. Avoid it for simple CRUD applications or small prototypes.

How does DDD improve AI-generated code?

It provides Claude with structured constraints that prevent 'anemic' models and 'leaky abstractions,' ensuring the AI generates code that separates business logic from database infrastructure.

What are the core building blocks included?

The skill covers Entities, Value Objects, Aggregates, Domain Services, Repositories, and Bounded Contexts.

Does this skill provide Python-specific patterns?

Yes, it includes production-ready Python implementations using features like frozen dataclasses for Value Objects and type-safe protocols for Repositories.

API Development

Implements tactical DDD patterns to model complex business logic through entities, value objects, and bounded contexts.

This skill equips Claude with the architectural patterns needed to tackle complex business domains using Domain-Driven Design (DDD). It provides standardized templates for creating rich domain models in Python, including immutable value objects, stateful entities with unique identity, and clean repository abstractions. By enforcing strict separation between domain logic and infrastructure, it helps developers build maintainable, scalable systems that utilize a ubiquitous language shared between code and business requirements. It is particularly effective for large-scale enterprise applications where maintaining data consistency and clear service boundaries is critical.

Key Features
