What is the difference between an Entity and a Value Object?

An Entity has a distinct identity that is tracked over time, while a Value Object is defined only by its attributes and is immutable.

When should I apply Domain-Driven Design?

Apply DDD when your project has intricate business rules, a long-lived lifecycle, and access to domain experts. It is ideal for systems where the domain provides a competitive advantage.

Can this skill help with Spring Boot implementation?

Yes, it provides the architectural foundation and integrates with specific Spring Boot skills to implement JPA repositories and domain events.

How does this skill help with Microservices?

It helps you identify bounded contexts where language changes, which serves as the most effective way to define service boundaries and ensure independent scalability.

API Development

Implements complex business logic and software architectures using strategic and tactical Domain-Driven Design principles.

About

This skill empowers Claude to act as a senior software architect specializing in Domain-Driven Design (DDD) to manage software complexity by aligning technical implementation with business reality. It provides comprehensive guidance for both strategic design—such as defining bounded contexts, subdomains, and context mapping—and tactical implementation of patterns like aggregates, entities, and value objects. By emphasizing ubiquitous language and architectural integrity, this skill helps developers decide between modular monoliths and microservices while ensuring core business logic remains isolated from infrastructure concerns.

Key Features

3 GitHub stars
Strategic design for identifying bounded contexts and subdomains

Ubiquitous language alignment between code and business stakeholders

Use Cases

Decomposing a large monolith into well-defined bounded contexts
Refactoring an anemic domain model into a rich, behavior-oriented architecture
Designing the architecture for a complex enterprise system from scratch
