A comprehensive skill for creating new ddd4j (Domain-Driven Design for Java) projects based on ddd4j-boot framework. Use ONLY when the user explicitly mentions creating a ddd4j project, initializing ddd4j project, or setting up ddd4j-boot project. Supports three project types: single-module monolith, multi-module monolith, and microservices. Generates project scaffolding based on ddd4j-boot architecture with DDD, Hexagonal Architecture, Clean Architecture, and COLA V5 patterns. Do NOT trigger for generic DDD projects, JPA/Hibernate projects, or other ORM frameworks without explicit ddd4j mention.

It is built with Spring Boot 3.5.x and uses lightweight [ddd-4-java](https://github.com/fuinorg/ddd-4-java) and [cqrs-4-java](https://github.com/fuinorg/cqrs-4-java) libraries to implement Domain-Driven Design, Command Query Responsibility Segregation (CQRS), and Event Sourcing. ### Core Design Principles - **Domain-Driven Design (DDD)**: Strategic design through bounded contexts, tactical design with entities, value objects, aggregates, domain services, repositories, and domain events - **Command Query Responsibility Segregation (CQRS)**: Separation of read and write models, independent optimization - **Event Sourcing**: State changes recorded as event sequences, supporting comp
