# DDD4j Project Creator

## When to use this skill

**CRITICAL: This skill should ONLY be triggered when the user explicitly mentions creating a ddd4j project, initializing ddd4j project, or setting up ddd4j-boot project.**

**ALWAYS use this skill when the user mentions:**
- Creating a ddd4j project (explicitly mentions "ddd4j")
- Initializing ddd4j-boot project
- Setting up ddd4j project structure
- Creating ddd4j project scaffolding
- 创建 ddd4j 项目 (explicitly mentions "ddd4j")
- 初始化 ddd4j 项目 (initialize ddd4j project)
- ddd4j-boot 项目创建 (create ddd4j-boot project)

**Trigger phrases include:**
- "创建 ddd4j 项目" (create ddd4j project) - **must include "ddd4j"**
- "初始化 ddd4j 项目" (initialize ddd4j project) - **must include "ddd4j"**
- "创建 ddd4j-boot 项目" (create ddd4j-boot project) - **must include "ddd4j"**
- "使用 ddd4j 创建项目" (create project using ddd4j)
- "ddd4j 项目脚手架" (ddd4j project scaffolding)

**DO NOT trigger this skill for:**
- Generic DDD projects without mentioning ddd4j
- JPA/Hibernate projects
- Other ORM frameworks
- Generic project initialization without ddd4j context
- "创建 DDD 项目" without "ddd4j" (too generic)
- "初始化项目" without "ddd4j" (too generic)

## About DDD4j Boot

**DDD4j Boot** is a Java microservice development scaffold based on **Domain-Driven Design (DDD)** principles. 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
