project-generator（项目生成器）

Project Generator Skill

Transform requirement documents or natural language descriptions into complete, production-ready full-stack applications with MANDATORY customizable tech stack selection.

⚠️ IMPORTANT: Tech stack selection is MANDATORY. Users cannot skip this step by pressing Enter. Each option must be explicitly selected or confirmed.

Capabilities

This skill generates:

• Backend: Java Spring Boot with proper layering (Controller, Service, Repository, Entity)
• Frontend: Vue 3 + TypeScript + UI component library
• Database: Entities with relationships, migration scripts
• API: RESTful endpoints with OpenAPI/Swagger docs
• Authentication: JWT-based auth (optional)
• Documentation: README, API docs, setup instructions

Interactive Tech Stack Selection

Before generating the project, the skill will guide you through selecting your preferred technology stack.

Selection Modes

Mode 1: Quick Selection (Mandatory)

⚠️ 此模式为强制模式，用户必须输入选择，不能回车跳过。

Use numbered options for rapid selection:

Best Practices

1. Review tech stack choices - Consider team expertise and project requirements
2. Start with defaults - Use proven combinations for quick prototyping
3. Database choice matters - MySQL for simple apps, PostgreSQL for complex queries
4. ORM selection - JPA for rapid dev, MyBatis for SQL control
5. Security - Enable JWT for production applications
6. Test locally - Use docker-compose for immediate testing

Troubleshooting

Database Connection Issues

• Verify selected database is running
• Check credentials in application.yml
• For H2: ensure spring.datasource.url uses correct mem/file path

Build Failures

• Ensure correct Java version is installed (17 or 21)
• For Gradle: check gradle wrapper version compatibility
• Verify Maven/Gradle can access dependencies

Frontend UI Issues

• Ensure selected UI library version is compatible with Vue 3
• Check if component imports match selected library
• Verify CSS preprocessor settings if using custom themes
