A polished English demo web app (Next.js + TypeScript + TailwindCSS) that simulates an agentic RPG-to-Spring modernization pipeline.

• Two-pane UX: RPG editor + tabbed insights (Agent Pipeline, Project Tree, File Viewer)
• Six migration agents with explicit INPUT/OUTPUT JSON and status
• DeepSeek wrapper with live mode and deterministic mock fallback
• Lightweight RAG snippet retrieval based on mapping rules
• Spring Boot artifact generation (layered architecture) + docs outputs
• Copy actions, loading skeletons, toast notifications, and ZIP download

npm install
npm run dev

Copy .env.example to .env.local and set:

DEEPSEEK_API_KEY=

If no API key is provided, the app remains fully functional in mock mode.
