# Full-stack app build prompt
FULLSTACK_PROMPT='Build a full-stack task management application with the following structure:

FRONTEND (Next.js 14 + shadcn/ui):
- Create a Next.js 14 app with App Router in /frontend
- Use shadcn/ui for all components (install with npx shadcn-ui@latest init)
- Dark theme with modern aesthetic
- Pages: Dashboard showing tasks, Add Task form, Task detail view
- Use Tailwind CSS for styling
- Connect to backend API at /api proxy

BACKEND (Go):
- Create a Go HTTP server in /backend using chi router
- Endpoints: GET /api/tasks, POST /api/tasks, GET /api/tasks/{id}, DELETE /api/tasks/{id}
- In-memory task storage (no database needed)
- Structured JSON responses
- CORS middleware for frontend

DOCKER:
- /frontend/Dockerfile: Multi-stage build for Next.js (node:20-alpine)
- /backend/Dockerfile: Multi-stage build for Go (golang:1.22-alpine)
- /docker-compose.yml: Run both services, frontend proxies to backend

CI/CD:
- /.woodpecker.yml: Build both images, push to registry, deploy to k8s

Create all necessary files including package.json, go.mod, and configuration files.'
