## Workflow: Scaffold New Project

### 1. Gather Requirements

Ask for:
- **PROJECT_NAME**: Project directory name (kebab-case)
- **PROJECT_DESCRIPTION**: Brief description
- **INCLUDE_AGENTS**: Whether to include Azure AI Agents setup
- **INCLUDE_SEARCH**: Whether to include Azure AI Search setup

### 2. Create Project Structure

Follow this order:
1. **Root files**: `azure.yaml`, `.env.example`, `.gitignore`, `.pre-commit-config.yaml`
2. **Frontend**: Initialize with pnpm, Vite, React, Fluent UI, Tailwind
3. **Backend**: Initialize with uv, FastAPI, Pydantic, pytest
4. **Infrastructure**: Bicep templates for Container Apps
5. **CI/CD**: GitHub Actions workflow
6. **Documentation**: README with setup instructions

### 3. Verify Setup

```bash
# Frontend
cd src/frontend
pnpm install
pnpm dev        # Should start on :5173

# Backend
cd src/backend
uv sync
uv run fastapi dev app/main.py  # Should start on :8000

# Verify health endpoint
curl http://localhost:8000/api/health
```

## Key Patterns

### azure.yaml with Remote Build

```yaml
name: ${PROJECT_NAME}
services:
  frontend:
    project: ./src/frontend
    host: containerapp
    language: ts
    docker:
      path: ./Dockerfile
      remoteBuild: true  # Build in Azure, not locally
  backend:
    project: ./src/backend
    host: containerapp
    language: python
    docker:
      path: ./Dockerfile
      remoteBuild: true
```

### Fluent UI Dark Theme

```typescript
// src/frontend/src/theme/brand.ts
import type { BrandVariants } from "@fluentui/react-components";

export const brandVariants: BrandVariants = {
  10: "#020305",
  20: "#111723",
  // ... full scale
  160: "#CDD8EF",
};

// src/frontend/src/theme/dark-theme.ts
import { createDarkTheme, type Theme } from "@fluentui/react-components";
import { brandVariants } from "./brand";

const baseDarkTheme = createDarkTheme(brandVariants);

export const darkTheme: Theme = {
  ...baseDarkTheme,
  colorNeutralBackground1: "#0a0a0a",
  colorNeutralBackground2: "#141414",
  // ... overrides
};
```

### FastAPI with Settings

```python
# src/backend/app/config.py
from pydantic_settings import BaseSettings

class Settings(BaseSettings):
    environment: str = "development"
    port: int = 8000
    frontend_url: str = "http://localhost:5173"
    azure_ai_project_endpoint: str = ""
    azure_ai_model_deployment_name: str = "gpt-4o-mini"

    class Config:
        env_file = ".env"

settings = Settings()
```

### Container App Bicep Module

```bicep
param name string
param location string = resourceGroup().location
param containerAppsEnvironmentName string
param targetPort int = 80
param env array = []

resource containerApp 'Microsoft.App/containerApps@2023-05-01' = {
  name: name
  location: location
  identity: { type: 'SystemAssigned' }
  properties: {
    managedEnvironmentId: containerAppsEnvironment.id
    configuration: {
      ingress: {
        external: true
        targetPort: targetPort
        transport: 'auto'
      }
    }
    template: {
      containers: [{
        name: 'main'
        image: 'mcr.microsoft.com/azuredocs/containerapps-helloworld:latest'
        resources: { cpu: json('0.5'), memory: '1Gi' }
        env: env
      }]
      scale: { minReplicas: 1, maxReplicas: 10 }
    }
  }
}
```

## Commands

```bash
# Initialize new project
mkdir ${PROJECT_NAME} && cd ${PROJECT_NAME}

# Frontend setup
cd src/frontend
pnpm install
pnpm dev

# Backend setup
cd src/backend
uv sync
uv run fastapi dev app/main.py

# Run tests
uv run pytest

# Azure deployment
azd auth login
azd up

# Deploy changes only
azd deploy
```

## Rules

✅ Use `remoteBuild: true` in azure.yaml for all services
✅ Use `DefaultAzureCredential` for Azure SDK authentication
✅ Use Fluent UI dark theme with custom brand tokens
✅ Use Pydantic v2 multi-model pattern for all API models
✅ Use async/await for all Azure SDK and database operations
✅ Include health check endpoint at `/api/health`
✅ Include CI workflow with lint, type check, and tests

🚫 Never hardcode credentials or endpoints
🚫 Never commit `.env` files
🚫 Never skip the verification step
🚫 Never use `localBuild` in azure.yaml (requires local Docker)
