```

## Core Components

### 1. Server-side

#### a. Alert Generation Engine
- **Primary Function**: `generate_dynamic_alert(district, state)`
- **Purpose**: Generates comprehensive weather alerts for specific districts.

**Process Flow:**
1. **Village Selection**: Randomly selects a village from the district
2. **Coordinate Resolution**: Gets GPS coordinates for location
3. **Crop Intelligence**: Selects appropriate crop based on:
   - Current season (Kharif/Rabi/Zaid)
   - District crop preferences
   - Regional agricultural patterns
4. **Weather Data Collection**: Fetches weather data from APIs
5. **Alert Generation**: Creates weather-based alerts
6. **AI Enhancement**: Applies OpenAI analysis (if available)

**Example Usage:**
```python
alert_data = await generate_dynamic_alert("Patna", "Bihar")
```

#### b. Crop Calendar System

**Crop Definitions**
The system includes detailed crop calendars for major Bihar crops:
- **Rice (Kharif)**: June-July planting, October-November harvest
- **Wheat (Rabi)**: November-December planting, March-April harvest
- **Maize (Kharif/Zaid)**: Dual season crop
- **Sugarcane (Annual)**: February-March planting
- **Mustard (Rabi)**: October-November planting

**District Crop Mapping**
Each district has specific crop preferences:
```python
DISTRICT_CROPS = {
    'patna': {
        'primary': ['rice', 'wheat', 'potato'], 
        'secondary': ['mustard', 'gram'], 
        'specialty': ['sugarcane']
    },
    # ... other districts
}
```

#### c. Weather Integration

**Supported Weather APIs:**
- **Open-Meteo** (Primary): Free, reliable weather data
- **Tomorrow.io**: Professional weather services
- **OpenWeatherMap**: Popular weather API
- **AccuWeather**: Commercial weather data
- **Google Weather**: Google's weather services

**Weather Alert Types:**
- **Heavy Rain Warning**: >25mm rainfall expected
- **Moderate Rain Warning**: 10-25mm rainfall expected
- **Heat/Drought Warning**: High temperature + low rainfall
- **Cold Warning**: Temperature <10°C
- **High Wind Warning**: Wind speed >30 km/h
- **Weather Update**: Normal conditions

### 2. Client-side

#### A2A Communication Agents

**SMS Agent**
Creates concise SMS messages (160 characters max):
```python
def create_sms_message(alert_data):
    return f"BIHAR ALERT: {crop} in {location} - {weather_summary}"
```

**WhatsApp Agent**
Generates rich WhatsApp messages with emojis and formatting:
```python
def create_whatsapp_message(alert_data):
    return {
        "text": formatted_message,
        "buttons": action_buttons
    }
```

**USSD Agent**
Creates interactive USSD menu structures:
```python
def create_ussd_menu(alert_data):
    return {
        "menu": "CON Weather Alert...\n1. Details\n2. Actions"
    }
```

**IVR Agent**
Generates voice script for phone systems:
```python
def create_ivr_script(alert_data):
    return {
        "script": "Welcome to Bihar weather alert...",
        "menu_options": [...]
    }
```

**Telegram Agent**
Creates Telegram messages with inline keyboards:
```python
def create_telegram_message(alert_data):
    return {
        "text": message,
        "reply_markup": inline_keyboard
    }
```

- And 29 others...

## Deployment

### Local Development
```bash
python main.py
```
- FastAPI server: http://localhost:8000
- Gradio interface: http://localhost:7860

### Production Deployment

#### Docker Deployment
```dockerfile
FROM python:3.9-slim

WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt

COPY . .
EXPOSE 8000 7860

CMD ["python", "main.py"]
```

#### HuggingFace Spaces
The application automatically detects HuggingFace Spaces environment and configures accordingly:
```python
if os.getenv("SPACE_ID") or os.getenv("GRADIO_SERVER_NAME"):
    # HuggingFace Spaces mode
    fastapi_thread = threading.Thread(target=run_fastapi, daemon=True)
    fastapi_thread.start()
    demo.launch(server_name="0.0.0.0", server_port=7860)
```

## Troubleshooting

### Common Issues

#### 1. OpenAI API Key Missing
- **Error**: `OpenAI API key not found - AI features will be limited`
- **Solution**: Add `OPENAI_API_KEY` to `.env` file

#### 2. Weather API Failures
- **Error**: `Failed to get weather data`
- **Solutions**:
  - Check internet connectivity
  - Verify API keys in `.env`
  - Check API quotas and limits

#### 3. Geographic Data Issues
- **Error**: `District 'xyz' not found in Bihar`
- **Solutions**:
  - Use correct district spelling
  - Check district name in `BIHAR_DISTRICTS` list
  - Verify state parameter is "bihar"

#### 4. Import Errors
- **Error**: `ModuleNotFoundError: No module named 'tools'`
- **Solution**: Ensure all required modules are in the project directory:
  - `tools/`
  - `a2a_agents/`
  - `utils/`

### Logging and Debugging

#### Enable Debug Logging
```bash
export LOG_LEVEL=DEBUG
python main.py
```

#### Check Log Output
```python
logger.info(f"Selected village: {village}")
logger.error(f"Weather API error: {error}")
```

### Performance Optimization

#### 1. API Response Caching
Consider implementing Redis caching for weather data:
```python
# Pseudo-code
@cache.cached(timeout=300)  # 5 minute cache
async def get_weather_data(lat, lon):
    return await weather_api.fetch(lat, lon)
```

#### 2. Database Integration
For production, consider using PostgreSQL/MongoDB:
```python
# Store alert history
await db.alerts.insert_one(alert_data)
```

## Contributing

### Development Guidelines

#### 1. Code Style
- Follow PEP 8 Python style guide
- Use type hints for function parameters
- Add docstrings for all functions
- Maximum line length: 100 characters

#### 2. Testing
```python
import pytest

def test_crop_selection():
    crop = select_regional_crop("patna", "bihar")
    assert crop in ["rice", "wheat", "potato"]

async def test_weather_api():
    result = await open_meteo.get_current_weather(25.5941, 85.1376)
    assert "temperature" in result
```

#### 3. Documentation
- Update this documentation for new features
- Add inline comments for complex logic
- Create examples for new API endpoints

#### 4. Version Control
```bash
git checkout -b feature/new-weather-provider
git commit -m "Add new weather API integration"
git push origin feature/new-weather-provider
```

### Adding New Features

#### 1. New Weather Provider
```python
# tools/new_weather_api.py
async def get_current_weather(latitude, longitude, api_key):
    # Implementation
    return weather_data
```

#### 2. New Communication Channel
```python
# a2a_agents/slack_agent.py
def create_slack_message(alert_data):
    return {
        "text": message,
        "attachments": []
    }
```

#### 3. New Crop Types
```python
CROP_CALENDAR["new_crop"] = {
    "season": "Rabi",
    "planting": "December",
    "harvesting": "May",
    "duration_days": 150,
    "stages": ["Sowing", "Growth", "Harvest"]
}
```
