- **Error Recovery**: Graceful degradation and fallback mechanisms
- **Cross-platform**: Windows, macOS, Linux support
- **Multiple Interfaces**: CLI, Web UI, and Python API

## 🚀 Features

- ⚡ **Ultra-fast responses** - Template system provides <100ms responses
- 🎯 **High accuracy** - >90% quality scores with professional GRASS GIS guidance
- 📦 **Lightweight** - Optimized package size under 1GB
- 🧠 **Smart fallbacks** - Enhanced responses for edge cases
- 🔄 **Template-first** - Instant responses for common GRASS GIS operations
- 💾 **Offline capable** - Works without internet after initial setup
- 🌐 **Multiple interfaces** - CLI, Web UI, and Python API
- 🔧 **Cross-platform** - Windows, macOS, and Linux support

## 📦 Installation

### From PyPI (Recommended)

```bash
pip install grass-rag-pipeline
```

### From Source

```bash
git clone https://github.com/your-repo/grass-rag-pipeline.git
cd grass-rag-pipeline
pip install -e .
```

### System Requirements

- **Python**: 3.8 or higher
- **Memory**: 2GB RAM minimum, 4GB recommended
- **Storage**: 1GB free space for models and cache
- **OS**: Windows 10+, macOS 10.14+, or Linux

## 🚀 Quick Start

### Command Line Interface

```bash
# Ask a question
grass-rag --question "How do I calculate slope from a DEM?"

# Interactive mode
grass-rag --interactive

# Web interface
grass-rag-ui
```

### Python API

```python
from grass_rag import GrassRAG

# Initialize the pipeline
rag = GrassRAG()

# Ask a question
response = rag.ask("How do I import raster data into GRASS GIS?")
print(f"Answer: {response.answer}")
print(f"Confidence: {response.confidence:.3f}")
print(f"Response Time: {response.response_time_ms:.1f}ms")

# Batch processing
questions = [
    "Calculate slope from DEM",
    "Create buffer zones",
    "Export vector data"
]
responses = rag.ask_batch(questions)
```

### Configuration

```python
# Custom configuration
config = {
    "cache_size": 2000,
    "max_response_time": 3.0,
    "template_threshold": 0.9
}

rag = GrassRAG(config)

# Runtime configuration updates
rag.configure(cache_size=5000, template_threshold=0.8)
```

## 🏗️ Architecture

The pipeline uses a three-tier optimization strategy:

```mermaid
graph TD
    A[User Query] --> B{Template Match?}
    B -->|Yes| C[Template Response <100ms]
    B -->|No| D{Cache Hit?}
    D -->|Yes| E[Cached Response <10ms]
    D -->|No| F[Enhanced Fallback 1-2s]
    C --> G[Response with Metadata]
    E --> G
    F --> G
```

### Core Components

1. **Template System**: Instant responses for common GRASS GIS operations
2. **Multi-level Cache**: L1 (preloaded) + L2 (dynamic LRU) caching
3. **Enhanced Fallback**: Structured responses for edge cases
4. **Error Recovery**: Graceful degradation and error handling

## 📊 Performance Metrics
