## ✨ Features

### 🤖 **AI-Driven Testing**
- **Smart Form Filling**: AI automatically fills forms with realistic test data
- **Batch Actions**: Efficient bulk operations for multiple elements (up to 5 actions per batch)
- **Context Awareness**: AI understands page state and avoids redundant actions
- **Loop Detection**: Prevents infinite testing cycles

### ⚡ **Batch Operations System**
- **Multi-Element Processing**: Execute up to 5 actions simultaneously
- **Intelligent Grouping**: AI automatically groups similar elements for batch processing
- **Performance Optimization**: Reduce API calls and execution time by 3-5x
- **Error Isolation**: Individual action failures don't stop the entire batch
- **Smart Prioritization**: Batch similar input types (text fields, checkboxes, etc.)

### 🎯 **Advanced Element Extraction**
- **XML Canvas Format**: Compact, efficient page representation (800x+ compression)
- **ID-Based Targeting**: Reliable element identification
- **Coordinate Mapping**: Precise click positioning
- **Real-time Updates**: Dynamic page state tracking

### 💰 **Token Economics & Cost Efficiency**
- **Massive Token Savings**: 800x+ data compression vs screenshots
- **AI Cost Reduction**: ~90% lower AI API costs compared to vision models
- **Text vs Vision Models**: Use cheaper text models instead of expensive vision APIs
- **Scalable Operations**: Process thousands of pages at fraction of screenshot costs
- **Performance Boost**: 10x faster processing with compact data format

### 📊 **Comprehensive Logging**
- **Action History**: Detailed logs of all AI decisions and actions
- **Form Data Capture**: Real-time extraction of filled form data
- **Performance Metrics**: Success rates, timing, and efficiency stats
- **Test Reports**: JSON and console output formats

### 🛡️ **Robust Automation**
- **Field Clearing**: Advanced input field cleaning before entry
- **File Upload Handling**: Programmatic file upload without OS dialogs
- **Error Recovery**: Graceful handling of failed operations
- **Stealth Mode**: Reduced bot detection signatures

## 💰 Cost Efficiency Analysis

### Token Usage Comparison

| Approach | Data Size | Tokens | Cost/Request | 
|----------|-----------|--------|--------------|
| **Screenshots** | 200KB | ~400,000 | $0.0048 |
| **XML Canvas** | 0.25KB | ~500 | $0.0001 |
| **Savings** | **800x smaller** | **800x fewer** | **48x cheaper** |

### Real-World Performance
- **Google Search**: 276KB screenshot → 3KB canvas = **92x compression**
- **GitHub Pages**: 166KB screenshot → 121KB canvas = **1.4x compression** 
- **Average Savings**: **~90% cost reduction** on AI API calls

## 🎮 Usage Examples

### AI-Powered Form Testing

```javascript
import { MCPAIInteractionAgent } from './test/ai-mcp-interaction-test.js';

const agent = new MCPAIInteractionAgent({
    maxIterations: 20,
    useMockAI: false,
    stopOnFailure: true
});

await agent.init();
await agent.runInteractionTest();
const report = await agent.generateReport();
```

### Batch Operations Example

```javascript
// Execute multiple actions in one batch
const batchResponse = await fetch('http://localhost:3001', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
        jsonrpc: '2.0',
        method: 'batch_actions',
        params: {
            actions: [
                { action: 'input_text', element_id: 'email', text: 'user@example.com' },
                { action: 'input_text', element_id: 'password', text: 'SecurePass123' },
