📖 **Detailed Guide**: See [./flowise-to-langchain/README.md](./flowise-to-langchain/README.md) for comprehensive documentation.

## 🔗 Flowise Integration (NEW!)

### Direct Flow Import
Import flows directly from your Flowise instance without manual export/upload:

```bash
# Start the web interface
cd testing-ui && npm run dev

# Configure your Flowise instance
# 1. Navigate to Settings → Flowise Configuration
# 2. Enter your Flowise URL (e.g., http://localhost:3000)
# 3. Add your API key for authentication
# 4. Test connection and save

# Browse and import flows
# 1. Go to Workspace → Flowise Integration
# 2. Browse available flows with search and filtering
# 3. Preview flow details and compatibility
# 4. Import single flows or bulk import multiple flows
```

### Features
- **Secure API Integration**: Encrypted API key storage
- **Flow Browser**: Search, filter, and preview flows
- **Bulk Import**: Import multiple flows simultaneously
- **Real-time Status**: Connection monitoring and health checks
- **Error Recovery**: Robust error handling with retry mechanisms

## 🔍 Observability & Monitoring

### Langfuse Integration
```bash
# Environment setup
export LANGFUSE_PUBLIC_KEY=your_public_key
export LANGFUSE_SECRET_KEY=your_secret_key

# Convert with Langfuse tracking
npm run start -- convert flow.json output --with-langfuse

# View traces in web interface
open http://localhost:3000/langfuse
```

### Performance Monitoring
```typescript
// Generated code with monitoring
import { performanceMonitor } from './monitoring/performance-monitor';

export async function runFlow(input: string): Promise<string> {
  const tracker = performanceMonitor.track('workflow.execution');
  
  try {
    const result = await agent.call({ input });
    tracker.measure('execution_time');
    return result;
  } finally {
    const snapshot = tracker.end();
    performanceMonitor.recordSnapshot(snapshot);
  }
}
```

## 🤖 Multiagent Examples

### Real-world Team Workflows
```bash
# Customer Support Team
npm run start -- convert examples/multiagent/customer-support/flowise/customer-support-agentflow.json output

# Software Development Team  
npm run start -- convert examples/multiagent/software-development/flowise/software-development-agentflow.json output

# Financial Analysis Team
npm run start -- convert examples/multiagent/financial-analysis/flowise/financial-analysis-agentflow.json output
```

### Generated Multiagent Code
```typescript
// Production-ready multiagent coordination
import { SupervisorAgent, WorkerAgent } from './agents';
import { performanceMonitor } from './monitoring';

export class CustomerSupportTeam {
  private supervisor: SupervisorAgent;
  private workers: WorkerAgent[];

async processInquiry(inquiry: string): Promise<string> {
    const tracker = performanceMonitor.track('team.inquiry');
    
    // Classify → Route → Respond → Escalate if needed
    const classification = await this.workers[0].classify(inquiry);
    const response = await this.supervisor.delegate(inquiry, classification);
    
    tracker.end();
    return response;
  }
}
```
