Virtual Banker Implementation - Completion Summary

✅ All Integration Steps Completed

1. Service Integration ✅

• Orchestrator fully integrated with:
  • LLM Gateway (with conversation history)
  • RAG Service (document retrieval)
  • Tool Executor (banking tools)
  • ASR/TTS services

2. Banking Service Integration ✅

• BankingClient created for HTTP communication
• AccountStatusTool connects to banking API with fallback

   • Configure PixelStreaming

Testing

• Unit tests for services
• Integration tests for API
• E2E tests for widget

Production

• Secrets management
• Monitoring setup
• Scaling configuration
• Security hardening

🚀 Quick Start

# 1. Setup database
cd virtual-banker
./scripts/setup-database.sh

# 4. Create session
curl -X POST http://localhost:8081/v1/sessions \
  -H "Content-Type: application/json" \
  -d '{
    "tenant_id": "default",
    "user_id": "test-user",
    "auth_assertion": "test-token"
  }'
