📝 Key Concepts

Conversation Context

The platform maintains conversation history for each client:

• Last 10 messages are tracked
• Conversation threads are identified by gaps > 24 hours
• Context is used by all AI agents for better understanding
• Prevents mixing old conversations with new ones

Lead Management

• New Opportunities: When a client contacts about a new property/need, a new lead is created (even if previous lead was closed)
• Lead Status: Tracks pipeline stages (NEW → CONTACTED → QUALIFIED → NEGOTIATION → WON/LOST)
• Automatic Linking: Messages from the same client are automatically linked to their lead

Persona Integration

• Persona characteristics are injected into all AI agent prompts
• Ensures consistent communication style across:
  • Inbox draft replies
  • Marketing content
  • Qualification suggestions
  • All broker-facing communications

Property Suggestions

• Properties are matched based on qualification brief
• Bedroom requirements inferred from conversation (e.g., "5 kids" → 5+ bedrooms)
• Best available matches are shown even if not perfect
• Informative messages explain match quality
• Studios (0 bedrooms) are included unless client needs bedrooms

🐛 Troubleshooting

Common Issues

1. Database Connection Errors

   • Verify SUPABASE_DB_URL in .env
   • Check database is accessible
   • Ensure migrations have run

2. OpenAI API Errors

   • Verify OPENAI_API_KEY is set
   • Check API key is valid and has credits
   • Review rate limits

3. WhatsApp Not Receiving Messages

   • Verify Twilio credentials
   • Check webhook URL is configured in Twilio
   • Ensure broker has connected WhatsApp number
   • Check backend logs for webhook errors

4. No Properties Found

   • Check property data exists in database
   • Verify search criteria aren't too restrictive
   • Review qualification brief extraction
