Modern enterprise chatbots must do far more than repeat canned FAQ responses. Learn how to architect retrieval-augmented generation (RAG) agents that query live CRM records, verify account permissions, and automate tier-1 support tickets securely.
1. Authenticated Context Retrieval & PII Masking

3. Human-in-the-Loop Escalation Triggers
When confidence scores fall below threshold or customer sentiment indicates frustration, immediately hot-handoff the full conversation state to a live support engineer.
