Concept & How It Works

    Why Does It Exist?

    Enterprise AI's most common production pattern — RAG + tools + guardrails + escalation. This capstone mirrors Zendesk/Intercom AI deployments.

    Real-World Analogy

    The best support rep who memorized the handbook and can pull up your order in two seconds — but calls a supervisor for refunds over $100.

    What is AI Customer Support Agent?

    Example

    Scenario

    Customer: 'Where is order #8821?' Agent verifies session, calls order API, replies with tracking link. Follow-up: 'Refund it' — policy allows <$50 auto; order is $120 → creates escalation ticket with full context for human.

    Solution

    In Capstone Projects, apply AI Customer Support Agent to this scenario: Customer: 'Where is order #8821?' Agent verifies session, calls order API, replies with tracking link. Identify the inputs, run the technique, validate the output, and note one thing you would monitor in production.

    Practice Task

    Do this before moving to the next module — reading alone is not enough.

    Open the Code Walkthrough below and run it locally. Change one parameter related to AI Customer Support Agent (e.g. model, temperature, top_k, or tool name), observe the difference in output, and write 2–3 sentences explaining what changed.
