AI Customer Support Agent

• Key points are in the visual diagram above.

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

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.

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.

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.

Highlighted lines show where AI Customer Support Agent happens in the code.

• Refunds without policy check
• KB without ACL per customer tier
• No sentiment-based escalation
