Customer-support agent

Overview

A support agent combines dialogue with safe tools and knowledge search to resolve requests. It may use a bounded loop or explicit graph.

Why this matters

Support often requires both explanations and current account information.

An everyday example

A service representative consults records and asks follow-up questions.

A technical example

Claim status tool plus policy RAG plus escalation.

How it works

1. Authenticate
2. Route
3. Retrieve/tool
4. Clarify
5. Validate response or escalate.

Architecture and flow

User → router/agent → safe tools + RAG → response/staff.

The insurance assistant example

Explain why a claim awaits an invoice without promising the eventual payout.

When to use it

Repetitive support requests with clear allowed outcomes.

When to avoid it

Complex disputes may require staff authority and review.

Interview answer

“I automate supported read/explanation tasks and make escalation and consequential writes explicit.”

Benefits, trade-offs, and production considerations

Evaluate resolution, wrong assurance, escalation quality, and repeat contact; fewer staff tickets alone is not a quality measure.
