# How the triage agent handles a ticket

A software company in Singapore lets an agent sort incoming support tickets before a person reads them. Every step and tool call is in the flow below.

```mermaid
agentflow TB
  flow triage["Triage agent"]
    ticket["New ticket"]@{ shape: input }
    classify["Classify topic and urgency"]@{ shape: task }
    search["search_known_issues"]@{ shape: tool }
    known["Known issue?"]@{ shape: decision }
    reply["Draft reply with the fix"]@{ shape: task }
    route["Route to a person"]@{ shape: task }

    ticket --> classify --> search --> known
    known --> reply
    known --> route
  end
```

A person approves every drafted reply before it is sent.
