Sequential Pipelines and Handoffs

A customer writes to Desk: "My blender arrived broken, and I think you charged me twice." Two designs handle this message with the same three specialist agents, and they differ in a single decision.

In the first design, your code sends every message through three stages in the same order: investigate, decide, and reply. In the second, a triage agent, whose only job is to sort incoming messages, reads the message and transfers it to the billing agent. The billing agent later transfers it to the shipping agent, because it found a problem that it cannot resolve.
