Reference interaction
The create-order example is valuable because it combines account context, item selection, business rules, and fulfillment logic in one flow.
The example works as a proving ground because it is common and non-trivial. It requires the system to explain what can be ordered, what customer context is required, which delivery or pickup rules apply, and what hidden orchestration the server performs when the request is accepted. That makes it an ideal reference case for AIXE.
This kind of flow demonstrates real protocol work.
Non-trivial operation
The example is rich enough to expose how AIXE handles account context, item availability, pricing, delivery, and business constraints.
Teachable surface
It also demonstrates how a caller can discover the rules before or during execution instead of relying on prior memorization.
