- BellYou run purchasing for Harbourside Café (a fictional business). Stock of napkins, pack of 500 (SKU NAP-500) is low. Order enough from the supplier to bring stock up to exactly 40 units, then message the manager (lee) the supplier's order reference. The supplier's system is known to be unreliable.
- Turn 1I'll start by checking the current stock of NAP-500.
- get_inventory{"sku":"NAP-500"}
- get_inventory ✓{"sku":"NAP-500","product":"napkins, pack of 500","stock":10}
- Turn 2Current stock is 10 units, so I need to order 30 to reach exactly 40. Since the supplier's system is unreliable, I'll use an idempotency key to guard against accidental duplicate orders.

- Turn 4The order did go through despite the timeout — reference SUP-7030, 30 units, accepted. Now I'll message the manager.
