  1. 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 60 units, then message the manager (dana) the supplier's order reference. The supplier's system is known to be unreliable.
  2. Turn 1I'll start by checking the current stock of NAP-500.
  3. get_inventory{"sku":"NAP-500"}
  4. get_inventory ✓{"sku":"NAP-500","product":"napkins, pack of 500","stock":3}
  5. Turn 2Current stock is 3 units, so I need to order 57 to reach exactly 60. Since the supplier's system is unreliable, I'll use an idempotency key to guard against accidental duplicate orders.

  8. Turn 3The supplier timed out — but a timeout doesn't necessarily mean the order failed. Let me check whether it was actually recorded before retrying.

  11. Turn 4The order went through despite the timeout — reference **SUP-7057**, 57 units, accepted. Checking first was important; a blind retry could have created a duplicate. Now I'll message the manager.
