  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 40 units, then message the manager (lee) 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":7}
  5. Turn 2Current stock is 7 units, so I need to order 33 to reach exactly 40. Since the supplier's system is unreliable, I'll use an idempotency key to guard against accidental duplicate orders.

  11. Turn 4The order actually went through despite the timeout — reference SUP-7033, 33 units, accepted. No retry needed. Now I'll message the manager.
