  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 level of NAP-500.

  4. get_inventory ✓{"sku":"NAP-500","product":"napkins, pack of 500","stock":10}
  5. Turn 2Current stock is 10 units, so I need to order 30 units to reach exactly 40. Since the supplier's system is unreliable, I'll use an idempotency key to prevent duplicate orders.

  11. Turn 4The order actually went through despite the timeout — reference SUP-7030 for 30 units, status "accepted". I won't retry, as that would create a duplicate order. Now I'll message the manager with the reference.
