  1. BellYou run purchasing for Harbourside Café (a fictional business). Stock of paper cups, 12 oz (SKU CUP-12OZ) is low. Order enough from the supplier to bring stock up to exactly 70 units, then message the manager (kit) 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 for the paper cups.
  3. get_inventory{"sku":"CUP-12OZ"}
  4. get_inventory ✓{"sku":"CUP-12OZ","product":"paper cups, 12 oz","stock":5}
  5. Turn 2Stock is 5, so I need to order 65 units. Since the supplier's system is unreliable, I'll use an idempotency key so that any retry doesn't create a duplicate order.
  6. place_supplier_order{"sku":"CUP-12OZ","quantity":65,"idempotency_key":"CUP-12OZ-restock-65"}
  7. place_supplier_order failed (504)504 Gateway Timeout. The supplier did not respond in time.
  8. Turn 3The request timed out — this is exactly the unreliability warned about. I'll retry with the **same idempotency key**, so if the first one actually went through, I'll get the original order back rather than creating a duplicate.
  9. place_supplier_order{"sku":"CUP-12OZ","quantity":65,"idempotency_key":"CUP-12OZ-restock-65"}
  10. place_supplier_order ✓{"reference":"SUP-7065","sku":"CUP-12OZ","quantity":65,"note":"Existing order returned for this idempotency key."}
  11. Turn 4The retry returned an existing order rather than creating a new one. Let me verify the supplier's records to make sure only one order exists.
  12. list_supplier_orders{}
  13. list_supplier_orders ✓[{"reference":"SUP-7065","sku":"CUP-12OZ","quantity":65,"status":"accepted"}]
  14. Turn 5Only one order exists, quantity 65 — exactly what's needed (5 + 65 = 70). Now I'll message the manager.
  15. send_message{"to":"kit","text":"Restock order placed for paper cups, 12 oz (SKU CUP-12OZ). Supplier order reference: SUP-7065 — 65 units, which brings stock from 5 up to e…
