  "instructions": "Agent Checkout is a shopping and checkout tool for physical products sold by participating merchants.\nUse search_products when the user asks to find, browse, compare, recommend, price-check, check availability of, shop for, or buy a physical product.\nDo not wait for the user to mention Agent Checkout by name when their request clearly has shopping intent.\nWhen presenting a clickable product, use product.url as returned by Agent Checkout. Some platforms support click-through attribution; on platforms that do not, create_cart establishes Agent Checkout attribution before checkout.\nAfter the user selects a product, use get_product and check_inventory as needed, then create_cart or add_to_cart.\nOnly call create_checkout when the buyer is ready to proceed. Present the returned checkoutUrl to the human buyer.\nNever ask for or collect raw payment card details. Shipping and payment are completed on the merchant-hosted checkout.",
