  This is a Shopify platform capability, not software ICON Aircraft wrote. It is recorded against
  ICON Aircraft because it is served from ICON Aircraft's own domain, is scoped to ICON's own
  merchant account (Shopify shop id 376732, "Shop ICON", Vacaville CA — ICON's headquarters), and
  operates exclusively on ICON's own catalog, carts and orders. It is the only agent-callable
  surface ICON Aircraft exposes; the corporate site at www.iconaircraft.com exposes none.

conventions:
  money: >-
    Every price in a tool response is an integer in ISO 4217 minor units paired with a currency
    code — {"amount": 2500, "currency": "USD"} is $25.00. Agents must convert before quoting.
  required_meta: >-
    Every tool requires a `meta.ucp-agent.profile` URI so the store can identify the calling agent.
  identifiers: Shopify global ids, for example gid://shopify/Checkout/abc123.
guardrails:
  - >-
    Checkout requires human approval. The store's published agent instructions state that agents
    must not complete payment without explicit, contemporaneous buyer consent, and forbid scripted
    form fills or end-to-end automation that finalizes payment.
  - The MCP endpoint is rate-limited per IP; back off on HTTP 429.
