### Tool changes

- 2026-11-12 `create_order` changed (inputSchema)
- 2026-11-04 `create_order` changed (description, annotations)
  - before: Creates an order and returns checkoutUrl, the page where the user pays. Nothing is charged by this call. Confirm the plan, activation and total with the user first. Returns orderId and orderToken for check_order.
  - after: Creates an order and returns checkoutUrl, the page where the user pays; nothing is charged by this call. Without confirm: true it only returns a preview with the price and creates nothing. Returns orderId and orderToken for check_order.
