Parameters from the server's own tool schema.
Canceling an order is a destructive action that cannot be undone—once canceled, the order state changes permanently and the opportunity to fill at that price is lost. While not destructive in the data-deletion sense, it irreversibly modifies the state of a financial instrument (an open order) and commits financial consequences (preventing a potential trade execution).
From the tool's definition Tool name 'spot_cancel_order' combined with description 'Cancel an unfilled spot order' indicates irreversible cancellation of an active financial order on the OKX exchange.
