Parameters from the server's own tool schema.
Cancelling an order is an irreversible action that destroys the current state of a financial order. While not technically deleting data from a database, order cancellation permanently terminates an active financial instruction that cannot be undone—the order ceases to exist in executable form. This qualifies as Destructive rather than Write (which is reversible) or Financial (which tracks money movement).
From the tool's definition Tool name 'swap_cancel_order' and description 'Cancel an unfilled SWAP/FUTURES order' indicate irreversible termination of a pending financial order on an exchange.
