Cancel group order using official SDK
AI agents call bitflow_cancel_group_order to permanently remove resources in Stacks AI MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling a group order is an irreversible action that destroys the order's active state and cannot be undone without creating a new order. In the context of DeFi trading on Stacks, this represents a destructive operation with financial implications. While it doesn't move funds directly (which would be Financial), it permanently modifies blockchain state by eliminating an order commitment.
From the tool's definition Tool name includes 'cancel' which is an irreversible operation that removes or nullifies an existing group order. The description states it 'cancel[s] group order' using the official SDK, indicating a destructive action on blockchain state.
