## Why cancel_all_orders is rated Critical

This tool permanently cancels all pending orders without granular selection, representing a destructive operation with significant blast radius. While it requires a badge (access control mitigates risk somewhat), the action itself is irreversible and affects all pending orders at once. Not Financial because the tool doesn't move money or create obligations; it removes existing orders.

From the tool's own definition: "Tool name is 'cancel_all_orders' and description states it 'Cancel all pending orders' — this is an irreversible bulk deletion/cancellation action that cannot be undone."

## Use case

AI agents call cancel_all_orders to permanently remove resources in A2a Demos, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
