Why pm_cancel_all is rated Critical
This tool destroys active trading orders in bulk, which cannot be undone. While not involving fund movement itself, canceling all orders is a destructive financial action with high blast radius if triggered unintentionally by an AI agent—the user loses active market positions and any associated trading strategy. The 'all' parameter with no granular control amplifies severity.
From the tool's definition 'Cancel all active Polymarket CLOB orders' - this tool irreversibly cancels all active orders without reversal capability. The use of 'cancel all' indicates bulk destructive action on financial positions.
