RISK

Why counter_offer is rated Critical

Counter-offers in a financial negotiation context commit the agent to financial terms and obligations. On a platform handling payments, lending, and escrow, sending a counter-offer can bind the agent to financial agreements, making this a Financial category tool with high severity due to potential for unauthorized financial commitments.

From the tool's definition 'Send a counter-offer in an active negotiation' on a server described as 'Complete financial infrastructure for AI agents — payments, lending, escrow & more'
