MEDIUM W009: Direct money access capability detected (payment gateways, crypto, banking).
- Direct money access detected (high risk: 1.00). The skill documentation explicitly features capabilities for executing paid API endpoints, sending transactions involving sBTC and STX tokens, and utilizing a configured wallet to handle payment flows automatically (including payment amounts and sponsored transactions for messaging).
