MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The skill instructs agents to connect at runtime to the Square MCP Server endpoint https://mcp.squareup.com/sse, which streams model context (Model Context Protocol) and thus can directly control prompts/instructions provided to the agent.

MEDIUM W009: Direct money access capability detected (payment gateways, crypto, banking).

• Direct money access detected (high risk: 1.00). The skill is explicitly about integrating with Square's commerce APIs and mentions Payments/Checkout, payment-related webhooks (e.g., payment.created), OAuth token exchange, and API endpoints (connect.squareup.com/v2). Those are specific payment gateway APIs capable of creating/processing payments and thus constitute direct financial execution capability.
