MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.80). The skill explicitly requires calling RUBE_SEARCH_TOOLS against the external Rube MCP endpoint (https://rube.app/mcp) to fetch tool schemas and recommended execution plans which the agent must read and act on, so untrusted third-party content from that service could materially influence tool use and enable indirect instruction injection.

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

• Potentially malicious external URL detected (high risk: 0.80). The skill requires adding and calling the external MCP endpoint https://rube.app/mcp at runtime (via RUBE_SEARCH_TOOLS / RUBE_MANAGE_CONNECTIONS) to fetch tool schemas and recommended execution plans that directly control what the agent does, so this external URL is a runtime dependency that can control agent instructions.
