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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly requires adding and calling the Rube MCP server at https://rube.app/mcp at runtime (via RUBE_SEARCH_TOOLS/RUBE_MANAGE_CONNECTIONS) to fetch current tool schemas that directly determine agent tooling and behavior, so this external URL can control prompts/instructions.
