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 using the MCP endpoint https://rube.app/mcp at runtime and then calls RUBE_SEARCH_TOOLS / RUBE_MULTI_EXECUTE_TOOL against that MCP to fetch tool schemas and execute remote tools, so this URL is a required runtime dependency that can control prompts and execute code.
