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

• Potentially malicious external URL detected (high risk: 0.90). The skill instructs adding the MCP endpoint https://rube.app/mcp (SKILL.md:15), which is queried at runtime (via RUBE_SEARCH_TOOLS / RUBE_MANAGE_CONNECTIONS) to fetch tool schemas that directly control agent prompts and behavior, making it a runtime dependency that can change instructions.
