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

• Potentially malicious external URL detected (high risk: 0.80). The skill requires connecting at runtime to Rube MCP (https://rube.app/mcp) and explicitly calls RUBE_SEARCH_TOOLS to fetch current tool schemas which directly determine the agent's available instructions and tool behavior, so this external endpoint can control prompts.
