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

• Potentially malicious external URL detected (high risk: 0.90). The skill instructs adding and using the MCP server endpoint https://rube.app/mcp at runtime (and to call RUBE_SEARCH_TOOLS to fetch current tool schemas), so remote content from that URL can change the agent's tool schemas and thereby directly control prompts/instructions.
