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

• Potentially malicious external URL detected (high risk: 0.90). The skill requires adding https://rube.app/mcp as the Rube MCP server and explicitly instructs calling RUBE_SEARCH_TOOLS at runtime to fetch current tool schemas from that endpoint, so remote content from that URL can directly control available prompts/instructions and is a required dependency.
