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

• Potentially malicious external URL detected (high risk: 1.00). The skill declares and requires the Sketch MCP tool at http://localhost:31126/mcp which is invoked at runtime (run_code / get_selection_as_image) to execute JavaScript inside Sketch, so this external endpoint is a required runtime dependency that executes remote code.
