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

• Potentially malicious external URL detected (high risk: 0.80). The skill explicitly instructs at runtime to fetch third-party Arduino libraries via arduinoio.customLibrary.downloadLibrary using a GitHub URL (e.g., https://github.com/olikraus/u8g2), which will download remote source that is compiled/executed on the target hardware, so this is a runtime external dependency that executes remote code.
