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

• Potentially malicious external URL detected (high risk: 0.70). The skill auto-installs and imports yt-dlp at runtime via pip (fetching from PyPI, e.g. https://pypi.org/project/yt-dlp/), which downloads and executes remote code that the script then relies on, so this is a runtime external dependency that can execute code.
