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

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

The skill contains instructions and code referencing external repositories (GitHub) and registries (PyPI mirror) for downloading and installing third-party tools/plugins like yt-dlp, bgutil-ytdlp-pot-provider, and yt-dlp-getpot-wpc during runtime setup, classifying them as common unofficial operational dependencies.
