Overview

This skill is a disclosed media-downloader helper that installs a pinned downloader CLI and performs expected URL fetching, local saving, parsing, and optional localhost WebUI use.

Install only if you trust the pinned npm package and your ffmpeg source. Use a dedicated downloads folder, avoid passing private cookies or authorization headers unless necessary, protect the optional WebUI with a strong secret, and confirm that downloads comply with site terms and applicable law.

Vague Triggers

Medium

• Confidence: 89% confidence
• Finding: The activation description is broad enough to trigger on many common user requests involving video/music URLs, which can cause the agent to invoke a downloader skill in situations where the user may only want metadata, discussion, or benign assistance. Because this skill performs network retrieval and can download external media, over-triggering increases the chance of unnecessary external access, policy-bypassing content acquisition, or misuse against untrusted URLs.
