Overview

This skill appears focused on extracting YouTube transcripts, with some documentation mismatch around Supadata and yt-dlp but no evidence of harmful behavior.

Before installing, verify which command actually runs and whether your environment uses Supadata, yt-dlp, or only the bundled YouTube scripts. Avoid using sensitive private or internal video URLs unless you are comfortable sharing the video ID and request metadata with YouTube or any configured transcript provider.

Missing User Warnings

Medium

• Confidence: 92% confidence
• Finding: The skill explicitly states it uses a third-party service (Supadata API) as the primary extraction method and references an API key, but it does not warn users that submitted YouTube URLs/video IDs may be transmitted to an external provider. This creates a privacy and data-handling transparency issue, especially if users assume processing is local or if the videos are sensitive, private, or organization-specific.
