Security audit

Youtube Summary Skill

Security checks across malware telemetry and agentic risk

Overview

This skill does what it says: it fetches a YouTube transcript, summarizes it, and optionally saves a Markdown file.

Reasonable to install if you are comfortable with the skill running uv, downloading or using youtube-transcript-api at runtime, and contacting YouTube transcript endpoints for videos you provide. Review the helper script first if dependency downloads or outbound transcript requests are sensitive in your environment.

Finding
The skill invokes `uv` to install/use `youtube-transcript-api` and fetch YouTube transcripts, which necessarily performs outbound network access, but the skill metadata does not explicitly declare a corresponding permission. This creates a transparency and policy gap: users or security controls may underestimate the skill's external communication behavior, making review and enforcement harder.
