YouTube Digest

Security checks across malware telemetry and agentic risk

Overview

This skill downloads and analyzes user-provided YouTube videos, and its network access and file creation are expected for that purpose.

Install only if you want an agent to fetch YouTube metadata/subtitles and create local briefing files. Use a dedicated output directory, review generated files before sharing, and install yt-dlp/ffmpeg from trusted package sources.

Lp3

Medium

Category: MCP Least Privilege
Confidence: 96% confidence
Finding: The skill instructs the agent to use shell commands, read and write local files, and access the network, but the skill metadata does not declare these capabilities or constrain their use. This creates a permission-transparency and least-privilege problem: operators may invoke the skill without realizing it can download remote content, write to arbitrary output paths, and execute external tools like yt-dlp and ffmpeg.

Missing User Warnings

Medium

Confidence: 84% confidence
Finding: The script performs outbound network requests to arbitrary YouTube URLs and writes fetched metadata, subtitle files, and transcripts to disk without any explicit user-facing notice or confirmation. In an agent skill context, these side effects can surprise users, leak access patterns through proxies, consume storage, or violate expectations around external access and local persistence.
