Youtube Summary

Security checks across malware telemetry and agentic risk

Overview

This skill transparently fetches YouTube transcripts through TranscriptAPI and summarizes them, with normal dependency and privacy considerations but no evidence of hidden or harmful behavior.

Install only if you are comfortable using TranscriptAPI for transcript retrieval. Use a dedicated API key, expect video identifiers and transcript requests to leave your environment, keep requests and yt-dlp updated or pinned, and treat transcript text and custom summary instructions as untrusted summarization input rather than agent instructions.

MCP Least Privilege
Confidence
92% confidence
Finding
The skill declares no explicit permissions, yet its documented workflow clearly uses environment variables, shell execution, and outbound network access to a third-party transcript service. This creates a transparency and policy-enforcement gap: users or platforms may not realize the skill can access secrets and transmit video identifiers/transcript data externally.

Vague Triggers

Medium
Confidence
84% confidence
Finding
The README states the skill 'kicks in automatically' when a YouTube link is dropped in chat, but it does not clearly document the trigger boundaries or safeguards. Broad auto-activation can cause the agent to process unintended URLs or user messages, leading to unexpected third-party requests and transcript summarization without sufficiently explicit user consent.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The README explains that transcripts are extracted via TranscriptAPI.com, but it does not clearly warn users that video URLs and transcript-derived content are sent to a third-party service for processing. This creates a privacy and data-handling risk because users may assume summarization is local and unknowingly disclose viewing interests or sensitive transcript content to an external provider.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The high-level skill description says it summarizes YouTube videos, but it does not clearly warn that video data and transcript content are sent to TranscriptAPI.com, a third-party service. Users may reasonably assume processing is local, so this is a privacy/transparency issue that can lead to unintended external disclosure of watched content or transcript text.
