/install youtube-knowledge-extractor
Description
Multimodal YouTube video analysis through both audio (transcript) and visual (frame extraction + image analysis) channels. Especially powerful for HowTo vide...
Usage Guidance
This skill appears coherent and limited to downloading and analyzing YouTube content. Before installing, confirm you are comfortable with: (1) the skill downloading videos and writing temporary files to /tmp (potentially large disk/network usage), (2) network access to YouTube/captions endpoints, and (3) the source used to install yt-dlp — verify the 'uv' installer or install yt-dlp from a trusted package source yourself. Also consider copyright and terms-of-service implications for downloading videos and transcripts. If you need stricter controls, run the skill in an isolated environment or container.
Capability Analysis
Type: OpenClaw Skill
Name: youtube-knowledge-extractor
Version: 1.1.0
The OpenClaw skill 'youtube-knowledge-extractor' is classified as benign. All operations, including the use of `yt-dlp`, `ffmpeg`, `ffprobe`, `curl`, and embedded Python scripts, are directly aligned with its stated purpose of multimodal YouTube video analysis. The skill creates and cleans up temporary files in `/tmp`, and network requests are made to YouTube-related endpoints for video and subtitle data. There is no evidence of prompt injection attempting to subvert the agent's purpose, exfiltrate data, establish persistence, or perform other malicious actions. The instructions to the agent are detailed but focus on effective task execution within the skill's scope.
Capability Assessment
Purpose & Capability
Name/description (multimodal YouTube analysis) aligns with required binaries (yt-dlp, ffmpeg, python3, curl) and the described steps (download metadata/subtitles, download video, extract frames, analyze). The declared install (yt-dlp) is appropriate for the task.
Instruction Scope
SKILL.md contains explicit shell/python commands that operate only on a temp working directory, fetch YouTube metadata/subtitles via yt-dlp/curl, download the video, and run ffmpeg/ffprobe. It does not instruct reading unrelated system files, environment variables, or exfiltrating data to unexpected endpoints.
Install Mechanism
Install uses a 'uv' package entry to provide yt-dlp. Installing yt-dlp is expected, but 'uv' is an uncommon installer in this metadata — user may want to confirm the installer/source provenance for yt-dlp on their platform.
Credentials
No environment variables, credentials, or config paths are requested. Network access to YouTube/captions endpoints is required and consistent with the skill's purpose.
Persistence & Privilege
Skill is not always-enabled, does not request elevated privileges, and only writes artifacts to a temporary working directory under /tmp. It does not alter system or other-skill configurations.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install youtube-knowledge-extractor - After installation, invoke the skill by name or use
/youtube-knowledge-extractor - Provide required inputs per the skill's parameter spec and get structured output
