Or with the ClawHub CLI, for registry-managed skill folders outside a full OpenClaw workspace:
npx clawhub install yt-video-downloader
What This Skill Does
Downloads YouTube videos to local storage with control over quality and output format. Supports resolutions from 360p to 1080p, multiple container formats (MP4, WebM, MKV), and audio-only MP3 extraction. Uses yt-dlp, which the script installs automatically if not present.
Wraps yt-dlp with a straightforward CLI that handles installation and stream merging automatically, so users avoid manual yt-dlp configuration.
When to use it
- Save a tutorial video for offline viewing
- Extract audio from a music video as MP3
- Archive a lecture or conference recording
- Download a video in a smaller resolution to save disk space
- Grab a clip in WebM format for a web project
