When to Use This Skill

Use this skill when the user provides a URL from one of these services and wants to read or summarise its content:

• A YouTube video URL (to fetch the transcript)
• A Twitter / X post URL
• A Bluesky post URL

For more complex pages requiring JavaScript rendering or authentication, use the agent-browser skill instead.

How to Fetch Content

Always run via a subagent to keep the main conversation context clean.

nix run github:ryoppippi/tgrab -- <url>

Examples

# YouTube transcript
nix run github:ryoppippi/tgrab -- https://www.youtube.com/watch?v=dQw4w9WgXcQ
