I see—you're reporting that error message. Looking at the search results, it seems you tried to use a summarize command with a YouTube link.

The issue: Rafiki's !summarize command only works with Hive/InLEO thread links (inleo.io, peakd.com, hive.blog, ecency.com) — not YouTube URLs. That's why you got "No valid YouTube URL found."

What you can do instead:

• Share a transcript or article about the video
• Paste the video description or key points
