Never rely on training knowledge about what a specific video says.</li>\n<li><strong>Very long videos (&gt;2 hours):</strong> <code>youtube_video_transcripts_fetch</code> handles these fine. Only use <code>youtube_videos_read</code> on long videos if you specifically need AI-powered extraction — it can hit token limits on very long content.</li>\n<li><strong>No transcript available:</strong> Some videos have transcripts disabled.
