YouTube Skill

Work with YouTube videos — transcripts, search, and summaries.

Get Video Transcript

python3 -c "
from urllib.request import urlopen
import json, re

video_id = '{video_id}'
url = f'https://www.youtube.com/watch?v={video_id}'
html = urlopen(url).read().decode()

caption_match = re.search(r'"captionTracks":\[\{"baseUrl":"([^"]+)"', html)
if caption_match:
    caption_url = caption_match.group(1).replace('\\u0026', '&')
    caption_data = urlopen(caption_url).read().decode()
    texts = re.findall(r'<text[^>]*>(.*?)</text>', caption_data)
    transcript = ' '.join(t.replace('&amp;', '&').replace('&#39;', "'") for t in texts)
    print(transcript[:5000])
else:
    print('No captions available for this video')

Search Videos

curl -s "https://www.googleapis.com/youtube/v3/search?part=snippet&q=$(echo '{query}' | jq -sRr @uri)&type=video&maxResults=5&key={YOUTUBE_API_KEY}" \
  | jq '.items[] | {title: .snippet.title, videoId: .id.videoId, channel: .snippet.channelTitle}'

Guidelines

• Extract video ID from URLs: youtube.com/watch?v={id} or youtu.be/{id}
• When summarizing transcripts, organize by topic/section
• For long videos, note timestamps of key points
• If no captions are available, inform the user
