How to Use (Claude Instructions)

Step 1: Extract Video ID

From URL patterns:

• https://www.youtube.com/watch?v=VIDEO_ID
• https://youtu.be/VIDEO_ID
• https://youtube.com/watch?v=VIDEO_ID&...
• Just VIDEO_ID (11 characters, alphanumeric with - and _)

Step 2: Run the Analyzer

python skills/cardiology/youtube-comment-analyzer/scripts/analyze_comments.py VIDEO_URL_OR_ID

Options:

• --max-comments 500 — Limit comments scraped (default: 500)
• --output path/to/file.json — Custom output location
• --json — Output raw JSON instead of formatted report

Examples:

# Analyze by URL
python skills/cardiology/youtube-comment-analyzer/scripts/analyze_comments.py "https://youtube.com/watch?v=abc123xyz"

# Analyze by ID with limited comments
python skills/cardiology/youtube-comment-analyzer/scripts/analyze_comments.py abc123xyz --max-comments 200

# Get JSON output
python skills/cardiology/youtube-comment-analyzer/scripts/analyze_comments.py abc123xyz --json

Step 3: Read the Output

The script outputs a formatted report directly. Full JSON is saved to:
