youtube-summarizer

Use this skill to turn video-first updates into fast, structured text.

Workflow

1. Run transcript extraction with scripts/extract_transcript.py.
2. Generate structured summary with scripts/summarize_transcript.py.
3. Return final markdown summary path and key highlights.

Commands

# 1) Extract transcript + metadata
python3 scripts/extract_transcript.py \
  --url "https://www.youtube.com/watch?v=VIDEO_ID" \
  --out-dir ./artifacts

# 2) Summarize
python3 scripts/summarize_transcript.py \
  --transcript ./artifacts/transcript.json \
  --out ./artifacts/summary.md

Output format

• One-paragraph overview at top
• Section breakdown with timestamps
• Key announcements
• Product launches
• Names mentioned
• Links/resources referenced
• Top 5 takeaways (only if duration > 30 minutes)

Edge-case policy

• No captions available: return explicit error and suggest fallback (manual summary).
• Auto-captions noisy: de-duplicate and compress repeated filler lines.
• Live streams/filler: reduce repetitive lines and prioritize high-information segments.

Notes

• Prefer human captions first; fallback to auto captions.
• Keep summaries concise and scan-friendly.
