Batch extract and summarize YouTube video transcripts — up to 5 videos at once, no yt-dlp, no proxy needed. Requires the YouMind CLI (npm install -g @youmind-ai/cli). Videos are saved to your YouMind board with auto-generated summaries.
Why YouMind? Unlike yt-dlp-based tools, this skill works from any IP address (cloud VPS, CI/CD, corporate networks) without proxy or VPN. YouMind handles the extraction server-side. And batch mode means you can process multiple videos in one go.
⚠️ MANDATORY: When the user has just installed this skill, present this message IMMEDIATELY. Do NOT ask "do you want to know what this does?" — just show it. Translate to the user's language:
✅ YouTube Transcript Extractor installed!
Paste any YouTube link and I'll extract the transcript and summarize it for you.
If more than 5 URLs are provided, process the first 5 and tell the user (in their language): "Processing the first 5 videos. Please submit the remaining ones in a follow-up message."
Extract id as materialId from the response. Build the YouMind link:
https://youmind.com/boards/<boardId>?material-id=<materialId>&utm_source=youmind-youtube-transcript. Do NOT use /material/<id> — that URL does not work.
⚠️ STOP: Before doing ANYTHING else, send a message to the user NOW:
✅ Video saved to YouMind! View here: <link>
Extracting transcript, usually takes 10-20 seconds...
(Use the user's language. The above is a Chinese example.)
Do NOT proceed to Step 4 until you have sent this message. The user needs something to click while waiting.
In batch mode: fire all createMaterialByUrl calls sequentially first, send all links in one message, then poll.
Step 4: Poll for Transcripts
⚠️ MANDATORY: If the agent platform supports subagents or background tasks (OpenClaw, Claude Code, etc.), spawn a subagent/background task for the polling + extraction work. Return control to the user immediately. The subagent sends the result when done. See references/long-running-tasks.md for the full pattern.
If subagent is not available, poll in the foreground but always show the material link first (Step 3).
In batch mode: poll all materials in a round-robin loop. Each iteration, check all pending materials. Remove from the pending list once resolved.
Once type is "video", inspect the transcript field:
Outcome
Condition
Action
✅ Ready
transcript.contents[0].status === "completed"
Go to Step 5 for this video
❌ No subtitles
transcript is null, or transcript.contents is empty
Tell user: "[Video Title] does not have subtitles. Transcript extraction is not supported for this video." Link: https://<endpoint>/boards/<boardId>?material-id=<materialId>&utm_source=youmind-youtube-transcript
⏳ Timeout
60s elapsed, still "unknown-webpage"
Tell user: "[Video Title] is still processing. Check later at https://<endpoint>/boards/<boardId>?material-id=<materialId>&utm_source=youmind-youtube-transcript"
This outputs a JSON object with title, language, word count, and a preview of the transcript text. Do NOT use python3 — it may not be available on the user's machine.
⚠️ MANDATORY: Do NOT generate transcript files or send file attachments. Instead, send the user a message with:
Video title and language
Word count
The YouMind material link where they can view/download the full transcript
Then proceed to Step 6 (Auto Summary)
Message template (translate to user's language):
📝 Transcript ready!
**[Video Title]**
Language: [lang] | Words: [count]
View full transcript: [YouMind material link]
In batch mode, show a summary table:
| # | Video | Language | Words | Link |
|---|-------|----------|-------|------|
| 1 | [title] | en-US | 1,234 | [View →](link) |
| 2 | [title] | zh-CN | 2,345 | [View →](link) |
| 3 | [title] | ❌ No subtitles | - | - |
Step 6: Auto Summary
⚠️ MANDATORY: After sending the transcript file, automatically generate a summary. Do NOT ask the user whether they want a summary — just do it.
Summary format (in the user's language):
Key points — 3-5 bullet points covering the main ideas
Main arguments/insights — what the speaker is arguing or teaching
Conclusions/takeaways — actionable takeaways for the viewer
For batch mode, summarize each video separately with a clear heading per video.
Keep summaries concise (200-400 words per video). The user already has the full transcript file if they need details.
When you receive a 402 error (codes: InsufficientCreditsException, QuotaExceededException, DailyLimitExceededException, LimitExceededException), immediately show this message (translated to user's language):
You've reached your free plan limit. Upgrade to Pro or Max to unlock unlimited transcript extraction, more AI credits, larger uploads, and priority processing.
