Provides multiple methods with guided fallback chain (captions > Whisper > web services). Does NOT trigger for: watching videos, video editing, or non-transcript tasks.

Seed question: How do I get the transcript of this video?
Extract text transcripts from any video source. Platform-aware — detects what tools are available and guides to the best method.
Before extracting, determine available tools:
| Tool | Check | Best For |
|---|---|---|
youtube-transcript-api | pip show youtube-transcript-api | YouTube caption extraction (fastest) |
| MLX-Whisper MCP | Check .mcp.json for mlx-whisper | Apple Silicon local transcription (any video) |
| Whisper-cpp MCP | Check .mcp.json for whisper-cpp | Cross-platform local transcription |
Guide user to install what's missing for their platform if needed.
1. YouTube URL?
→ Method A: Caption extraction (youtube-transcript-api)
→ Fallback: Whisper if no captions available
2. Other video URL?
→ Check if platform provides captions
→ Fallback: Whisper transcription
3. Local video/audio file?
→ Method C: Whisper directly
→ Apple Silicon: MLX-Whisper (faster)
→ Other: Whisper-cpp

1. CHECK: Does video have existing captions?
→ Try youtube-transcript-api first (fastest, zero compute)
→ Check language availability
2. IF NO CAPTIONS: Use Whisper
→ Apple Silicon: MLX-Whisper MCP
→ Other: Whisper-cpp MCP
3. IF TOOLS UNAVAILABLE: Web services
→ youtubetotranscript.com
→ Manual from YouTube UI
4. PROCESS: Clean transcript
→ Remove timestamps if not needed (saves tokens)
→ Save to file for downstream analysis
Transcripts can be long. Strategies:
" ".join([t['text'] for t in transcript]) — saves ~30% tokensall_transcripts.md with --- separators| Issue | Solution |
|---|---|
| "Transcripts disabled" | Use Whisper transcription (Method B) |
| "Language not available" | Try auto-generated captions, or Whisper with task="translate" |
| "Rate limited" | Add delays between requests |
| "MCP not connected" | Restart Claude Code, check .mcp.json |
| "Long video truncation" | Use Whisper (no length limit) or chunk processing |
Activation (any of these):
--budget or -bbudget-mode skill is active in sessionWhen active:
Note: After context compaction, auto-detection may fail. Re-invoke budget-mode skill or pass --budget explicitly.
A vasana is a pattern that persists across unrelated contexts. If during
this task you notice such a pattern emerging, it may be worth capturing.
This skill works best alongside the vasana skill and vasana hook
from the Vasana System plugin.
