Media Ingest Skill

Ingest video, audio, PDF, book, screenshot, and GitHub repo content into the brain.

Filing rule: Read skills/_brain-filing-rules.md before creating any new page.

Contract

This skill guarantees:

• Every ingested media item has a brain page with analysis (not just a transcript dump)
• Transcripts (video/audio) saved in raw and human-readable formats
• Entity extraction: every person and company mentioned gets back-linked
• Raw source files preserved via inbrain files upload-raw
• Filing by primary subject, not by media format

Convention: See skills/conventions/quality.md for Iron Law back-linking.

Every mention of a person or company with a brain page MUST create a back-link.

Phases

Phase 1: Identify format and fetch

Format	Action
YouTube/video URL	Fetch transcript (Whisper, transcription service, or captions)
Audio file	Transcribe with available STT service
PDF	Extract text (OCR if needed)
Book PDF	Extract text, identify chapters/sections
Screenshot/image	OCR via vision model, extract text and entities
GitHub repo	Clone, read README + key files, summarize architecture

Phase 2: Upload raw source

Save the original file for provenance: inbrain files upload-raw <file> --page <slug>

Phase 3: Create brain page

File by primary subject (not format). Use this template:

# {Title}

**Source:** {URL or file path}
**Format:** {video/audio/PDF/book/screenshot/repo}
**Created:** {date}

## Summary
{Key points, not a transcript dump}

## Key Segments / Highlights
{For video/audio: timestamped highlights. For books: chapter summaries.}

## People Mentioned
{List with links to brain pages}

## Companies Mentioned
{List with links to brain pages}

Phase 4: Entity extraction and propagation

For every person and company mentioned:

1. Check brain for existing page
2. Create/enrich if needed (delegate to enrich skill)
3. Add back-link from entity page to this media page
4. Add timeline entry on entity page

A media item is NOT fully ingested until entity propagation is complete.

Phase 5: Sync

inbrain sync to update the index.

Output Format

Brain page created with summary, highlights, and entity cross-links. Report to user: "Ingested {title}: {N} entities detected, {N} pages updated."

Anti-Patterns

• Dumping raw transcripts without analysis
• Skipping entity extraction ("I'll do that separately")
• Filing raw ingest by format (all videos in media/videos/) instead of by subject. Note: format-prefixed paths under media/<format>/<slug> ARE sanctioned for synthesized one-of-one output like book-mirror's media/books/<slug>-personalized.md. The anti-pattern is for raw ingest, not for sui generis synthesis. See skills/_brain-filing-rules.md "Sanctioned exception: synthesis output is sui generis."
• Not preserving raw source files
• Creating stub pages without meaningful content
