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 `gbrain 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: `gbrain 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

`gbrain 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
