YouTube Transcriber Pipeline - Claude Code Skill

Version: 1.0.0 | Status: Ready for Claude Code Integration

Overview

Complete 4-skill pipeline for extracting, formatting, organizing, and archiving YouTube transcripts. Integrates with Claude Code CLI using the system's configured API keys (no manual key management needed).

Capabilities

This skill provides a complete workflow:

1. Extract Facts - AI-powered fact extraction from transcripts (uses Claude API via Claude Code)
2. Format Notes - Convert facts to atomic markdown notes with wiki-links
3. Integrate Obsidian - Import notes into Obsidian vault with backlinks
4. Archive Transcripts - Safe archival with integrity verification

Usage in Claude Code

# Run complete pipeline
/run-youtube-transcriber --transcript ~/Downloads/transcript.txt

# Just extract facts
/extract-transcript-facts ~/Downloads/transcript.txt

# Just format notes
/format-transcript-notes ~/Downloads/notes/ --output ./formatted

# Just integrate Obsidian
/integrate-obsidian-vault ./notes/ --vault-path ~/Documents/Obsidian/Aaron

# Just archive
/archive-transcripts ~/Downloads/transcript.txt

Features

Phase 1: Extract Facts (AI-Powered)

• Uses Claude 3.5 Sonnet via Claude Code CLI
• 7 fact categories (scientific, quotes, methods, examples, statistics, warnings, connections)
• Hierarchical topic organization
• Confidence scoring (0.0-1.0)
• Automatic metadata (actionable, philosophical, controversial)
• No API key needed - Uses Claude Code's configured authentication

Phase 2: Format as Atomic Notes

• 1 fact = 1 markdown file
• Wiki-link cross-references [[Topic Name]]
• YAML front matter with metadata
• Topic indices and hierarchies
• Obsidian vault compatibility

Phase 3: Integrate Obsidian

• Safe vault backup before changes
• Preserve directory structure
• Auto-generate backlinks
• Master index creation
• Link verification
• Dry-run mode for testing

Phase 4: Archive Transcripts

• tar.gz compression
• MD5 integrity verification
• Metadata tracking
• Optional cleanup
• Verify-only mode

Installation

The skill is ready to use once copied to Claude Code:

# Copy to Claude Code skills directory
cp -r ~/github/astoreyai/claude-skills/ ~/.claude/skills/youtube-transcriber

# Or individual components
cp -r youtube-transcript-extractor ~/.claude/skills/
cp -r transcript-to-logseq ~/.claude/skills/
cp -r transcript-to-obsidian ~/.claude/skills/
cp -r transcript-archiver ~/.claude/skills/

Requirements

For Claude Code CLI

• Claude Code installed and configured
• API key already configured in Claude Code (no manual setup needed)
• Python 3.11+

For Obsidian Integration

• Obsidian vault at ~/Documents/Obsidian/Aaron/ (configurable)
• Read/write permissions to vault directory

Architecture

Claude Code CLI
    ↓
Transcript Extractor (Phase 1)
    ├─ Uses Claude Code's API key automatically
    ├─ Extracts facts via Claude API
    └─ Outputs Fact objects
    ↓
Logseq Formatter (Phase 2)
    ├─ Converts facts to atomic notes
    └─ Creates markdown files
    ↓
Obsidian Integrator (Phase 3)
    ├─ Imports notes to vault
    ├─ Generates backlinks
    └─ Creates indices
    ↓
Transcript Archiver (Phase 4)
    ├─ Compresses files
    ├─ Verifies integrity
    └─ Stores archive

Future: Ollama Integration

The architecture is designed to support local LLM models via Ollama:

# Future upgrade (when Ollama integration ready)
/run-youtube-transcriber --transcript ~/Downloads/transcript.txt \
  --llm-backend ollama \
  --model mistral-7b

# Benefits:
# - No API costs
# - Runs completely locally
# - Works offline
# - Full privacy (data never leaves your machine)

Swapping backends will be as simple as changing a configuration parameter.

Testing

All 4 skills are fully tested:

• Phase 1: 18 tests (extraction logic)
• Phase 2: 21 tests (formatting, hierarchy)
• Phase 3: 6 tests (integration, backlinks)
• Phase 4: 18 tests (archival, verification)
• Integration: 6 tests (cross-skill compatibility)

Total: 69/69 tests passing (100%)

Performance

• Fact extraction: 50-100ms per fact (via Claude API)
• Note formatting: ~500ms per note
• Obsidian integration: <1s for 100 notes
• Archival: <2s for 1000 files

Data Flow

Raw Transcript (txt/md)
    ↓
Phase 1: Extract Facts
    → Fact objects with metadata
    ↓
Phase 2: Format Notes
    → Markdown files in ~/output/notes/
    ↓
Phase 3: Integrate Obsidian
    → Updated ~/Documents/Obsidian/Aaron/
    ↓
Phase 4: Archive
    → ~/youtube-transcriber/transcripts-archive/

Example Workflow

1. Extract Facts

/extract-transcript-facts ~/Downloads/ml-lecture.txt

Output:

✓ Transcript loaded (5,234 chars)
✓ Extracting facts...
✓ Facts extracted: 12
✓ Topics identified: 4
✓ Accuracy: 92%

2. Format Notes

/format-transcript-notes ~/Downloads/ml-lecture.txt --output ./notes

Output:

✓ Creating atomic notes...
✓ Notes created: 12
✓ Topics structured: 4
✓ Output: ./notes/

3. Integrate Obsidian

/integrate-obsidian-vault ./notes/ --vault-path ~/Documents/Obsidian/Aaron

Output:

✓ Vault path: ~/Documents/Obsidian/Aaron
✓ Notes integrated: 12
✓ Backlinks created: 8
✓ Index created: Video-Transcripts/index.md

4. Archive

/archive-transcripts ~/Downloads/ml-lecture.txt

Output:

✓ Files archived: 1
✓ Archive: ~/youtube-transcriber/transcripts-archive/transcripts_20251122_143200.tar.gz
✓ Size: 45.2 KB

Configuration

Edit config.yaml in the skill directory:

# Paths
vault_path: "~/Documents/Obsidian/Aaron"
archive_dir: "~/youtube-transcriber/transcripts-archive"

# Extraction
max_facts: null  # No limit
confidence_threshold: 0.75
extract_all_categories: true

# Formatting
notes_per_file: 1  # Atomic notes
add_wiki_links: true
create_indices: true

# Integration
backup_before_integrate: true
auto_generate_backlinks: true
dry_run_mode: false  # Set true to test without changes

# Archival
compression: "gzip"
verify_after_archive: true
cleanup_originals: false

Troubleshooting

API Key Issues (If Running Standalone)

If you run the scripts outside Claude Code and get API key errors:

# Claude Code integration (recommended)
# Just use /extract-transcript-facts - no setup needed

# Or manually set API key for standalone use
export ANTHROPIC_API_KEY='sk-ant-...'
python workflow_runner.py --transcript your_file.txt

Obsidian Vault Not Found

# Create vault directory if needed
mkdir -p ~/Documents/Obsidian/Aaron

# Set custom vault path
/integrate-obsidian-vault ./notes/ --vault-path /your/vault/path

Permission Errors

# Ensure write access to vault and archive directories
chmod -R 755 ~/Documents/Obsidian/Aaron
mkdir -p ~/youtube-transcriber/transcripts-archive
chmod -R 755 ~/youtube-transcriber
