🔴 Strict Execution Rule (Highest Priority)

Every instruction, step, and check in this SKILL.md must be followed exactly as written — no deviations allowed.

• Scripts must be actually executed: The youtube-upload.ts script must be run with all required parameters. Do not simulate or manually construct API calls.
• Steps must not be skipped or merged: Execute authentication, metadata sanitization, and upload in the defined order. Each step must succeed before the next begins.
• Checks must not be omitted: All metadata validation (title ≤100 chars, description ≤5000 chars, tags ≤500 chars) and upload verification must be fully executed.
• Config must be read from files: OAuth credentials and default settings must be read from the configured files. Do not hardcode.

YouTube Publisher

First time? If setup_complete: false above, run ./SETUP.md first, then set setup_complete: true.

Upload videos to YouTube with full metadata control.

Metadata sanitization

• > in title/description is automatically rewritten to 》
• < in title/description is automatically rewritten to 《
• Use this when YouTube rejects metadata because of special characters

Quick Start

cd ~/.claude/skills/youtube-publisher/scripts

# First time: authenticate
npx ts-node youtube-upload.ts --auth

# Upload video
npx ts-node youtube-upload.ts \
  --video /path/to/video.mp4 \
  --title "My Awesome Video" \
  --description "Check out this amazing content!" \
  --tags "tech,ai,tutorial" \

Authentication

First-time setup requires OAuth2 authentication:

1. Run npx ts-node youtube-upload.ts --auth
2. Browser opens Google login
3. Grant permissions to upload videos
4. Token is saved to .youtube-token.json

Token refreshes automatically. Re-run --auth if expired.

Environment

Create scripts/.env:

YOUTUBE_CLIENT_ID=your_client_id
YOUTUBE_CLIENT_SECRET=your_client_secret

Get credentials from Google Cloud Console:

1. Create project at console.cloud.google.com
2. Enable YouTube Data API v3
3. Create OAuth2 credentials (Desktop app)
4. Download and extract client_id & client_secret
