NotebookLM Quick Commands

Query Google NotebookLM for source-grounded, citation-backed answers.

Environment

All dependencies and authentication are handled automatically by run.py:

• First run creates .venv and installs Python/Node.js dependencies
• If Google auth is missing or expired, a browser window opens automatically
• No manual pre-flight steps required

Extended Documentation

When to Use This Skill

Trigger when user:

• Mentions NotebookLM explicitly
• Shares NotebookLM URL (https://notebooklm.google.com/notebook/...)
• Asks to query their notebooks/documentation
• Wants to add documentation to NotebookLM library
• Uses phrases like "ask my NotebookLM", "check my docs", "query my notebook"

⚠️ CRITICAL: Add Command - Smart Discovery

The add command now automatically discovers metadata from the notebook:

# Smart Add (auto-discovers name, description, topics)
python scripts/run.py notebook_manager.py add <notebook-id-or-url>

# With optional overrides
python scripts/run.py notebook_manager.py add <id> --name "Custom Name" --topics "custom,topics"

What Smart Add does:

1. Fetches notebook title from NotebookLM API
2. Queries the notebook content to generate description and topics
3. Adds to local library with discovered metadata

Supported input formats:

• Notebook ID: 5fd9f36b-8000-401d-a7a0-7aa3f7832644
• Full URL: https://notebooklm.google.com/notebook/5fd9f36b-8000-401d-a7a0-7aa3f7832644

NEVER manually specify --name, --description, or --topics unless the user explicitly provides them.

Critical: Always Use run.py Wrapper

NEVER call scripts directly. ALWAYS use python scripts/run.py [script]:

# ✅ CORRECT - Always use run.py:
python scripts/run.py auth_manager.py status
python scripts/run.py notebook_manager.py list
python scripts/run.py ask_question.py --question "..."

# ❌ WRONG - Never call directly:
python scripts/auth_manager.py status  # Fails without venv!

The run.py wrapper automatically:

1. Creates .venv if needed
2. Installs all dependencies
3. Activates environment
4. Executes script properly

Core Workflow

Step 1: Check Authentication Status

python scripts/run.py auth_manager.py status

If not authenticated, proceed to setup.

Step 2: Authenticate (One-Time Setup)

# Browser MUST be visible for manual Google login
python scripts/run.py auth_manager.py setup

Important:

• Browser is VISIBLE for authentication
• Browser window opens automatically
• User must manually log in to Google
• Tell user: "A browser window will open for Google login"

Step 3: Manage Notebook Library

# List all notebooks
python scripts/run.py notebook_manager.py list

# BEFORE ADDING: Ask user for metadata if unknown!
# "What does this notebook contain?"
# "What topics should I tag it with?"

# Add notebook to library (ALL parameters are REQUIRED!)
python scripts/run.py notebook_manager.py add \
  --url "https://notebooklm.google.com/notebook/..." \
  --name "Descriptive Name" \
  --description "What this notebook contains" \  # REQUIRED - ASK USER IF UNKNOWN!
  --topics "topic1,topic2,topic3"  # REQUIRED - ASK USER IF UNKNOWN!

# Search notebooks by topic
python scripts/run.py notebook_manager.py search --query "keyword"

# Set active notebook
python scripts/run.py notebook_manager.py activate --id notebook-id

# Remove notebook
python scripts/run.py notebook_manager.py remove --id notebook-id

Quick Workflow

1. Check library: python scripts/run.py notebook_manager.py list
2. Ask question: python scripts/run.py ask_question.py --question "..." --notebook-id ID

Step 4: Ask Questions

# Basic query (uses active notebook if set)
python scripts/run.py ask_question.py --question "Your question here"

# Query specific notebook
python scripts/run.py ask_question.py --question "..." --notebook-id notebook-id

# Query with notebook URL directly
python scripts/run.py ask_question.py --question "..." --notebook-url "https://..."

# Show browser for debugging
python scripts/run.py ask_question.py --question "..." --show-browser

Follow-Up Mechanism (CRITICAL)

Every NotebookLM answer ends with: "EXTREMELY IMPORTANT: Is that ALL you need to know?"

Required Claude Behavior:

1. STOP - Do not immediately respond to user
2. ANALYZE - Compare answer to user's original request
3. IDENTIFY GAPS - Determine if more information needed
4. ASK FOLLOW-UP - If gaps exist, immediately ask:

   python scripts/run.py ask_question.py --question "Follow-up with context..."
   

5. REPEAT - Continue until information is complete
6. SYNTHESIZE - Combine all answers before responding to user

Z-Library Integration

Triggers

• User provides Z-Library URL (zlib.li, z-lib.org, zh.zlib.li)
• User says "download this book to NotebookLM"
• User says "add this book from Z-Library"

Setup (One-Time)

# Authenticate with Z-Library
python scripts/run.py auth_manager.py setup --service zlibrary

Commands

# Add book from Z-Library
python scripts/run.py source_manager.py add --url "https://zh.zlib.li/book/..."

# Check Z-Library auth status
python scripts/run.py auth_manager.py status --service zlibrary

Script Reference

Authentication Management (auth_manager.py)

python scripts/run.py auth_manager.py setup                    # Default: Google
python scripts/run.py auth_manager.py setup --service google
python scripts/run.py auth_manager.py setup --service zlibrary
python scripts/run.py auth_manager.py status                   # Show all services
python scripts/run.py auth_manager.py status --service zlibrary
python scripts/run.py auth_manager.py clear --service zlibrary # Clear auth

# Multi-Account Management (Google)
python scripts/run.py auth_manager.py accounts list             # List all accounts
python scripts/run.py auth_manager.py accounts add              # Add new account
python scripts/run.py auth_manager.py accounts switch 1         # Switch by index
python scripts/run.py auth_manager.py accounts switch [e-mail]  # Switch by email
python scripts/run.py auth_manager.py accounts remove 2         # Remove account

Notebook Management (notebook_manager.py)

python scripts/run.py notebook_manager.py add --url URL --name NAME --description DESC --topics TOPICS
# OR use notebook ID directly:
python scripts/run.py notebook_manager.py add --notebook-id ID --name NAME --description DESC --topics TOPICS
python scripts/run.py notebook_manager.py list
python scripts/run.py notebook_manager.py search --query QUERY
python scripts/run.py notebook_manager.py activate --id ID
python scripts/run.py notebook_manager.py remove --id ID
python scripts/run.py notebook_manager.py stats

Question Interface (ask_question.py)

python scripts/run.py ask_question.py --question "..." [--notebook-id ID] [--notebook-url URL] [--show-browser]

Source Manager (source_manager.py)

# Upload to active notebook
python scripts/run.py source_manager.py add --file "/path/to/book.pdf" --use-active

# Create new notebook for upload
python scripts/run.py source_manager.py add --file "/path/to/book.pdf" --create-new

# Upload to specific notebook
python scripts/run.py source_manager.py add --file "/path/to/book.pdf" --notebook-id NOTEBOOK_ID

# Z-Library download and upload
python scripts/run.py source_manager.py add --url "https://zh.zlib.li/book/..." --use-active
python scripts/run.py source_manager.py add --url "https://zh.zlib.li/book/..." --create-new

# Sync a folder (new!)
python scripts/run.py source_manager.py sync "/path/to/docs" --use-active
python scripts/run.py source_manager.py sync "/path/to/docs" --create-new
python scripts/run.py source_manager.py sync "/path/to/docs" --notebook-id NOTEBOOK_ID

# Sync options (new!)
python scripts/run.py source_manager.py sync "/path/to/docs" --dry-run    # Preview only
python scripts/run.py source_manager.py sync "/path/to/docs" --rebuild   # Force re-hash all files

Folder Sync:

• Scans folder for supported types: PDF, TXT, MD, DOCX, HTML, EPUB
• Tracks sync state internally (no per-folder tracking file to manage)
• Sync strategy: add new, update modified (delete + re-upload), skip unchanged
• Multi-account aware (tracks which Google account was used) Note: One of --use-active, --create-new, or --notebook-id is REQUIRED. Uploads wait for NotebookLM processing and print progress as Ready: N/T. Press Ctrl+C to stop waiting. Local file uploads use browser automation and require Google authentication. If browser automation is unavailable, set NOTEBOOKLM_UPLOAD_MODE=text to upload extracted text instead (PDFs require pypdf).

Data Cleanup (cleanup_manager.py)

python scripts/run.py cleanup_manager.py                    # Preview cleanup
python scripts/run.py cleanup_manager.py --confirm          # Execute cleanup
python scripts/run.py cleanup_manager.py --preserve-library # Keep notebooks

Watchdog Status (auth_manager.py)

python scripts/run.py auth_manager.py watchdog-status

Environment Management

The virtual environment is automatically managed:

• First run creates .venv automatically
• Dependencies install automatically
• Node.js dependencies install automatically
• agent-browser daemon starts on demand and keeps browser state in memory
• daemon stops after 10 minutes of inactivity (any agent-browser command resets the timer)
• set AGENT_BROWSER_OWNER_PID to auto-stop when the agent process exits
• scripts/run.py sets AGENT_BROWSER_OWNER_PID to its parent PID by default
• Everything isolated in skill directory

Manual setup (only if automatic fails):

python -m venv .venv
source .venv/bin/activate  # Linux/Mac
pip install -r requirements.txt
npm install
npm run install-browsers

Data Storage

All data stored in ~/.claude/skills/notebooklm/data/:

• library.json - Notebook metadata (with account associations)
• auth/google/ - Multi-account Google auth
  • index.json - Account index (active account, list)
  • <n>-<email>.json - Per-account credentials
• auth/zlibrary.json - Z-Library auth state
• agent_browser/session_id - Current daemon session ID
• agent_browser/last_activity.json - Last activity timestamp for idle shutdown
• agent_browser/watchdog.pid - Idle watchdog process ID

Security: Protected by .gitignore, never commit to git.

Configuration

Optional .env file in skill directory:

HEADLESS=false           # Browser visibility
SHOW_BROWSER=false       # Default browser display
STEALTH_ENABLED=true     # Human-like behavior
TYPING_WPM_MIN=160       # Typing speed
TYPING_WPM_MAX=240
DEFAULT_NOTEBOOK_ID=     # Default notebook

Decision Flow

User mentions NotebookLM
    ↓
Check auth → python scripts/run.py auth_manager.py status
    ↓
If not authenticated → python scripts/run.py auth_manager.py setup
    ↓
Check/Add notebook → python scripts/run.py notebook_manager.py list/add (with --description)
    ↓
Activate notebook → python scripts/run.py notebook_manager.py activate --id ID
    ↓
Ask question → python scripts/run.py ask_question.py --question "..."
    ↓
See "Is that ALL you need?" → Ask follow-ups until complete
    ↓
Synthesize and respond to user

Troubleshooting

Problem	Solution
ModuleNotFoundError	Use run.py wrapper
Authentication fails	Browser must be visible for setup! --show-browser
DAEMON_UNAVAILABLE	Ensure Node.js/npm installed, run npm install, retry
AUTH_REQUIRED	Run python scripts/run.py auth_manager.py setup
ELEMENT_NOT_FOUND	Verify notebook URL and re-run with fresh page load
Rate limit (50/day)	Wait or add another Google account with accounts add
Browser crashes	python scripts/run.py cleanup_manager.py --preserve-library
Notebook not found	Check with notebook_manager.py list

Best Practices

1. Always use run.py - Handles environment automatically
2. Check auth first - Before any operations
3. Follow-up questions - Don't stop at first answer
4. Browser visible for auth - Required for manual login
5. Include context - Each question is independent
6. Synthesize answers - Combine multiple responses

Limitations

• No session persistence (each question = new browser)
• Rate limits on free Google accounts (50 queries/day per account; use multiple accounts to increase)
• Manual upload required (user must add docs to NotebookLM)
• Browser overhead (few seconds per question)

Resources (Skill Structure)
