NotebookLM Research Assistant Skill

Interact with Google NotebookLM to query documentation with Gemini's source-grounded answers. Each question opens a fresh browser session, retrieves the answer exclusively from your uploaded documents, and closes.

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

When user wants to add a notebook without providing details:

SMART ADD (Recommended): Query the notebook first to discover its content:

# Step 1: Query the notebook about its content

python scripts/run.py ask_question.py --question "What is the content of this notebook? What topics are covered? Provide a complete overview briefly and concisely" --notebook-url "[URL]"

# Step 2: Use the discovered information to add it

python scripts/run.py notebook_manager.py add --url "[URL]" --name "[Based on content]" --description "[Based on content]" --topics "[Based on content]"

MANUAL ADD: If user provides all details:

  • --url - The NotebookLM URL
  • --name - A descriptive name
  • --description - What the notebook contains (REQUIRED!)
  • --topics - Comma-separated topics (REQUIRED!)

NEVER guess or use generic descriptions! If details missing, use Smart Add to discover 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:

  • Creates .venv if needed
  • Installs all dependencies
  • Activates environment
  • 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

  • Check library: python scripts/run.py notebook_manager.py list
  • 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:

  • STOP - Do not immediately respond to user
  • ANALYZE - Compare answer to user's original request
  • IDENTIFY GAPS - Determine if more information needed
  • ASK FOLLOW-UP - If gaps exist, immediately ask:
python scripts/run.py ask_question.py --question "Follow-up with context..."
  • REPEAT - Continue until information is complete
  • SYNTHESIZE - Combine all answers before responding to user

Script Reference

Authentication Management ( auth_manager.py )

python scripts/run.py auth_manager.py setup    # Initial setup (browser visible)

python scripts/run.py auth_manager.py status   # Check authentication

python scripts/run.py auth_manager.py reauth   # Re-authenticate (browser visible)

python scripts/run.py auth_manager.py clear    # Clear authentication

Notebook Management ( notebook_manager.py )

python scripts/run.py notebook_manager.py add --url URL --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]

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

Environment Management

The virtual environment is automatically managed:

  • First run creates .venv automatically
  • Dependencies install automatically
  • Chromium browser installs automatically
  • 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

python -m patchright install chromium

Data Storage

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

  • library.json - Notebook metadata
  • auth_info.json - Authentication status
  • browser_state/ - Browser cookies and session

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

Rate limit (50/day)

Wait or switch Google account

Browser crashes

python scripts/run.py cleanup_manager.py --preserve-library

Notebook not found

Check with notebook_manager.py list

Best Practices

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

Limitations

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

Resources (Skill Structure)

Important directories and files:

  • scripts/ - All automation scripts (ask_question.py, notebook_manager.py, etc.)
  • data/ - Local storage for authentication and notebook library
  • references/ - Extended documentation:
  • api_reference.md - Detailed API documentation for all scripts
  • troubleshooting.md - Common issues and solutions
  • usage_patterns.md - Best practices and workflow examples
  • .venv/ - Isolated Python environment (auto-created on first run)
  • .gitignore - Protects sensitive data from being committed
