What is nblm CLAUDE.md?

A set of project rules for an AI coding assistant working on magicseek/nblm, a tool that asks Google NotebookLM questions and returns answers grounded in provided sources.

It guides repository changes, NotebookLM queries, authentication checks, notebook management, and other development work in the nblm project.

It keeps responses and project files in English and ensures NotebookLM is accessed through the repository’s own scripts. It also documents the approved commands for common development tasks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01925	$0.01925
Opus 5.5	$0.00770	$0.00770
Sonnet 5.5	$0.00385	$0.00385
Haiku 4.5	$0.00193	$0.00193

Security

Grade A, and why

nblm CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

⚠️ IRON RULE - English Output

Always respond in English. All code, documentation, comments, commit messages, and written output must be in English, regardless of the language used in user input.

⚠️ IRON RULE - NotebookLM Usage

When working in this repository and needing to reference or query NotebookLM, you MUST use the skill provided by this repo itself. Do not use external NotebookLM tools or services - always use the scripts and tooling defined here.

This is a non-negotiable project law.

Project Overview

nblm - enables AI coding agents to query Google NotebookLM for source-grounded, citation-backed answers. Uses the agent-browser daemon (Node.js) and a Unix socket protocol for automation.

Session Model: Stateless per question; the daemon keeps browser state in memory until it is stopped.

Development Commands

Running Scripts (Always use run.py wrapper)

# 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 - Will fail without venv:
python scripts/auth_manager.py status

The run.py wrapper automatically creates .venv, installs Python deps, and installs Node.js deps if needed.

Manual Environment Setup (if automatic fails)

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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
