notebooklm-mode

notebooklm-mode is a skill for Claude Code, Codex from moonlight-lupin/agent-skills. It costs 91 tokens per session (3,899 once invoked), scanned A, original, MIT.

A source-based research workflow inspired by NotebookLM, a tool for asking questions about documents you provide. It collects exact passages, searches them, and uses them to create grounded answers and deliverables.

In plain words
What is it for?
Use it to research a topic from a set of sources, answer cited questions, or create documents based on those sources in strict or augmented mode.
Why use it?
It reduces the risk of answers drifting away from the supplied material or mixing unsupported general knowledge into the result.

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.

Security

Grade A, and why

notebooklm-mode 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 12d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/ingest_source.py, scripts/parse_reference.py, tests/test_parse_reference.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

NotebookLM-Grounded Research Pipeline

Research a topic from sources — collect verbatim extracts, index them for semantic search, then answer questions and create deliverables grounded in those sources. Inspired by NotebookLM.

Trigger

  • User asks to research a topic "from sources" or "grounded in sources"
  • User mentions "notebooklm mode", "source-grounded", or "vault mode"
  • User wants responses that cite collected sources, not general knowledge
  • User asks to create deliverables from collected sources

Modes

Direct mode (default)

The orchestrator runs all roles inline — no subagents. Use for most topics.

Subagent mode (optional)

Spawn agents via delegate_task only when genuinely needed: parallel research across distinct sub-topics, or user explicitly requests it. Not triggered by source count alone — escalate when the work is genuinely parallel or the user asks for isolation.

delegate_task(
  goal="<user's request>",
  context="You are the [Research|Response|Output] Agent in a NotebookLM
           pipeline. Vault path: <vault_path>. Load skill 'notebooklm-mode'.
           Your role: [Research|Response|Output]. Topic: <topic>.
           Grounding mode: [strict|augmented].",
  toolsets=[<appropriate toolsets per role>]
)

Sequential: Research → (user reviews) → Response → (user requests) → Output. Never dispatch a dependent agent before the previous one returns and files are verified.

Grounding modes

Mode Behavior
Strict (default) Vault only. If it's not in the vault, you don't know it. Gaps are identified, never bridged with inference.
Augmented Vault first. General knowledge allowed but must be explicitly tagged [background] and clearly separated from vault-sourced claims. User requests this explicitly.

Augmented mode example:

According to Source #3: "The LTCI system covers 95% of seniors" [vault]

[background] LTCI was introduced in 2000 as part of Japan's long-term care insurance reform.

Changes

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.
