Security audit

NotebookLM CLI

Security checks across malware telemetry and agentic risk

Overview

This skill is a transparent wrapper for the NotebookLM CLI, but it can operate on a logged-in NotebookLM account if the user runs those commands.

Install only if you trust the `notebooklm` CLI on your PATH and are comfortable letting an agent use your logged-in NotebookLM account. Require explicit confirmation before commands using `--yes`, deleting notebooks/sources/artifacts/notes, exporting content, changing collaborators, enabling public sharing, or changing language settings.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
This markdown file documents commands that delete notebooks, sources, artifacts, and notes, and also enables public sharing, but it provides no user-facing warning about data loss or exposure risks. Under the markdown-file criteria, safety-relevant behaviors that can affect user data or privacy should be accompanied by explicit warnings.

Natural-Language Policy Violations

Low
Confidence
88% confidence
Finding
The example `language set zh_Hans` directs use of a specific language/locale without indicating that it is optional or user-chosen. This can violate language/locale policy expectations when the skill appears to force a locale rather than offering a choice.
