The skill largely matches its NotebookLM purpose, but needs review because it stores reusable Google session state, installs browser automation automatically, uses stealth-like browser settings, and has misleading download/help links.
Install only if you are comfortable with a local skill that installs Python packages and browser binaries, automates a logged-in Google session, stores reusable session cookies on disk, and may send your questions and notebook context to NotebookLM. Use a dedicated low-risk Google account, avoid the raw ZIP links unless independently verified, protect or delete browser_state/state.json when done, and do not use account rotation to bypass service limits.
