NotebookLM CLI (nlm)

What this skill carries — grep references/ for any subject the names below miss: !d=${CLAUDE_SKILL_DIR}; command -v skill-toc >/dev/null 2>&1 && exec skill-toc "$d"; s=$HOME/.claude/skills/plugin-utils/bin/skill-toc; [ -x "$s" ] && exec "$s" "$d"; echo "(skill-toc unavailable: references and scripts are NOT listed here — install the plugin-utils plugin, or start a new session so its bin/ reaches PATH)"

Manage Google NotebookLM notebooks, sources, notes, chat, and generated content (audio/video overviews, slide decks, apps, reports) via the nlm command-line tool.

Requires: nlm on PATH (nix-managed, built from upstream tmc/nlm). Install/update via cd ~/nix && nix run .#build-switch.

Check: command -v nlm || echo "MISSING: nlm CLI not installed"

IRON LAW: gate on nlm source list before believing an empty chat answer. With expired auth the two chat paths fail differently and NEITHER says "auth": nlm chat <id> "…" prints nothing and exits 0, and nlm generate-chat <id> "…" prints empty response from API; check 'nlm sources …' for source state. Only the non-chat commands surface exit-class=auth (exit 3). So an agent that runs only a chat command reads an auth failure as "the notebook has nothing on this topic" — measured 2026-08-23, and the likely cause of a 366-line Bluebook reference being written from style guides while its author believed the notebook had been consulted. Run nlm source list <id> and require exit 0 first; an empty chat answer is evidence of nothing until you have.
