Import local Zotero attachments into NotebookLM notebooks through notebooklm-mcp-cli (`nlm`). Use when Codex needs to find specific Zotero items by title, upload their local files to NotebookLM, default to PDF-only imports, include additional NotebookLM-supported formats when requested, auto-login to `nlm` if needed, shard notebooks at 50 files each, or avoid duplicate uploads on reruns.
