Solutions

1. Run `opencli notebooklm open <notebook>` first, then `opencli notebooklm get`.
2. Ensure no other command navigated the shared session page between open and get.
3. Re-establish the adapter session if page state appears stale.

Example fix

// before
opencli notebooklm get   # no notebook open
// after
opencli notebooklm open "My Notebook"
opencli notebooklm get

const state = await getNotebooklmPageState(page);
if (state.kind !== 'notebook') {
  await runCli(['notebooklm', 'open', notebookId]);
}

const isNotebookOpen = (state) => state?.kind === 'notebook';

try {
  return await runCli(['notebooklm', 'get']);
} catch (e) {
  if (String(e.message).includes('No NotebookLM notebook is open')) {
    await runCli(['notebooklm', 'open', notebookId]);
    return await runCli(['notebooklm', 'get']);
  }
  throw e;
}

When it happens

Trigger: Calling `opencli notebooklm get` before any notebook was opened, after navigating to the NotebookLM home/list, or when the session was restarted and page state reset.

Common situations: Script assumes a notebook is still open from a previous step that failed or navigated away; concurrent commands changed the shared session page.
