Error message

No NotebookLM notebook is open in the adapter session. Run `opencli notebooklm open <notebook>` first.

What it means

opencli notebooklm source-guide throws this EmptyResultError when the adapter session page is not currently on a notebook (state.kind !== 'notebook'). Source guides (FAQ/summaries per source) require an open notebook context, so the command fails fast before any listing.

Solutions

1. Run `opencli notebooklm open <notebook>` first, then retry source-guide.
2. Verify with `opencli notebooklm current` that a notebook is active.
3. Re-authenticate if the session bounced to home/login, then reopen the notebook.

Example fix

// before
opencli notebooklm source-guide --source "specs"
// after
opencli notebooklm open "Product Docs"
opencli notebooklm source-guide --source "specs"

const current = await exec('opencli notebooklm current --json');
if (!current?.id) { await exec('opencli notebooklm open "My Notebook"'); }
// then run source-guide

function isNotebookOpen(state) {
  return state?.kind === 'notebook' && typeof state?.notebookId === 'string' && state.notebookId.length > 0;
}

try {
  await run('opencli notebooklm source-guide', ['--source', name]);
} catch (err) {
  if (/No NotebookLM notebook is open/.test(err.message)) {
    await run('opencli notebooklm open', [notebook]);
    return run('opencli notebooklm source-guide', ['--source', name]);
  }
  throw err;
}

When it happens

Trigger: Running `opencli notebooklm source-guide` while the browser page is on the NotebookLM home screen, a non-NotebookLM URL, or an unrecognized page, i.e. after forgetting `opencli notebooklm open <notebook>` or after the tab navigated away.

Common situations: Fresh adapter session with no notebook opened; previous notebook tab closed or redirected; NotebookLM forced a return to home due to auth expiry so the /notebook/<id> URL was lost.
