Point Chief at the right kind of research
Most of the time Chief picks the right agents for you. But when you already know whether you want answers from outside your organization or from inside your own documents, you can call an agent by name right in your prompt. Mention @explorer for external web research, or @librarian for your internal knowledge base.Call an agent in your prompt

- Click into the prompt bar.
- Type @ where you want to reference an agent.
- Pick the agent from the menu that appears — @explorer (external/web) or @librarian (your documents).
- Finish writing your prompt around the mention. For example: @explorer find the latest funding rounds in our category.
- Send the prompt.
💡 Good to Know: The moment you add an agent mention, Chief’s router switches that prompt to Deep Intelligence mode automatically — that’s the mode the agents run in. You’ll see the mode change in the prompt bar.

When to call which agent
- @explorer — competitive intelligence, market context, current events, anything from the open web.
- @librarian — questions that should be answerable from your uploaded files, knowledge base, or transcripts.
Removing an agent mention
If you decide you don’t want the agent (or don’t want to run in Deep Intelligence), delete the @mention from your prompt before sending. Chief will switch back to a standard mode such as Automatic.FAQ

The @ menu also lists other references (like Expert Voices). Make sure you’re selecting an agent (@explorer or @librarian) from the list. Researcher and Planner aren’t summoned by name — Chief invokes those automatically.
It told me the agent requires Deep Intelligence and I couldn't send. What now?

Agent mentions run in Deep Intelligence, a paid-plan feature. To send on a free plan, click to remove the agent and switch to Automatic intelligence — or upgrade to Pro to keep the agent.

You can reference an agent to steer your prompt. If your request really needs both internal and external sources, you often don’t need to name both — describe the task and Chief coordinates the Explorer and Librarian (and the Researcher to synthesize them) for you.
