A team of specialists, not a single answer

Explorer — your external intelligence operative

Librarian — your institutional memory, made searchable
The Librarian agent works exclusively inside your own content: uploaded documents, knowledge base, project files, and call transcripts. It surfaces the exact passage or data point you need, with citations back to the source document. Example: “What did we promise this customer about the renewal in our last QBR?” Librarian reads across your transcripts and notes and pulls the specific commitment, with a citation. You can call it directly by typing @librarian in your prompt.Researcher — the synthesis engine
The Researcher agent combines both worlds. It draws from your internal knowledge base and the open web at the same time, and is the agent Chief reaches for when a complete answer needs both what your organization knows and what the world knows. Example: “How do our retention numbers compare to industry benchmarks, and what should we change?” Researcher pulls your internal metrics (via the Librarian) and external benchmarks (via the Explorer) and delivers a unified, comparative answer. Chief invokes the Researcher automatically when a task calls for it.Planner — the architect of complex work
The Planner agent is the strategist. When a task is too big for one agent, the Planner breaks it into optimally sized subtasks, decides how many agents to deploy, and assigns each one its focus before work begins. Example: “Produce a full go-to-market plan for our new product.” The Planner decomposes that into market research, internal-data review, positioning, and roadmap subtasks, then dispatches the right agents to each. Chief invokes the Planner automatically for complex, multi-step requests. In the prompt bar’s @-mention picker, this agent is labeled Plan.💡 Good to Know: Explorer and Librarian are the two agents you can summon by name with @explorer and @librarian. Researcher and Planner run automatically when Chief decides a job needs them — you don’t have to call them.
