Last verified: 2026-09-25. ## Agents, tasks, and the assistant | Today | What it is | Older or other names | In the API | | ------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------- | --------------------------------------- | | **Agent** | The assistant in the left sidebar that talks to your leads. It groups one or more tasks and holds their shared channels, schedule, instructions, and knowledge. | **Group** (classic interface and older guides) | `master_workflow`, `/master-workflows` | | **Task** | One job the agent does with a lead, end to end: its goal, stages, variables, and on/off switch. | **Agent** (classic interface and older guides); "mode" on a few screens | `workflow`, `workflow_id`, `/workflows` | | **Nexor AI** | The assistant for your team that builds and changes agents. The sidebar button is **Ask Nexor AI**, and its chat is titled **Nexor Agent**. | NexorGPT, Nexor Bot, "Do everything with Nexor AI" (classic launcher) | — | Some screens still say "agent" where they mean a task. For example, the stage option **Continue with another agent** chooses the next task, and **Pause this agent?** pauses one task. Nexor AI isn't one of your agents: your leads never talk to it. ## Setting up an agent | Today | What it is | Older or other names | | --------------------- | ---------------------------------------------------------------------------------------------------------- | ------------------------------------------------ | | **Instructions** | The agent's prompt: **What should it know?**, **What should it never do?**, **How to handle objections?** | Business rules, prompt | | **Knowledge Base** | The documents, websites, and texts your agents answer from. | Brain (Cerebro) | | **Library** | Files the agent can send to leads.
