# Agent Node

> Holds the prompt that drives one step of the conversation

An Agent node is one step of the conversation. Its prompt tells the agent what to do while the call sits on that node.

The edges leaving it are pathways. The model chooses between them based on how the conversation has gone, so each edge should describe the condition that sends the call down it.

## What you configure

**Prompt** — the instructions for this step. [Template variables](/talk/voice-agent/template-variables) work here.

**Variable extraction** — pull structured values out of what the caller said: a name, a budget, a confirmation. Each takes a name, type, and description.

**Tools** — [tools](/talk/voice-agent/tools/introduction) the agent can call while on this node.

**Knowledge base documents** — documents this step can draw on. See [Knowledge Base](/talk/voice-agent/knowledge-base).

**Allow interruption** — lets the caller cut in while the agent is speaking.

**Add Global Prompt** — on by default, prepending the [Global node](/talk/voice-agent/global) prompt to this one.

Most workflows have several Agent nodes, one per stage of the conversation.
