The Agent Builder in xpander.ai is a powerful, visual tool that empowers developers to design, configure, and deploy intelligent AI Agents capable of autonomously performing complex tasks. Read more in Core Concepts section

Agent Builder basics

The most basic concept you should familiarize yourself with when using the AI Agent builder is the way that the automatic Action Graph system works. The Agent Builder screen is split into two parts:

  • The Chat interface on the left. Use the interface to chat with your Agent so it automatically builds the Action Graph System. Essentially, after selecting Connectors and functions that are enabled in your Agent, prompts in the Chat interface are sent to the Agent Builder, and it in turn builds the Graph System.
  • The Graph System interface on the right. The Graph System is generated automatically as you chat to your Agent in the Chat interface. Prompts in the Chat interface are sent to the Agent Builder (visually, it is using the Workbench Source Node, see more below) which automatically builds the Action Graph system.

​
Agent Builder views

The Agent Builder screen has two modes:

  • The Builder view is where you build your AI Agent by prompting the Chat interface and automatically constructing the Agent Graph system.
  • The Activity view is where you can see logs, metrics, traces and analytics about the use of your agent.

​
Enabling Operations and Functions for your AI Agent

When building your agent, you configure which Operations (stemming from Connectors) and Functions it is able to execute. You can edit the selection at any time. The selected Operations and Functions are essentially the list of Tools that the Agent will use when running. They also behave as a closed world of tools that the Agent Builder will select from when prompted through the Chat interface.

Basic steps to start building your AI Agent

Follow these steps to select Operations and Functions, and start building the Agent Graph:

  1. In the AI Agents screen, click “Create”
  2. In the Agent Builder screen, click the + button
  3. Click the Connectors & Functions button
  4. Select which Operations and Functions you would like your AI Agent to have access to
    You may first need to Enable Connectors from the Connectors screen
  5. Use the Chat interface in the Agent builder to send prompts and start automatically building the Agent Graph system for your AI Agent.

In the next pages of the user guide, you’ll learn about Graph paths and Prompt groups, as well as connect to your agent externally and trigger it.
