Building agents

Testing & prompts

Two ways to find out what you have built: have the conversation, or read the instructions it was turned into.

Talking to it

The built-in tester holds a live conversation with the agent as currently saved, through your microphone, without placing a real call.

  1. Save first

    The tester runs the saved workflow, not the canvas in front of you.

  2. Open the tester

    Test in the toolbar.

  3. Have the conversation

    Speak as a caller would, including the awkward turns, an agent that handles the happy path is not yet finished.

A voice is required

Without a voice configured on the AI Agent node the tester cannot open, and says so rather than failing quietly.

What saving produces

Every save turns the graph into the prompt the agent actually runs on. It reads the nodes and their connections, expresses the structure as a diagram the model can follow, folds in each node's own configuration (prompts, variables, scripts) and writes the result, along with a preview you can read.

To see it without saving, open the Agent node's side panel and choose Update Prompt. It is worth reading before a campaign runs: the prompt is what the agent receives, and the canvas is only how you wrote it.

The layout is not decoration

The generated prompt carries a structured version of your workflow, which the model uses as its map of the conversation. How you arrange the graph changes how the agent behaves.
