The editor has a built-in Test agent panel that lets you verify your agent’s behaviour without leaving the builder. The panel shows two options: Get call from agent (real outbound call) and Chat with agent (text simulation, no phone needed).

​
Opening the test panel

With nothing selected on the canvas, the inspector shows three tabs: Agent setup, Tools, and Test agent. Click Test agent.

​
Chat mode

Chat mode simulates a conversation with your agent as a text exchange. This is the fastest way to verify routing logic, node transitions, and prompt behaviour. How to use:
  1. With nothing selected on the canvas, click the Test agent tab in the inspector.
  2. Click Chat with agent.
  3. Type a message and press Enter to send it.
  4. The agent’s response appears in the chat panel, along with which node is active.
Set variable values in the Variables panel before starting a chat test. The test uses your variable values to substitute {tokens} in prompts and the welcome message.
Chat mode tests the text-level logic — prompts, routing, and transitions. It does not test TTS voice quality, STT transcription accuracy, or audio latency.

​
Call mode

Call mode initiates a real outbound call using the agent’s full configuration — TTS, STT, telephony, and all. How to use:
  1. With nothing selected on the canvas, click the Test agent tab in the inspector.
  2. Click Get call from agent, enter the phone number in E.164 format (e.g. +919876543210), and confirm.
  3. Answer the phone. The agent runs exactly as it would in production.
Call mode makes a real phone call and consumes telephony and LLM credits. Save the agent before starting a call test so the call uses your latest changes.

What to check

Use the test panel to verify:
  • The welcome message sounds right with your variable values filled in.
  • Routing transitions fire correctly — the agent moves to the expected node when you say what each condition describes.
  • Rule (expression) transitions based on turn counts, time of day, or other built-in variables fire at the right moment.
  • Static nodes play the correct message.
  • Function tools are invoked on the right node.
  • Silence handling (Auto-replay on silence) behaves as expected.
