Testing Agents
The Agent Builder includes a built-in test panel so you can try out your agent without leaving the builder.
How to Test
- Open an agent from the Agents landing page, or start a new one.
- Click Test agent in the editor header. A chat panel slides in beside the form.
- Type a message or question in the input field.
- Press Enter or click the send button.
- The agent's response streams in real time.
The panel sits alongside the form rather than covering it, so you can keep editing while you test. Drag its left edge to make it wider or narrower. Close it with the × in its header or by pressing Escape — reopening it later keeps the conversation.
What Gets Tested
Messages run against the configuration currently on the page — the model settings, attached tools, and attached instructions — including unsaved changes. You can adjust a setting and immediately see how it affects the response without saving first.
Because of that, a test result reflects your draft, not necessarily the saved agent. Save when you are happy with the behavior.
Tips for Testing
- Start simple. Try a basic question to confirm the agent responds correctly before testing edge cases.
- Test your trigger conditions. If you have tools with trigger conditions, try prompts that should and shouldn't activate them.
- Compare settings side by side. Send the same prompt at different Behavior or Verbosity settings to see how the output changes.
- Check instruction adherence. Ask the agent something that should be governed by your instructions and verify it follows the rules.
- Toggle Enhanced reasoning. If an agent struggles with a complex prompt, try the same prompt with Enhanced reasoning on before rewriting your instructions.
