The Sandbox is your agent’s control room and test chat in one. As its subtitle says, it’s where you “adjust your agent’s settings and preview responses in real time” — set the model, temperature, instructions, and chat options, then talk to your agent exactly the way a visitor would, with a live preview beside the settings. Open Agent → Sandbox from the agent sidebar.

Test your agent

1

Ask a real question

Type a question your knowledge base should answer.
2

Watch the answer stream

The agent replies in real time. While it works, you may see it thinking and using tools before the final answer appears.
3

Check the sources

Confirm the answer cites the right source from your knowledge base — that’s how you know it’s grounded in your content.
4

Adjust and retry

Tweak the model, temperature, or instructions, then ask again to compare.
Testing in the Sandbox is for your own iteration. Use it freely to dial in the agent before you embed it.

​
Tips

  • Test the hard questions — edge cases, ambiguous phrasing, and things just outside your content — to see how the agent handles them.
  • If an answer is wrong, check whether the source is Completed, then sharpen your instructions or add a Q&A.
  • To compare two full configurations at once, use the Playground.

​
Troubleshooting

Make sure a relevant source shows Completed in the Knowledge Base. If it does, add a closer-matching Q&A pair.
Refine your instructions and consider lowering temperature.
