How the agent uses knowledge, and how to test it
When a customer asks a question, the agent looks for the answer in its knowledge sources. You can check what it will find without making a call.
On the agent page click "Configure" and choose "Knowledge"
Click "Test a question"
Read the answer and where it came from
Under the answer you see its source, for example "From Pricing". This is the same lookup the agent runs in a real call.
What does the agent do when the knowledge has no answer?
At the bottom of the screen, next to "When the knowledge has no answer:", choose one of three options:

- "Knowledge only": the agent answers questions about the business only from the knowledge you added.
- "Balanced": your knowledge first, general knowledge only after it.
- "Free": the agent also answers freely from general knowledge.
