A business example
A visitor asks about your opening hours in ordinary language. The assistant answers from approved business information and can ask whether a callback is wanted. It should not invent a holiday schedule missing from the source.
What to check in a real deployment
Separate understanding, answering and acting. The assistant may interpret a request without permission or capability to carry it out. Test each boundary explicitly and explain when a person must respond.
Apply the definition to a useful customer next step
Write down what the visitor should learn and what happens after the conversation. Check the approved source, optional contact purpose and receiving person responsibilities. A technical label is not evidence that a specific integration, quality guarantee or business result exists.
