I noticed that there should be two types of response when user started a Name-free interaction and there are multiple skills that could response to this question:
type 1. Alexa response: "I think XXX skill could help you"/ "would you like to give XXX skill a try?"
type 2.Alexa just give the answer to user's question/command.
The thing is, it's hard to tell type2 from built-in intent. Do we really have type 2?
