Just sharing a different perspective.
Most people think they have a different use case, and 95 percent of the time they do not. If I were to be more specific the only thing that might be different is your "tool/function call". I hope I am making sense. Unless you are doing some drive-thru voice assistant it is probably going to be close to what people already have.
Also you can go to any LLM bare minimum and tell it to create a template of Mary Dental for the restaurant industry.
Also everyone's core common elements are different - most do not even follow Vapi's prompting guide. If that was the case I understand you completely. Sadly it is not. (I am not even saying that is a bad either)
