​
Out-of-the-Box Behaviors (Summarized):

  • Speech pattern: Direct, concise, casual
  • Spells out symbols, acronyms, abbreviations, percentages, etc. ($4,000,000 -> “four million dollars”)|
  • Asks clarifying questions
  • Ends call when objective is complete or voicemail is detected

​
Prompting Tips:

  • Want to easily test out exactly how your agent will behave?
  • Aim for less than >2,000 characters where possible.
  • Simple, direct prompts are the most predictable and reliable.
  • Frame instructions positively:
    • "Do this" rather than "Don't do this"
    • Ex. “Keep the conversation casual” rather than “Don’t be too formal”.
    • This gives concrete examples of what to do, instead of leaving expected behavior open to interpretation.
