Instructions define your AI Voice Agent’s personality, behavior, and capabilities. Well-written instructions are crucial for creating effective AI Voice Agents.

​
What are Instructions?

Instructions are text prompts that tell your agent:
  • Who it is - Role and identity
  • How to behave - Personality and tone
  • What to do - Tasks and responsibilities
  • What not to do - Boundaries and limitations
