Prompt Engineering
The practice of crafting instructions that guide an AI model toward desired behaviors.
Prompt engineering is the art and science of writing instructions that tell an AI model how to behave. For voice agents, the system prompt defines the agent's personality, conversation flow, qualification criteria, objection handling, and when to take actions.
A well-crafted prompt makes the difference between a robotic agent and one that feels natural and gets results. Key elements include clear role definition, specific instructions for common scenarios, and fallback behaviors for unexpected situations.
In Stellar, the system prompt is layered: base behavior, template-specific logic, knowledge base context, learned behaviors from past calls, and pipeline context.
