System Prompt
The system prompt defines your agent's persona, language, conversation flow, and constraints. It is the single most important setting for a natural, reliable voice agent.
What is the System Prompt?
The system prompt is the most important configuration for Myra. It is a set of instructions sent to the language model before every conversation begins — defining who the agent is, how it speaks, what it can and cannot do, and how it handles different caller scenarios.
Think of it as the employee handbook your AI reads before picking up every single call. It should cover the welcome behavior, language switching, variables, conversation flow, guardrails, pronunciation rules, handoff conditions, and the exact situations where the call is complete.
Note
How it works
You write the prompt
Configure persona, task, language rules, variables, business context, tools, and handoff behavior in one structured instruction set.
Injected before every call
When a call connects, Vomyra sends your system prompt to the language model as the first message, before any conversation starts.
Model follows the rules
The AI uses your instructions to shape every response — persona, tone, language, pronunciation, restrictions, call flow, and closing behavior.
Where to configure it
Navigate to Configuration → Model tab in your agent. The System Prompt field is below the Temperature and Max Token settings.
