3. Configure the agent
Open Agent Config in the sidebar. This page defines who the AI agent is and how it should behave.
Persona name
The name the agent uses when greeting customers (e.g. Priya, Arjun, Maya, Support). Keep it short and consistent with your brand voice. Max 100 characters.
System prompt
The core instructions — max 10,000 characters.
A good system prompt:
- States clearly who the agent is and what business it represents.
- Describes the tone — formal, friendly, concise, etc.
- Lists what topics the agent should and should not discuss.
Do not put product details, prices, or FAQ content in the system prompt. Those belong in the Knowledge Base (next step) — the agent retrieves them automatically when relevant.
Example:
You are Priya, a customer support assistant for Acme Electronics.
You help customers with product questions, order status, and returns.
Be friendly, concise, and professional.
Always offer to connect the customer with a human agent if you cannot resolve their issue.
Do not discuss competitors or make promises about delivery timelines.Click the purple ✨ Generate with AI button above the textarea to open the System Prompt Generator wizard in the Vibot Assistant — it takes your free-form description and emits both a polished prompt and an opening greeting line.
Initial greeting (optional)
A short opening message used when starting a brand-new conversation. 600-character cap. Leave empty to fall back to the agent’s natural opener.
