## What it's for

Guardrails and response guidelines are **strict** rules that your AI agent always respects. This is what makes the AI reliable and safe for your business: you stay in control of what it can and cannot say. You define them in the agent's **Settings** tab.

## Guardrails: the prohibitions

A guardrail tells the AI what it must **never** do. It is a safety barrier.

Examples of guardrails:

- "Never promise a refund."
- "Never give medical advice."
- "Never make up a price: if you don't know it, say you will check."

## Response guidelines: style and obligations

A response guideline tells the AI **how** to answer: its style, its phrasing, its obligations.

Examples of guidelines:

- "Always greet the customer by their first name."
- "Always end with: Have a great day!"
- "Answer in two sentences maximum."

## How to set them up

1. Open your agent in **AI Agents**.
2. Go to the **Settings** tab.
3. In the **Guardrails** field, write your prohibitions, **one per line**.
4. In the **Response guidelines** field, write your style obligations, **one per line**.
5. Save.

> 💡 **Tip** — Guardrails and guidelines are sent to the AI on every answer. So this is the ideal place for a rule that must *always* apply, whatever the customer's question.
