# Define Your Agent's Behavior

> Adjust how your agent communicates and acts in every conversation.

Behavior is your agent's personality: how it greets people, what tone it uses, what it should achieve, and what it must never do. You set it up in your agent's **Behavior** tab.

## What you can define

Behavior is split into sections. These are the most important ones:

* **Identity & Goal** — who your agent is and what it should achieve in each conversation.
* **Welcome Message** — how it greets someone writing for the first time.
* **Response Style** — how long its replies are, its tone, and whether it uses emojis.
* **Process** — the step-by-step it should follow to help well.
* **Key Information** — facts it should never forget.
* **Do Not Do** — clear limits and rules for what it must not say or do.
* **Human Handoff** — when it passes the conversation to a person on your team.

## Two ways to set it up

    Tell Eva how you want your agent to work and it drafts it for you.

## Save your changes

When you're done, click **Save behavior**. If you have unpublished changes, Eva shows a banner with the **Publish changes** button.

<Tip>
  Be specific. Instead of "be friendly," write "greet them by name and offer help with sizing." Concrete examples make your agent reply better.
</Tip>

<Note>
  Every change shows up in the draft first. [Test it](/en/your-agent/testing) before publishing to see how it replies with the new setup.
