## Open AI FDE

Select **AI FDE** from the dashboard sidebar.

You can also open the AI FDE mascot while editing an agent. In the Agent Builder, AI FDE already knows which agent and version are open.

## Start your first request

<Steps>
  <Step title="Choose a mode">
    Select **Ask**, **Auto**, or **Plan** depending on whether you want advice, direct action, or approval before building.
  </Step>

  <Step title="Describe the result">
    Type your request in **Help me build an agent…**. Include the purpose, language, audience, and important actions.
  </Step>

  <Step title="Add supporting files">
    If needed, attach a document, spreadsheet, screenshot, recording, or other reference file.
  </Step>

  <Step title="Send the request">
    Select **Send** and follow any questions or approval steps shown in the conversation.
  </Step>
</Steps>

## Example requests

<AccordionGroup>
  <Accordion title="Create a customer support agent" icon="headset">
    ```text theme={null}

    and transfer difficult cases to a human.
    ```
  </Accordion>

  <Accordion title="Create an appointment-booking agent" icon="calendar-check">

    ```
  </Accordion>

  <Accordion title="Improve an existing agent" icon="pen-to-square">
    ```text theme={null}
    Review the opening of this version. Make it shorter and more natural,
    but keep the same purpose and language.
    ```
  </Accordion>

  <Accordion title="Analyze a failed call" icon="phone-xmark">
    ```text theme={null}
    Review this call and explain why the transfer failed.
    Tell me what happened and what I should check next.
    ```
  </Accordion>
</AccordionGroup>

## What happens after a build

A successful build is saved as a **new agent version**. Existing versions are not overwritten.

<Warning>
  Saving and publishing are different actions. Review and test the new version before asking AI FDE to publish it or making it live.
</Warning>

## Get better results

Use clear requests that include:

* What the agent should achieve.
* Who it will call or support.
* The language it should speak.
* Information it should collect.
* Actions it should perform.
* Rules it must follow.

<Tip>
  You do not need to write a technical prompt. Explain the business goal as if you were briefing a new team member.
