# Agent Chat

**Agent Chat** is where you build your app. You write your prompts in the **composer** at the bottom, the agent responds and works in the same view, and a feed shows each step as it goes. From the composer you can add context, attach images, and line up follow-up messages while the agent works.

## The Composer

Type your prompt in the composer and send it, or click the send button (the up arrow) to its right. While the agent is running, that same button becomes a stop button. See [Iterating](/prompting/iterating).

> [!TIP]
> Prefer a different key to send? You can change how the keyboard sends and steers your messages in **Settings**, under **Send Message** in the **General** tab.

### Recalling Past Prompts

With the composer empty, press `↑` to bring back your previous prompt, and `↑` again to step further back through what you've sent. Press `↓` to move forward again. This is handy for resending a prompt with a small tweak.

## Add Context Menu

The **Plus** button to the left of the composer opens a menu where you add context to your next prompt. This menu contains:

- **Plan**: Turn on Plan mode so the agent agrees on an approach with you before writing code. See [Plan & Build Modes](/prompting/plan-and-build-modes).
- **Attachment**: Pick an image from your computer to attach as a reference.
- **Integration**: Connect your app to an outside service. Choose **GitHub**, **Linear**, **Slack**, or **Other OAuth Provider** from the menu, and the agent sets up the connection as it builds your app. See [Integrations Overview](/integrations/overview).

## Annotating Your App

The composer has an ** Annotate** button for pointing at parts of your app you'd like to tweak or change, so the agent knows exactly what you mean instead of describing it. See [Annotate](/prompting/annotate).

## Attaching Images

Images are the fastest way to show the agent what you mean, whether it's a screenshot of something to fix, a design to match, or a mockup to work from. There are three ways to attach an image:

- **Paste it**: Copy an image and paste it straight into the composer.
- **Pick a file**: Open the Plus menu and choose **Attachment**, then select an image from your computer.
- **Drag it in**: Drag an image from Finder onto the chat.

Attached images appear as thumbnails above the composer. Click one to preview it, or remove it before sending. Combine an image with words for the clearest direction, such as a screenshot plus "make this button match the others."

> [!NOTE]
> For pointing at part of your **running** app rather than attaching a separate image, use the annotation tool. See [Annotate](/prompting/annotate).

## Queuing Follow-Ups

You don't have to wait for the agent to finish before lining up your next message. While the agent is running, type a follow-up and send it, and it joins a queue that runs after the current turn.

Queued messages collect just above the composer under a **Queued** count. Hover one to **Send now** (move it ahead and run it next) or **Remove from queue**. This lets you think a few steps ahead while the agent works through the current step.

> [!TIP]
> Want your message to redirect the agent right away rather than wait in line? That's **steering**, and you can switch the behavior of the send key while the agent is busy. See [Iterating](/prompting/iterating).

## Your Draft Is Kept As You Work

Your in-progress message stays put as you move around the chat, so a half-written prompt isn't lost if you glance at the feed or switch views. To clear a draft you've decided against, select the text and delete it.
