# Chat with the agent

> How Mythex chat works — Build, Plan, and Ask modes, streaming progress, and tips for better results.

# Chat with the agent

The left chat panel is how you steer the coding agent.

## What the agent can do

Inside your project sandbox, the agent can:

* Create and edit files
* Install packages
* Run commands in the terminal
* Inspect errors and iterate
* Use project tools exposed by the platform (for example publish helpers, when available in-product)

## Build, Plan, and Ask

In the workspace composer, choose a mode:

| Mode      | Intent                                    |
| --------- | ----------------------------------------- |
| **Build** | Make changes directly in the project      |
| **Plan**  | Discuss approach before editing           |
| **Ask**   | Answer questions **without** editing code |

Use **Plan** when the change is ambiguous or risky. Use **Ask** for explanations, reviews, or “what does this do?” without mutating files. Use **Build** when you want execution.

<Note>
  The dashboard create prompt focuses on starting a project (Build-oriented). Full Build / Plan / Ask modes are available in the project workspace.

## Streaming progress

Agent runs stream live events (text, tool calls). Leave the tab open during a run so you can steer with follow-ups after it finishes.

## Attachments

Where the UI allows, attach screenshots or references so the agent can match layout and copy more closely.

## Sessions and memory

Runs can resume context via the project’s session/checkpointer behavior — the agent is oriented around **this project**, not a generic chat with no files.

## When the agent pauses

If you are **out of tokens**, the agent stops until you top up or your next monthly allotment refreshes (Free or Pro). Files and published apps remain.

If email is **unverified**, the agent will not run until you complete [email verification](/account/email-verification).

See [Tokens](/billing/tokens).
