# Sandbox & Chat

> Ephemeral agent runs and interactive conversations without creating permanent agents.

## Sandbox

The Sandbox is a scratchpad for quick, throwaway agent runs. Nothing is saved to the database. No agent record is created.

Use it to:

* Test a system prompt before assigning it to a real agent
* Try a one-off task without cluttering your agent list
* Experiment with different models or MCP configurations

### How it works

<Columns cols={2}>
  <Card title="Configure" icon="sliders">
    Set the model, system prompt, and whether to enable MCP servers. Everything lives in the left panel.
  </Card>

  <Card title="Converse" icon="messages">
    Type a prompt and get a response. The conversation appears as a chat thread in the right panel.
  </Card>
</Columns>

### Session persistence

The Sandbox supports multi-turn conversations within a session. After the first response, muxAI captures the Claude CLI `session_id` and passes `--resume <sessionId>` on subsequent messages. The agent picks up where it left off with full context.

Click **New Session** to reset and start fresh. Sessions are also cleared on page reload.

<Tip>
  The Sandbox is fully stateless from the database's perspective. No runs, no logs, no results are persisted. When you close the page, it's gone.
</Tip>

## Chat

Chat is similar to the Sandbox but designed for open-ended conversations rather than agent testing. It provides a clean chat interface for interacting with Claude directly.

Both Sandbox and Chat are found in the sidebar under their respective sections.
