• Creates a sandbox based on Bun 1.3
• Installs git and clones this repository
• Installs dependencies
• Configures the server to start automatically on port 3000

The build may take a few minutes. Once complete, your template is ready to use.

3. Use the Client Library

Install the client library in your project:

npm install @dzhng/claude-agent
# or
bun add @dzhng/claude-agent

Connect to your E2B sandbox:

import { ClaudeAgentClient } from '@dzhng/claude-agent'

const client = new ClaudeAgentClient({
  e2bApiKey: process.env.E2B_API_KEY,
  anthropicApiKey: process.env.ANTHROPIC_API_KEY,
  template: 'claude-agent-server', // Your E2B template name
  debug: true,
})

// Start the client (creates E2B sandbox and connects)
await client.start()

// Listen for messages from Claude
client.onMessage(message => {
  if (message.type === 'sdk_message') {
    console.log('Claude:', message.data)
  }
})

// Send a message to Claude
client.send({
  type: 'user_message',
  data: {
    type: 'user',
    session_id: 'my-session',
    message: {
      role: 'user',
      content: 'Hello, Claude!',
    },
  },
})

// Clean up when done
await client.stop()

That's it! The client library handles:

• Creating and managing E2B sandboxes
• WebSocket connection
• Message serialization
• Cleanup and resource management

Modifying the Server

If you want to customize the server behavior:

1. Edit Server Code

The server code is in packages/server/:

• index.ts - Main server and WebSocket handling
• message-handler.ts - Message processing logic
• `...
