📄 Description

Summary

  • Add @langchain/deno-sandbox package - a new Deno Sandbox backend for DeepAgents that enables agents to execute commands in isolated Linux microVMs using Deno Deploy's Sandbox infrastructure
  • Add example demonstrating DeepAgent with Deno Sandbox at examples/sandbox/deno-sandbox.ts
  • Simple authentication using DENO_DEPLOY_TOKEN environment variable

Features

The new @langchain/deno-sandbox package provides:

  • DenoSandbox class - Extends BaseSandbox to provide command execution, file operations, and sandbox lifecycle management
  • Factory methods - DenoSandbox.create() for new sandboxes and DenoSandbox.connect() to reconnect to existing ones
  • Full SDK access - Access the underlying Deno SDK via sandbox.sandbox property for advanced features (SSH, HTTP port exposure, JS eval, etc.)
  • Configurable resources - Set memory (768MB-4GB), lifetime (session or duration), and region

Usage

import { createDeepAgent } from "deepagents";
import { DenoSandbox } from "@langchain/deno";

const sandbox = await DenoSandbox.create({
  memoryMb: 1024,
  lifetime: "session",
});

try {
  const agent = createDeepAgent({
    model: new ChatAnthropic({ model: "claude-haiku-4-5" }),
    systemPrompt: "You are a coding assistant with sandbox access.",
    backend: sandbox,
  });

  await agent.invoke({ messages: [...] });
} finally {
  await sandbox.close();
}

Authentication

Set the DENO_DEPLOY_TOKEN environment variable:

  1. Go to https://app.deno.com → Settings → Organization Tokens
  2. Create a new token
  3. export DENO_DEPLOY_TOKEN=your_token_here
