SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires e2b, python-dotenv, click.

What problem does it solve?

The Agent Sandboxes skill enables teams to manage and automate working within isolated E2B sandboxes, reducing risk when executing untrusted code, testing packages, cloning repositories, and hosting sandboxed frontends.

Core Features & Use Cases

  • Isolated Execution: Run code and commands inside gated sandboxes to protect the host system.
  • Multi-Agent Coordination: Support for parallel sandboxes and independent sandbox IDs per agent to prevent cross-interference.
  • Unified CLI Orchestration: A cohesive workflow that covers init, plan, build, host, and test steps for end-to-end sandbox tasks.

Quick Start

  1. Activate the skill and initialize a sandbox with a template: use uv run sbx init --template fullstack-vue-fastapi-node22 --timeout 1800 and capture the sandbox_id.
  2. Use sbx commands to install tools, build projects, and expose a public URL via sbx sandbox get-host <sandbox_id> --port 5173.
  3. Run browser/UI tests using the browser commands and the provided plan for browser UI testing.

FAQPage Schema
How do I safely execute untrusted code in isolated sandboxes using E2B?

You can safely execute untrusted code in E2B sandboxes by using a unified CLI workflow that runs initialization, planning, building, hosting, and testing steps inside gated environments to protect the host system.

How does multi-agent coordination work for parallel sandbox orchestration?

Multi-agent coordination works by supporting parallel sandboxes and assigning independent sandbox IDs per agent, which prevents cross-interference when multiple AI agents execute tasks concurrently.

Can I host a sandboxed frontend and expose a public URL with this CLI orchestration tool?

Yes, you can host a sandboxed frontend and expose a public URL by running the sandbox get-host command with your specific sandbox ID and designated port number to grant public access.

What is the best way to run browser UI tests inside an isolated execution environment?

The best way to run browser UI tests inside an isolated execution environment is to use the provided browser commands alongside the testing plan within the E2B sandbox workflow.

Do I need Docker to run isolated code execution workflows with E2B?

You do not need Docker to run isolated code execution workflows with E2B because the skill uses the e2b Python package and CLI orchestration to manage secure cloud-based sandbox environments directly.

What are the limitations of using E2B sandboxes for automated testing and hosting?

A key limitation of using E2B sandboxes is that each sandbox requires a specified timeout duration during initialization, meaning long-running automated testing and hosting processes will terminate when the timeout expires.
