SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @vercel/sandbox, and includes scripts (resource) components.

What problem does it solve?

This Skill provides a secure, isolated environment for running untrusted code, mitigating risks associated with code execution in production.

Core Features & Use Cases

  • Isolated Execution: Run code in a microVM, preventing unauthorized system access and data leaks.
  • Supports AI Agents & Code Generation: Suitable for executing AI-generated or user-submitted code safely.
  • Use Case: Use the Skill to run potentially harmful scripts in a controlled environment, protecting your main system from any unintended consequences.

Quick Start

Run the vercel-sandbox skill to execute a script in an isolated environment.

Frequently Asked Questions about vercel-sandbox

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I safely execute untrusted code without risking my production environment?▼

Running untrusted code in ephemeral Firecracker microVMs isolates execution from your host system. This approach prevents unauthorized system access and data leaks by providing a secure, controlled environment for potentially harmful scripts.

What is the best way to run AI-generated code safely during experimentation?▼

Executing AI-generated code in ephemeral Firecracker microVMs provides a secure sandbox environment. This isolation approach protects your main system from unintended consequences during safe experimentation with AI agent outputs.

How does code isolation with Firecracker microVMs work for secure execution?▼

Code isolation with Firecracker microVMs works by creating ephemeral, lightweight virtual machines for script execution. This mechanism ensures untrusted code runs in a completely separate environment, preventing unauthorized access to the host system.

Do I need the @vercel/sandbox package to create isolated microVMs?▼

Yes, the @vercel/sandbox package is required for microVM creation and management. It provides the necessary functionality to establish the ephemeral Firecracker microVMs required for isolated code execution.

When should I use ephemeral microVMs for code execution instead of containers?▼

Use ephemeral microVMs when executing highly untrusted code where strong isolation is critical. They provide a more secure boundary than standard containers, protecting against unauthorized system access and potential data leaks.
