SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Running untrusted user code or AI-generated code creates security risks. This Skill provides a secure, isolated execution environment using Deno sandboxes to prevent cross-tenant or host-system interference.

Core Features & Use Cases

  • Isolated execution: Each sandbox runs in its own Linux microVM (Firecracker) with a separate filesystem, network, and process space to prevent data leakage.
  • Safe run of untrusted code: Ideal for code playgrounds, AI agent tool execution, and multi-tenant applications requiring strict isolation.
  • Managed lifecycle: Encourages automatic disposal and controlled resource usage to avoid leaks and runaway processes.

Quick Start

Run a sample untrusted code snippet inside a Deno sandbox with automatic disposal.

FAQPage Schema
How do I securely execute untrusted AI agent code in an isolated environment?

Secure execution of untrusted AI agent code is achieved by running it inside a Deno sandbox with isolated filesystem, network, and process space. This prevents cross-tenant interference and host-system data leakage.

What is the best way to isolate untrusted code in a multi-tenant application?

The best way to isolate untrusted code in multi-tenant applications is using a Deno sandbox with a separate Linux microVM. It enforces restricted permissions and per-sandbox isolation to minimize security risks.

How does Deno sandbox isolation prevent host-system interference?

Deno sandbox isolation prevents host-system interference by running each untrusted code execution in its own Linux microVM with a separate filesystem and network space. Restricted permissions further minimize risk.

Can I run a code playground with automatic disposal and restricted permissions?

Yes, you can run a code playground with automatic disposal and restricted permissions using the Deno sandbox. It encourages managed lifecycle control via the await using pattern to avoid resource leaks and runaway processes.

What are the limitations of using a Deno sandbox for secure code execution?

Limitations of using a Deno sandbox include the overhead of running a separate Linux microVM for each execution and the strict managed lifecycle required. You must enforce automatic disposal to prevent resource exhaustion.

Does the Deno sandbox support network and filesystem isolation for AI agent tools?

Yes, the Deno sandbox supports per-sandbox filesystem and network isolation for AI agent tools. This ensures untrusted code execution remains strictly isolated and cannot leak data across tenants.
