SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Build sandboxed applications for secure code execution. Load when building AI code execution, code interpreters, CI/CD systems, interactive dev environments, or executing untrusted code. Covers Sandbox SDK lifecycle, commands, files, code interpreter, and preview URLs.

Core Features & Use Cases

  • Sandbox lifecycle: Get, configure, and destroy isolated environments on demand.
  • Code execution & interpretation: Run shell commands, execute code snippets, and manage code contexts for persistent state.
  • Open integration points: Supports integration with Agents SDK, AI tooling, and development workflows for secure testing and prototyping.

Quick Start

Install the SDK and initialize a sandbox, then run a sample script to verify setup.

Frequently Asked Questions about sandbox-sdk

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

FAQPage Schema
How do I run untrusted code securely in an AI workflow?▼

Sandboxed code execution isolates untrusted scripts within disposable environments, preventing host system compromise. It is essential for running AI-generated code, building code interpreters, and testing CI/CD pipelines securely.

How do I execute code and maintain state in a sandboxed environment?▼

You can execute code snippets and manage code contexts within the sandbox to maintain persistent state across multiple runs. The API supports shell commands, file I/O, and code interpretation for interactive workflows.

Can I use sandboxed code execution with CI/CD pipelines and Agents SDK?▼

Yes, the sandbox supports integration with AI tooling, the Agents SDK, and CI/CD pipelines. It provides isolated runtimes for secure testing, prototyping, and automated development workflows.

How do I manage the lifecycle of an isolated code execution environment?▼

You can automate the full sandbox lifecycle by using the API to get, configure, and destroy isolated environments on demand. This ensures disposable runtimes are cleanly removed after code execution completes.

Does the sandbox support exposing ports and previewing applications?▼

Yes, the sandbox supports port exposure and provides preview URLs. This allows you to expose running applications within the isolated environment for interactive development and testing.
