SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @cloudflare/sandbox, and includes references (resource) components.

What problem does it solve?

This skill solves the challenge of safely executing untrusted code or running complex computational tasks within a secure, isolated environment on Cloudflare Workers.

Core Features & Use Cases

  • Secure Code Execution: Run Python, JavaScript, or TypeScript in isolated containers with strict resource management.
  • AI Code Interpreter: Enable LLMs to execute generated code, perform data analysis, and return rich outputs like charts or tables.
  • Use Case: Build an interactive coding platform or an AI agent that needs to verify its own logic by running scripts in a sandboxed environment before presenting results to the user.

Quick Start

Use the sandbox sdk to initialize a new code context and execute a python script that performs data analysis on the provided dataset.

Frequently Asked Questions about sandbox-sdk

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

FAQPage Schema
How do I execute untrusted code securely within Cloudflare Workers?▼

You can execute untrusted code securely within Cloudflare Workers by using a sandbox SDK that provides an isolated runtime environment with strict resource management via Docker-based containers and Durable Objects.

Can I run Python scripts for data analysis in an isolated Cloudflare environment?▼

Yes, you can run Python scripts for data analysis in an isolated Cloudflare environment by initializing a new code context with the SDK, which manages execution and returns rich outputs like charts or tables.

How do I build an AI code interpreter that runs generated scripts safely?▼

Build an AI code interpreter by integrating a sandbox SDK to execute LLM-generated scripts inside isolated containers, allowing the AI agent to verify its logic and perform computations before presenting results to the user.

Do I need Durable Objects and Docker to manage code execution lifecycle?▼

Yes, you need Durable Objects and Docker-based container images to manage lifecycle and resource isolation when setting up secure, isolated code execution environments within Cloudflare Workers.

What are the limitations of running shell commands in a Cloudflare Workers sandbox?▼

Running shell commands in a Cloudflare Workers sandbox requires strict resource management within isolated Docker containers, meaning execution is constrained by the lifecycle and resource limits enforced by Durable Objects.
