SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Agent Sandboxes provide a robust, repeatable environment for safely executing user code, testing packages, and hosting frontends without polluting the host system.

Core Features & Use Cases

  • Sandbox lifecycle management: create, connect, extend, pause, and kill sandboxes reliably.
  • File and project operations: read/write files, upload/download binaries, and manage directories.
  • Unified command execution: run arbitrary commands with fine-grained control over environment, working directory, and timeouts.
  • Frontend hosting and browser validation: expose apps via public URLs and verify accessibility from outside the sandbox.
  • Multi-agent coordination: track and isolate sandbox IDs per agent to avoid cross-talk.

Quick Start

Initialize a sandbox with sbx init, then perform tasks using sbx exec, sbx files, and sbx browser to validate end-to-end workflows.

FAQPage Schema
How do I execute user code safely in an isolated sandbox environment?▼

Yes, multi-agent orchestration is supported by tracking and isolating sandbox IDs per agent to prevent cross-talk. This allows multiple agents to operate concurrently within their own dedicated E2B environments without interfering with each other.

How do I manage the sandbox lifecycle from the command line?▼

You can manage the sandbox lifecycle using a unified CLI to create, connect, extend, pause, and kill sandboxes reliably. It includes sandbox ID tracking and clear reporting of sandbox state and access URLs.

Can I host and validate frontend applications from inside a sandbox?▼

Yes, you can expose applications via public URLs and verify their accessibility from outside the sandbox. This frontend hosting and browser validation ensures your hosted apps are reachable and functioning correctly.

Do I need specific dependencies to automate sandbox creation and file operations?▼

Yes, you need the E2B framework, python-dotenv, and click installed to automate sandbox deployment, file reading and writing, and directory management. These dependencies enable the CLI-driven execution and environment setup.
