Sandbox Service

Listed
lin-a1·vlatest·security

This skill creates isolated environments (sandboxes) for testing applications and services safely without impacting live systems, streamlining development workflows.

Repository

Install on your platform

Showing Claude Code. One command installs this skill into any of the agents below.

  1. 1

    Run this in your project

    terminal
    $ npx skills add lin-a1/skills-agent --skill sandbox-service -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 2 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: download.docker.com, pypi.tuna.tsinghua.edu.cn.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned lin-a1/skills-agent at 22b3795060.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The sandbox-service skill provides a safe and isolated environment to execute code or commands. It allows users to test potentially risky operations without impacting the main system, ensuring stability and preventing unintended consequences. This is achieved by running tasks within a contained space with limited access to resources.

When to use it

  • Testing experimental code: Run new scripts or functions in isolation before integrating them into your primary workflow.
  • Executing untrusted commands: Safely process instructions from external sources without compromising system security.
  • Debugging complex issues: Isolate and reproduce problems within a controlled environment to facilitate troubleshooting.
  • Evaluating third-party tools: Assess the functionality and safety of new software or libraries before full adoption.

Key capabilities

  • Isolated execution environment
  • Limited resource access
  • Safe code testing
  • Command isolation

Example prompts

  • "Run this Python script in a sandbox: [script content]"
  • "Execute the command 'rm -rf /' within a sandboxed environment."
  • "Test this Docker image and report any errors without affecting my system."

Tips & gotchas

The skill requires appropriate permissions to create and manage isolated environments. Be mindful of resource limits imposed on the sandbox to prevent excessive consumption.
