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 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: vercel.com.

    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 cesarecaoduro/agent-skills at ab6769e204.

    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 vercel-sandbox skill provides a sandboxed environment to run and test code snippets. It allows users to execute JavaScript, TypeScript, or other supported languages within a controlled space. This is useful for experimentation, debugging, and evaluating code without impacting the main system.

When to use it

  • Testing Code Snippets: Quickly evaluate small pieces of code you've written or found online.
  • Debugging: Isolate and debug problematic code in a safe environment.
  • Learning New Languages/Libraries: Experiment with new programming languages or libraries without installing them locally.
  • Prototyping: Rapidly prototype ideas and test concepts before integrating them into larger projects.

Key capabilities

  • Sandboxed execution environment
  • Support for JavaScript and TypeScript (and potentially other languages)
  • Code snippet evaluation
  • Debugging assistance

Example prompts

  • "Run this code: console.log('Hello, world!');"
  • "Execute the following TypeScript function: function add(a: number, b: number) { return a + b; }"
  • "Can you run and show me the output of this JavaScript snippet?"

Tips & gotchas

The skill's capabilities are limited to what can be executed within its sandboxed environment. Complex or resource-intensive tasks might not be suitable for use with vercel-sandbox.
