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 passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • 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 undeclared network calls: passed

    Makes no network calls.

    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.

  • 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 vangongwanxiaowan/screen-creative-skills at 6ced54f40c.

    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 script-evaluator skill allows an AI agent to execute and interpret the results of short scripts written in JavaScript. It can be used for simple calculations, data manipulation, or running basic logic within a larger workflow. The output of these scripts is then returned as text, enabling further processing by other skills.

When to use it

  • Simple Calculations: Quickly perform mathematical operations without needing external tools.
  • Data Transformation: Manipulate small datasets using JavaScript functions (e.g., filtering lists).
  • Conditional Logic: Implement simple "if/then" logic based on script output.
  • Code Snippet Testing: Evaluate short code snippets to verify functionality before integration into a larger project.

Key capabilities

  • JavaScript execution
  • Text-based output of script results
  • Support for basic JavaScript syntax and functions

Example prompts

  • "Calculate 2 + 2 and return the result."
  • "Evaluate [1, 2, 3].filter(x => x > 1) and give me the filtered array."
  • "Run this script: let a = 5; let b = 10; console.log(a * b);"

Tips & gotchas

The skill is limited to relatively short scripts due to resource constraints. Complex or long-running JavaScript code may not execute correctly.
