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 kinfe123/fm-skills at a432a4fbfd.

    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

This skill provides a universal JavaScript runtime environment within an AI agent. It allows the agent to execute JavaScript code, enabling tasks like data manipulation, calculations, and interacting with APIs that expose JavaScript functionality. The runtime supports standard JavaScript features and libraries for broader applicability across various backend operations.

When to use it

  • Data Transformation: When you need to perform complex transformations or cleaning of data received from external sources before further processing.
  • API Interaction: To interact with APIs that require JavaScript-specific logic or libraries.
  • Calculations & Logic: For executing calculations, implementing custom algorithms, or performing other logical operations best suited for a JavaScript environment.
  • Code Execution: When you need to dynamically execute small snippets of JavaScript code based on user input or changing conditions.

Key capabilities

  • JavaScript execution engine
  • Support for standard JavaScript libraries
  • Data manipulation within the runtime environment
  • API interaction using JavaScript

Example prompts

  • "Calculate the factorial of 10 using JavaScript."
  • "Transform this JSON data into a CSV format: [JSON Data]"
  • "Execute this JavaScript code: console.log('Hello from JS!')"

Tips & gotchas

The skill requires a basic understanding of JavaScript syntax and concepts to effectively utilize its capabilities. While versatile, complex or resource-intensive JavaScript operations might impact agent performance.
