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 sebas-aikon-intelligence/antigravity-awesome-skills at 0f4a1b2fd7.

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

About this skill

What it does

This skill provides advanced JavaScript expertise to AI agents. It enables the agent to write, debug, and optimize complex JavaScript code, including handling asynchronous operations and working with modern frameworks. The skill aims to significantly improve an agent's ability to develop and maintain robust backend systems using JavaScript.

When to use it

  • Backend Development: Automate tasks like creating APIs, server-side logic, and database interactions in Node.js applications.
  • Code Debugging & Refactoring: Have the AI agent identify and fix bugs or improve existing JavaScript codebases.
  • JavaScript Frameworks: Utilize expertise with modern frameworks to build complex web applications efficiently.
  • Scripting Complex Tasks: Automate repetitive tasks involving JavaScript, such as data processing or system administration scripts.

Key capabilities

  • Advanced JavaScript syntax and semantics understanding
  • Asynchronous programming (Promises, async/await)
  • Debugging and error handling
  • Modern JavaScript framework proficiency
  • Code optimization techniques

Example prompts

  • "Write a Node.js script to fetch data from this API endpoint and save it to a file."
  • "Refactor this JavaScript function to improve its performance and readability."
  • "Debug this code snippet; I'm getting an unexpected error when handling asynchronous requests."

Tips & gotchas

The skill assumes a basic understanding of JavaScript fundamentals. While the agent can generate complex code, reviewing and testing the output is always recommended.
