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 hainamchung/agent-assistant at 89cb983bb4.

    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 advanced JavaScript expertise to AI agents. It enables complex code generation, debugging, and optimization for various web development tasks. The agent can leverage this skill to build interactive frontends, manage backend logic, and create efficient Node.js applications.

When to use it

  • Building a Web Application: Generate the necessary Javascript code for a new feature or entire application.
  • Debugging Existing Code: Identify and fix errors in existing JavaScript projects.
  • Optimizing Performance: Analyze and improve the speed and efficiency of JavaScript code.
  • Creating Node.js Servers: Develop backend functionality using Node.js and related frameworks.

Key capabilities

  • Code generation
  • Debugging
  • Optimization
  • Node.js development

Example prompts

  • "Generate a React component for displaying user profiles."
  • "Debug this JavaScript code: [paste code here]"
  • "Optimize this function to improve its performance: [paste code here]"
  • "Create a simple Node.js server that serves static files."

Tips & gotchas

The skill assumes a basic understanding of JavaScript syntax and concepts. Complex requests may require providing clear context or existing codebase snippets for the agent to effectively utilize its capabilities.
