Install target

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

    Only contacts known or declared hosts: github.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.

    Hosts contacted

    github.comsource host

  • 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 microck/ordinary-claude-skills at 1056d293d4.

    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 expertise in modern JavaScript patterns. It allows the AI agent to understand and apply techniques like modules, asynchronous programming with promises and async/await, and functional programming concepts for cleaner, more maintainable code. The skill helps generate efficient and readable JavaScript solutions based on current best practices.

When to use it

  • Code Generation: Generate JavaScript code snippets or complete functions based on a description of desired functionality.
  • Code Refactoring: Suggest improvements to existing JavaScript code for better readability, performance, or adherence to modern patterns.
  • Debugging Assistance: Help identify and explain issues in JavaScript code by applying knowledge of common pitfalls and best practices.
  • Learning & Explanation: Explain complex JavaScript concepts and demonstrate their practical application with examples.

Key capabilities

  • Modules (ES Modules)
  • Promises and Async/Await
  • Functional Programming principles
  • Modern JavaScript syntax and features

Example prompts

  • "Write a function using async/await to fetch data from this API endpoint: [API Endpoint]"
  • "Refactor this code snippet to use ES modules: [Code Snippet]"
  • “Explain the difference between map and forEach in JavaScript.”

Tips & gotchas

The skill assumes a basic understanding of JavaScript fundamentals. Providing context or specific requirements will improve the quality of generated code or explanations.
