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 marius-townhouse/effective-typescript-skills at d754db2077.

    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 allows an AI agent to generate code in modern JavaScript, adhering to current best practices and utilizing recent language features. It can produce functional components using React, write asynchronous operations with async/await, and leverage ES6+ syntax for cleaner and more efficient code. The agent will focus on producing readable and maintainable JavaScript.

When to use it

  • Generating UI Components: Quickly create reusable React components based on a description or design specifications.
  • Implementing API Interactions: Write asynchronous functions to fetch data from APIs and handle responses effectively.
  • Code Snippet Generation: Produce small code snippets for specific tasks, such as data transformation or validation.
  • Modernizing Legacy Code: Refactor older JavaScript code to utilize modern syntax and patterns.

Key capabilities

  • React functional components
  • async/await for asynchronous operations
  • ES6+ syntax (arrow functions, template literals, destructuring)

Example prompts

  • "Write a React component that displays a list of items fetched from this API endpoint: [API URL]"
  • "Generate an async function to fetch user data and handle potential errors."
  • “Create a JavaScript snippet to format a date string in YYYY-MM-DD format.”

Tips & gotchas

The skill's output is dependent on the clarity of the prompt. Providing specific details about desired functionality and API endpoints will yield more accurate results.
