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 jeffallan/claude-skills at 1be15d8064.

    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

The react-expert skill provides advanced knowledge of React, including component structure, state management, hooks, and best practices. It enables AI agents to write, debug, and optimize React code effectively.

When to use it

  • You need help building complex UIs with React components
  • You're troubleshooting performance issues in a React application
  • You want to implement advanced features like custom hooks or context APIs

Key capabilities

  • Writing reusable and maintainable React components
  • Managing state with hooks such as useState, useEffect, and useContext
  • Optimizing component rendering and performance
  • Debugging common issues in React applications

Example prompts

  • "How can I optimize this React component for better performance?"
  • "Can you explain how to use the useContext hook for global state management?"
  • "I'm getting a warning about unnecessary re-renders. How do I fix it?"

Tips & gotchas

  • Ensure your project is set up with a modern version of React (18 or newer) for full compatibility.
  • While this skill provides strong guidance, always test changes in your local environment before deployment.
