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 reactjs/react.dev at 75ef18a917.

    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

The react-expert skill enables AI agents to generate, debug, and optimize React code with deep architectural understanding. It handles complex component lifecycles, state management strategies, and performance tuning specific to the React ecosystem.

When to use it

  • Generating production-ready React components from high-level design descriptions.
  • Debugging intricate state synchronization issues in large-scale applications.
  • Refactoring legacy class-based components into modern functional hooks patterns.
  • Optimizing render cycles and bundle sizes for better user experience.

Key capabilities

  • Advanced component composition and prop drilling reduction
  • Custom hook creation for reusable business logic
  • Context API and Redux integration patterns
  • Server Components and Next.js framework specifics
  • Performance profiling and memory leak detection
  • TypeScript type safety enforcement within React codebases

Example prompts

  • "Create a responsive data table component using React hooks with infinite scroll support."
  • "Refactor this class-based component to use functional components and the useReducer pattern."
  • "Identify potential performance bottlenecks in this React application and suggest optimizations."

Tips & gotchas

Ensure your project uses a compatible version of React and ReactDOM before relying on specific lifecycle methods or hooks. For best results, provide context about existing state management solutions (e.g., Redux, Zustand) when requesting architectural changes.
