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

    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 vercel/vercel-plugin at c632a50838.

    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 expert guidance on best practices for building React applications using Vercel. It includes recommendations for performance optimization, code structure, deployment strategies, and integration with modern tools like Next.js.

When to use it

  • You're optimizing a React app's performance before deploying to production
  • Setting up a new React project with Vercel and want to follow industry standards
  • Improving the maintainability and scalability of an existing React application
  • Preparing documentation for developers joining a React-based project

Key capabilities

  • Code splitting and lazy loading strategies
  • Performance optimization techniques (e.g., image optimization, caching)
  • Best practices for using Next.js with Vercel
  • Security recommendations for client-side and server-side rendering
  • Deployment configuration tips for production environments

Example prompts

  • "How can I optimize my React app's load time when deploying on Vercel?"
  • "What are the best practices for structuring a large-scale React application with Next.js?"
  • "Can you explain how to implement lazy loading in a React project hosted on Vercel?"

Tips & gotchas

  • Ensure your project is set up with Next.js if using advanced deployment features.
  • Some optimizations may require additional configuration in next.config.js or vercel.json.
