Taken from the source listing. We haven't verified who controls this account.

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 polarsource/polar at 6a4f2f6d60.

    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 a curated set of best practices specifically for building React applications on the Vercel platform. It guides AI agents to adhere to performance, security, and maintainability standards unique to the Next.js ecosystem and Vercel's serverless infrastructure.

When to use it

  • Generating production-ready React components that leverage Vercel-specific optimizations like Image Optimization and Font Optimization.
  • Configuring build pipelines and deployment settings to ensure efficient serverless function execution on Vercel.
  • Implementing secure patterns for handling API routes, authentication, and client-side data fetching within a Next.js project.
  • Structuring codebases to align with Vercel's recommended file organization and dependency management strategies.

Key capabilities

  • Enforces Next.js-specific coding standards and architectural patterns.
  • Optimizes asset delivery and rendering performance for Vercel-hosted applications.
  • Applies security best practices relevant to serverless environments.
  • Ensures compatibility with the latest Vercel CLI and deployment workflows.

Example prompts

  • "Generate a Next.js page component that uses next/image correctly for optimal loading on Vercel."
  • "Create an API route handler following Vercel security best practices for handling user data."
  • "Refactor this React code to align with the recommended file structure and performance guidelines for Vercel deployments."

Tips & gotchas

Ensure your project is initialized with the Next.js framework, as these best practices are tightly coupled with its features. While the skill covers general React principles, prioritize its specific guidance when deploying to Vercel to maximize platform benefits like Edge Functions and automatic caching.
