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 nembie/claude-code-skills at 874ba31248.

    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 generates Next.js middleware files based on provided instructions or specifications. It automates the creation of common middleware patterns, reducing boilerplate and speeding up development. The generated middleware can handle tasks like authentication, redirection, and A/B testing.

When to use it

  • You need to implement authentication checks for specific routes in your Next.js application.
  • You want to redirect users based on their location or other criteria.
  • You're setting up A/B testing and require middleware to route traffic between different versions of a page.
  • You are starting a new Next.js project and need to quickly establish common middleware patterns.

Key capabilities

  • Generates complete Next.js middleware files.
  • Supports authentication logic within the middleware.
  • Handles redirection based on specified conditions.
  • Enables A/B testing routing via middleware.

Example prompts

  • "Create a Next.js middleware file that redirects all unauthenticated users to the login page."
  • "Generate a middleware for A/B testing, splitting traffic 50/50 between /page-a and /page-b."
  • "Write a middleware that checks for a specific cookie and redirects if it's missing."

Tips & gotchas

  • Requires familiarity with Next.js concepts like routing and middleware.
  • The generated code may need adjustments based on your project’s specific needs and dependencies.
