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 wsimmonds/claude-nextjs-skills at 9e0aa5f99b.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill provides foundational knowledge for working with the App Router in Next.js, including routing, layout components, and file-based routing structure. It covers how to organize pages, use dynamic routes, and manage shared UI elements efficiently.

When to use it

  • When setting up a new Next.js project using the App Router instead of the Pages Router.
  • When you need to create nested layouts or shared components across multiple routes.
  • When implementing dynamic routing for features like blog posts or user profiles.

Key capabilities

  • Understanding of file-based routing in the app/ directory structure.
  • Use of layout components to share UI between pages.
  • Implementation of dynamic and optional catch-all routes.

Example prompts

  • "How do I set up a nested route using the App Router in Next.js?"
  • "Can you explain how to create a shared layout component for multiple pages?"
  • "What is the best way to handle dynamic routing with parameters in the App Router?"

Tips & gotchas

  • Ensure your project uses Next.js version 13 or higher, as the App Router is not available in earlier versions.
  • Be mindful of how file structure affects route hierarchy—misplaced files can lead to unexpected behavior.
