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 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 guidance for building advanced Next.js applications using the App Router. It covers features like Route Handlers (API routes), Parallel Routes, Intercepting Routes, Server Actions, error handling, draft mode, and streaming with Suspense. A key focus is on adhering to strict TypeScript coding standards within the provided codebase.

When to use it

  • Creating API endpoints using Route Handlers.
  • Implementing parallel or intercepting routes for complex navigation patterns (e.g., modals, drawers).
  • Building forms and handling data mutations with Server Actions.
  • Setting cookies or managing application state.
  • Developing CMS previews utilizing draft mode.

Key capabilities

  • Guidance on Route Handlers (API Routes)
  • Support for Parallel and Intercepting Routes
  • Implementation of Server Actions
  • Error handling strategies
  • Draft Mode integration
  • Streaming with Suspense
  • TypeScript type pattern examples (Page props, form events, server actions)

Example prompts

  • "How do I create an API endpoint in Next.js using a Route Handler?"
  • "Can you show me how to implement parallel routes for a modal window?"
  • "What's the correct way to handle form submissions with Server Actions and TypeScript?"

Tips & gotchas

  • TypeScript is critical: The codebase enforces strict TypeScript rules; avoid using the any type, as it will cause build failures. Use specific types like React.FormEvent<HTMLFormElement> instead.
  • Server Action Filenames: Pay close attention to required filenames when implementing Server Actions. If no name is specified, default to app/actions.ts for multiple actions or app/action.ts for a single handler.
