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 failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: oauth2.googleapis.com.

    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.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

    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.

About this skill

The Next.js authentication skill streamlines user identity management within Next.js applications by integrating secure login flows. It provides pre-configured boilerplates for common providers like Auth0, Clerk, and NextAuth.js to reduce development time.

When to use it

  • Rapidly prototype user registration and login pages without building custom backend logic.
  • Integrate third-party identity providers (e.g., Google, GitHub) into your frontend application.
  • Implement session management and protected routes for dashboard or SaaS features.
  • Standardize security practices across multiple projects using established authentication libraries.

Key capabilities

  • Pre-built configurations for major authentication providers including Auth0, Clerk, and NextAuth.js.
  • Ready-to-use components for sign-up, sign-in, and password reset flows.
  • Automatic handling of session tokens and user state persistence.
  • Support for both client-side rendering (CSR) and server-side rendering (SSR) patterns.

Example prompts

  • "Set up a secure login page using NextAuth.js with Google OAuth integration."
  • "Generate the necessary boilerplate code to implement Clerk authentication in my Next.js project."
  • "Create protected routes that redirect unauthenticated users to a sign-in page using Auth0."

Tips & gotchas

Ensure your environment has the required API keys or client secrets from your chosen identity provider before running the generated code. Always review the default security settings, as some boilerplates may include debug flags that should be disabled in production.
