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 poletron/custom-rules at aba6668777.

    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 authentication functionality for Next.js applications using Supabase. It streamlines user sign-up, login, and session management within a Next.js environment, leveraging the features of Supabase's authentication services. The skill simplifies integration with existing Next.js projects, reducing boilerplate code typically required for implementing secure user authentication.

When to use it

  • Building a new Next.js application that requires user accounts and login functionality.
  • Adding authentication to an existing Next.js project without wanting to manually configure Supabase auth.
  • Rapid prototyping of applications where user authentication is a core feature.
  • Creating internal dashboards or admin panels requiring secure access control.

Key capabilities

  • Next.js integration
  • Supabase Authentication
  • User sign-up functionality
  • Login functionality
  • Session management

Example prompts

  • "Implement user authentication in my Next.js app using Supabase."
  • “Add a login form to my existing Next.js project, integrated with Supabase.”
  • "Create a secure admin panel for my application using Next.js and Supabase authentication."

Tips & gotchas

  • Requires a working Next.js development environment.
  • A Supabase account is necessary to utilize the skill's functionality.
