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 davila7/claude-code-templates at 79182c51fb.

    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

nextjs-supabase-auth

What it does

This skill provides a pre-configured authentication system for Next.js applications using Supabase. It handles user registration, login, and session management with minimal setup code.

When to use it

  • Rapidly prototype secure user accounts without writing boilerplate auth logic.
  • Integrate backend database access into frontend React or Next.js projects.
  • Deploy full-stack apps that require persistent user sessions quickly.
  • Reduce development time when building MVPs needing immediate login functionality.

Key capabilities

  • Pre-built Next.js integration with Supabase client libraries.
  • Automatic handling of OAuth providers (Google, GitHub, etc.).
  • Secure session management and token refresh logic.
  • Ready-to-use UI components for sign-up and sign-in flows.
  • Environment variable configuration for API keys and URLs.

Example prompts

  • "Create a Next.js app with Supabase authentication using the davila7 template."
  • "Add Google login to my existing Next.js project via Supabase auth."
  • "Generate a secure user registration form connected to Supabase."

Tips & gotchas

Ensure your .env.local file contains valid NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY values before running the app. This skill relies on the Next.js App Router structure; legacy Page Router projects may require manual adjustments.
