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 velcrafting/codex-skills at 0d720417d0.

    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 expertise in Supabase, a popular open-source Firebase alternative. It can assist with database design and optimization, implementing authentication flows using Supabase's Auth system, and building real-time features leveraging PostgreSQL’s capabilities within the Supabase platform. The agent can also help troubleshoot issues related to data storage and retrieval within a Supabase project.

When to use it

  • Database Schema Design: You need assistance designing a relational database schema for your application using Supabase's PostgreSQL backend.
  • Authentication Implementation: You want to implement user authentication, authorization, and role-based access control in your application leveraging Supabase Auth.
  • Real-time Feature Development: You are building features that require real-time updates and data synchronization within a Supabase project.
  • Troubleshooting Database Issues: You're encountering errors or performance bottlenecks with your existing Supabase database and need help diagnosing the problem.

Key capabilities

  • Database design & optimization in PostgreSQL (Supabase)
  • Implementation of authentication flows using Supabase Auth
  • Real-time feature development leveraging PostgreSQL’s capabilities
  • Troubleshooting data storage and retrieval issues within a Supabase project

Example prompts

  • "Can you help me design a database schema for an e-commerce application in Supabase?"
  • "How do I implement email authentication with password reset using Supabase Auth?"
  • "I'm experiencing slow query performance in my Supabase database. Can you suggest some optimization strategies?"

Tips & gotchas

This skill assumes a basic understanding of relational databases and PostgreSQL concepts. While it can assist with complex tasks, providing clear context about your existing Supabase project will yield better results.
