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 kunhai-88/skills at 2742b5f777.

    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 guidance and recommendations for implementing best practices when working with Supabase and PostgreSQL databases. It helps ensure efficient database design, secure data handling, and optimized query performance within a Supabase environment. The skill focuses on practical advice applicable to both new projects and existing applications.

When to use it

  • You're starting a new project using Supabase and want to establish strong database foundations from the beginning.
  • You’re experiencing slow query times in your Supabase application and need optimization suggestions.
  • You are concerned about data security within your Supabase environment and require guidance on best practices.
  • You're refactoring an existing Supabase project and want to improve its overall database architecture.

Key capabilities

  • Database schema design recommendations
  • Query optimization techniques for PostgreSQL
  • Security best practices for Supabase
  • Guidance on efficient data handling within a Supabase environment

Example prompts

  • "Suggest the optimal way to structure my tables in Supabase for an e-commerce application."
  • "How can I optimize this SQL query running in my Supabase database?"
  • "What are some common security vulnerabilities in Supabase and how can I prevent them?"

Tips & gotchas

This skill assumes a basic understanding of PostgreSQL and Supabase concepts. While it provides best practice recommendations, always test changes thoroughly in a development environment before applying them to production.
