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 guanyang/antigravity-skills at 0d6f1e7d3f.

    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 users optimize database performance, ensure data security, and maintain code quality through practical advice and examples. The skill focuses on common pitfalls and offers solutions for efficient development workflows within the Supabase ecosystem.

When to use it

  • You're designing a new application using Supabase and want to build a solid foundation from the start.
  • Your existing Supabase database is experiencing performance issues or scalability concerns.
  • You need help understanding and implementing security best practices for your data in Supabase.
  • You are looking for guidance on structuring your PostgreSQL schema within a Supabase project.

Key capabilities

  • Database optimization techniques
  • Security recommendations
  • Schema design patterns
  • Performance tuning strategies
  • Best practice examples

Example prompts

  • "What are some best practices for indexing my tables in Supabase?"
  • "How can I secure my database against SQL injection attacks within a Supabase project?"
  • "Suggest a good schema structure for storing user data in a Supabase application."

Tips & gotchas

This skill assumes basic familiarity with PostgreSQL and Supabase concepts. While it offers practical advice, always test changes thoroughly in a development environment before applying them to production.
