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 failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • Declares what it does: failed

    No SKILL.md was found in the skill's directory.

    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 sickn33/antigravity-awesome-skills at 5a4cdd9df8.

    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 best practices for working with Supabase and PostgreSQL, including schema design, query optimization, security configurations, and performance tuning. It helps developers build efficient and secure database-driven applications using Supabase's Postgres backend.

When to use it

  • You're designing a new database schema for a Supabase project.
  • You need to optimize slow queries in your PostgreSQL database.
  • You want to ensure proper security configurations like row-level security or role-based access control.
  • You are troubleshooting performance issues with your Supabase backend.

Key capabilities

  • Schema design recommendations for Supabase tables and relationships
  • Query optimization techniques for PostgreSQL
  • Security best practices (e.g., RLS, JWT authentication)
  • Performance tuning strategies for high-throughput applications

Example prompts

  • "How do I set up row-level security in Supabase?"
  • "What are the best practices for indexing in PostgreSQL with Supabase?"
  • "Can you explain how to optimize a slow query on a large table in Supabase?"

Tips & gotchas

  • Ensure your Supabase project is properly configured before applying these practices.
  • Indexing strategies should be tailored to your specific workload and query patterns.
