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 jarmen423/skills at d016f7d2c7.

    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 code snippets 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 project. The skill focuses on practical advice applicable to common development scenarios.

When to use it

  • You're starting a new Supabase project and want to establish good database habits from the beginning.
  • Your existing Supabase application is experiencing slow queries or data integrity issues.
  • You need assistance with implementing security best practices, such as row-level security (RLS).
  • You are unsure about how to structure your database schema for optimal performance and scalability.

Key capabilities

  • Database Schema Design Recommendations
  • Row Level Security (RLS) Implementation Guidance
  • Query Optimization Techniques
  • Data Type Selection Best Practices
  • Secure Data Handling Procedures

Example prompts

  • "How can I implement row-level security in my Supabase table?"
  • "What are some best practices for indexing a PostgreSQL database within Supabase?"
  • "Suggest an efficient schema design for storing user data and their associated posts in Supabase."

Tips & gotchas

This skill assumes you have a basic understanding of SQL and the Supabase platform. The advice provided is general; specific implementations may require adjustments based on your application's unique requirements.
