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 jst-well-dan/skill-box at 935be9cae6.

    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 best practices for working with Supabase and PostgreSQL databases. It helps users optimize database performance, security, and overall architecture when utilizing these technologies. The skill focuses on practical advice applicable to a range of development scenarios involving data storage and management within the Supabase ecosystem.

When to use it

  • You're designing a new application using Supabase and want to ensure optimal database design from the start.
  • Your existing Supabase/PostgreSQL application is experiencing performance issues or security vulnerabilities.
  • You need help understanding how to best leverage specific features of Supabase in conjunction with PostgreSQL.
  • You are troubleshooting errors related to data migrations, schema changes, or query optimization within your Supabase project.

Key capabilities

  • Provides database design recommendations.
  • Offers guidance on performance optimization techniques.
  • Suggests security best practices for protecting sensitive data.
  • Advises on architectural patterns for scalable applications.

Example prompts

  • "What are the best practices for designing a PostgreSQL table in Supabase to store user profiles?"
  • "How can I optimize query performance in my Supabase application?"
  • "Suggest security measures I should implement when using Supabase and PostgreSQL."

Tips & gotchas

This skill assumes some familiarity with both Supabase and PostgreSQL concepts. While it provides guidance, implementing the suggested best practices requires a solid understanding of database administration principles.
