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 xfstudio/skills at 1bf6044db2.

    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 data integrity, security, and optimal performance through adherence to established standards and patterns. The skill focuses on practical advice applicable across various development stages, from initial setup to ongoing maintenance.

When to use it

  • Database Design: Seeking recommendations for table structures, indexing strategies, and relationship modeling within your Supabase project.
  • Security Audits: Needing assistance in identifying potential vulnerabilities and implementing secure coding practices related to database access and data handling.
  • Performance Optimization: Looking for ways to improve query performance, reduce latency, and scale your PostgreSQL database effectively.
  • Migration Planning: Preparing for database migrations or schema changes while minimizing downtime and ensuring data consistency.

Key capabilities

  • Database Schema Design Recommendations
  • Security Best Practices Implementation
  • Query Performance Optimization Techniques
  • PostgreSQL Specific Configuration Guidance

Example prompts

  • "What are the best practices for indexing a large table in Supabase?"
  • "How can I secure my PostgreSQL database against SQL injection attacks within my Supabase project?"
  • "Suggest ways to optimize slow-running queries on my Supabase database."

Tips & gotchas

This skill assumes some familiarity with PostgreSQL and the basics of Supabase. While it provides guidance, users should always test recommendations in a non-production environment before applying them to live data.
