Automated safety checks
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

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 adherence to established standards. The skill can generate SQL queries, suggest schema improvements, and offer advice on managing database resources effectively.
When to use it
- You're designing a new application using Supabase and want to proactively implement best practices.
- Your existing Supabase/PostgreSQL database is experiencing performance issues and you need optimization suggestions.
- You’re unsure about the correct way to structure your database schema for scalability and maintainability.
- You require assistance in implementing security measures like row-level security or data encryption within your Supabase project.
Key capabilities
- SQL query generation based on best practices.
- Schema design recommendations.
- Performance optimization suggestions.
- Security implementation guidance (e.g., Row Level Security).
Example prompts
- "Suggest a better schema for managing user profiles in my Supabase database."
- "Generate an SQL query to efficiently retrieve all active users sorted by registration date."
- "How can I implement row-level security on my 'orders' table?"
- “What are some best practices for indexing large tables in Supabase?”
Tips & gotchas
This skill assumes a basic understanding of PostgreSQL and Supabase concepts. While it offers recommendations, always review and test any changes thoroughly in a non-production environment before applying them to your live database.
