    Example session with this skill installed

    Generate a schema for a blog with users, posts, and comments. Users should only be able to edit their own posts.

    • Read your context and instructions
    • Compiled the supabase schema builder

    CREATE TABLE posts (
    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    author_id UUID REFERENCES auth.users NOT NULL,
    title TEXT NOT NULL,
    content TEXT

    );
ALTER TABLE posts ENABLE ROW LEVEL SECURITY;
CREATE POLICY "Authors can update own posts" ON posts FOR UPDATE USING (auth.uid() = author_id);

    Connects securely to your tools. The creator never sees your data.

    What you get

    Design multi-tenant database tables with strict RLS isolation.Generate Supabase CLI compatible migration files automatically.Create TypeScript interfaces for database tables to ensure type safety.Secure tables by mapping SELECT/UPDATE policies to auth.uid().

    About this skill

    The problem

    Designing secure PostgreSQL schemas for Supabase is error-prone. Manually writing boilerplate for RLS policies, foreign keys, and TypeScript types often leads to security gaps or type mismatches.

    What it does

    • Generates complete SQL schemas with UUID primary keys and automated timestamp triggers.
    • Writes granular Row Level Security (RLS) policies mapped to auth.uid() for every table.
    • Produces sequential migration scripts compatible with the Supabase CLI.
    • Exports strongly typed TypeScript interfaces for the @supabase/supabase-js client.

    Frameworks & tools

    PostgreSQL, Supabase CLI, Node.js, and TypeScript.

    Why this beats prompting it yourself

    Standard LLM prompts often forget to enable RLS by default or miss critical foreign key constraints. This skill enforces a production-ready standard that includes essential triggers and auth-aware security policies without manual reminders.

    Use cases

    • Scaffolding a multi-tenant SaaS database with workspace-level isolation.
    • Adding secure project boards and task management tables to an existing app.
    • Generating valid TypeScript types after a schema change to fix frontend build errors.
    • Creating isolated user profiles that link correctly to Supabase Auth.
