    Example session with this skill installed

    Design a Postgres schema for an e-commerce catalog with products including slugs and categories. Ensure categories are linked and soft deletes are enabled.

    • Read your context and instructions
    • Compiled the db-schema
    • Generated the UI component

    -- schema.sql generated for Postgres
    CREATE TABLE products (
    id BIGSERIAL PRIMARY KEY,
    slug VARCHAR(255) UNIQUE NOT NULL,
    price NUMERIC(10,2) NOT NULL,
    category_id BIGINT REFERENCES categories(id),
    deleted_at TIMESTAMP WITH TIME ZONE

    );

    About this skill

    What it does

    This skill transforms natural language requests into production-ready database architectures. It interprets high-level business requirements and automatically generates both the SQL DDL and comprehensive markdown documentation for your data layer.

    Problem it solves

    Designing a normalized database from scratch is time-consuming and prone to manual errors, such as missing indexes on foreign keys, inconsistent naming conventions, or improper data types for currency. This skill automates the drudgery of schema design while enforcing industry best practices from the start.

    Supported Tools

    • PostgreSQL: Default support with JSONB, BIGSERIAL, and automated updated_at triggers.
    • MySQL: Optimized with UNSIGNED types and AUTO_INCREMENT syntax.
    • SQLite: Lightweight syntax with CHECK constraints for enums.

    Why use this skill

    Unlike generic AI prompts, this skill applies strict 3rd Normal Form (3NF) logic, ensures every table includes audit timestamps and soft-delete support, and handles complex many-to-many junction tables automatically. It doesn't just give you code; it produces a professional SCHEMA.md directory of your entities and relationships for your team.
