SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manually writing SQL DDL (Data Definition Language) and migration scripts is a tedious, time-consuming, and error-prone process, especially for complex database designs and evolving applications.

Core Features & Use Cases

  • Schema Generation: Automatically create CREATE TABLE statements complete with data types, indexes, foreign keys, and constraints.
  • Migration Files: Generate UP and DOWN migration scripts, facilitating version control and easy rollbacks for database changes.
  • Use Case: You're adding a new feature that requires users and sessions tables. This skill generates the complete SQL DDL, including relationships and indexes, and wraps it in a migration file, saving you from writing boilerplate SQL.

Quick Start

Use the sql-schema-generator skill to create tables for "products" and "orders" with appropriate fields and relationships.

FAQPage Schema
How do I generate SQL migration files for database schema changes?▼

SQL migration files are version-controlled scripts that define database changes with UP and DOWN procedures for rollbacks. This skill automatically generates UP and DOWN migration scripts from your schema requirements, outputting them to a migrations/ directory so you can track and reverse schema changes safely.

Can I automatically create SQL DDL for tables with relationships and constraints?▼

Yes. DDL (Data Definition Language) statements define table structure, indexes, and constraints. This skill generates complete CREATE TABLE statements with foreign keys, indexes, NOT NULL, UNIQUE, and CHECK constraints, eliminating manual SQL boilerplate for complex database designs.

What's the fastest way to build schema for a new feature with multiple tables?▼

Feature-driven schema generation automates table creation across related entities. Describe your feature requirements—such as users and sessions tables—and this skill produces complete SQL DDL with appropriate relationships, indexes, and data types, wrapped in migration files ready to deploy.

Do I need to write rollback procedures manually for database migrations?▼

No. Rollback procedures ensure you can safely revert schema changes. This skill generates paired UP and DOWN migration files automatically, including rollback logic so you can undo database changes without manual scripting.

How do I handle schema changes across evolving applications?▼

Schema migrations manage structural changes as applications grow. This skill produces versioned migration scripts with rollback support, coordinating with database agents to apply CREATE TABLE, INDEX, and constraint changes incrementally while maintaining data integrity.
