schema-gen

What This Skill Does

The schema-gen skill acts as a highly intelligent database architect for your projects. By providing a natural language description of your application's data requirements, the agent interprets your entity relationships and business logic to generate production-ready database schemas. It abstracts away the boilerplate of writing complex migration files or DDL statements by supporting industry-standard ORMs and query builders like Prisma, Drizzle, and TypeORM, alongside raw SQL for PostgreSQL and MySQL. The tool automatically intelligently infers primary and foreign key constraints, optimizes performance through indexing, and incorporates standard operational fields such as timestamps (created_at, updated_at) and soft delete markers.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal:

clawhub install openclaw/skills/skills/lxgicstudios/ai-schema

Ensure that you have Node.js version 18 or higher installed on your system. Furthermore, you must have a valid OPENAI_API_KEY exported in your environment variables, as the underlying generation logic relies on large language models to parse your natural language inputs and map them to relational models.

Use Cases

• Rapid Prototyping: Quickly bootstrap database layers for MVPs or hackathon projects where speed is critical.
• Schema Migration: Easily convert conceptual data models into specific ORM formats like Drizzle or Prisma without manual code translation.
• Education & Learning: Use the tool to learn how a professional-grade schema structure should look for specific business domains.
• Architecture Refinement: Pass an existing schema description to see how an AI suggests organizing indexes and relationships for better performance.

Example Prompts

1. "Generate a Drizzle schema for a marketplace app including users, vendors, products with categories, and an order management system."
2. "I need a PostgreSQL schema for a healthcare app with patients, appointments, and encrypted medical records. Use soft deletes for all tables."
3. "Create a Prisma schema for a social media platform that includes users, posts, comments, likes, and a follower relationship system."

Tips & Limitations

To get the best results, be as specific as possible in your initial prompt. Define constraints, such as 'unique emails' or 'nullable profile pictures', to ensure the generated code requires minimal modification. Keep in mind that this tool generates code based on probabilistic models; always review the generated schema to ensure it aligns with your specific database engine's syntax and performance requirements before running it in a production environment. While it handles standard relations well, highly custom business logic or complex stored procedures may require manual intervention.
