seed-gen

What This Skill Does

The seed-gen skill acts as an intelligent bridge between your database schema and your development environment. Instead of relying on static, generic "lorem ipsum" fillers that break UI layouts or misleadingly simple test strings, this tool uses OpenAI's models to interpret the context of your data models. When you provide a Prisma schema, it analyzes field types, naming conventions, and relationships, generating meaningful, human-like data that reflects your specific domain. Whether you are building an e-commerce platform that requires realistic inventory descriptions or a social network needing interconnected user profiles, seed-gen ensures that your development database feels alive and production-ready from day one. It handles referential integrity automatically, determining the correct insertion order to ensure that foreign key constraints are satisfied without manual intervention.

Installation

To add this skill to your OpenClaw environment, execute the following command in your terminal:

clawhub install openclaw/skills/skills/lxgicstudios/seed-gen

Ensure that you have Node.js 18+ installed on your system. Before running the tool, you must configure your environment by exporting your OpenAI API key:

export OPENAI_API_KEY=sk-...

No further package installation is required, as the skill is designed to run via npx.

Use Cases

This tool is indispensable during the early stages of application development and UI prototyping. It is perfectly suited for populating development databases when you lack real-world data but need to test performance and edge cases. Developers frequently use it to demo features to stakeholders, ensuring that screens look polished and professional rather than sparse. It is also highly effective for testing database indexing and query performance, as it creates a realistic volume of data that helps identify potential bottlenecks before reaching production.

Example Prompts

1. "Use seed-gen to generate 50 user profiles with valid emails and associated blog posts in my Prisma schema."
2. "I need a set of seed data for my e-commerce schema; please create 20 products across 5 categories with varying prices and descriptions."
3. "Generate a SQL seed file for my current schema that includes 100 entries, ensuring all timestamps fall within the last six months."

Tips & Limitations

Start your development process by generating a small batch of 10-20 records. This allows you to verify that the generated data structure aligns with your UI expectations before scaling up to larger datasets. Because this tool utilizes an external LLM to generate data, it requires an active internet connection and a valid API key. Note that while the tool handles referential integrity well, highly complex recursive relationships or extremely niche custom database types might occasionally require manual review after generation. Always review generated data to ensure it meets your specific security or compliance requirements regarding PII.
