This skill enables Claude to generate realistic test data and database seed scripts for development and testing environments. It uses Faker libraries to create realistic data, maintains relational integrity, and allows configurable data volumes. Use this skill when you need to quickly populate a database with sample data for development, testing, or demonstration purposes. The skill is triggered by phrases like "seed database", "generate test data", "create seed script", or "populate database with realistic data".

TL;DR

Automates creation of seed scripts with realistic test data using Faker libraries and schema analysis.

What Is It

Generates realistic test data for databases.
Respects table relationships and constraints.

Supports multiple data types and formats.

Key Features

Analyzes database schema for structure and relationships.
Uses Faker libraries for realistic data generation.
Maintains foreign key relationships across tables.
Creates configurable seed scripts in SQL or JS.
Ensures data consistency and volume control.
Supports relational integrity in test data.
Integrates with migration and testing frameworks.

How to Use

1.Define the database schema and tables to seed.
2.Specify data volume and relationships needed.
3.Choose output format (SQL, JS, etc.).
4.Run the skill to generate and output the seed script.
5.Apply the script to populate the development database.
