Ln 723 Seed Data Generator

levnikolaevich/claude-code-skills

Generates realistic seed data from existing ORM schemas (Drizzle, Prisma, EF Core, etc.) or from scratch if you're starting fresh. Outputs to C#, TypeScript, Python, JSON, or SQL with proper faker integration and deterministic seeding so you get the same data every run. The workflow handles relationship ordering automatically so foreign keys don't blow up. Honestly, the dual mode approach (migrate from existing vs. generate new) makes this more versatile than most seed generators that only work with one ORM. Saves you from writing boilerplate test data by hand, and the type mapping tables cover edge cases you'd otherwise forget about until runtime.
