Does this skill respect foreign key constraints?

Yes, the skill analyzes your database schema to ensure all generated data maintains proper relational integrity and respects constraints across all tables.

Is the generated data random or realistic?

The data is realistic. It uses Faker libraries to generate contextually appropriate information like real-looking names, emails, addresses, and dates.

What formats can the seed scripts be generated in?

It can generate scripts in several formats, including standard SQL, JavaScript, and popular ORM formats like TypeORM or Prisma.

Can I specify how many records I need?

Absolutely. You can request specific volumes, such as '100 users with 5 posts each', and the skill will scale the generation accordingly.

Can I use this for existing databases?

Yes, the skill uses tools like Grep and Read to analyze your existing project files and schema definitions before generating the appropriate seeding logic.
