sync-demo-seeder

To keep your Drizzle demo seed SQL synchronized, this Skill reads your schema.ts and migration history to detect changes, then updates INSERT statements, TRUNCATE lists, and enum values in your seed file to match the current schema.

When a new NOT NULL column is added to a Drizzle schema, this Skill adds sensible demo values to the corresponding INSERT statements in your seed file, ensuring the demo data remains valid without manual intervention.

Yes, you can automatically update TRUNCATE lists in your SQL seed file. This Skill validates and updates the lists to ensure all user-data tables are included after schema edits or migrations are applied.

Yes, this seed synchronization tool works specifically with TypeScript projects using Drizzle ORM, requiring the schema in src/lib/db/schema.ts and SQL migrations in the drizzle directory.

The seeding process handles deleted tables by removing their corresponding INSERT sections from the seed file, and handles renamed columns by updating INSERT statements to use exact SQL column names from the current schema.

A key limitation is that the Skill enforces strict hexadecimal UUID formats and preserves existing BEGIN/COMMIT transaction boundaries, meaning malformed UUIDs or broken transaction blocks must be corrected to successfully synchronize the demo seed.
