/schema Command

Help me work with the Prisma database schema for the Penumbra project.

Schema location: prisma/schema.prisma

Current models:

• User: Clerk-integrated user model with books relationship
• Book: Book model with metadata (ISBN, title, authors, subjects, etc.)

Common schema tasks:

1. Add new fields to existing models
2. Create new models
3. Modify relationships
4. Add indexes for performance
5. Update field types or constraints

After schema changes:

1. Generate migration: npx prisma migrate dev --name <description>
2. Generate Prisma Client: npx prisma generate
3. Update TypeScript types if needed

Ask me what schema changes are needed, or show me the current schema and wait for instructions.
