This simple CLI tool merges multiple prisma schema files from an input directory and allows you to use fragments by adding a preprocessing layer.

fragment TimeStamps {
    updatedAt DateTime  @updatedAt
    createdAt DateTime  @default(now())
}

model User {
    id String @id @default(cuid())
    ...TimeStamps
}
