Query Engine

Build validated, type-safe Prisma queries with automatic result validation.

When to Apply

• User mentions "query engine" or "createRegistry"
• User wants type-safe Prisma queries
• User asks about select/include with validation
• User needs to validate Prisma query results
• User mentions "composable queries"
• User asks about relation queries with Zod

Core Concept

The Query Engine creates composable query builders that:

1. Generate Prisma query objects (select, include)
2. Provide matching Zod schemas for validation
3. Infer TypeScript types automatically
