Prisma schema design, connection pooling, and client reuse standards. Save this into .cursor/rules/prisma.mdc in your project repository.

// Prisma Best Practices
- Instantiate a single global PrismaClient instance in development to avoid exhausting connection pools with HMR.
- Always use 'prisma migrate dev' locally and 'prisma migrate deploy' in CI/CD.
- Use select or omit to retrieve only required fields for optimal query performance.
- Leverage interactive transactions for multiple atomic database operations.
