Prisma

Designs Prisma schemas, writes type-safe queries, and fixes migrations, connection pools, and N+1 relation loads in Node and TypeScript. Use when editing schema.prisma, modeling relations, indexes, enums, JSON or Decimal columns, or choosing between db push, migrate dev and migrate deploy; when a migration drifts, fails, or would drop a column on rename, or a database needs baselining; on errors P2002, P2025, P2024, P2034 or P3009; when connections run out on Lambda, Vercel or behind PgBouncer; when queries are slow or include loads too much; on transaction timeouts, deadlocks and optimistic locking; when Decimal or BigInt break JSON.stringify; for $queryRaw and TypedSQL; when porting $use middleware to client extensions; when prisma generate fails in Docker, Alpine or CI; and for seeding and test isolation. Not for database-server tuning or hand-written SQL (pg, sql), or other ORMs.
