Agent Skills: trpc

Corrects the wrong defaults a model has for tRPC v11 (verified against 11.18.0). Use when code imports initTRPC, createTRPCContext, createTRPCOptionsProxy, createTRPCReact, httpBatchLink, httpSubscriptionLink, fetchRequestHandler, or TRPCError, or when building routers, procedures, middleware, links, or RSC prefetching. Covers the v10 to v11 drift that makes stale code fail — the React client that flipped to @trpc/tanstack-react-query, transformers moving into links, renamed type exports, observable subscriptions replaced by async generators over SSE — plus the defaults that are unsafe rather than merely stale — uncapped batching, CDN cache headers that serve one user's data to another, stack traces shipped from edge runtimes, and middleware that runs before input validation. NOT for TanStack Query semantics generally (use tanstack-query), Zod schema authoring (use zod), or Next.js App Router routing (use nextjs).
