-# AGENTS.md — core-trpc
-
-**Tag:** core-composition
-
-Frontend tRPC platform providing the client and framework-specific providers (Next.js, TanStack). Bridges typed backend (`@repo/core-api`) to frontend applications. Tagged `core-composition` (not `core`) because it transitively reaches features through `core-api`'s `AppRouter` type.
-
-## Responsibilities
-
-- **Create tRPC React client** — `createTRPCReact<AppRouter>()` for use in React apps
-- **Query client factory** — TanStack React Query setup per app
-- **Framework-specific providers** — Next.js App Router provider + TanStack Start provider
-- **No business logic** — purely framework integration
-
-## Must NOT import
-
-- Any feature package (`@repo/auth`, `@repo/blog`, etc.)
-- Any app package
-- `@repo/core-api`, `@repo/core-cms`, `@repo/core-ui`
-
-## Public exports
-
-From `package.json`:
-- `.` — client + query client factory
-- `./next` — Next.js App Router provider
-- `./tanstack` — TanStack Start provider
-
-Example usage:
-```typescript
-// In Next.js app
-import { TrpcProvider } from "@repo/core-trpc/next";
-
-// In TanStack Start app
-import { TrpcProvider } from "@repo/core-trpc/tanstack";
-
-// In client components
-import { useTRPC } from "@repo/core-trpc";
-const trpc = useTRPC();
-```
-
-## Test conventions
-
-- No unit tests (provider layer)
-- Verify at app boot: `pnpm dev --filter @repo/web-next` or `pnpm dev --filter @repo/web-tanstack` succeeds
-- Verify client type safety: `pnpm typecheck` confirms `AppRouter` is imported and typed correctly
-
-## Structure
-
-```
-src/
-  client.ts                  # createTRPCReact<AppRouter>()
-  query-client.ts            # makeQueryClient()
-  providers/
-    next-provider.tsx        # 'use client' provider for Next.js
-    tanstack-provider.tsx    # Provider for TanStack Start
-  index.ts                   # re-exports client + factories
