+# Monkeytype AI Coding Instructions
+
+Make the responses extremely concise. Sacrifice grammar for the sake of concision.
+
+## Architecture
+**Monorepo**: pnpm + Turborepo with frontend (Vite + SolidJS), backend (Express + MongoDB + Redis), and shared packages.
+
+## Commands
+All commands support `-fe`, `-be`, `-pkg` suffixes for targeted execution:
+```bash
+pnpm run lint-fe    # Frontend linting
+pnpm run test-be    # Backend + integration tests  
+pnpm run build-pkg  # Packages only
+pnpm run dev        # All workspaces with hot reload
+```
+
+## SolidJS Migration
+Frontend is partially migrated - new components use SolidJS (`.tsx`), legacy code remains vanilla JS. 
+
+## Debug Tips
+- Type/lint errors: Run `pnpm run lint` (OXLint is source of truth, not tsc)
+
+## Key Files
+- `turbo.json`: Task deps and caching
+- `frontend/src/ts/config-metadata.ts`: Config validation rules
+- `packages/contracts/src/index.ts`: API contract structure
+- `packages/funbox/src/list.ts`: All funbox definitions
+- `backend/src/api/routes/index.ts`: ts-rest setup
