 ## Conventions
 
 - REST API with consistent JSON responses and HTTP status codes
 - EF Core code-first migrations (never edit migrations manually)
+- All entities inherit from `BaseModel` (Id, Created, Updated, Deleted)
+- `AppDbContext` sets `Created`/`Updated` automatically via `ChangeTracker`
+- All timestamps stored as UTC (`DateTime.UtcNow`)
 - DTOs for all API input/output (never expose domain entities directly)
 - FluentValidation for all request validation
 - Async/await throughout the backend
 - Vue 3 Composition API (`<script setup>`) only — no Options API
 - Pinia for frontend state management
+- Never call API directly from Vue components — always use the generated `apiClient.ts`
+
+## NSwag API Client Generation
+
+NSwag runs automatically as a post-build step on `ClaudeTest.API`.
+- Config: `backend/ClaudeTest.API/nswag.json`
+- Output: `frontend/src/api/apiClient.ts` (gitignored, regenerated on each build)
+- Template: Axios — generates one typed client class per controller
+- Uses `$(NSwagExe_Net80)` in the MSBuild target (required for .NET 8)
