+# ClaudeDo.App
+
+Desktop entry point for the ClaudeDo application. Configures DI, initializes the database, and launches the Avalonia window.
+
+## Responsibility
+
+- `Program.cs` — STA thread, DI container registration (repositories, services, viewmodels), schema init, Avalonia builder
+- `App.axaml` / `App.axaml.cs` — Avalonia application lifecycle, main window creation, static `ServiceProvider` accessor
+- `ViewLocator.cs` — reflection-based IDataTemplate that maps ViewModels to Views by naming convention
+
+## Dependencies
+
+- Avalonia 12.0.0 (Desktop, Fluent theme, Inter fonts)
+- CommunityToolkit.Mvvm 8.4.1
+- Microsoft.Extensions.DependencyInjection 8.0.1
+- Microsoft.AspNetCore.SignalR.Client 8.0.11
+- Microsoft.Data.Sqlite 8.0.11
+- Project references: ClaudeDo.Data, ClaudeDo.Ui
+
+## DI Registration Pattern
+
+- **Singletons**: SqliteConnectionFactory, all Repositories, WorkerClient, MainWindowViewModel, TaskListViewModel, TaskDetailViewModel, StatusBarViewModel
+- **Transients**: TaskEditorViewModel, ListEditorViewModel (created per dialog)
+
+## Notes
+
+- This project owns the composition root — all wiring happens here
+- ViewLocator resolves `FooViewModel` -> `FooView` by replacing "ViewModel" with "View" in the type name
+- AvaloniaUI diagnostics are conditionally included (DEBUG only)
