+# ClaudeDo.Ui
+
+Avalonia UI layer: views, viewmodels, converters, and the SignalR client.
+
+## Pattern
+
+MVVM with CommunityToolkit.Mvvm source generators:
+- `[ObservableProperty]` for bindable properties
+- `[RelayCommand]` for commands (supports async and CanExecute)
+- All ViewModels inherit `ViewModelBase` (extends `ObservableObject`)
+
+## Views
+
+- **MainWindow** — 3-column DockPanel layout (lists | tasks | detail) with GridSplitter, status bar at bottom
+- **TaskListView** — ListBox of tasks with add/edit/delete toolbar
+- **TaskDetailView** — Task info, live log output, worktree section (merge/keep/discard)
+- **TaskEditorView** — Modal dialog for task create/edit
+- **ListEditorView** — Modal dialog for list create/edit
+- **StatusBarView** — Connection status indicator, active task display
+
+All views use compiled bindings (`x:DataType`).
+
+## ViewModels
+
+- **MainWindowViewModel** — root coordinator; manages list collection, selected list, dialog creation via `Func<T>` factories
+- **TaskListViewModel** — manages task collection for selected list; handles CRUD, "Run Now"
+- **TaskDetailViewModel** — displays task details, streams live log, controls worktree operations
+- **TaskItemViewModel** / **ListItemViewModel** — lightweight display VMs
+- **TaskEditorViewModel** / **ListEditorViewModel** — dialog VMs with validation
+- **StatusBarViewModel** — connection state and active tasks
+
+## Services
+
+- **WorkerClient** — SignalR client connecting to `http://127.0.0.1:47821/hub`. Auto-reconnect with exponential backoff. Methods: StartAsync, RunNowAsync, CancelTaskAsync, WakeQueueAsync. Events: TaskStarted, TaskFinished, TaskMessage, TaskUpdated, WorktreeUpdated
+
+## Converters
+
+- **StatusColorConverter** — task status string -> color (Queued=Blue, Running=Orange, Done=Green, Failed=Red, Manual=Gray)
+- **ConnectionColorConverter** — connection state -> color (Online=Green, Offline=Red)
+
+## Dialog Pattern
+
+Editor dialogs use `TaskCompletionSource<bool>` — the dialog sets the result on save/cancel, and the caller awaits the TCS.
+
+## Notes
+
+- Context menus are on both list items and task items
+- Right-click selects the item before showing the context menu
+- "Run Now" CanExecute re-evaluates when worker connection state changes
