# UI Fixes Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Fix four post-integration issues: raw NDJSON display, missing start feedback, lost live output, and missing config editors + modal theming.

**Architecture:** A new `StreamLineFormatter` in the UI layer parses NDJSON for display. `TaskDetailViewModel` switches from `ObservableCollection<string>` to a single `string` property. Optimistic UI feedback via a local `RunNowRequestedEvent`. Existing editor dialogs get config sections and proper theming.

**Tech Stack:** .NET 8, Avalonia 12 (Fluent dark theme), CommunityToolkit.Mvvm, System.Text.Json, xUnit

**Files:**
- Create: `src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs`
- Create: `tests/ClaudeDo.Ui.Tests/Helpers/StreamLineFormatterTests.cs`

- [ ] **Step 1: Write failing tests for text delta extraction**

```csharp
// tests/ClaudeDo.Ui.Tests/Helpers/StreamLineFormatterTests.cs
using ClaudeDo.Ui.Helpers;

namespace ClaudeDo.Ui.Tests.Helpers;

public class StreamLineFormatterTests
{
    private readonly StreamLineFormatter _sut = new();

    [Fact]
    public void FormatLine_TextDelta_ReturnsTextContent()
    {
        var line = """{"type":"stream_event","event":{"type":"content_block_delta","index":0,"delta":{"type":"text_delta","text":"Hello world"}}}""";
        var result = _sut.FormatLine(line);
        Assert.Equal("Hello world", result);
    }

    [Fact]
    public void FormatLine_ConsecutiveTextDeltas_ReturnEachDelta()
    {
        var line1 = """{"type":"stream_event","event":{"type":"content_block_delta","index":0,"delta":{"type":"text_delta","text":"Hello "}}}""";
        var line2 = """{"type":"stream_event","event":{"type":"content_block_delta","index":0,"delta":{"type":"text_delta","text":"world"}}}""";
        Assert.Equal("Hello ", _sut.FormatLine(line1));
        Assert.Equal("world", _sut.FormatLine(line2));
    }

    [Fact]
    public void FormatLine_ContentBlockStop_ReturnsNewline()
    {
        var delta = """{"type":"stream_event","event":{"type":"content_block_delta","index":0,"delta":{"type":"text_delta","text":"Hi"}}}""";
        var stop = """{"type":"stream_event","event":{"type":"content_block_stop","index":0}}""";
        _sut.FormatLine(delta);
        Assert.Equal("\n", _sut.FormatLine(stop));
    }
}
```

- [ ] **Step 2: Run tests to verify they fail**

Run: `dotnet test tests/ClaudeDo.Ui.Tests --filter "StreamLineFormatterTests" -v quiet`
Expected: Build error — `StreamLineFormatter` does not exist.

- [ ] **Step 3: Write minimal StreamLineFormatter**

```csharp
// src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs
using System.Text.Json;

namespace ClaudeDo.Ui.Helpers;

public sealed class StreamLineFormatter
{
    public string? FormatLine(string ndjsonLine)
    {
        if (string.IsNullOrWhiteSpace(ndjsonLine)) return null;

        try
        {
            using var doc = JsonDocument.Parse(ndjsonLine);
            var root = doc.RootElement;

            if (!root.TryGetProperty("type", out var typeProp)) return null;
            var type = typeProp.GetString();

            return type switch
            {
                "stream_event" => HandleStreamEvent(root),
                _ => null,
            };
        }
        catch (JsonException)
        {
            return ndjsonLine; // Fallback: show raw line
        }
    }

    private static string? HandleStreamEvent(JsonElement root)
    {
        if (!root.TryGetProperty("event", out var evt)) return null;
        if (!evt.TryGetProperty("type", out var evtTypeProp)) return null;
        var evtType = evtTypeProp.GetString();

        return evtType switch
        {
            "content_block_delta" => HandleDelta(evt),
            "content_block_stop" => "\n",
            _ => null,
        };
    }

    private static string? HandleDelta(JsonElement evt)
    {
        if (!evt.TryGetProperty("delta", out var delta)) return null;
        if (!delta.TryGetProperty("type", out var deltaType)) return null;

        return deltaType.GetString() switch
        {
            "text_delta" => delta.TryGetProperty("text", out var text) ? text.GetString() : null,
            _ => null, // input_json_delta etc. — skip
        };
    }
}
```

- [ ] **Step 4: Run tests to verify they pass**

Run: `dotnet test tests/ClaudeDo.Ui.Tests --filter "StreamLineFormatterTests" -v quiet`
Expected: 3 passed.

- [ ] **Step 5: Commit**

```bash
git add src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs tests/ClaudeDo.Ui.Tests/Helpers/StreamLineFormatterTests.cs
git commit -m "feat(ui): add StreamLineFormatter with text delta parsing (TDD)"
```

### Task 3: StreamLineFormatter — tool use, result, system, fallback (TDD)

**Files:**
- Modify: `src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs`
- Modify: `tests/ClaudeDo.Ui.Tests/Helpers/StreamLineFormatterTests.cs`

- [ ] **Step 1: Write failing tests for remaining event types**

Append to `StreamLineFormatterTests.cs`:

```csharp
[Fact]
public void FormatLine_ToolUseStart_ReturnsToolNameLine()
{
    var line = """{"type":"stream_event","event":{"type":"content_block_start","index":1,"content_block":{"type":"tool_use","id":"toolu_xxx","name":"Read","input":{}}}}""";
    var result = _sut.FormatLine(line);
    Assert.Equal("\n[Tool: Read]\n", result);
}

[Fact]
public void FormatLine_InputJsonDelta_ReturnsNull()
{
    var line = """{"type":"stream_event","event":{"type":"content_block_delta","index":1,"delta":{"type":"input_json_delta","partial_json":"{\"file\":"}}}""";
    Assert.Null(_sut.FormatLine(line));
}

[Fact]
public void FormatLine_Result_ReturnsFormattedResult()
{
    var line = """{"type":"result","result":"Task completed successfully.","session_id":"sess_123"}""";
    var result = _sut.FormatLine(line);
    Assert.Equal("\n--- Result ---\nTask completed successfully.\n", result);
}

[Fact]
public void FormatLine_ApiRetry_ReturnsRetryNotice()
{
    var line = """{"type":"system","subtype":"api_retry","message":"Retrying..."}""";
    var result = _sut.FormatLine(line);
    Assert.Equal("\n[Retrying API call...]\n", result);
}

[Fact]
public void FormatLine_SystemNonRetry_ReturnsNull()
{
    var line = """{"type":"system","subtype":"init"}""";
    Assert.Null(_sut.FormatLine(line));
}

[Fact]
public void FormatLine_AssistantType_ReturnsNull()
{
    var line = """{"type":"assistant","message":{"role":"assistant","content":[]}}""";
    Assert.Null(_sut.FormatLine(line));
}

[Fact]
public void FormatLine_MalformedJson_ReturnsRawLine()
{
    var line = "this is not json";
    Assert.Equal("this is not json", _sut.FormatLine(line));
}

[Fact]
public void FormatLine_MessageStartAndDelta_ReturnsNull()
{
    var start = """{"type":"stream_event","event":{"type":"message_start","message":{"id":"msg_xxx"}}}""";
    var delta = """{"type":"stream_event","event":{"type":"message_delta","delta":{"stop_reason":"end_turn"},"usage":{"output_tokens":50}}}""";
    Assert.Null(_sut.FormatLine(start));
    Assert.Null(_sut.FormatLine(delta));
}
```

- [ ] **Step 2: Run tests to verify new tests fail**

Run: `dotnet test tests/ClaudeDo.Ui.Tests --filter "StreamLineFormatterTests" -v quiet`
Expected: Several failures — `FormatLine_ToolUseStart`, `FormatLine_Result`, `FormatLine_ApiRetry` return null instead of expected strings.

- [ ] **Step 3: Extend StreamLineFormatter to handle all event types**

Update the `FormatLine` method's switch expression in `StreamLineFormatter.cs`:

```csharp
return type switch
{
    "stream_event" => HandleStreamEvent(root),
    "result" => HandleResult(root),
    "system" => HandleSystem(root),
    "assistant" => null,
    _ => null,
};
```

Add `HandleStreamEvent` case for `content_block_start`:

```csharp
private static string? HandleStreamEvent(JsonElement root)
{
    if (!root.TryGetProperty("event", out var evt)) return null;
    if (!evt.TryGetProperty("type", out var evtTypeProp)) return null;
    var evtType = evtTypeProp.GetString();

    return evtType switch
    {
        "content_block_start" => HandleBlockStart(evt),
        "content_block_delta" => HandleDelta(evt),
        "content_block_stop" => "\n",
        _ => null,
    };
}
```

Add new methods:

```csharp
private static string? HandleBlockStart(JsonElement evt)
{
    if (!evt.TryGetProperty("content_block", out var block)) return null;
    if (!block.TryGetProperty("type", out var blockType)) return null;

    if (blockType.GetString() == "tool_use" &&
        block.TryGetProperty("name", out var name))
    {
        return $"\n[Tool: {name.GetString()}]\n";
    }
    return null;
}

private static string? HandleResult(JsonElement root)
{
    if (root.TryGetProperty("result", out var resultProp))
    {
        var text = resultProp.GetString();
        if (text is not null)
            return $"\n--- Result ---\n{text}\n";
    }
    return null;
}

private static string? HandleSystem(JsonElement root)
{
    if (root.TryGetProperty("subtype", out var subtype) &&
        subtype.GetString() == "api_retry")
    {
        return "\n[Retrying API call...]\n";
    }
    return null;
}
```

- [ ] **Step 4: Run tests to verify all pass**

Run: `dotnet test tests/ClaudeDo.Ui.Tests --filter "StreamLineFormatterTests" -v quiet`
Expected: 11 passed.

- [ ] **Step 5: Commit**

```bash
git add src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs tests/ClaudeDo.Ui.Tests/Helpers/StreamLineFormatterTests.cs
git commit -m "feat(ui): complete StreamLineFormatter with tool use, result, system events"
```

### Task 4: StreamLineFormatter — FormatFile method (TDD)

**Files:**
- Modify: `src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs`
- Modify: `tests/ClaudeDo.Ui.Tests/Helpers/StreamLineFormatterTests.cs`

- [ ] **Step 1: Write failing test for FormatFile**

Append to `StreamLineFormatterTests.cs`:

```csharp
[Fact]
public void FormatFile_ParsesAllLinesAndReturnsFormattedText()
{
    var dir = Path.Combine(Path.GetTempPath(), "claudedo_test_" + Guid.NewGuid().ToString("N")[..8]);
    Directory.CreateDirectory(dir);
    var filePath = Path.Combine(dir, "test.ndjson");
    try
    {
        var lines = new[]
        {
            """{"type":"stream_event","event":{"type":"content_block_delta","index":0,"delta":{"type":"text_delta","text":"Hello"}}}""",
            """{"type":"stream_event","event":{"type":"content_block_stop","index":0}}""",
            """{"type":"stream_event","event":{"type":"content_block_start","index":1,"content_block":{"type":"tool_use","id":"t1","name":"Edit","input":{}}}}""",
            """{"type":"stream_event","event":{"type":"content_block_stop","index":1}}""",
            """{"type":"result","result":"Done.","session_id":"s1"}""",
        };
        File.WriteAllLines(filePath, lines);

        var result = _sut.FormatFile(filePath);
        Assert.Contains("Hello", result);
        Assert.Contains("[Tool: Edit]", result);
        Assert.Contains("--- Result ---", result);
        Assert.Contains("Done.", result);
    }
    finally
    {
        Directory.Delete(dir, true);
    }
}

[Fact]
public void FormatFile_TrimsLargeContent()
{
    var dir = Path.Combine(Path.GetTempPath(), "claudedo_test_" + Guid.NewGuid().ToString("N")[..8]);
    Directory.CreateDirectory(dir);
    var filePath = Path.Combine(dir, "large.ndjson");
    try
    {
        // Generate enough text deltas to exceed 50k chars
        var lines = new List<string>();
        for (int i = 0; i < 600; i++)
        {
            var chunk = new string('x', 100);
            lines.Add($$"""{"type":"stream_event","event":{"type":"content_block_delta","index":0,"delta":{"type":"text_delta","text":"{{chunk}}\n"}}}""");
        }
        File.WriteAllLines(filePath, lines);

        var result = _sut.FormatFile(filePath);
        Assert.True(result.Length <= 50_000 + 200); // some tolerance for trimming at newline boundary
    }
    finally
    {
        Directory.Delete(dir, true);
    }
}
```

- [ ] **Step 2: Run tests to verify they fail**

Run: `dotnet test tests/ClaudeDo.Ui.Tests --filter "FormatFile" -v quiet`
Expected: Build error — `FormatFile` method does not exist.

- [ ] **Step 3: Implement FormatFile and trimming**

Add to `StreamLineFormatter.cs`:

```csharp
private const int MaxLength = 50_000;

public string FormatFile(string filePath)
{
    var sb = new System.Text.StringBuilder();
    foreach (var line in File.ReadLines(filePath))
    {
        var formatted = FormatLine(line);
        if (formatted is not null)
            sb.Append(formatted);
    }
    return Trim(sb.ToString());
}

public static string Trim(string text)
{
    if (text.Length <= MaxLength) return text;
    var trimStart = text.Length - MaxLength;
    var newlineAfter = text.IndexOf('\n', trimStart);
    if (newlineAfter >= 0 && newlineAfter < trimStart + 200)
        trimStart = newlineAfter + 1;
    return text[trimStart..];
}
```

Add `using System.Text;` to the top of the file.

- [ ] **Step 4: Run tests to verify all pass**

Run: `dotnet test tests/ClaudeDo.Ui.Tests --filter "StreamLineFormatterTests" -v quiet`
Expected: 13 passed.

- [ ] **Step 5: Commit**

```bash
git add src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs tests/ClaudeDo.Ui.Tests/Helpers/StreamLineFormatterTests.cs
git commit -m "feat(ui): add FormatFile and text trimming to StreamLineFormatter"
```

### Task 5: TaskDetailViewModel — replace LiveLines with LiveText

**Files:**
- Modify: `src/ClaudeDo.Ui/ViewModels/TaskDetailViewModel.cs`

- [ ] **Step 1: Replace LiveLines with LiveText and wire formatter**

In `TaskDetailViewModel.cs`, make these changes:

1. Add using at top:
```csharp
using ClaudeDo.Ui.Helpers;
```

2. Replace the LiveLines property (line 40) and MaxLiveLines constant (line 47):

Remove:
```csharp
public ObservableCollection<string> LiveLines { get; } = new();
```
and:
```csharp
private const int MaxLiveLines = 500;
```

Add:
```csharp
[ObservableProperty] private string _liveText = "";
private StreamLineFormatter _formatter = new();
```

3. Update `LoadAsync` (line 69) — replace `LiveLines.Clear()` with:
```csharp
LiveText = "";
_formatter = new StreamLineFormatter();
```

4. Update `Clear` method — replace `LiveLines.Clear()` with:
```csharp
LiveText = "";
_formatter = new StreamLineFormatter();
```

5. Update `OnTaskMessage` (lines 259-265):

Replace entire method:
```csharp
private void OnTaskMessage(string taskId, string line)
{
    if (taskId != _taskId) return;
    var formatted = _formatter.FormatLine(line);
    if (formatted is not null)
    {
        LiveText += formatted;
        if (LiveText.Length > 50_000)
            LiveText = StreamLineFormatter.Trim(LiveText);
    }
}
```

- [ ] **Step 2: Verify build**

Run: `dotnet build src/ClaudeDo.Ui`
Expected: Build succeeded.

- [ ] **Step 3: Commit**

```bash
git add src/ClaudeDo.Ui/ViewModels/TaskDetailViewModel.cs
git commit -m "refactor(ui): replace LiveLines with LiveText + StreamLineFormatter"
```

---

### Task 6: TaskDetailView — TextBox replaces ItemsControl + auto-scroll

**Files:**
- Modify: `src/ClaudeDo.Ui/Views/TaskDetailView.axaml`
- Modify: `src/ClaudeDo.Ui/Views/TaskDetailView.axaml.cs`

- [ ] **Step 1: Replace ItemsControl with TextBox in TaskDetailView.axaml**

Replace lines 107-122 (the "Live Output" section heading through the Border/ItemsControl):

Old:
```xml
<TextBlock Text="Live Output" FontWeight="SemiBold" FontSize="12"
           Foreground="{StaticResource TextSecondaryBrush}" Margin="0,8,0,2"/>
<Border BorderBrush="{StaticResource BorderSubtleBrush}" BorderThickness="1"
        CornerRadius="6" Padding="6" MaxHeight="200">
    <ScrollViewer>
        <ItemsControl ItemsSource="{Binding LiveLines}">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding}" FontFamily="Consolas,Courier New,monospace"
                               FontSize="11" TextWrapping="NoWrap"
                               Foreground="{StaticResource TextPrimaryBrush}"/>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </ScrollViewer>
</Border>
```

New:
```xml
<TextBlock Text="Live Output" FontWeight="SemiBold" FontSize="12"
           Foreground="{StaticResource TextSecondaryBrush}" Margin="0,8,0,2"/>
<Border BorderBrush="{StaticResource BorderSubtleBrush}" BorderThickness="1"
        CornerRadius="6" Padding="6" MaxHeight="300">
    <ScrollViewer x:Name="LiveOutputScroll">
        <TextBox x:Name="LiveOutputBox"
                 Text="{Binding LiveText, Mode=OneWay}"
                 IsReadOnly="True"
                 AcceptsReturn="True"
                 TextWrapping="NoWrap"
                 FontFamily="Consolas,Courier New,monospace"
                 FontSize="11"
                 Foreground="{StaticResource TextPrimaryBrush}"
                 Background="Transparent"
                 BorderThickness="0"
                 Padding="0"/>
    </ScrollViewer>
</Border>
```

- [ ] **Step 2: Add auto-scroll in code-behind**

In `TaskDetailView.axaml.cs`, add an `OnDataContextChanged` override and property-change handler:

Add using:
```csharp
using System.ComponentModel;
```

Add after the `FocusTitle` method:

```csharp
protected override void OnDataContextChanged(EventArgs e)
{
    base.OnDataContextChanged(e);
    if (DataContext is TaskDetailViewModel vm)
    {
        vm.PropertyChanged += OnViewModelPropertyChanged;
    }
}

private void OnViewModelPropertyChanged(object? sender, PropertyChangedEventArgs e)
{
    if (e.PropertyName == nameof(TaskDetailViewModel.LiveText))
    {
        var scroll = this.FindControl<ScrollViewer>("LiveOutputScroll");
        scroll?.ScrollToEnd();
    }
}
```

- [ ] **Step 3: Verify build**

Run: `dotnet build src/ClaudeDo.Ui`
Expected: Build succeeded.

- [ ] **Step 4: Commit**

```bash
git add src/ClaudeDo.Ui/Views/TaskDetailView.axaml src/ClaudeDo.Ui/Views/TaskDetailView.axaml.cs
git commit -m "feat(ui): replace ItemsControl with TextBox for formatted live output"
```

### Task 7: Log reload from disk

**Files:**
- Modify: `src/ClaudeDo.Ui/ViewModels/TaskDetailViewModel.cs`

- [ ] **Step 1: Add log reload to LoadAsync**

In `TaskDetailViewModel.cs`, in `LoadAsync`, after `LogPath = task.LogPath;` (around line 81), add:

```csharp
// Load historical log for completed tasks
if (task.LogPath is not null
    && task.Status is Data.Models.TaskStatus.Done or Data.Models.TaskStatus.Failed
    && File.Exists(task.LogPath))
{
    _formatter = new StreamLineFormatter();
    LiveText = _formatter.FormatFile(task.LogPath);
}
```

Add `using System.IO;` at the top if not already present.

- [ ] **Step 2: Verify build**

Run: `dotnet build src/ClaudeDo.Ui`
Expected: Build succeeded.

- [ ] **Step 3: Commit**

```bash
git add src/ClaudeDo.Ui/ViewModels/TaskDetailViewModel.cs
git commit -m "feat(ui): reload formatted log from disk for completed tasks"
```

### Task 8: WorkerClient — RunNowRequestedEvent

**Files:**
- Modify: `src/ClaudeDo.Ui/Services/WorkerClient.cs`

### Task 9: TaskItemViewModel — IsStarting state

**Files:**
- Modify: `src/ClaudeDo.Ui/ViewModels/TaskItemViewModel.cs`

- [ ] **Step 1: Add IsStarting property and update CanRunNow**

In `TaskItemViewModel.cs`:

Add property after line 16:
```csharp
[ObservableProperty] private bool _isStarting;
```

Update `CanRunNow` (line 83-84):
```csharp
private bool CanRunNow() =>
    _canRunNow() && Status != TaskStatus.Running && !IsStarting;
```

Add method to set starting state (after `Refresh` method):
```csharp
public void SetStarting()
{
    IsStarting = true;
    StatusText = "starting...";
    RunNowCommand.NotifyCanExecuteChanged();
}

public void ClearStarting()
{
    IsStarting = false;

### Task 11: TaskDetailViewModel — start feedback

**Files:**
- Modify: `src/ClaudeDo.Ui/ViewModels/TaskDetailViewModel.cs`

- [ ] **Step 1: Subscribe to RunNowRequestedEvent and TaskStartedEvent**

In `TaskDetailViewModel.cs` constructor, after `worker.TaskUpdatedEvent += OnTaskUpdated;` (line 63):

```csharp
worker.RunNowRequestedEvent += OnRunNowRequested;
worker.TaskStartedEvent += OnTaskStarted;
```

Add the handler methods before `OnTaskMessage`:

```csharp
private void OnRunNowRequested(string taskId)
{
    if (taskId != _taskId) return;
    StatusText = "starting...";
    LiveText = "";
    _formatter = new StreamLineFormatter();

### Task 12: TaskListView — starting state visual

**Files:**
- Modify: `src/ClaudeDo.Ui/Views/TaskListView.axaml`

- [ ] **Step 1: Add starting indicator next to running indicator**

In `TaskListView.axaml`, find the running indicator Ellipse (the orange dot visible when `IsRunning`). After it, add a similar indicator for the starting state. The exact location depends on the layout, but it should be adjacent to the existing status indicators.

Find the `IsRunning` Ellipse and add a sibling for `IsStarting`:

```xml
<!-- Starting indicator (pulsing or different shade) -->
<Ellipse Width="8" Height="8" Fill="#FFD700"
         IsVisible="{Binding IsStarting}"
         HorizontalAlignment="Center" VerticalAlignment="Center"/>
```

Use a gold/yellow color (`#FFD700`) to distinguish "starting" from "running" (orange).

- [ ] **Step 2: Verify build**

Run: `dotnet build src/ClaudeDo.Ui`
Expected: Build succeeded.

- [ ] **Step 3: Commit**

```bash
git add src/ClaudeDo.Ui/Views/TaskListView.axaml
git commit -m "feat(ui): add starting state indicator in task list"

    {
        var agents = await _hub.InvokeAsync<List<AgentInfo>>("GetAgents");
        return agents ?? [];
    }
    catch
    {
        return [];
    }
}

public async Task RefreshAgentsAsync()
{
    await _hub.InvokeAsync("RefreshAgents");
}
```

```

---

### Task 16: ListEditorViewModel — config fields

**Files:**
- Modify: `src/ClaudeDo.Ui/ViewModels/ListEditorViewModel.cs`

- [ ] **Step 1: Add config properties and model mapping**

In `ListEditorViewModel.cs`:

Add using:
```csharp
using ClaudeDo.Ui.Services;
```

Add static model mapping after `CommitTypes`:

```csharp
public static string[] ModelDisplayNames { get; } = ["Sonnet", "Opus", "Haiku"];

private static readonly Dictionary<string, string> ModelToId = new()
{
    ["Sonnet"] = "claude-sonnet-4-6",
    ["Opus"] = "claude-opus-4-6",
    ["Haiku"] = "claude-haiku-4-5",
};

private static readonly Dictionary<string, string> IdToModel =
    ModelToId.ToDictionary(kv => kv.Value, kv => kv.Key);

public static string ModelIdToDisplay(string? modelId) =>
    modelId is not null && IdToModel.TryGetValue(modelId, out var display) ? display : "Sonnet";

public static string? ModelDisplayToId(string display) =>
    ModelToId.TryGetValue(display, out var id) ? id : null;
```

Add config properties after `_windowTitle`:

```csharp
[ObservableProperty] private string _model = "Sonnet";
[ObservableProperty] private string? _systemPrompt;
[ObservableProperty] private AgentInfo? _selectedAgent;

public List<AgentInfo> AvailableAgents { get; set; } = [];
```

Add a `WorkerClient` field and update constructor — but since the ViewModel is created via factory (`Func<ListEditorViewModel>`), the WorkerClient needs to be injected. Add a method to load agents:

```csharp
public async Task LoadAgentsAsync(WorkerClient worker)
{
    AvailableAgents = await worker.GetAgentsAsync();
}
```

Update `InitForEdit` to accept config:

```csharp
public void InitForEdit(ListEntity entity, Data.Models.ListConfigEntity? config)
{
    _editId = entity.Id;
    _createdAt = entity.CreatedAt;
    Name = entity.Name;
    WorkingDir = entity.WorkingDir;
    DefaultCommitType = entity.DefaultCommitType;
    WindowTitle = $"Edit List: {entity.Name}";

    if (config is not null)
    {
        Model = ModelIdToDisplay(config.Model);
        SystemPrompt = config.SystemPrompt;
        SelectedAgentPath = config.AgentPath;
    }
}
```

Add a method to build the config entity for saving:

```csharp
public Data.Models.ListConfigEntity? BuildConfig(string listId)
{
    var modelId = ModelDisplayToId(Model);
    if (modelId is null && SystemPrompt is null && SelectedAgentPath is null)
        return null;

    return new Data.Models.ListConfigEntity
    {
        ListId = listId,
        Model = modelId,
        SystemPrompt = string.IsNullOrWhiteSpace(SystemPrompt) ? null : SystemPrompt.Trim(),
        AgentPath = SelectedAgentPath,
    };
}
```

- [ ] **Step 2: Verify build**

Run: `dotnet build src/ClaudeDo.Ui`
Expected: Build succeeded.

- [ ] **Step 3: Commit**

```bash
git add src/ClaudeDo.Ui/ViewModels/ListEditorViewModel.cs
git commit -m "feat(ui): add model/prompt/agent config fields to ListEditorViewModel"
```

### Task 17: ListEditorView — config section XAML

**Files:**
- Modify: `src/ClaudeDo.Ui/Views/ListEditorView.axaml`

- [ ] **Step 1: Add config section and increase window height**

In `ListEditorView.axaml`, update `Height="280"` to `Height="480"`.

Before the Save/Cancel button StackPanel, add a config section:

```xml
<!-- Divider -->
<Border Height="1" Background="{StaticResource BorderSubtleBrush}" Margin="0,6,0,2"/>

<TextBlock Text="Agent Config" FontWeight="Bold" FontSize="13"
           Foreground="{StaticResource TextPrimaryBrush}"/>

<TextBlock Text="Model" FontWeight="SemiBold"
           Foreground="{StaticResource TextSecondaryBrush}"/>
<ComboBox ItemsSource="{Binding ModelDisplayNames}"
          SelectedItem="{Binding Model}"
          MinWidth="150"/>

<TextBlock Text="System Prompt" FontWeight="SemiBold"
           Foreground="{StaticResource TextSecondaryBrush}"/>
<TextBox Text="{Binding SystemPrompt}"
         PlaceholderText="(optional) Additional system instructions..."
         AcceptsReturn="True" TextWrapping="Wrap" MinHeight="50"/>

<TextBlock Text="Agent File" FontWeight="SemiBold"
           Foreground="{StaticResource TextSecondaryBrush}"/>
<ComboBox x:Name="AgentCombo"
          SelectedValue="{Binding SelectedAgentPath}"
          SelectedValueBinding="{Binding Path}"
          DisplayMemberBinding="{Binding Name}"
          MinWidth="150">
    <ComboBox.Items>
        <!-- Populated from code-behind -->
    </ComboBox.Items>
</ComboBox>
```

Note: The agent ComboBox will need to be populated from code-behind or via `ItemsSource` binding to `AvailableAgents`. Since `AvailableAgents` is a `List<AgentInfo>`, bind it:

```xml
<ComboBox ItemsSource="{Binding AvailableAgents}"
          SelectedValue="{Binding SelectedAgentPath}"
          MinWidth="150">
    <ComboBox.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Name}"/>
        </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>
```

However, since `SelectedValue` binding with a path property requires `SelectedValueBinding`, and Avalonia's ComboBox support differs from WPF, the simpler approach is to bind to a list of agent path strings with display names handled in the ViewModel. Use a list of display strings and map in the VM.

Simpler approach — replace `AvailableAgents` with two parallel properties in the VM:

Actually, the cleanest Avalonia pattern: use `ItemsSource` and handle selection via `SelectedItem` where items are `AgentInfo` records, and map to path in the VM.

Update the ComboBox to:
```xml
<ComboBox ItemsSource="{Binding AvailableAgents}"
          SelectedItem="{Binding SelectedAgent}"
          MinWidth="150">
    <ComboBox.ItemTemplate>
        <DataTemplate x:DataType="svc:AgentInfo">
            <TextBlock Text="{Binding Name}"/>
        </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>
```

This requires adding `xmlns:svc="using:ClaudeDo.Ui.Services"` to the Window element.

And in the ViewModel, change `SelectedAgentPath` to `SelectedAgent`:

```csharp
[ObservableProperty] private AgentInfo? _selectedAgent;
```

Map to/from path in `InitForEdit` and `BuildConfig`:
- `InitForEdit`: `SelectedAgent = AvailableAgents.FirstOrDefault(a => a.Path == config?.AgentPath);`
- `BuildConfig`: use `SelectedAgent?.Path`

Update `ListEditorViewModel` to use `SelectedAgent` instead of `SelectedAgentPath` in `BuildConfig`:
```csharp
AgentPath = SelectedAgent?.Path,
```

### Task 18: Wire ListEditor config loading/saving in MainWindowViewModel

**Files:**
- Modify: `src/ClaudeDo.Ui/ViewModels/MainWindowViewModel.cs` (or wherever list editor is opened)

The list editor is opened from `MainWindowViewModel` (or wherever the "Edit List" action lives). Find where `ListEditorViewModel.InitForEdit` is called and update it to:

1. Load config before opening: `var config = await _listRepo.GetConfigAsync(entity.Id);`
2. Load agents: `await editor.LoadAgentsAsync(_worker);`
3. Call updated `InitForEdit(entity, config)`
4. After save, persist config: 
```csharp
var configEntity = editor.BuildConfig(saved.Id);
if (configEntity is not null)
    await _listRepo.SetConfigAsync(configEntity);
```

- [ ] **Step 1: Find and update list editor call sites**

Search for `InitForEdit` and `InitForCreate` calls for `ListEditorViewModel` in the codebase. Update each call site to load config and agents.

For `InitForCreate`: agents still need to be loaded. Add `await editor.LoadAgentsAsync(_worker);` after `InitForCreate()`.

For `InitForEdit`: add config loading before init:
```csharp
var config = await _listRepo.GetConfigAsync(entity.Id);
await editor.LoadAgentsAsync(_worker);
editor.InitForEdit(entity, config);
```

After save, persist config:
```csharp
var configEntity = editor.BuildConfig(saved.Id);
if (configEntity is not null)
    await _listRepo.SetConfigAsync(configEntity);
```

- [ ] **Step 2: Verify build**

Run: `dotnet build src/ClaudeDo.Ui`
Expected: Build succeeded.

- [ ] **Step 3: Commit**

```bash
git add src/ClaudeDo.Ui/ViewModels/MainWindowViewModel.cs
git commit -m "feat(ui): wire config loading/saving in list editor flow"
```

### Task 19: TaskEditorViewModel — config override fields

**Files:**
- Modify: `src/ClaudeDo.Ui/ViewModels/TaskEditorViewModel.cs`

- [ ] **Step 1: Add config properties with inheritance**

In `TaskEditorViewModel.cs`:

Add using:
```csharp
using ClaudeDo.Ui.Services;
```

Add static model choices (reuse the mapping from ListEditorViewModel):

```csharp
public static string[] ModelChoices { get; } = ["(list default)", "Sonnet", "Opus", "Haiku"];
```

Add config properties after `_windowTitle`:

```csharp
[ObservableProperty] private string _modelChoice = "(list default)";
[ObservableProperty] private string? _systemPromptOverride;
[ObservableProperty] private AgentInfo? _selectedAgent;
public List<AgentInfo> AvailableAgents { get; set; } = [];
```

Add agent loading method:

```csharp
public async Task LoadAgentsAsync(WorkerClient worker)
{
    AvailableAgents = await worker.GetAgentsAsync();
}
```

Update `InitForEdit` to load config overrides (add after `TagsInput = ...` line):

```csharp
ModelChoice = entity.Model is not null
    ? ListEditorViewModel.ModelIdToDisplay(entity.Model)
    : "(list default)";
SystemPromptOverride = entity.SystemPrompt;
SelectedAgent = entity.AgentPath is not null
    ? AvailableAgents.FirstOrDefault(a => a.Path == entity.AgentPath)
    : null;
```

Update `Save` to include config on the entity — in the `Save` method, after building the entity, add:

```csharp
entity.Model = ModelChoice != "(list default)"
    ? ListEditorViewModel.ModelDisplayToId(ModelChoice)
    : null;
entity.SystemPrompt = string.IsNullOrWhiteSpace(SystemPromptOverride) ? null : SystemPromptOverride.Trim();
entity.AgentPath = SelectedAgent?.Path;
```

- [ ] **Step 2: Verify build**

Run: `dotnet build src/ClaudeDo.Ui`
Expected: Build succeeded.

- [ ] **Step 3: Commit**

```bash
git add src/ClaudeDo.Ui/ViewModels/TaskEditorViewModel.cs
git commit -m "feat(ui): add model/prompt/agent override fields to TaskEditorViewModel"

### Task 20: TaskEditorView — config section XAML

**Files:**
- Modify: `src/ClaudeDo.Ui/Views/TaskEditorView.axaml`

- [ ] **Step 1: Add config section and increase height**

In `TaskEditorView.axaml`, update `Height="420"` to `Height="600"`.

Add `xmlns:svc="using:ClaudeDo.Ui.Services"` to the Window element.

Before the Save/Cancel button StackPanel, add:

```xml
<!-- Divider -->
<Border Height="1" Background="{StaticResource BorderSubtleBrush}" Margin="0,6,0,2"/>

<TextBlock Text="Agent Config (overrides)" FontWeight="Bold" FontSize="13"
           Foreground="{StaticResource TextPrimaryBrush}"/>

<TextBlock Text="Model" FontWeight="SemiBold"
           Foreground="{StaticResource TextSecondaryBrush}"/>
<ComboBox ItemsSource="{Binding ModelChoices}"
          SelectedItem="{Binding ModelChoice}"
          MinWidth="150"/>

<TextBlock Text="System Prompt" FontWeight="SemiBold"
           Foreground="{StaticResource TextSecondaryBrush}"/>
<TextBox Text="{Binding SystemPromptOverride}"
         PlaceholderText="(inherits from list)"
         AcceptsReturn="True" TextWrapping="Wrap" MinHeight="50"/>

<TextBlock Text="Agent File" FontWeight="SemiBold"
           Foreground="{StaticResource TextSecondaryBrush}"/>
<ComboBox ItemsSource="{Binding AvailableAgents}"
          SelectedItem="{Binding SelectedAgent}"
          MinWidth="150">
    <ComboBox.ItemTemplate>
        <DataTemplate x:DataType="svc:AgentInfo">
            <TextBlock Text="{Binding Name}"/>
        </DataTemplate>

### Task 21: Wire TaskEditor agents loading

**Files:**
- Modify: `src/ClaudeDo.Ui/ViewModels/TaskListViewModel.cs`

- [ ] **Step 1: Load agents in AddTask and EditTask**

In `TaskListViewModel.cs`:

In `AddTask` method (line 130), after `editor.InitForCreate(CurrentListId, defaultCommitType);`, add:
```csharp
await editor.LoadAgentsAsync(_worker);
```

In `EditTask` method (line 173), after `editor.InitForEdit(entity, taskTags);`, add:
```csharp
await editor.LoadAgentsAsync(_worker);
```

Note: `LoadAgentsAsync` must be called BEFORE `InitForEdit` for the task editor so that `AvailableAgents` is populated when `InitForEdit` tries to find the matching `SelectedAgent`. Reorder:

```csharp
var editor = _editorFactory();
await editor.LoadAgentsAsync(_worker);
editor.InitForEdit(entity, taskTags);
```

Same for `AddTask`:
```csharp
var editor = _editorFactory();
await editor.LoadAgentsAsync(_worker);
editor.InitForCreate(CurrentListId, defaultCommitType);
```

- [ ] **Step 2: Verify build**

Run: `dotnet build src/ClaudeDo.Ui`
