FieldCure.AssistStudio.Controls.WinUI.Anthropic

WinUI 3 ChatPanel integration for the Anthropic SDK — Stream Claude responses directly into a production-ready chat UI with minimal code.

Features

BeginAnthropicTurn — Creates an assistant message bubble and starts streaming with one call.
StreamAnthropicAsync — Pipes RawMessageStreamEvent into ChatPanel rendering (text, thinking blocks, usage tracking).
GetConversationAsAnthropicMessages — Converts the current conversation to Anthropic SDK MessageParam format for the next API call.
Automatic lifecycle — AssistantTurnHandle is IAsyncDisposable. Use await using for guaranteed finalization (message rendering, input restoration).

Scope note. This package is a thin streaming bridge: raw Anthropic SDK events → ChatPanel rendering. Tool-use dispatch, sub-agent delegate_task fan-out, parallel pulse placeholders, and truncation-aware recovery are features of ChatPanel's built-in send flow (when Provider is set directly). When you drive Claude through this adapter with DisableInternalSendFlow="True", those behaviors are the caller's responsibility — you handle tool_use blocks and decide whether to retry on stop_reason=max_tokens.

Install

dotnet add package FieldCure.AssistStudio.Controls.WinUI.Anthropic

This transitively brings in FieldCure.AssistStudio.Anthropic (mapper + converter) and FieldCure.AssistStudio.Controls.WinUI (ChatPanel).

Quick Start

XAML:

<controls:ChatPanel x:Name="ChatPanel" DisableInternalSendFlow="True" />

Code-behind:

using FieldCure.AssistStudio.Controls.Anthropic;

var client = new AnthropicClient { ApiKey = "sk-..." };

ChatPanel.UserMessageSubmitted += async (s, e) =>
{
    await using var handle = ChatPanel.BeginAnthropicTurn("Claude", "claude-sonnet-4-6");
    var conv = ChatPanel.GetConversationAsAnthropicMessages();

    var stream = client.Messages.CreateStreaming(new()
    {
        Model = "claude-sonnet-4-6",
        System = conv.SystemPrompt is not null ? new(conv.SystemPrompt) : null,
        Messages = conv.Messages,
        MaxTokens = 4096,
    });

    await handle.StreamAnthropicAsync(stream);
};

v0.2.0-preview.4: BuildAnthropicParams gains an optional tools list (IList<IAssistTool>? tools) — each tool's ParameterSchema is parsed once and forwarded as the SDK's InputSchema.FromRawUnchecked, so consumers can wire IAssistTool implementations into Anthropic turns without writing the SDK Tool param shape themselves. The companion ChatPanel.AppendToolRoundAsync (in Controls.WinUI 0.22.0) records each multi-round result against the active assistant turn so the SDK-driven flow shows the same inline tool blocks as the internal one. WindowsAppSDK 1.7.* → 2.0.* (floating). Multi-target: net9 dropped (STS EOL 2026-05-12), net10 added — now net8.0-windows + net10.0-windows. Rebuilt against AssistStudio.Anthropic 0.2.0-preview.4, Controls.WinUI 0.22.0 (ChatPanel : IToolContext, AppendToolRoundAsync, pre-init send queue, Plotly inline rendering, ElicitationFieldInfo ns move), Ai.Providers 0.8.0, Core 0.20.0. Canonical reference: in-repo samples/AnthropicSdkSample (now demonstrates 3-tool flow: fetch + schedule_reminder + ask_user).
