FieldCure.AssistStudio.Anthropic

Platform-agnostic Anthropic SDK adapter for the AssistStudio ecosystem. Maps Anthropic streaming events to StreamEvent and converts ChatMessage to SDK MessageParam.

License: MIT

Features

  • AnthropicStreamEventMapper — Stateful, per-stream mapper that converts RawMessageStreamEvent to IAsyncEnumerable<StreamEvent>. Handles text deltas, thinking deltas, usage, truncation, and unknown block types gracefully.
  • AnthropicMessageConverter — Converts ChatMessage lists to Anthropic MessageParam format. Extracts system prompts, handles image/text attachments, and groups messages by role.
  • Platform-agnostic — Targets net8.0 and net9.0. No WinUI, no Windows dependency. Use in console apps, ASP.NET, MAUI, or any .NET host.

Install

dotnet add package FieldCure.AssistStudio.Anthropic

Usage

Stream mapping

using FieldCure.AssistStudio.Anthropic;

var mapper = new AnthropicStreamEventMapper();
var sdkStream = client.Messages.CreateStreaming(params);

await foreach (var evt in mapper.MapAsync(sdkStream))
{
    switch (evt)
    {
        case StreamEvent.TextDelta td:
            Console.Write(td.Text);
            break;
        case StreamEvent.ThinkingDelta tk:
            // extended thinking content
            break;
        case StreamEvent.Usage u:
            Console.WriteLine($"Tokens: {u.TokenUsage.TotalTokens}");
            break;
        case StreamEvent.StreamCompleted sc:
            Console.WriteLine(sc.IsTruncated ? "(truncated)" : "(done)");
            break;
    }
}

Message conversion

var result = AnthropicMessageConverter.Convert(messages);

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