Smith 0.2.5

Run AI-powered C# files using Microsoft.Extensions.AI and Devlooped.Extensions.AI

Example leveraging Grok:

#:package Smith@0.*

// Sample X.AI client usage with .NET
var messages = new Chat()
{
 { "system", "You are a highly intelligent AI assistant." },
 { "user", "What is 101*3?" },
};

IChatClient grok = new GrokClient(Throw.IfNullOrEmpty(Env.Get("XAI_API_KEY")))
 .GetChatClient("grok-3-mini")
 .AsIChatClient();

var options = new GrokChatOptions
{
 ReasoningEffort = ReasoningEffort.High, // or ReasoningEffort.Low
 Search = GrokSearch.Auto, // or GrokSearch.On/GrokSearch.Off
};

var response = await grok.GetResponseAsync(messages, options);

AnsiConsole.MarkupLine($":robot: {response.Text}");

Example using Claude:

#:package Smith@0.*

var client = new Anthropic.AnthropicClient(Throw.
 Env.Get("Claude:Key") ?? throw new InvalidOperationException("Missing Claude:Key configuration."),
 services.GetRequiredService<IHttpClientFactory>().CreateClient("ai")))
 .UseLogging()
 .UseFunctionInvocation();

var builder = App.CreateBuilder(args);
builder.Services.AddChatClient(new );

var app = builder.Build();

var history = new List<ChatMessage> { new ChatMessage(ChatRole.System, Prompts.System) };
var chat = app.Services.GetRequiredService<IChatClient>();

var options = new ChatOptions
{
 ModelId = "claude-sonnet-4-20250514",
 MaxOutputTokens = 1000,
 Temperature = 0.7f,
 Tools = [AIFunctionFactory.Create(() => DateTime.Now, "get_datetime", "Gets the current date and time on the user's local machine.")]
};

AnsiConsole.MarkupLine($":robot: Ready v{ThisAssembly.Info.Version}");
AnsiConsole.Markup($":person_beard: ");
while (true)
{
 var input = Console.ReadLine()?.Trim();
 if (string.IsNullOrEmpty(input))
 continue;

 history.Add(new ChatMessage(ChatRole.User, input));

 try
 {
 var response = await AnsiConsole.Status().StartAsync(":robot: Thinking...",
 ctx => chat.GetResponseAsync(input, options));

 history.AddRange(response.Messages);
 // Try rendering as formatted markup
 try
 {
 if (response.Text is { Length: > 0 })
 AnsiConsole.MarkupLine($":robot: {response.Text}");
 }
 catch (Exception)
 {
 // Fallback to escaped markup text if rendering fails
 AnsiConsole.MarkupInterpolated($":robot: {response.Text}");
 }

 AnsiConsole.WriteLine();
 AnsiConsole.Markup($":person_beard: ");
 }
 catch (Exception e)
 {
 AnsiConsole.WriteException(e);
 }
}

static class Prompts
{
 public const string System =
 """
 Your responses will be rendered using Spectre.Console.AnsiConsole.Write(new Markup(string text))). 
 This means that you can use rich text formatting, colors, and styles in your responses, but you must 
 ensure that the text is valid markup syntax. 
 """;
}

Configuration / Environment Variables

The Env class provides access to the following variables/configuration automatically:

• .env files: in local and parent directories
• ~/.env file: in the user's home directory (%userprofile%\.env on Windows)
• All default configuration sources from App Builder:
  • Environment variables prefixed with DOTNET_.
  • Command-line arguments.
  • appsettings.json.
  • appsettings.{Environment}.json.
  • Secret Manager when the app runs in the Development environment.
  • Environment variables.
  • Command-line arguments.
