OpenAI Agents

Mirrors the OpenAI Agents SDK shape. The SDK routes the agent through framework="openai" and the server's OpenAINormalizer consumes it. Model names without a provider prefix are auto-prefixed with openai/ server-side.

Package	conductor-ai-openai
Namespace	Conductor.AI.OpenAI
Entry point	OpenAIAgent.Builder() / OpenAIAgent.From(...)

dotnet add package conductor-ai-openai

Inside this repo, reference Conductor.AI.OpenAI/Conductor.AI.OpenAI.csproj directly.

Basic agent

using Conductor.AI;
using Conductor.AI.OpenAI;

var agent = OpenAIAgent.Builder()
    .Name("greeter")
    .Instructions("You are a friendly assistant. Keep responses concise.")
    .Model("anthropic/claude-sonnet-4-6")
    .Build();

await using var runtime = new AgentRuntime();
var result = await runtime.RunAsync(agent, "Say hello and share a fun fact about C#.");
result.PrintResult();

Tools

Pass objects whose public methods carry [Tool]; they are scanned via ToolRegistry.FromInstance and become worker tools:

var agent = OpenAIAgent.Builder()
    .Name("multi_tool_agent")
    .Instructions("Use the weather and calculator tools to answer questions.")
    .Model("anthropic/claude-sonnet-4-6")
    .Tools(new WeatherTools())          // [Tool]-annotated object(s)
    .Build();

internal sealed class WeatherTools
{
    [Tool(Name = "get_weather", Description = "Get the current weather for a city.")]
    public string GetWeather(string city) => $"Sunny in {city}.";
}

Use .ToolDefs(...) to add already-built ToolDefs (HTTP, MCP, etc.) — see ../concepts/tools.md.

Handoffs

The OpenAI "handoffs" list of sub-agents the LLM can transfer to:

var triage = OpenAIAgent.Builder()
    .Name("customer_service_triage")
    .Instructions("Triage the request and hand off to the right specialist.")
    .Model("anthropic/claude-sonnet-4-6")
    .Handoffs(orderAgent, refundAgent, salesAgent)
    .Build();

Shortcuts

OpenAIAgent.From(name, model, instructions, params object[] toolObjects) is a one-liner equivalent. A structured-output type name can be set via .OutputType("MyType").

What still applies

The adapter builds a normal Agent, so everything in ../concepts/ still applies and you run it with the same AgentRuntime.
