# Triage tickets with the C# Agent SDK

> Use the C# Agent SDK for a local-tool ticket triage loop that stays inside one .NET service.

Use this recipe when one .NET service should classify or summarize incoming support tickets.

## 1. Install the SDKs

```bash theme={null}
dotnet add package AI.Stats.Sdk
dotnet add package AI.Stats.AgentSdk
```

## 2. Define one internal lookup tool

```csharp theme={null}
var loadTicket = AgentSdk.DefineTool(new Tool(
    Id: "load-ticket",
    Description: "Load one support ticket by id.",
    Parameters: new Dictionary<string, object?>
    {
        ["type"] = "object",
        ["properties"] = new Dictionary<string, object?>
        {
            ["ticketId"] = new Dictionary<string, object?> { ["type"] = "string" },
        },
        ["required"] = new[] { "ticketId" },
    },
    Execute: (input, ctx) => Task.FromResult<object?>(new Dictionary<string, object?>
    {
        ["ticketId"] = "T-1042",
        ["severity"] = "medium",
        ["summary"] = "Customer cannot find preset routing settings.",
    })
));
```

## 3. Create and run the agent

```csharp theme={null}
var agent = AgentSdk.CreateAgent(new AgentDefinition
{
    Id = "ticket-triage-agent",
    Model = "openai/gpt-5.4-nano",
    Instructions = "Use tools when helpful and answer with a short triage summary.",
    Tools = new[] { loadTicket },
});

var result = await agent.Run(new RunOptions
{
    Input = "Review ticket T-1042 and summarize the next action.",
    Client = AgentSdk.CreateGatewayAgentClient(),
});

Console.WriteLine(result.Output);
```

## When this recipe fits

* the workflow sits inside one ASP.NET or worker service
* your local runtime already knows how to fetch internal ticket state
* you want a narrow agent loop before adding queues or approvals
