Converts this tool definition into the SDK `Responses.ResponseTool` representation.

```csharp
public sealed class SharePointToolResource
{
    public override Task<ResponseTool> ToAgentToolAsync(
        CancellationToken cancellationToken = default(CancellationToken))
    {
        // ...
    }
}
```

## Parameters

- `cancellationToken` (`CancellationToken`) `optional`
  A cancellation token.

## Returns

## Remarks

This method is called at deploy time, after infrastructure provisioning is complete. Tools that depend on provisioned resources (e.g., Azure AI Search connections) can safely resolve their connection identifiers at this point.
