## Definition

```csharp
namespace Aspire.Hosting;

public static class SquadBuilderExtensions
{
    // ...
}
```

## Methods

- [AddSquad(IDistributedApplicationBuilder, string, string?)](/reference/api/csharp/communitytoolkit.aspire.hosting.squad/squadbuilderextensions/methods.md#addsquad-idistributedapplicationbuilder-string-string) : `IResourceBuilder<SquadResource>` `extension` `ats export` -- Adds a Squad AI-agent team to the distributed application. The lifecycle hook discovers agents from `.squad/team.md` (or the default roster when the file does not exist), publishes `Spawning` to `Active` state transitions visible in the Aspire dashboard, and injects a custom `squad://` descriptor that downstream services can consume as metadata. The Squad resource is a logical dashboard/resource-graph entry; it does not start a server process by itself.
