Level 3 — Decorates a class to define a collaborative Group Chat team. Team members are defined via properties decorated with [`TeamMemberAttribute`](https://docs.mentoragent.net/api/global/teammemberattribute). The termination condition is defined via a method decorated with [`TeamTerminationConditionAttribute`](https://docs.mentoragent.net/api/global/teamterminationconditionattribute). After approval, the team can hand off to L2 agents via HandoffTo.

```text title="Example"
[MentorTeam(
    Name = "BusinessAnalysisTeam",
    Description = "Business analysis with real data and handoff for execution",
    HandoffTo = ["OrderAgent", "CustomerAgent"])]
public class BusinessAnalysisTeam
{
    [TeamMember(
        Role = "DataAnalyst",
        Tools = [typeof(ReportTools), typeof(OrderTools)],
        Instructions = "Analyze the data...")]
    public object? Analyst { get; set; }

    [TeamMember(Role = "Approver", Instructions = "Give the verdict...")]
    public object? Approver { get; set; }

    [TeamTerminationCondition]
    public bool ShouldTerminate(string lastMessage, string lastSpeaker)
        => lastSpeaker == "Approver" && lastMessage.Contains("APPROVED");
}
