Description

I am following this Agent Supervisor architecture. In my custom implementation it happens that the same agent may be called several times until an exceptions of maximum number of calls is thrown.

Is there a way to impose that you can't call the same agent twice in a row? Indeed, it doesn't make sense to call twice in a row the same agent.

Yeah you can do this either softly (prompt the supervisor to not repeat) or strictly (override the decision if it violates)
