I cross posted a version of what you are looking for here: On ChatGPT's use of "Personality" in its system prompt, and API use - #2 by icdev2dev
On your concern on number of times that an assistant has made a post is absolutely valid. The way in which my framework works, I enable the counting through the Message itself. i.e. I store the orginator as Metadata for the AutoExecSubMessage that goes to the AutoExecSubThread.
Occasionally a SystemFunction counts and posts the results on the thread and the assistants can use those for guidance on when to speak up or shutup.
