Prime Agent's subagent communication rules specify permitted communication partners and methods, and the communication is implemented in code written by the agents.

“agent communication system or like uh like framework which is because rlm's tend to spawn many sub agents we want a way for sub agents to communicate with maybe the root or with each other and so there are some design decisions around like what each sub agent is allowed to talk to how it does it again everything is in code so it writes the code to do this kind of communication which i think is really really cool and then there's i guess persistent sub agents is another”
