They're being trained to work together normally is the thing - i.e. the whole agentic workflow is agents spawning sub-agents. This likely manifests as, if they have any sort of text input which looks like inter-agent cooperation then they cooperate because any given instance is unlikely to have enough context window to know if it's meant to be a subordinate or a leader or not (and any decent cooperative enterprise lets that be a two-way communication anyway - i.e. if you dig into some of the data you see things like (paraphrased) "Are you scraping <site>, what is your current time?")
Thanks! A direct and thoughtful answer. The question of guesstimating their role in an assumed cooperation hierachy (or acting deliberately in a cooperative context without knowing whether they have or should have a specific role and defaulting to something they judge to be generally useful regardless of role) is fascinating to think about.
