All modern agentic harnesses can do this. Nobody uses raw LLM for anything remotely complex. There's always some external system in place. That system is part of the "thought process".
Adjacency doesn't matter here, only what the result of the system of pieces is.
It means having self-control on their action and being aware of them. If you ask a system, it will respond, it cannot choose to not respond (even if the response if "I don't want to response", it still "run", still do the work). If you don't ask a system, it will not respond.
Adjacency is the point of the thread here. Saying "you say X is important to decide if the thing is intelligent/understanding/conscious, so let me just change X in the middle of the discussion and say that X does not matter".
That is exactly my first comment in this thread: I don't care if AI think or whatever, my reaction was about these "counter-arguments" that totally miss the point and make the person who push them ridiculous. If you want to have a counter-argument, you first need to understand the interlocutor, not just spew whatever rebuttal you constructed that answer something unrelated to what the interlocutor brought to the conversation.
