What a chief of staff does.

A chief of staff reads everything that reaches the leader and decides what the leader needs to see. They keep the running list of what has been asked and what has been promised, and they know, before the leader asks, where each item stands. They prepare each meeting: who will be in the room, what was said the last time, and what the leader owes the people there. They draft what the leader would write, in the leader's own words, and they keep every confidence.

Heads of state have had such a person for centuries, and so have the leaders of the largest companies. A university president or the chief executive of a health system has at most one, and most leaders have none. This is because a good chief of staff is rare and expensive, and the work does not divide. It has to be done by one person who sees everything.

Kyoor is built to do that work for one executive, and then for the office around them. It reads what reaches the executive, keeps the running list, prepares each meeting and drafts each reply, and it does so on the executive's own computer, where the correspondence already lives. When it needs a stronger model, the names are hidden first. It never decides. The executive does, and Kyoor is there so that the decision is the only thing left to do.
