astute

This term describes a sharp, penetrating intelligence that is specifically geared toward practical advantage and strategic success. It carries a connotation of mental agility and a keen eye for detail, often implying a level of shrewdness that allows a person to navigate social or professional hierarchies effectively.

It is generally positive, though in certain contexts it can lean toward a calculating or opportunistic nature.
