What specific limitation of a purely reactive agent architecture is addressed by a deliberative agent's design?

A purely reactive agent architecture's specific limitation is its inability to form and execute long-term plans, reason about future consequences, or operate effectively in complex, dynamic, or partially observable environments. A "purely reactive agent" operates solely on the basis of its current percepts, which are direct sensory inputs from the environment, mapping them immediately to actions using pre-programmed condition-action rules. It lacks any internal representation or "internal world model" of the environment beyond the immediate sensory input, possesses no memory of past states, and cannot anticipate future outcomes. This makes it suitable only for sim....
