The purpose of this paper is to give a formal account of a kind of agency so far neglected in the field of philosophical modal logic of action: planning agency. In doing this we follow the standard approach of modal logics of agency exemplified by the works of Belnap, Chellas and Pörn. Since we believe there is a close relation between planning, time and indeterminism, we use the theory of branching time as a conceptual framework for investigating the basic features of planning agency. Besides introducing a branching-time semantics, we also provide a calculus sound and complete with respect to this semantics.
