  STIT (sees to it that) semantics is one of the most prominent tools in modal
logic of agency, widely used among both philosophers and responsible AI
scholars. STIT logic surveys the properties of agents seeing to it that some
state of affairs holds without specifying concrete actions by which that state
of affairs is guaranteed. In comparison with other multi-agent modal logics,
the main advantage of STIT theories is expressive power. STIT logic allows to
study not only statements about agents abilities to perform certain actions (as
it is in variations of Coalition Logic or Propositional Dynamic Logic), but
about what choices they make and what they de-facto achieve as well.
  Nevertheless, in some occasions such expressivity may be redundant. This
paper surveys a specific fragment of classical STIT logic, which has only
strategic modal operator, standing for the fact that agent has an ability to
see to it that some state of affairs holds. The neighbourhood semantics for the
fragment is presented, accompanied with the soundness, canoniciy hence strong
completeness results. Furthermore, the paper presents basic considerations on
epistemic extension of the presented fragment.
