Certain aspects of the present disclosure are directed to tools actuated by pipe swell. A downhole assembly for a wellbore may be provided. The downhole assembly can include a first sleeve and a second sleeve. The first sleeve can expand from a first position to a second position in response to a first pressure applied to the first sleeve. The first sleeve can contract to the first position in response to a cessation of the first pressure. The second sleeve can be positioned adjacent to the first sleeve to define a swell chamber. The swell chamber can actuate a downhole tool by a pressure stored in the swell chamber by the expansion of the first sleeve.
