Skeletal means reduced to skin and bone, or barely sketched out. A skeletal figure, a skeletal outline, skeletal remains.
The medical sense is grave and the other is neutral: a skeletal plan is one with the bare structure and no detail, and saying so is a description rather than a complaint. Skeletal remains is the standard term in a police or archaeological report.
