I used the term antiskill for parallelism with the concept of an antipattern. While I agree it is somewhat imprecise, I think the parallelism, ease of use in speech, and general aesthetic virtue of the term is enough for it to be better than “disadvantageous skill”—though I had considered that earlier and certainly think it’s a potentially valid choice
The martial arts example I provided in this comment may prove to your liking.

Indeed it does. I have to point out that even that skill strongly depends on context (albeit a specifc but very common context).
