Hide task information, in part (4)
I believe the answer is:
skin
'hide' is the definition.
(a hide is an animal skin)
'task information in part' is the wordplay.
'in part' indicates a hidden word.
'SKIN' is hidden within 'task information'.
(Other definitions for skin that I've seen before include "What keeps you in" , "Epidermis - peel" , "Dermis" , "coat" , "Scrape, as the knee" .)
