Told to create stink (4)
I believe the answer is:
reek
'stink' is the definition.
(I know that reek is a type of stink)
'told to create' is the wordplay.
'told' indicates a 'sounds like' (homophone) clue.
'to create' becomes 'wreak' (wreaking is a kind of creating).
'wreak' is a homophone of 'REEK'.
(Other definitions for reek that I've seen before include "Smell badly" , "Smell bad" , "'Stink, stench (4)'" , "Foul smell; smoke (Sc.)" , "Whiff" .)
