Improved and repaired under direction (7)
I believe the answer is:
emended
'improved' is the definition.
(emending is a kind of improving)
'repaired under direction' is the wordplay.
'repaired' becomes 'mended' ('mend' can be a synonym of 'repair').
'under' says to put letters next to each other.
'direction' becomes 'e' (E is an example).
'mended' put after 'e' is 'EMENDED'.
'and' acts as a link.
(Other definitions for emended that I've seen before include "Improved" , "subjected to correction" , "did some editing" , "Altered" , "Made corrections" .)
