The compiler absorbed by objective to improve! (5)
I believe the answer is:
emend
'improve' is the definition.
(emending is a kind of improving)
'the compiler absorbed by objective' is the wordplay.
'the compiler' becomes 'me' (the person who is writing these clues).
'absorbed by' indicates putting letters inside.
'objective' becomes 'end' (I've seen this before).
'me' put within 'end' is 'EMEND'.
'to' is the link.
(Other definitions for emend that I've seen before include "Edit; make alterations to a draft" , "do editorial work" , "Remove faults from" , "Remove errors" , "Make improvements to (text)" .)
