Claim agent shows persona (5)
I believe the answer is:
image
'persona' is the definition.
(I know that persona can be written as image)
'claim agent shows' is the wordplay.
'shows' indicates the answer is hidden within the clue.
'IMAGE' can be found hidden inside 'claim agent'.
(Other definitions for image that I've seen before include "Epitome" , "Visible impression" , "Copy" , "Pictorial representation" , "Mental picture; metaphor" .)
