I'm a little stuck... Click here to teach me more about this clue!

'skilful' is the definition.
(adroit can mean skilful or masterful)

I don't understand how the rest of the clue works.

(Other definitions for adroit that I've seen before include "Canny" , "Skilful, dexterous" , "To raid (anag)" , "Clever, skilful" , "Clever - crafty" .)

I've seen this clue in the Evening Standard.
