Full of agreement, reportedly (6)
I believe the answer is:
packed
'full' is the definition.
('packed' can be a synonym of 'full')
'agreement reportedly' is the wordplay.
'agreement' becomes 'pact' (pact is a kind of agreement).
'reportedly' indicates a 'sounds like' (homophone) clue.
'pact' is a homophone of 'PACKED'.
'of' acts as a link.
(Other definitions for packed that I've seen before include "Arranged clothes in suitcase for travelling" , "Enveloped" , "Crowded" , "Placed clothes etc in suitcase" .)
