Defective directive defended by agent (6)
I believe the answer is:
flawed
'defective' is the definition.
(I've seen this before)
'directive defended by agent' is the wordplay.
'directive' becomes 'law' (I can't justify this - if you can you should give a lot more credence to this answer).
'defended by' indicates putting letters inside.
'agent' becomes 'fed' (fed is a kind of agent).
'law' placed within 'fed' is 'FLAWED'.
Can you help me to learn more?
(Other definitions for flawed that I've seen before include "Imperfect" , "wrong" , "Blemished; faulty" , "With imperfections" , "Containing blemish or imperfection" .)
