Shifty tactician scorns CIA - they're not broken (6)
I believe the answer is:
intact
'not broken' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for intact that I've seen before include "Unbroken and unimpaired" , "Undamaged, not broken" , "Flawless" , "Entire, undamaged" , "Whole and unharmed" .)
