I think it's possible that they planned it from the beginning, but I agree with you -- there were not obvious clues that Ward was a mole. In fact, if they HAD planted clues, that would have defeated the entire purpose of the surprise reveal of the entire plot of both Cap 2 and the sequel episode(s) of AoS.
Surprise is exactly what they wanted.
I do not have the behind the scenes knowledge to know when the Cap 2 script was written, or how and when that info would have been conveyed to the AoS writers. So I don't know if they had to adapt their arc based on new info some months ago about Cap 2. But I watched the first 10 or 12 eps closely and I saw no foreshadowing of Ward's double agent status.
