A law-man confiscates general’s plan of action (6)

I believe the answer is:

agenda

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

'plan of action' is the definition.
'agenda' can be an answer for 'plan' (I've seen this before). I'm not certain of the 'of action' bit.

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for agenda that I've seen before include "List of items for discussion by committee" , "List of matters to be discussed at a meeting" , "Something perhaps hidden" , "List of items to be done" , "Meet to discuss this" .)

I've seen this clue in The Hindu.
