Question about "Minions deal #% increased Damage if you've used a Minion Skill Recently"

It's work only if minion skill used by player manualy.
If minion skill unleashed by trigger in item this "Minions deal #% increased Damage if you've used a Minion Skill Recently" not work.
So its work like intended or its bug?

It's a common source of confusion, but the thing isn't that complicated once you get it.

you've used is the core component, "you" in this case is your character and "used" refers to any direct event inflicted by you hitting a keyboard key. Spell trigger is in fact a secondary effect of your initial action, so this is not "you've used" this is "you've triggered".

When mod says "you've used" it refers to "self-cast".
traps, mines, minions, totems are not "you".
a trigger is not "used".

does using convocation trigger this effect?

Yes it does. Convocation is a skill with the minion tag. But not if you automate it.
