@JeremyECrawford does the necromancer's grim harvest activate when an animated undead makes a kill?

A creature you summon/create/animate with a spell is not a spell. It was summoned/created/animated by a spell. #DnD https://t.co/bUkJ9JlxPU

This is totally inconsistent with the ruling that a Rashaka is immune to Shillelagh and magic stone. Neither of those spells involves summoning, creating, or animating a creature.
