How can I modify a crafted, repaired, or generated item?

[brazen elk]

Skbee

[high tinsel]

or item edit

[earnest geode]

depends on the NBT

if you want to add a name/lore/enchants, skript can do that

if you want to add an NBT compound, use skbee

if you want to create a (single) tag, also skbee

[analog cape]

Using SkBee, how could I add attributes to an item?
