Question on certain 'moves'

Moves that steal items... (thief, snatch, meh...)
how would that work... (mostly towards NPCs)
If,its already been answered or theres a guide for this already... (do I even need to ask at this point?)
Can you send me in the right direction? (if the moves are to OP/broken ...heheh... should I change it to a different move?)

If you roll an item, you're free to have an NPC hold it then have your character steal it through thief, snatch, covet, etc. You can also steal another character's item, assuming you get their roleplayer's permission. You cannot spawn items into existence through stealing moves, though: you have to have access to the item already.
