The current npc tag description says:
A character in an RPG whose decisions and actions are handled by the game-master or a designated assistant. An initialism that stands for "non-player character."
However, this is a description of the NPC term, not the npc tag. It answers a question "what is an NPC", not "what is the npc tag for".
Compare this with the majority of tags, like the new-gm tag:
Questions about becoming or tutoring a game master
Clearly this description is about what is the new-gm tag for.
So, what should we write in the NPC tag description? What is this tag for?
I was browsing through highest voted 'npc' questions and saw a few examples when the tag is used presumably excessively:
A player always wants to recruit NPCs into the party. How do I handle this?
"Any questions about any situations where NPC are significantly involved" seems too broad.
