NPCs that aren’t going to be major, recurring characters don’t need to be nearly as well-defined as major NPCs. For a minor NPC, only define what is absolutely necessary.

Most minor NPCs will have a single aspect, which is just what they are: Guard Dog, Obstructive Bureaucrat, or Enraged Cultist, etc.

If necessary, give them another aspect or two to reflect something interesting about them or a weakness. They may also have a stunt.

Give them one or two skills to describe what they’re good at. You can use skills from the skill list or make up something more specific, like Fair (+2) at Getting into Bar Fights or Great (+4) at Biting People.

Give them zero to three stress boxes; the more they have, the more of a threat they can be. Generally, they have no consequence slots; if they take a hit with more shifts than they can absorb with stress, they are simply taken out. Minor NPCs aren’t meant to stick around.
