I write a library a while ago that lets you give NPCs complex agendas, so they appear to have independent lives. I have extended that so now the player can control your NPCs.

Tutorial here

It allows the player to use commands like this:

mary, get ring

tell mary to give the ring to the mysterious guy

tell guy to follow me

tell guy to wait

guy, go north

mary, sit on couch

tell mary to stand up

tell mary to go to the garage

You can control what items can be taken and dropped, what happens when an NPC gives an item, and whether the NPC just refuses.

Currently this as in beta testing, so there may well be bugs. Please take a look, and let me what what does not work or should be added/changed.

This sounds really cool. I'll try it for sure. Well done!
