Like, a Portal Generator has absolutely no way to go into missions. With, say, a Remote Activator, or a neuralyser, or a CAD, you could work that. ...Especially a CAD, given that they generate (often personalized) text, there would be a clear way for one to communicate.

Looking at the category on the wiki, I can definitely say that a sentient CAD would be the best candidate for this idea, in my opinion.

I'll also second what Nesh said, especially regarding interacting with others. It's fun!

As a writer, the purpose of agents having partners is to give them someone to talk to/argue with. Having characters with different knowledge pools and perspectives lets you convey information to the audience naturally and offer more nuance in the interpretation of the fic, and it provides opportunities for humor and a bit of tension so things don't get boring. So, ask yourself: how is this piece of equipment going to do that? Will it serve the purpose well? For how long?

Also, how did this particular piece of equipment get more sentient than the rest? Even Rule of Funny needs some kind of explanation.

Also also, just to note, it's definitely too soon to ask for Permission. We need to get to know you for a while first (and you need to get to know us!). Try to comment on other people's stories and stuff; that's one of the best ways to make friends with writers. {= )
