I was looking for a way to NPCs recognize a "revive" command to begin the zapping sequence to bring back to life characters whose look_place appears as "Character McCharacterface is laying here, dead" but aren't corpses yet, GMs will usually respond, puppet, and zap them back to life and charge you a small fee, and you can also pray that a PC is posted at the clinic and can help you, but that is usually not the case. So why not allow NPCs to revive people who have recently dead, and have them automatically charge you an amount (like when you ask them to heal you)? That way we don't have to bother you people nor have characters die simply because no GM was available to puppet a doctor.
In the past GMs have said that if within 30 seconds of trying to revive someone through a NPC there was no response, you could ask over 'xhelp', but to me this sounds like a hack. What if even then, there are no available GMs? It's just immersion breaking when you have the IC means and reasons to rescue a friend (or a foe) from their death, perhaps leading to more indepth RP, you could milk a favour out of them in exchange, instead of creating an awkward scene where everyone yells at the doctor to no avail and the dead person becomes a corpse. This being said, I understand that not all doctors will have IC reasons to revive everyone no matter what, but with some code you can add a sort of blacklist or automatically add a @note with the involved parties when it happens, not to mention that it would be supposed to cost a fee like healing.
