Here are some comms that I have found to be much more effective then the normal comms that Sages get.

"Can you heal me?" -> "Do you have your heal?"/"Is your heal up?"

"Revive me" -> "Revive [agent] [location], when you can"

"Jett rebibe me" -> "JETT REBIBE ME"

It doesn't seem like much but it sounds much less condescending and we all know that positivity is best. Sage players are probably the most stressed players, with everyone yelling at them to heal and revive. It doesn't cost anything to ask for them kindly! Don't forget to thank your sage for healing or reviving you either!
