[MCU] How was Red Skull appointed as guardian of the Soul Stone?

We know that the Tesseract sent the Red Skull to Vormir, but what I'm confused about is how exactly did he get the job of protecting the Soul Stone. Who approached him when he came to Vormir, gave him his robe and knowledge of the Stone, and said "this thing's your problem now."?

He seems to have some degree of super knowledge or awareness now, hence his little trick with naming the parents of everyone he meets (and he's available for birthday parties!). 

Possibly he has some connection with the Soul Stone now that's feeding him this information, and also tells him what he must do.
