What is the reducing agent in the forward reaction?

H2O2(aq) + 2 HI(aq)--->2 H2O(l)+I2(s)

Since H2O2 can be both a reducing and oxidizing depending. I am confused on what is the reducing agent. Can someone please explain.

Reducting agent is the species that lost electrons (ie,it was oxidized). On the left, I- in HI had one extra electron, on the right, it has none.
