agree with GF, in general
I spend a lot of time in sims as support, and always will, unless otherwise instructed be a competent but lacking in initutive co pilot.
I prompt for standard items and prompt for deviations, but will not prompt with corrective actions.
However sometimes, the circumstances for the sim ride are different: for example, a copilot upgrade who needs to demonstrate full understanding of the operation, and how to operate with low experience, and low hourwed copilot... (very normal corporate operations.)
Very occasionally with Co pilots in Right seat, I am the Captain, and they are only required to demonstrate the handling required for SIR revalidation.
