In my use it feels as though this should not be done in advance or in the same prompt, even with reasoning models. It'd be better to make a "double check" MCP that calls your prompt, asks whether anything should be amended in that reply or use as is, amends if needed, then gives answer. What you do not want to do is reposition your context into under-informed persona space, so leave the second-guessing out of the initial context. Instead use it as its own judge. (Doesn't have to be, but could also be an alt model.)
