AFAIK Claude doesn't support it, but if you're willing to go the extra mile, you can get creative with some bash script: https://pastebin.com/raw/m9YQ8MyS (generated this a second ago - just to get the point across )

To be clear, I don't do this. I never saw an agent cheat by peeking or something. I really did look through their logs.

I'd be very interested to see claude code and other tools support this pattern when dispatching agents to be really sure.
