I think sandboxes are useful, but not sufficient. The whole agent runtime has to be designed to carefully manage I/O effects--and capability gate them. I'm working on this here [0]. There are some similarities to my project in what IronClaw is doing and many other sandboxes are doing, but i think we really gotta think bigger and broader to make this work.
