haven't thought about multi-agent communication yet. each sandbox is fully isolated which is the point. checkpoints help a bit here though, you can branch multiple agents from the same checkpoint so they all start from the same state.

I think I made a cursory and incorrect assumption. Given this is backed by Apple's Virtualization, it has POSIX compliance and forks/execs are allowed within the sandbox which can support agent parallelization within a sandbox I believe.

Looks like a great project at surface!
