Why it matters

AI-agent sandbox design controls access to files, networks, and secrets, making narrowly scoped permissions important for containing compromised or misdirected agents.

Cosmonic's guide compares virtual machines, microVMs, containers, and WebAssembly sandboxes for AI agents, emphasizing least-authority execution. The guide recommends matching sandbox permissions to workload needs and isolating individual tools behind narrowly scoped interfaces.
