The approach uses declarative configuration to create disposable VMs with shared workspaces, network isolation via bridge networking and NAT, and integration with tools like Claude Code. The setup includes network configuration with systemd-networkd, shared directories for workspaces and Nix store, and project-specific package environments. Claude Skills can automate the creation of new MicroVMs by analyzing existing configurations and generating similar structures. This method enables running untrusted code safely while maintaining minimal maintenance overhead through NixOS's declarative model. ## Full article daily.dev links to this article rather than hosting it.
