The recipes and skills stuff is pretty experimental, we're trying to see if we can make this a full environment where agents can just have all the tools they need to build along with full privilege (sudo) because it's inside a microvm!

Why not some of the existing microvm efforts? Cloud Hypervisor and Firecracker both have an excellent reputation for ultra lightweight VM's. Both are usable in the very popular Kata Containers project (as well as other upstart VM's Dragonball, & StratoVirt). In us by for example the CNCF Confidential Containers https://github.com/kata-containers/kata-containers/blob/main... https://confidentialcontainers.org/ There's also smaller efforts such as firecracker-containerd or Virtink, both which bring OCI powered microvms into a Docker like position (easy to slot into Kubernetes), via Firecracker and Cloud Hypervisor respectively. https://github.com/smartxworks/virtink https://github.com/firecracker-microvm/firecracker-container... Poking around under the hood, microsandbox appears to use krun. There is krunvm for OCI support (includes MacOS/
