a3s-box

a3s-box is a Containers & Kubernetes skill for AI agents, published by AI45Lab in the Box repository on GitHub. Skillspace rates a3s-box D (64/100) and it passed the safety scan; the rating is based on static analysis only.

Drive the a3s-box microVM sandbox CLI - a Docker-like runtime that runs OCI/container images in hardware-isolated microVMs (libkrun). Use when the user wants to run, build, exec into, snapshot, or tear down containers with a3s-box, sandbox untrusted or agent-generated code, spin up throwaway isolated environments, or mentions a3s-box / microVM / libkrun / "run this safely in a sandbox". Teaches the box lifecycle, the `--` argv separator, the networking model, and error recovery. Not for plain Docker/Podman (different CLI, same verbs).
