FWIW I think many of us would actually very much love to have an official (or semi official) Claude sandboxing container image base / vm base. I wonder if you all have considered making something like the cowork vm available for that?
Perhaps useful, I discovered: https://github.com/agent-infra/sandbox
> All-in-One Sandbox for AI Agents that combines Browser, Shell, File, MCP and VSCode Server in a single Docker container.
There is this:

It does work but I found pretty quickly that I wanted to base my robot sandbox on an image tailored for the project and not the other way around.
