Sharing our version of this built on just-bash, AgentFS, and Pyodide: https://github.com/coplane/localsandbox
One nice thing about using AgentFS as the VFS is that it's backed by sqlite so it's very portable - making it easy to fork and resume agent workflows across machines / time.
I really like Amla Sandbox addition of injecting tool calls into the sandbox, which lets the agent generated code interact with the harness provided tools. Very interesting!
Thanks for sharing localsandbox! sqlite-backed VFS for fork and resume workflows is very interesting.
