What’s described here isn’t connected to the agentic/AI nature of the software at all. Every single program you run as a regular user could potentially do this.
But in this particular case isn't the problem that it's sending everything in the sandbox? Rather than what it might do in an otherwise un-sandboxed system?
The readme is confusing. You say it has bubblewrap, but you also have an FAQ saying why not to use bubblewrap? Another FAQ says why not to use sandbox-exec for mac, yet the link for mac goes to sandbox-exec?
Imagine if the CLI pulled your SSH keys or other sensitive information by mistake?
Programmers do make such mistakes all the time. I don't want to count on whether "uploading all files it can access" is intentional or a mistake.
