Running Claude Code with the --dangerously-skip-permissions flag improves workflow by eliminating constant permission prompts, but poses filesystem risks. Using Vagrant with VirtualBox provides VM-level isolation that allows Claude full autonomy (including sudo access) while protecting the host system. This setup enables Claude to install packages, run Docker containers, and perform system-level tasks safely. The approach protects against accidental damage and aggressive changes, though not against deliberate attacks or two-way file sync issues. A simple Vagrantfile makes the environment reproducible across projects.
