## AI overview

A hands-on guide to running Claude Code inside Docker Sandboxes. It explains how the microVM, project modes, and network rules affect access, and shows setup, authentication, task execution, review, and cleanup. The author's tests found that direct mode applies edits to the shared project immediately, while clone mode keeps changes separate for review. Network permissions control destinations, but permitted connections can still send readable project data; credentials in accessible files may also remain exposed.
