Cozy — installing it from scratch. Second video of the series: we set up cozy in an sbx sandbox (Docker's sandbox CLI for macOS and Windows) and look at what the installer actually does.

▪️ The three-command quick start — clone, sbx create, connect
▪️ What each part of sbx create means — the agent image, the kit, the mounted workspace
▪️ Watching a silent install through its log file with sbx exec -it DEMO tail -f
▪️ Inside the installer: the kit's env and network allowlist, Homebrew, then bootstrap.nu — modules, dotfiles, Claude Code + MCP, and a final stamp
▪️ Connecting through WezTerm, and cozy verify to check what landed

One install script works the same in a sandbox, on a plain host, or in a container.
