 The command verifies the key and selected region before writing. Existing files are backed up when changed; use `--dry-run` to preview without a live request. In the interactive wizard, compatible agents that are missing from `PATH` can be installed from a second multi-select list using their official packages or installer scripts. The Hermes install uses its official core CLI stages and skips optional system packages, Node workspace, browser, computer-use, setup, and gateway stages. After installation, mmx applies the MiniMax configuration while preserving installer settings. Agents that fail a platform or prerequisite check are explained and left configuration-only. Non-interactive invocations remain configuration-only, and the command never launches an agent.

 写入前会验证 Key 和所选区域；修改已有文件时会创建备份。可用 `--dry-run` 预览且不会发起联网请求。在交互式向导中，兼容且未在 `PATH` 中检测到的 Agent 会出现在第二个安装多选列表，并通过官方软件包或安装脚本安装。Hermes 仅执行官方核心 CLI 安装阶段，跳过可选系统软件包、Node 工作区、浏览器、计算机控制、初始化和网关阶段。安装完成后，mmx 会保留安装器生成的其他设置并写入 MiniMax 配置。平台或依赖检查不通过的 Agent 会说明原因并保持仅配置。非交互调用仍只写配置，且该命令不会启动 Agent。
