Every prompt is a flag in disguise
这句话精准地概括了 CLI 工具现代化的核心原则。交互式提示虽然对人类友好，但对自动化脚本和 AI Agent 构成了不可逾越的障碍。将其转化为 flag，不仅是为 Agent 开门，更是强迫开发者理清“必需信息”的边界，从而设计出更健壮的接口。

Every prompt is a flag in disguise
大多数开发者认为交互式提示是CLI工具的良好用户体验设计，但作者提出反直觉的观点：每个交互式提示都应该有对应的标志（flag）替代方案。这是因为AI代理无法处理交互式输入，而将所有提示转换为标志不仅支持代理，还使工具更加可编程和可测试。

Implicit state is the Enemy
大多数人认为CLI工具应该利用隐式状态（如当前工作目录）来简化用户操作。但作者认为，所有隐式假设都是AI代理的绊脚石，明确指定所有参数和路径不仅有利于代理，也让人类用户的脚本更加健壮和可预测。

Every prompt is a flag in disguise
大多数人认为交互式提示是CLI工具的最佳实践，因为它能引导用户完成复杂任务。但作者认为，每个交互式提示都应该有对应的命令行标志，因为这种设计让工具既能服务于人类用户，也能被AI代理自动化使用，而不需要额外的API层。

as a more experienced user I know one can navigate much more quickly using a terminal than using the hunt and peck style of most file system GUIs
As an experienced user, this claim strikes me as false.
I often start in a graphical file manager (nothing special, Nautilus on my system, or any conventional file explorer elsewhere), then use "Open in Terminal" from the context menu, precisely because of how much more efficient desktop file browsers are for navigating directory hierarchies in comparison.
NB: use of a graphical file browser doesn't automatically preclude keyboard-based navigation.
