r/opencodeCLI 案例：单提示词生成浏览器内 Ubuntu 桌面（完整提示词 + 可复现产物）

一句话结论

这是一个可完整复现的「单提示词 → 可玩产物」案例：把下方提示词交给 LongCat-2.0（经 OpenCode），它会生成一个在浏览器里可运行、可交互的 Ubuntu 桌面模拟（文件管理器、终端、设置、锁屏、关机动画等），提示词和产物都已公开并可访问。

适用场景

• 适合的任务：验证 LongCat-2.0 的长指令跟随与单次生成大型前端项目的能力；作为"大型 one-shot 前端生成"的基线提示词复用；配合 oneshot-websites skill 在 OpenCode 中一键产出网站

• 不适合的任务：需要多文件工程结构、后端或持久化的项目（该案例为单 HTML 产物）；对产物规模敏感的低配环境

• 适用的模型版本：LongCat-2.0（作者经 OpenRouter 的 meituan/longcat-2.0 模型在 OpenCode 中使用）

• 适用的客户端、Agent 或 API：OpenCode CLI（模型配置见提示词目录 06）；同类提示词也可在 Claude Code / Hermes 中尝试

• 推荐的推理档位和参数：未公开；提示词要求"无 token 预算限制"，长输出档位更合适

可直接使用的内容

原始提示词（PROMPT.md 全文，英文原文）

Create a fully interactive web-based emulation of the Ubuntu desktop that feels like a living operating system rather than a static mockup. Recreate the modern Ubuntu experience — the GNOME-based desktop with Ubuntu's Yaru design language: the top bar with its clock, calendar popover, and system status menu; the left-hand Ubuntu Dock with pinned and running applications; the Activities overview with window spread, search, and workspace switching; the app grid of installed applications; and draggable, resizable, minimizable, maximizable windows with believable focus, layering, and edge-snapping behavior.

Let visitors actually use the machine. They should be able to launch apps from the dock and the app grid, search for apps and files in the Activities overview, move and resize windows, tile them to screen halves, maximize and restore them, minimize to the dock, switch between workspaces, and quit applications. Include a working Files app with a navigable folder hierarchy, breadcrumbs, list/grid views, and file open/preview behavior; a Text Editor that can open, edit, and save documents; a Terminal with a believable shell session that responds to common commands (ls, cd, pwd, cat, echo, uname, neofetch-style system info, apt simulations, and graceful "command not found" handling); a Settings app with real panels — appearance/accent color, wallpaper, displays, Wi-Fi/network, sound, notifications, users, and About — whose changes visibly take effect on the desktop; a Calculator; a web browser shell with start page and tabs; and a Software store front, plus whatever smaller utilities (clock, image viewer, system monitor) make the system feel inhabited. Changing the wallpaper or accent color in Settings should restyle the desktop and windows; the top-bar clock should tick and its calendar should highlight today; notifications should arrive, stack in the notification list, and dismiss; the system status menu should offer volume, network, battery, settings, lock, suspend, restart, and power-off flows — with confirmation dialogs, a lock screen showing the time and wallpaper, and a believable shutdown/boot sequence that returns to the session.

Recreate the whole look and feel with close fidelity: the Yaru palette with its aubergine and warm orange accents, Ubuntu typography and icon styling, window chrome with the circular close/minimize/maximize buttons, rounded corners and layered shadows, the dock's running-dot indicators, urgency and hover behavior, app grid folders and pagination, context menus, tooltips, modal dialogs, toast notifications, focus and selection states, loading and error states, and the characteristic motion of the desktop — window open/close animations, overview and workspace transitions, dock reveal, and snapping previews. Preserve the interface's visual proportions, interaction texture, feedback, personality, and tiny behaviors while making the recreation responsive and enjoyable in a browser, and include the secondary and edge states — empty folders, missing files, unsaved-changes prompts, disconnected Wi-Fi, low battery — that make an operating system feel inhabited, not just the most recognizable screen.

Do not take shortcuts, substitute a cookie-cutter desktop template, or stop at a superficial approximation. This skill imposes no token budget limit, so pursue the recreation down to the smallest meaningful interactions, states, transitions, and edge cases, and keep refining the look, feel, behavior, and atmosphere until the system feels complete, cohesive, and convincingly Ubuntu.

生成结果核实（2026-08-18 采集）

• 访问 https://ubuntu.longcat.demos.sulat.com/：页面标题 "Ubuntu Desktop"，包含 Activities 概览、时钟（实时）、Files、Text Editor、Web、Terminal、Settings、Calculator、System Monitor 等应用，以及 "Welcome to Ubuntu" 提示——产物真实可运行，非静态截图。

• 作者原帖对比参考：同任务下 Kimi K3 的产物在 https://ubuntu.k3.demos.sulat.com/（提示词 https://ubuntu.k3.demos.sulat.com/PROMPT.md），可作跨模型同任务对比。

• 帖子评论区确认：Owl Alpha 即 LongCat-2.0 的发布版（"Yes this is the release version of owl alpha"）；作者推荐搭配 oneshot-websites skill 把产物部署到 Cloudflare Drop / Vercel Drop。

原始数据与复核说明

• 提示词全文逐字抄录自 PROMPT.md（2026-08-18 采集，3565 字符）。

• 演示站仍在线且可交互（采集时页面返回正常 DOM 与应用列表）。

• 同任务 Kimi K3 参考产物存在，支持跨模型比较；但两者均为单一作者自测，非受控实验。

适用边界

• 该提示词极长（约 3.5K 字符）且要求"无 token 预算限制"，普通额度下可能触发输出上限（API 上限 128K tokens 内一般可容纳，但耗时较长）。

• 产物是单文件网页模拟，存在交互细节与真实 Ubuntu 的差距；作者自述为演示，非生产级系统。

• 复现质量依赖模型档位与客户端；本案例经 OpenCode + OpenRouter 渠道完成，官方 API 渠道行为未逐一验证。
