Claude Code实战：用Fable模拟5类新用户测试产品

提供了一套结构清晰、可直接复用的 AI 测试 Prompt，将抽象的用户体验优化转化为具体的 AI Agent 协作流程，对开发者极具实操参考价值。
Claude Code tip: before you add one more feature because users aren't coming, have Fable 5.2 send 𝟱 𝘀𝘂𝗯𝗮𝗴𝗲𝗻𝘁𝘀 in as strangers seeing your product for the first time, and fix only what blocks them. Once a stranger can sign up and get the result, write 𝘇𝗲𝗿𝗼 𝗻𝗲𝘄 𝗳𝗲𝗮𝘁𝘂𝗿𝗲𝘀 𝗳𝗼𝗿 𝟳 𝗱𝗮𝘆𝘀. Go find users instead, the way @pashuk's article on One More Feature Syndrome lays out:
Claude Code 技巧：在因为用户不来而打算添加更多功能之前，先让 Fable 5.2 派出 𝟱 个代理子程序，模拟首次接触你产品的陌生访客，只修复阻碍他们的部分。一旦陌生人能够注册并获得结果，就停止开发任何新功能，保持 𝘇𝗲𝗿𝗼 𝗻𝗲𝘄 𝗳𝗲𝗮𝘁𝘂𝗿𝗲𝘀 𝗳𝗼𝗿 𝟳 𝗱𝗮𝘆𝘀（7天内不新增任何功能）。转而去找用户，正如 @pashuk 关于“再多一个功能综合征”的文章所阐述的那样：
→ Day 1, evening: find 3 communities where your users already talk about the problem → Days 2-3: answer other people's questions first, then write one post with no pitch, product mentioned last → Days 4-6: reply to everyone by hand, ask "when did this last happen to you?", then move it to DMs → Day 7: ask everyone you talked to for one more session, an intro to someone else, or payment → Every feature you want to add goes on a list. Open it on day 7
→ 第1天晚上：找到3个你的用户已经讨论该问题的社区 → 第2-3天：先回答别人的问题，然后写一篇不带推销、产品放在最后提及的帖子 → 第4-6天：手动回复每个人，问“这最后一次发生是什么时候？”，然后将对话移至私信 → 第7天：向你交谈过的所有人请求一次额外会议、引荐其他人或付费 → 每个你想添加的功能都列在一个清单上。在第7天打开它
Before you go find users, send this to Claude Code 👇 "Act as my launch QA lead. Spin up 5 subagents, each a different first-time user: 1. The impatient one: skims, clicks the first button, quits at the first error 2. The skeptic: reads pricing, terms and privacy before signing up 3. The mobile user: does everything on a 375px screen on slow 3G 4. The non-native English speaker: only follows what the UI literally says 5. The breaker: pastes junk into forms, hits back mid-flow, double-clicks everything Each one opens the app in a real browser, goes from landing page to first success, and screenshots every moment they get confused, stuck or annoyed. Merge everything into one list ranked by how many users hit it. Fix only what blocks sign-up or the first result, put everything else on a list, then rerun the 5 users to prove it's fixed."
在去找用户之前，把这段话发给 Claude Code 👇 “扮演我的发布 QA 负责人。启动 5 个子代理，每个代表一种不同的首次用户： 1. 急躁型：快速浏览，点击第一个按钮，遇到第一个错误就退出 2. 怀疑型：注册前阅读定价、条款和隐私政策 3. 移动端用户：在慢速 3G 网络的 375px 屏幕上完成所有操作 4. 非英语母语者：仅遵循 UI 字面说明进行操作 5. 破坏者：向表单粘贴垃圾内容，中途点击返回，对所有东西双击 每个代理都在真实浏览器中打开应用，从落地页到首次成功，并截图记录每一个让他们困惑、卡住或恼火的时刻。 将所有发现合并为一个列表，按受影响用户数量排序。只修复阻碍注册或首次结果的障碍，其余全部列入清单，然后重新运行这 5 个用户以证明已修复。”
