日活涨了 12%
日活涨了 12%，老板让你在周会上讲一讲。
Copy the prompt, then pick a model. It plays the interviewer and asks you through it scene by scene instead of handing you the answer.
On a phone with the app installed, the system opens the app directly. Links cannot open external apps inside WeChat — open it in a browser first.
The copied text ends with the answer key the model grades you against. Don't read it yourself first — working it out on your own is the point.
你要是直接开始解释「可能是新版本的功劳」，它会打断你：你还没确认这个数是真的，就开始解释它了。
第二幕逐条问口径：后台同步算不算、点了推送看三秒算不算、多端怎么去重、爬虫和内部账号排掉没有。六条里你们有几条是有明文规定的——这一问常常就是答案。
第四幕是这一份存在的理由：假设明年全公司的奖金都挂在日活上，一个只想让它好看的人会怎么做？ 说不出三种的，就还没想透这个指标。

How to use this
There is no model answer here — but there are definite wrong answers. Only three things make a case hold up, and every prompt's answer key carries a "common wrong answers" section that is more useful than the checklist itself.
The three things that make it hold up
- You can say whose problem this is and what it is — **with evidence** (not "I think users would want it")
- You can say what success looks like — **and what that number is today** (no baseline, no acceptance criteria)
- You can name the cost and what you gave up — **the hardest one to fake**, which is why every prompt hunts for it
How to start
- Pick a question, open it, copy the prompt.
- Paste it into a brand-new conversation — not one where you already discussed it.
- Say nothing. Wait for its first question.

Three traps
- Don't rush to a solution. More than half the lost points here come from designing before asking — especially describing features before defining what success means.
- Expect to be pushed for numbers. "It'll perform better", "users will like it" get cut off: which metric, what is it today, and when do you look?
- When it starts praising you, point it back to rule five — feeling validated crowds out noticing what you missed.
Start with the north star metric; it underpins everything else. Then pick by what's on your plate: a backlog you can't order → prioritisation; nobody using it or retention sliding → retention and onboarding; need to price something → pricing. Save the experiment review for later, and keep redoing the one about turning a one-line request into a spec — it's the closest to daily work.
