复盘一个做了没人用的功能
做出来了没人用 —— 是没人看见，还是看见了不用？
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.
「用户不需要」是最省事也最没用的结论：它把「触达问题」和「需求问题」混成一团，而这两者的补救办法完全相反。
所以这一份先要四个数：多少人看见、多少人点了、多少人用完、多少人第二次还来。第一个断点在哪，根因就在哪。没有埋点也没关系 —— 「查不到」本身就是这次复盘最重要的结论之一，它不会替你圆过去。
最后一幕有一问很多人不敢答：现在把它下线，谁会来找你？

How to use this
The more specific the prompt, the sharper the grading: each specific one carries the root-cause checklist for that kind of situation, and the generic group is the fallback when none of them fits. The system design set grades you on "a benefit with no cost attached means you memorised it"; here the line is different: if you can't give a specific, it's empty.
How to start
- Pick one, open it, copy the prompt.
- Paste it into a brand-new conversation.
- Say in a sentence or two which thing you're going to talk about, then wait for its questions — unlike the system design set, where you say nothing after pasting.

Three traps
- When it starts consoling you, point it back to the "don't praise me" rule — the two retrospectives are the likeliest to summon a model's soothing persona, which turns the whole thing into emotional support rather than a retrospective.
- Cut it off when it tries to complete your answer for you. You say "I don't remember", it offers "probably because the schedule was tight" — and that sentence is no longer your memory.
- Before pasting a CV or a design doc, strip out phone numbers, email addresses and anything your company wouldn't want leaving the building.
Got a proposal to pitch? Start with defending it. Just finished a project or lived through an outage? Do those retrospectives while you still remember. Job hunting? Audit the CV first, then take the lines that survived into the behavioural drill.
