复盘一次线上故障
故障复盘的通用版 —— 数据不一致那一类另有专门的一份。
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.
这一份是兜底的：任何一次线上故障都能套，代价是判卷比专门那份粗。
它第一幕不问原因，只逼时间线：埋下的时候、开始出问题、被发现、止住血、彻底解决。四个时长里，发现用了多久最能说明监控行不行，而很多人从来没算过这个数。
还有一条它不会松口：根因不许停在人身上，追到「为什么这个操作能把线上改坏」为止。
趁记得住的时候做，时间线过一周就说不准了。

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.
