偶发超时，重试一次就好
偶发超时，重试一次就好，两个月了 —— 对方还说他们根本没收到。
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.
每天几十次超时，占比 0.05%，重试几乎总是成功。网络组说链路正常，下游说日志里查不到这些请求。
「重试一次就好」是排查里第二值钱的一句话（第一是「只有一部分」）——它一句话就排除掉一大类原因。想明白它排除了什么，剩下的候选就只有几个了。
这是这批里最容易卡死的一份：答案不在你的系统里，也不在你的变更记录里。留到后面做。

How to use this
It gives you the scene (what the service is, the symptom, when it started, the blast radius) and then goes quiet. You ask questions, request metrics, logs, packet captures, propose hypotheses — it answers from a truth you cannot see.
**It is not allowed to volunteer where to look next.** If you don't ask, it doesn't say — even if you circle for ten minutes. That's deliberate: in real life nobody stands next to you saying "maybe check the flame graph". Troubleshooting *is* the skill of knowing what to ask.
How to start
- Pick one, open it, copy the prompt.
- Paste it into a brand-new conversation.
- It gives you the scene and stops — **now it's your turn to speak.**

Three traps
- Don't read the truth at the end first — that ruins the whole thing.
- Don't start by guessing the cause. Establish the scope first (how much, which part, when it started); scope tells you whether this is a code problem or an environment problem.
- Every scene has planted false leads: an unrelated deploy at the same time, metrics that are effects rather than causes, the textbook suspect waiting for you. The wrap-up tells you how many questions you spent on each.
Start with the P99 one — its diagnostic chain is the cleanest. Then "only some machines", whose lesson is the most reusable of all. Save the intermittent timeout for later: its answer lives outside your own system. The report mismatch needs no systems knowledge at all.
