只寄一次：這件事，誰做了什麼

這是一封虛構的家用織品報價信。八句話，信封只裝得下三句，寄出就不能改。下面是做它的過程中，四個值得記下來的取捨：AI 提了什麼、我決定了什麼、為什麼。

寫一封只寄一次的信聊聊你的報價信

四個取捨

1. 產品名稱，用「家用織品」

問題: 信裡需要一個產品，名稱要讓人覺得真的買得到。
AI 做的: 先提了「家用布料」。
我決定的: 改成「家用織品」。
為什麼: 要聽起來溫暖、真的買得到的東西，不要中性的佔位詞。

2. 不加「重玩」的網址

問題: 測試時想重來，很自然會想加一個重設的連結。
AI 做的: 提了一個重設網址。
我決定的: 否決。
為什麼: 能重來，「只寄一次」就不成立了。

3. 八句要有強有弱

問題: 原本八句寫得太平均，選的時候不會猶豫，等於沒有取捨。
AI 做的: 照指示重寫，其中四句改得各有個性。
我決定的: 要求改成有強有弱，讓「只能留三句」變成真的選擇。
為什麼: 沒有猶豫，就看不出一個人的判斷。

4. 收尾那一句

問題: 選完三句之後，要不要再說點什麼。
AI 做的: 先提了一句收尾提示。
我決定的: 那一句沒選；等八句改成有強有弱之後，才加上現在這一句：「三句留下來，也決定了買家先看見哪一面的你。」
為什麼: 句子要等選擇真的有分量，才有資格說這種話。

做出來很快；要不要做、做成什麼樣、哪些話不能講，是人在決定。

CASE · ONE SEND

One Send: who did what

This is a fictional quotation letter for home textiles. Eight sentences, an envelope that holds only three, and no edits after sending. Below are four trade-offs worth recording from making it: what the AI proposed, what I decided, and why.

Four trade-offs

1. The product is "home textiles"

Problem: The letter needs a product, and its name has to feel like something you could really buy.
AI did: Proposed "home fabric" first.
I decided: Changed it to "home textiles".
Why: I wanted something warm and plausible to buy, not a neutral placeholder.

2. No "play again" link

Problem: While testing, it is natural to want a reset link.
AI did: Proposed a reset URL.
I decided: Rejected it.
Why: If you can start over, "send once" is no longer true.

3. Some of the eight sentences should be strong, some weak

Problem: The eight sentences were too even. Choosing never made you hesitate, so there was no real trade-off.
AI did: Rewrote them as instructed, giving four of them a distinct character.
I decided: Asked for strong and weak sentences, so that keeping only three becomes a genuine choice.
Why: Without hesitation you cannot see a person's judgment.

4. The closing line

Problem: After you choose three sentences, should the page say anything more?
AI did: First proposed a closing hint.
I decided: I did not pick it. Only after the eight sentences became strong and weak did I add the current line: "The three sentences you kept shape the buyer's first impression of you."
Why: A line like that has to wait until the choice carries real weight.

Making it is fast. Whether to make it, what shape it takes, and which words must not be said: a person decides.

What this page does not claim

The buyer and the letter are fictional. No buyer has seen or answered this letter, and this page says nothing about whether it works.

It records the trade-offs made while building this piece only. It does not say the same choices fit your product or market.
