# listing 字段级改动清单：GAN-TS-01（B0DEMO0001）

依据 **4 类根因**（尺码不符、图文不符、破损、预期偏差），覆盖该 SKU 退货的 **100%**；共 **10 段**要改。每段的「依据」都指向 `reason-mix-by-cause.csv` 里的原始原因值，可回查。

> 这不是策略，是 diff：下面每一段都写着「现在是什么 / 改成什么」，照着粘回后台即可。文案是模板 + 你的实测值确定性生成的，没有一句是模型编的。

Install guide

One column per agent, each with a check that proves it installed. If the check fails, it is not installed.

Claude Code

Install to .claude/skills/returns-cost/

mkdir -p .claude/skills
unzip returns-cost.zip -d .claude/skills/

How to verify Open a new session and ask it to list the installed skills — seeing this pack's name means it worked.

For a global install, swap .claude/skills/ for ~/.claude/skills/ so every project of this user sees it.

Codex

Install to ~/.codex/skills/returns-cost/

mkdir -p ~/.codex/skills
unzip returns-cost.zip -d ~/.codex/skills/

How to verify Open a new codex session and ask it to list available skills — this pack showing up means it is live.

Codex only reads ~/.codex/skills/, not the project folder; on another machine you place it again.

Cursor

Install to .cursor/rules/returns-cost.mdc

mkdir -p .cursor/rules
cp returns-cost/SKILL.md .cursor/rules/returns-cost.mdc

How to verify In chat, @ that rule file and ask what the pack's first hard rule is — a correct answer means it loaded.

Cursor has no separate skills folder: rules belong to the project, so you place them again per project — the biggest difference from the other two.

If it will not installNot opening a terminal at all? Paste the whole SKILL.md into the chat. Same result, you just re-paste it each new session.

Full steps and common errors live in the pack's playbook.md; the guides section also has ordering and usage guides。

How to use

4 steps; the first run takes about 10 minutes

1
开工前准备 | 要做 | 怎么做 | 为什么 | |---|---|---| | 定一个时间窗口 | 最近 30 天或 90 天，退货表与销量表**用同一个窗口** | 分母不同期，退货率就是错的；大促后单独看，别混进日常 | | 导三份表 | ① 退货报表 ② 同期的已订购商品销售额（或店铺订单数） ③ 你的商品成本表（售价 + 落地成本） | 没有 ② 就算不出退货率；没有 ③ 第二关直接拒跑 | | 只拿一个类目先试 | 按类目筛，先 20–50 单退货 | 全店几千条一起跑，改稿清单会看不完 | | 确认退货原因列 | 用 Excel 打开，看有没有"原因"这一列，值长什么样（代码还是中文） | 归类全靠它；列名/取值对不上先去规则文件里加同义词 | | 备份 | 原始导出的 CSV 单独存一份 | 后面要重跑、要
2
装配 **Claude Code**：复制到项目的 `.claude/skills/`（没有就先建）。 **Codex CLI**：复制到 `.codex/skills/`。 **没有 shell**：不用装。把三个 `SKILL.md` 依次贴进对话，按里面写的规则手工执行；脚本那几步退化成口头执行，产出要你自己填进 CSV。**注意**：手工执行时第 3 关最容易走样（模板里的变量、路径要自己一个个对），建议还是装脚本。 **只用脚本不装 skill**：也可以。`skills/<名字>/scripts/*.py` 是独立的，`python3 <脚本> --help` 能看全部参数。装完确认（一条动作）：新开一个对话，问 **"列出你现在可用的 skills"**，应看到 `reason-mix`、`cost-
3
触发顺序 四步（第 1 步要跑两次）必须按顺序，原因不是习惯： 1. **先 `reason-mix` 跑全店，再按 SKU 跑一次**。因为第三关改的是**某一个 listing**，而全店的原因占比是多个 SKU 混在一起的。反着做会怎样：拿全店的"破损 46%"去改一个破损只占 9% 的服装 SKU，你会给它加气柱袋和易碎标——白花钱，真问题（尺码）一动不动。 2. **先 `reason-mix`，再 `cost-model`**。第二关的分组与"可售/报废"判定都来自第一关的产出。反着做会怎样：没有 `disposition_class`，报废与折价无法区分，成本会被系统性低估（样例 02 里 9 单有 7 单是整件报废，全按折价算会少算一半多）。 3. **先 `cost-model`，再 `listing-

每一步的输入与输出 ### 第 1 关 `reason-mix`（跑两次） | 项 | 内容 | |---|---| | 输入 | 退货报表 CSV（Amazon：`sku,quantity,reason,customer-comments,detailed-disposition`；Shopify：`sku,quantity,return_reason,return_note,warehouse_grade`）+ 销量表（可选） | | 命令 | `python3 skills/reason-mix/scripts/reason_mix.py --input before/returns.csv --platform amazon --sales before/sku-sales.csv --out after/reason-m

FAQ

How do I install it into my agent?

Unzip the ZIP inside your project and put the folder into your agent skills directory (Claude Code: .claude/skills/, Codex: ~/.codex/skills/), then restart the session.

What does it depend on?

Just an agent that can read files. For images or video, connect your own generation tool; the skill ships with parameter templates.

Can I get a refund?

No no-reason refunds after digital delivery. If files are missing or broken, we verify within 48 hours and replace or refund.
