Goofish Shop Diagnosis is an agent skill from fancyboi999/goofish-cli. 闲鱼店铺 / 商品诊断 skill。何时激活:用户说"我店铺没流量 / 曝光掉了 / 怎么没人问 / 是不是被限流 / 帮我看看为啥没单 / 哪里出问题了"。功能: 用 searchitems 做"买家视角"查自家商品是否露出 → itemview 拉详情 对比排查 → 按归因清单给出"限流可能性 + 修复建议"。本 skill 纯读, 不做任何写操作——只诊断不修,修留给 goofish-publish-item。
Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/diagnosis-workflow.md`, `references/rank-factors.md` and `references/traffic-drop-causes.md`).
It works with Model Context Protocol. The repository describes itself as: 闲鱼 CLI · 原生支持 MCP · 为 AI Agent 而生 | Goofish (Xianyu) automation CLI · MCP-ready · Built for AI Agents. The licence is Apache-2.0.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit c2b397f. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
mcp__goofish__auth_statusmcp__goofish__search_itemsmcp__goofish__item_viewmcp__goofish__item_getFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Goofish Shop Diagnosis loads about 682 tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 141 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Claude Code / Cursor 调 mcp__goofish__<逻辑名>。frontmatter 的 allowed-tools

纯读 skill——诊断、不修。要修的话跳到 goofish-publish-item。
这是三方工具(闲管家、鱼小铺)没做的一块——它们专注自动化,诊断全靠人看后台。本 skill 的差异化就是"像 SRE 做事后分析一样归因"。
search_items(
keyword="<商品核心词>", # 从用户描述或 item 标题提取
# 可以按地理/价格 filter 更精准
)目的:用卖家视角(登录态)搜和买家一样的关键词,看自家商品是否在前 3 页。
结果判断:
| 情况 | 含义 |
|---|---|
| 商品出现在前 20 条 | 权重正常,不是限流 |
| 商品在 50-100 条 | 权重偏低,可能标题/类目不够优 |
| 完全搜不到(翻 3 页+ 都没有) | 强信号:搜索降权 |
| 用"商品 id"搜能出来,用"关键词"搜不出来 | 和上面一样,搜索降权 |
item_view(item_id=<问题商品>)对比:
详见 references/traffic-drop-causes.md。
Agent 读 item_view 数据 → 在清单里逐项打分 → 找出最可能的原因。
【诊断对象】商品标题 (id=xxxxx)
【当前状态】挂价 XXX,发布 N 天,累计曝光 M
【搜索可见性】
- 核心词 "XX" 搜索:❌ 前 3 页找不到
- 商品 id 搜索:✅ 能找到
【嫌疑归因】
1. 【高可能性】 ⚠️ 降价改标
- 证据:发布后 3 天内改过 2 次价格 + 1 次标题
- 说明:触发"虚假促销"规则,搜索权重 -50%
- 修复:等 7 天让权重恢复;期间不要继续改
2. 【中可能性】 类目偏差
- 证据:类目是"数码-手机",同品实际类目为"数码-手机配件"
- 说明:类目错放降权 -30%
- 修复:重新按 category_recommend 选类目(但要接受一次重新审核)
3. 【低可能性】 图片问题
- 证据:首图 1200x900(非 1:1)
- 说明:首图非 1:1 曝光打折
- 修复:换 1:1 首图
【建议操作】
1. 优先处理降价改标 → 等 7 天观察
2. 7 天后仍无起色 → 按原类目重发(删除旧商品重发新的)
3. 同时换首图❌ 鼓励刷数据(刷流量/刷收藏/刷评论 → 风控秒杀,账号完蛋) ❌ 建议频繁改标题/改价(改动本身就是降权源) ❌ 建议删掉重发(除非有明确理由;频繁删发 = 职业卖家嫌疑) ❌ 建议用多个账号互相收藏(同 IP 关联,饱和式封号素材)
这些诊断不要硬做,建议用户去 App 后台看:
说清楚:"这部分数据 CLI 看不到,你可以去 App 的'卖家中心' → '数据参谋'看"
goofish-cli v0.2.4 是无状态的——它不记你昨天的曝光是多少。所以:
未来版本(Roadmap)加历史落盘后,这个 skill 可以做时序归因。

Run `npx skills add fancyboi999/goofish-cli --skill goofish-shop-diagnosis -a claude-code`. Or copy the skill folder (skills/goofish-shop-diagnosis in fancyboi999/goofish-cli) into .claude/skills/goofish-shop-diagnosis in your project. Claude Code loads it when a task matches its description.
Run `npx skills add fancyboi999/goofish-cli --skill goofish-shop-diagnosis -a codex`. Or copy the skill folder (skills/goofish-shop-diagnosis in fancyboi999/goofish-cli) into .agents/skills/goofish-shop-diagnosis in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add fancyboi999/goofish-cli --skill goofish-shop-diagnosis -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/goofish-shop-diagnosis, .gemini/skills/goofish-shop-diagnosis, .github/skills/goofish-shop-diagnosis and .opencode/skills/goofish-shop-diagnosis in your project.
SKILL.md names no scripts, command-line tools or credentials: Goofish Shop Diagnosis is instructions for the agent only. Its frontmatter pre-approves these tools: mcp__goofish__auth_status, mcp__goofish__search_items, mcp__goofish__item_view, mcp__goofish__item_get.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Goofish Shop Diagnosis is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 682 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3.1k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Goofish Shop Diagnosis: MCP Server Builder (anthropics/skills, 180k stars), MCP Server Builder (shareAI-lab/learn-claude-code, 78k stars), MCP Integration for Plugins (anthropics/claude-plugins-official, 38k stars) and Figma use_figma Plugin API Rules (warpdotdev/warp, 65k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
