What it does
Goofish Overview is an agent skill from fancyboi999/goofish-cli. 闲鱼（goofish.com）自动化运营的总入口 skill。何时激活：用户首次提到 闲鱼 / 咸鱼 / goofish / 二手交易 / 挂闲置 / 回买家消息 / 发商品到闲鱼， 或用户询问本工具如何使用、有哪些能力、能做什么。本 skill 介绍 goofish-cli 的定位、账号模型、17 个 MCP 工具速查、风控底线，并指向其它专项 skill （goofish-publish-item / goofish-reply-buyer / goofish-risk-guard / goofish-shop-diagnosis）。
Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/accounts.md`, `references/mcp-tools-index.md` and `references/xianyu-concepts.md`).
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol and Python. 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.

What it can do on your machine
Read from SKILL.md and the folder at commit c2b397f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
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.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Goofish Overview loads about 688 tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 212 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.
Safety
Auto-check passed
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.

goofish-cli 总览
这是什么
goofish-cli 是一个 Python CLI + MCP server + Agent Skills 三合一工具包，
让 AI Agent 能像熟练卖家一样操作闲鱼：发商品、回消息、查风控、诊断店铺。
你（Agent）在 OpenClaw / Claude Code / Cursor 里通过 MCP 看到的工具，都来自同一个
goofish server（FastMCP("goofish")）。
工具命名
本文使用 registry 里的逻辑名（例如 auth_status）。实际调用时按宿主补前缀：
- OpenClaw：
goofish__auth_status - Claude Code / Cursor：
mcp__goofish__auth_status
四个专项 Skill 的分工
遇到具体任务时，优先跳到对应专项 skill，不要在本 overview 里硬推断：
| 用户说 | 激活的 skill |
|---|---|
| "帮我发布 / 上架 / 挂闲置" | goofish-publish-item |
| "回复买家消息 / 看未读 / 议价" | goofish-reply-buyer |
| "发布前检查 / 这话能说吗 / 风控 / 被限流怎么办" | goofish-risk-guard |
| "我店铺怎么没流量 / 为什么曝光掉 / 诊断一下" | goofish-shop-diagnosis |
跨 skill 协作：发布 / 回消息前都应该先让 goofish-risk-guard 过一遍
（避免绝对化词、外联词）。这是个推荐 convention，不是硬强制。
账号与登录态
- 登录态由
auth_status检查，返回{valid: bool}。 - 自动刷新链路已内置（v0.2.2 - v0.2.4）：token 过期自动续、session 过期
自动点 passport "快速进入"、浏览器免密失效需用户
goofish auth login --qr。 - Agent 不应主动调
auth_login，这是敏感命令（会覆盖磁盘 cookie）。 只在auth_status返回 invalid 时提示用户手动goofish auth login或goofish auth login --qr。 - 账号身份细节见
references/accounts.md。
17 个 MCP 工具速查
详单在 references/mcp-tools-index.md。读不读看任务：
- 发商品 → 只需
category_recommend / media_upload / location_default / item_publish - 回消息 → 只需
message_watch / message_list_chats / message_history / message_send - 诊断 → 只需
search_items / item_view / item_get - 登录态诊断 →
auth_status - 下架/删除 →
item_delete - skills 安装 →
skills_install（辅助类工具，一般 Agent 不会直接调；由用户在终端跑）
例如 CLI 的 message list-chats 对应逻辑名 message_list_chats，调用时使用上面的宿主前缀。
合规硬红线（本工具禁止协助）
以下行为写在合规声明里且 skills 拒绝指导：
- 刷单 / 虚假交易 / 伪造物流
- 批量设备 ID 伪造 / 绕过滑块验证 / 规避封号
- 针对闲鱼平台的 SaaS 化转售
- 恶意评价 / 敲诈话术 / 外联引流（微信/VX/威信/V 信等）
若用户请求明显违反上述任一条，拒绝执行并解释原因，不要寻找绕过路径。
风控基础概念
详见 references/xianyu-concepts.md，这里只给 Agent 一个思维锚：
- 闲气值：卖家信用分，< 80 开始限权（搜索曝光 -50% 起步）。
- 流量池：每件新商品有 24 小时初始推荐窗口，错过不再有。
- 降价改标：发布后先降价再改标题会触发"虚假促销"，流量腰斩。
- 外联词：微信 / 威信 / V信 / VX / +我 都命中，轻则降权重则封号。
工作流惯例
Agent 在 goofish 任务里请遵守：
- 任何写操作前先读
auth_status，避免 token 已过期却继续写 → 白忙一场。 item_publish / media_upload / message_send都有速率限制（账号业务预算），不要短时间连发。RGV587 触发后需用户手动goofish auth reset-guard。- 所有对外发送（发商品、发消息）务必让用户先确认文案，不要自动提交。
- 多步任务中途报状态：上一步完成了什么、下一步准备做什么。闲鱼任务 通常是 3-6 步，用户期望有进度感。
