Goofish Reply Buyer is an agent skill from fancyboi999/goofish-cli. 闲鱼买家消息回复 skill。何时激活:用户说"看看我有没有未读 / 回复下买家 / 有人问 XX 怎么办 / 他要砍价我怎么办 / 帮我回一下消息 / 处理下催付 / 议价策略"。 功能:拉未读会话 → 逐会话拉历史 → 分类意图(询价/议价/催付/售后/外联风险)→ 按卖家预设策略起草回复 → 用户确认后 messagesend。核心约束: 不托管发送权——所有对外消息必须人类点头;调用 goofish-risk-guard 做外联词扫描。
Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/bargain-ladder.md`, `references/intent-classification.md` and `references/tone-guide.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.
7 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__message_list_chatsmcp__goofish__message_historymcp__goofish__message_sendmcp__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 Reply Buyer loads about 805 tokens when it runs, and up to ~3.9k if it reads all its reference files. Until then it costs about 63 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.
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
保留 Claude 权限预批准格式,OpenClaw 不读取该字段。
用户典型输入:
永远不自动发消息。
即使用户说"随便回一下"、"你看着办",也要:
message_send为什么硬要这么做:
message_watch 的长连接事件流不同,单条对话是对外行为,不可逆auth_status → valid=false 直接停,提示用户 auth loginmessage_list_chats(fetch_num=20)返回按活动时间倒序的会话列表,每项含 session_id / 对方昵称 / 最后一条消息预览 / 未读数。 默认短时 WS 会话发现;先检查 metadata_status 和 metadata_errors。身份缺失或摘要过期的会话先补信息,不猜对方身份。 HTTP 的 has_more 不代表整份会话列表完整,短时同步也不能保证发现全部历史会话。 WS 条目的 unread=null 表示未知,不能按零忽略,也不能直接与数字比较。
筛选策略:
对每个选中的 cid:
message_history(cid=session_id, limit=20)20 条基本够分类意图了。太长的会话(50+ 条)拉 30 条。
同时(如果消息提到具体商品 ID):
item_get(item_id=...) # 拿商品的最新状态,价格/标题/是否在售详见 references/intent-classification.md。粗分 5 类:
| 意图 | 典型 | 处理策略 |
|---|---|---|
| 询价 / 基本信息 | "多少钱"、"还在吗"、"在哪发货" | 直接回,参考卖家商品描述 |
| 议价 | "便宜点"、"XXX 行吗" | 按 bargain-ladder.md 阶梯回 |
| 催付 | "已付款"、"明天到吗" | 回发货时间 |
| 售后 | "坏了"、"不对"、"要退款" | 谨慎回,留证据;严重时建议人工介入 |
| 外联 / 风险 | "加个微信"、"走转账" | block + 合规话术替换 |
按意图走不同子流程(各有对应 reference)。
起草完必过 risk-guard 扫描:
goofish-risk-guard 的 external-contact-keywords.md 扫草稿展示格式:
【会话】买家昵称 "xxxxx"(未读 N 条)
【最新来信】
> "原文..."
【意图判定】议价(想砍到 XX 元,距你底线 XX 元)
【草稿回复】
"..."
【风控扫描】通过 ✅
发送这条吗?(y/改/跳过)用户回 "发 / 嗯 / 是 / ok / 1" 才调 message_send。
用户回 "改" → 让他说具体改啥,重新起草。 用户回 "跳过" → 跳到下个会话。
message_send(cid=..., text="...")成功后:
Agent 要模仿用户自己的语气,不要用 AI 常见的书面语:
具体调教见 references/tone-guide.md。
用户说"把所有没付款的催一下"
list_chats 找"已下单未付款"标签的会话不要用 AI 写攻击性回评。

Run `npx skills add fancyboi999/goofish-cli --skill goofish-reply-buyer -a claude-code`. Or copy the skill folder (skills/goofish-reply-buyer in fancyboi999/goofish-cli) into .claude/skills/goofish-reply-buyer in your project. Claude Code loads it when a task matches its description.
Run `npx skills add fancyboi999/goofish-cli --skill goofish-reply-buyer -a codex`. Or copy the skill folder (skills/goofish-reply-buyer in fancyboi999/goofish-cli) into .agents/skills/goofish-reply-buyer 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-reply-buyer -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-reply-buyer, .gemini/skills/goofish-reply-buyer, .github/skills/goofish-reply-buyer and .opencode/skills/goofish-reply-buyer in your project.
SKILL.md names no scripts, command-line tools or credentials: Goofish Reply Buyer is instructions for the agent only. Its frontmatter pre-approves these tools: mcp__goofish__auth_status, mcp__goofish__message_list_chats, mcp__goofish__message_history, mcp__goofish__message_send, 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 Reply Buyer 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 805 tokens (SKILL.md is roughly 3.2k 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.
