goofish-publish-item闲鱼发商品 skill。何时激活:用户说"帮我发到闲鱼 / 挂个闲置 / 把 XX 上架 / 发布一件 / 新增商品 / 上新";或说"这个怎么写标题 / 类目该选啥 / 图片够了吗"。
Goofish Publish Item is an agent skill from fancyboi999/goofish-cli. 闲鱼发商品 skill。何时激活:用户说"帮我发到闲鱼 / 挂个闲置 / 把 XX 上架 / 发布一件 / 新增商品 / 上新";或说"这个怎么写标题 / 类目该选啥 / 图片够了吗"。 功能:从 raw 描述 / 图片 → 确认类目 → 生成标题候选 → 风控预检 → 批量传图 → 拿默认地址 → 调用 itempublish 一键发布。核心约束:发送前必须让用户确认文案, 不自动提交;调用 goofish-risk-guard 做发布前扫描。
Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/category-selection.md`, `references/common-pitfalls.md` and `references/image-checklist.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__category_recommendmcp__goofish__media_uploadmcp__goofish__location_defaultmcp__goofish__item_publishmcp__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 Publish Item loads about 928 tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 230 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/skills/goofish-publish-item/SKILL.md (or your agent's skills folder). This skill also uses 4 other files; get the full folder from GitHub.正文使用 auth_status 这类逻辑名。OpenClaw 调 goofish__<逻辑名>;
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:
当你从用户消息中能提取 (商品本体 + 至少一张图 或 对物品的文字描述) 就启动本流程。信息不足时问用户而不是瞎猜。
调 auth_status
valid=true → 继续
valid=false → 不继续;告诉用户: "登录态失效了,请执行 goofish auth login(扫码走 --qr)",停。从对话和用户提供的素材里提取:
| 字段 | 必填 | 来源 |
|---|---|---|
| 核心物品(是什么) | ✅ | 用户描述 / 图片识别 |
| 品牌 + 型号 | ✅ | 用户描述 |
| 成色(X 成新) | ✅ | 用户描述;没说就问 |
| 价格 | ✅ | 用户描述;没说就问 |
| 图片(URL 或本地路径) | ✅ | 用户提供 |
| 瑕疵说明 | 推荐 | 问用户"有没有瑕疵要提一下的" |
| 购买渠道 | 推荐 | 帮写描述更有信服力 |
| 是否可议价 / 底线 | 可选 | 为后续 reply-buyer 做准备 |
| 发货地 | ⚪️ | 不填就调 location_default 兜底 |
缺必填字段就停下来问,不要补默认值。
调 category_recommend(title=候选标题, images_json="[]")
→ 拿到完整类目 DTO;已有上传收据时用 images_json=JSON.stringify(收据数组)结果校验:
按 "品牌 + 核心词 + 属性 + 场景 + 情感" 5 段式生成 3 个候选。详见 references/title-formula.md。
然后调用 goofish-risk-guard 扫描:
把扫描过的候选展示给用户选 / 改。
结构参考 references/title-formula.md 的"描述骨架"段。重点:
for image in 本地图片路径:
调 media_upload(path=image)
收集返回的 {url, width, height}
检查:
总图数 ≤ 9 ?
首图是 1:1 ?(如果不是,提示用户换首图)
张数 ≥ 3 ?(少于 3 张警告但不拦)展示给用户(强制):
【标题】...(最终版)
【类目】catName (catId=XXXX)
【描述】
(全文)
【价格】XXX 元
【图片】9 张,首图 1:1 ✅
【发货地】XX 市 / 默认
【风控扫描】通过 ✅
是否确认发布?等待用户明确回复 "发 / 发吧 / 确认 / OK / 是 / 嗯"。含糊的 "看看" / "嗯" 单字不算确认。
确认后:
调 item_publish(
title=...,
desc=...,
price=...,
images_json=JSON.stringify([{url, width, height}, ...]),
category_json=JSON.stringify(category_recommend 的完整 DTO),
location_json=JSON.stringify(location_default 的完整 DTO)
)发布也可用 images=[本地路径, ...] 自动上传,不能把 CDN URL 当本地路径。已提前上传时复用 images_json,避免重复上传。类目 DTO 必须包含 cat_id/cat_name/channel_cat_id/tb_cat_id,地址采用 selected 字段。缺少身份的类目不能猜补。模型分数不是校准概率,未知值为 null。
成功返回 accepted 与 item_id 后,用 item_get 回读确认。失败返回的 images/category/location 可复用;submission_unknown 必须先核对自己的商品列表,禁止盲目重试。发布和下架共用 item.write 默认 1 次/分钟,上传独立 media.write 默认 9 次/分钟。
❌ 跳过 category_recommend,自己猜 catId ❌ 先发后改(建议用户"先发出去再慢慢改" → 发布后频繁编辑会丢流量池权重) ❌ 省略风控扫描(标题含绝对化词直发 → 100% 降权) ❌ 未确认就发(写操作不可逆,多花 5 秒等用户确认) ❌ 批量发十件不停手(令牌桶 1 件/分钟,连发会触发限流)

Run `npx skills add fancyboi999/goofish-cli --skill goofish-publish-item -a claude-code`. Or copy the skill folder (skills/goofish-publish-item in fancyboi999/goofish-cli) into .claude/skills/goofish-publish-item in your project. Claude Code loads it when a task matches its description.
Run `npx skills add fancyboi999/goofish-cli --skill goofish-publish-item -a codex`. Or copy the skill folder (skills/goofish-publish-item in fancyboi999/goofish-cli) into .agents/skills/goofish-publish-item 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-publish-item -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-publish-item, .gemini/skills/goofish-publish-item, .github/skills/goofish-publish-item and .opencode/skills/goofish-publish-item in your project.
SKILL.md names no scripts, command-line tools or credentials: Goofish Publish Item is instructions for the agent only. Its frontmatter pre-approves these tools: mcp__goofish__auth_status, mcp__goofish__category_recommend, mcp__goofish__media_upload, mcp__goofish__location_default, mcp__goofish__item_publish, 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 Publish Item 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 928 tokens (SKILL.md is roughly 3.7k 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 3.2k tokens, read only when the agent opens those files.
