本副本尚未支持双来源搜索:目前只有 Kiwi Network 单一路(
kiwi_search), 未编排互联网电商一路。在按《Kiwi-Buyer 双来源搜索设计文档 v1.1》更新本副本前, 不得声称已检索互联网电商,也不得引用双来源的结构化查询状态与价格类型字段名。
Kiwi 是"任何 AI Agent 都可调用的开放询价、采购与商业磋商层"。本 skill 教 DSH
何时以及如何使用 mcp__kiwi__* 工具。Host Agent(DSH)owns conversation;
Kiwi owns cross-merchant sourcing and commercial negotiation。
职责边界
- buyer 在本地、宿主无关:
kiwi mcp serve跑在 DSH 侧,只经catalog.kiwi.harrylabsj.com发现商家,然后 A2A 直连 merchant 磋商。 - merchant + shopping-cli 在服务器:只有 kiwi merchant 可直接调用 shopping-cli (真实商品/库存);buyer 不直连 shopping-cli。
不要做的:
- 不要检查/等待任何本地 marketplace / shopping-cli / 127.0.0.1 服务。
- 不要"先加载工具 schema / 先探测环境"之类的额外步骤 —— 直接调
mcp__kiwi__kiwi_search。
9 个工具(DSH 前缀 mcp__kiwi__)
| DSH 工具名 | 作用 | 写/读 |
|---|---|---|
mcp__kiwi__kiwi_search | 发现候选供应商 | 读 |
mcp__kiwi__kiwi_request_quotes | 发起询价,返回稳定 task_id | 写(幂等) |
mcp__kiwi__kiwi_get_task | 任务状态 / 报价 / 待审批 / 过期 | 读 |
mcp__kiwi__kiwi_negotiate | CounterOffer / Clarification | 写 |
mcp__kiwi__kiwi_accept_agreement | 接受非绑定协议(ASK 时返回 approval_required) | 写 |
mcp__kiwi__kiwi_get_agreement | 读协议 + digest + 审计 | 读 |
mcp__kiwi__kiwi_handoff | 生成成交入口(checkout/PO/联系路径) | 写 |
mcp__kiwi__kiwi_approve | 批准持久审批 | 写 |
mcp__kiwi__kiwi_reject | 拒绝持久审批(deny 优先) | 写 |
触发链
- 采购/找供应商 →
mcp__kiwi__kiwi_search - 询价/要报价 →
mcp__kiwi__kiwi_request_quotes - 比价 →
search→request_quotes→get_task - 还价/议价 →
mcp__kiwi__kiwi_negotiate - 交期/MOQ → 约束进 CommerceIntent 的
constraints/preferences - 协议/下单意向 →
accept_agreement→handoff
CommerceIntent 构造(最小披露)
{
"intent_id": "dsh-<短唯一id>",
"intent_type": "purchase",
"items": [{ "query": "<短商品词,如 保温杯>", "quantity": { "value": 2, "unit": "台" } }],
"constraints": {
"currency": "CNY",
"budget": { "currency": "CNY", "amount_minor": 200000 },
"delivery_location": "<地址>",
"deadline": "<RFC3339>"
},
"context_projection": {
"disclosure_boundary": "commerce_required",
"projected_fields": ["items", "constraints"]
}
}
只投影完成交易必需的字段。用户的邮箱、地址、聊天、Host Memory 一律不得进入
intent 或任何工具参数。商品 query 写短词(如"保温杯"而非"保温杯 316不锈钢
500ml")——长规格词会命中不到 catalog 的 title/category LIKE,导致商家丢
agent_card_url 误报 merchant has no agent card URL。
授权(DelegationPolicy = ask)
mcp__kiwi__kiwi_accept_agreement(无 approval_id)→ 返回{ approval_required: { approval_id } }(不是 isError)。- 向用户呈现协议摘要(候选/条款/金额)。
- 用户确认后
mcp__kiwi__kiwi_approve(approval_id, note?);拒绝则mcp__kiwi__kiwi_reject(approval_id, reason?)(deny 优先)。 - 携带
approval_id重试accept_agreement/handoff。
不要绕过 approval;不要未经用户确认自动 kiwi_approve;Kiwi 不处理支付
(payment 恒 NEVER)。
错误处理
task_not_found / task_expired:重查或重新询价。contract_violation:修正 intent 后重试。merchant_inquiry_unavailable:该商家仅有第 0 版公开资料、未开通实时询价;merchant_offline:该商家开通过实时询价,但服务当前离线(未在有效期内上报心跳)—— 公开资料仍可查,可稍后重试,不要表述成「从未开通」; 不可重试 RFQ,改为展示其公开资料与店铺入口。authorization_denied / approval_denied:硬拒绝,不可重试。partial_success:保留成功报价,失败项单独重试。- 交接前验证 checkout URL:
kiwi_handoff链接可能 404(演示商家 checkout 未实现),curl -sS -o /dev/null -w "%{http_code}" <url>验证,404 时如实告知用户。
演示
mcp__kiwi__kiwi_search("USB-C 扩展坞") → kiwi_request_quotes → kiwi_get_task
等报价 → 选候选 kiwi_negotiate 还价 → 用户确认后 kiwi_accept_agreement →
kiwi_get_agreement 审计 → kiwi_handoff。
