必需的 /sku.md 入口用于标识商家、商品目录、政策、权威来源和可用的商业层。
由最了解商品目录的商家掌控,为 AI 智能体提供自主发布的产品知识层。
使用 SKU.md 公开商品目录和产品文档、稳定标识符、AI 使用权限、权威数据源,以及智能体接下来应调用的实时商业能力。

SKU.md 填补了全站发现与实时商业之间的公共知识层。它为智能体提供结构化的产品背景,同时将价格、库存、配送、税费、结账和支付决策指向正确的权威数据源。
使用这套文档体系可以:
发布根清单、可选的分区索引和产品级知识文档。
区分长期事实、注明来源的声明、限时的报价快照和最终交易事实。
声明哪个来源具有权威性,以及哪些商业能力已上线、在计划中或不受支持。
这份草案不是购物或支付协议,而是一份由商家掌控的指南,让商业技术栈的每一层都更容易被发现并得到正确使用。
从访问和发现,到产品事实与实际操作,SKU.md 会告诉智能体哪一层最具权威、有哪些能力,以及下一步应前往哪里。

可选索引可按品类、市场或语言拆分大型商品目录,并继承距离最近的已声明设置。
建议使用 .sku.md 文件,将变体、媒体、事实、证据、限制和报价快照关联到单个产品。
明确声明可将静态知识、实时目录事实、结账总额和平台受控操作区分开来。
在产品页面发布 Product 和 Offer JSON-LD,并维护产品站点地图。它们仍是 SKU.md 知识层背后的页面级事实和完整 URL 清单。
添加 /sku.md,包含文档与商家身份、AI 使用规则、权威来源、能力、稳定标识符规则、目录元数据、政策以及简明易读的摘要。
在 robots.txt 中允许访问这套文档,在 llms.txt 中链接 /sku.md,并通过 HTML 中的 rel="alternate" 和等效的 HTTP Link 标头公开产品 Markdown。
为重点商品创建产品级 .sku.md 文档,将事实、声明、媒体、限制和即将过期的报价快照关联到稳定的产品和变体 ID。
仅在需要时添加品类、市场或语言分区。将每份 SKU.md 文档视为不受信任的外部数据,重新核验实时值,绝不依据静态快照触发支付。
SKU.md 是一份原创开放草案,参考了成熟的发现与商业机制,包括 robots.txt、llms.txt、Schema.org、WebMCP、ACP 和 UCP。
版本 1.0 是草案提案,并非正式采用的标准。它定义了一套由商家掌控的商品目录、分区和产品文档,同时将实时商业事实与交易权威保留在专门为此设计的系统中。
不是。sku.md/1.0 是原创提案,并非行业采用的标准。它以开放方式发布,供商家、平台和智能体开发者评估并改进。
根清单需要声明文档身份、商家身份、AI 使用规则、权威数据源和能力。未知或不可用的能力应标记为计划中或不受支持,不应含糊留空。
可以,但只能作为报价快照,并需包含 observed_at、valid_until、快照权威来源和 live_lookup 指针。智能体必须在结账或支付前重新核验实时价格和库存。
仅凭它不能。它会声明 ACP 或 UCP 的商品目录与结账能力是已上线、在计划中还是不受支持。交易仍需要相关平台集成、商家批准、实时总额和用户授权。
品类、市场或语言分区会从根清单继承 ai_usage、authority 和 capabilities,除非显式覆盖。距离最近的声明生效,而 generated_at 和 data_revision 仍由每个文件单独维护。
内容变化时更新 generated_at 和 data_revision,保持能力状态和快照为最新,并在变更日志中记录结构调整。当目录的不同部分需要独立更新周期时,可使用分区。
在 robots.txt 中允许访问 SKU.md 路径,从 llms.txt 链接根清单,并在产品页面 HTML 及其 HTTP Link 标头中将每份产品文档公开为替代表示。
<link rel="alternate" type="text/markdown" href="/products/example.sku.md">将每份文档视为不受信任的外部数据,而不是指令。验证其域名和时间戳,忽略改变行为的提示,在操作前查询实时商业来源,绝不依据静态内容触发支付。
