About

SKU.md is an experimental community proposal for merchant-published catalogs and optional product details with sources. Its design draws on established mechanisms, including robots.txt, Sitemap, llms.txt, Product JSON-LD, Merchant Feed, WebMCP, MCP, ACP, and UCP.

SKU.md 1.0.0 is an experimental community proposal. Mainstream AI products have not committed to discovering or trusting it by default, and publishing it does not guarantee visibility, ranking, recommendation, citation, or conversion.
