Agent Content Negotiation

1 post · Feb 2026

What this trail covers

Vercel has implemented content negotiation to serve agent-friendly markdown versions of pages, significantly reducing payload size and improving agent efficiency. This includes updating pages like the blog and changelog, and generating markdown sitemaps for agent discovery. The implementation in Next.js involves rewrite rules and route handlers to serve markdown, and the use of `link rel="alternate"` tags for fallback discovery.

  1. Making agent-friendly pages with content negotiationThis post details the implementation of content negotiation in Next.js to serve markdown versions of web pages to agents. It includes a `next.config.ts` rewrite rule to detect the `Accept: text/markdown` header and a route handler (`app/blog/md/[...slug]/route.ts`) to convert CMS rich text to markdown on the fly. It also introduces markdown sitemaps for agent discovery, with examples for blog posts (`app/blog/sitemap.md/route.ts`) and hierarchical documentation (`app/docs/sitemap.md/route.ts`). The post highlights the significant performance benefits (99.37% payload reduction) and mentions the use of Next.js 16 remote cache for synchronization.
