Markdown for Agents Checker

HTML is useful for browsers but noisy for assistants. Markdown negotiation gives agents a smaller, quote-ready representation of the same public content.

Answer first

What it checks

The scan requests the canonical page with Accept: text/markdown, checks the content type, verifies Vary: Accept, and compares the response with HTML signals.

Detail 01

When it helps

Docs, guides, methodology pages, and fix pages benefit most because assistants need stable text, headings, links, and code snippets.

Detail 02

Cache correctly

Serve explicit markdown only when requested, set Vary: Accept, and avoid letting CDN caches mix HTML and markdown under the same key.

FAQ

Common questions

Does every page need a markdown variant?
No. Start with docs, guides, methodology, and fix pages where textual extraction quality matters most.
Can I use text/* or */* to trigger markdown?
No. Browsers often send wildcards. Serve markdown only when text/markdown is explicitly preferred.
