Docusaurus: what an agent reads

In short

Docusaurus does not ship llms.txt in core. Docusaurus totals 7 of 16 on the eight numeric keys, from a test build of Docusaurus 3.10.2. It also does not negotiate markdown on its own, since output is static files. Docusaurus: Docusaurus is a static site generator and generates HTML files for every possible path at build time.

Docusaurus Framework, Meta Open Source

Open-source static site generator for docs: HTML for every route at build time, with llms.txt only through community plugins.

Work left to the developer: Medium: write or install an llms.txt plugin, link it in the footer, and add the host rule for Accept; the 404 page is already built.

The nine scores

Key	Score	Evidence	Source
Content in the initial HTML	2, on by default	Test build, Docusaurus 3.10.2, 2026-11-04: the classic template prerendered the home page with an H1 and the docs pages with their text.	docusaurus.io/docs/advanced/ssg, 2026-11-04
Real status codes	2, on by default	Test build: build/ held 404.html and docusaurus serve answered a made-up path with 404 directly.	docusaurus.io/docs/advanced/ssg, 2026-11-04
llms.txt generation	0, not offered	Test build: no llms.txt or robots.txt in build/ (sitemap.xml was written). Docusaurus has no first-party llms.txt feature; community plugins exist and none was installed.	docusaurus.io/docs/seo, 2026-11-04
llms.txt linking	0, not offered	Test build: nothing links an llms.txt and none exists.	docusaurus.io/docs/seo, 2026-11-04
Markdown on request	0, not offered	Test build: Accept: text/markdown on / returned text/html and /index.md returned 404. The output is static files, so negotiation has to live in the host or an edge rule, the same need Astro has.	docusaurus.io/docs/advanced/ssg, 2026-11-04
JSON-LD output	1, with setup	Test build: no JSON-LD emitted. A script element can be added through the config head tags.	docusaurus.io/docs/seo, 2026-11-04
OpenAPI exposure	0, not offered	Test build: no OpenAPI file or link; Docusaurus has no first-party feature for one.	docusaurus.io/docs/advanced/ssg, 2026-11-04
Fenced, tagged code	2, on by default	Test build: a fence in a docs page became a pre element with a language class (language-md) from Prism, with no setup.	docusaurus.io/docs/markdown-features/code-blocks, 2026-11-04
Work left to the developer		Medium: write or install an llms.txt plugin, link it in the footer, and add the host rule for Accept; the 404 page is already built. Based on the test build above and the documentation pages cited for each key.	docusaurus.io/docs/seo, 2026-11-04

Test build

Docusaurus 3.10.2, built on 4 November 2026. create-docusaurus classic template in TypeScript, npm run build, docusaurus serve. What it emitted:

A made-up path returned 404 directly from docusaurus serve.
Accept: text/markdown on / returned text/html; /index.md returned 404.
Fenced code became pre with a language-md style class from Prism.
No JSON-LD and no link rel alternate markdown.

Scoring rules for every key are on the method page.
