# Jekyll

Jekyll builds every page to static HTML, which meets AR-READ-01, and GitHub Pages builds it natively. The jekyll-sitemap plugin writes sitemap.xml once enabled, and jekyll-seo-tag adds metadata tags. The docs read say nothing about llms.txt or robots rules, and static output cannot negotiate markdown by Accept.

## Checks on its own site

| Reading | Result | Date | Source |
| --- | --- | --- | --- |
| Cloudflare scan of jekyllrb.com | 7 of 100, band L0 Not Ready | 2026-11-05 | isitagentready.com |
| Home pages counted in the crawl | 3 of 5,897; Counted from the shared crawl of 2026-11-04 by generator meta tag in the home page HTML; the generator rule only sees tags whose name attribute comes first, so it undercounts | 2026-11-04 | agentreadychecklist.com/data/ |

## What it does not do

-   Jekyll does not produce llms.txt or markdown twins; it converts markdown to HTML and drops the source.
-   Jekyll on GitHub Pages cannot run plugins outside GitHub's supported list unless the site is built in a workflow.
