Read 2026-11-05. Source: https://agentreadyhtml.com/vendors/ghost/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # Ghost: vendor profile In short Ghost added llms.txt and markdown copies on 2026-07-16, off by default for sites that existed before. Ghost(Pro) sites got the feature at once, and a self-hosted install had to update first. Paid and members-only posts stay out of both files apart from a title and excerpt, and private sites serve neither. ## At a glance **standards.txt** ghost ```text llms-txt = supports markdown-negotiation = no statement markdown-twin = supports initial-html = no statement real-404 = no statement vary-accept = no statement ``` 2 supports, 0 partial or announced, 4 no statement. **Ghost** Content management system Open-source publishing platform for blogs and newsletters. Since July 2026 Ghost can write /llms.txt and serve a markdown copy of each public post at its URL plus .md, switched on under Settings, Meta data.
