Use when the user says \"publish this\", \"put this online\", \"make this a website\", \"share this as a page\" or \"host this\".\n\nAccepts Markdown (.md, rendered as a styled page with navigation), HTML (.html, served as-is) and supporting files such as CSS, JS, JSON and images: one page or a small site, up to 50 files and 3 MB per call. Name the home page index.md or index.html.\n\nWithout an account this creates a new site that expires in 7 days and returns a claim link: always show the user the live URL and the claim link exactly as returned, so they can keep the site. To update that site later in the conversation, call publish again with its siteId and claimToken and only the files you changed or added: files you don't send are kept as they are. To remove pages or files, list their paths in delete (files can then be empty). Only when the user explicitly asks to start the site over, set replaceWholeSite to true: the files you send become the whole site and every other file is removed. If that would remove existing files, the call is refused and tells you how many and which; ask the user, then call again with confirmDeleteCount set to that number. For bigger sites, suggest the Flowershow CLI (fl).",
