  • create_articleUse this when someone gives you a finished blog post, or a translation of one, to save in their blog.No findings

    Why it is in this group

    • The name "create_article" says "create": a word for a change.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Use this when someone gives you a finished blog post, or a translation of one, to save in their blog. Returns the new post's id, title, slug, language and published state; it stays a draft unless published is true. A translation is saved with the original's id as originalArticleId and its own locale. Not for writing a post with AI.

    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Use this when someone asks to start a new blog in Polyblog with a given name and languages. Returns the new blog's id, name, domain and languages; the name becomes the public <name>.polyblog.io subdomain, so a name already taken fails. Not for adding a post to an existing blog.

    Why it is in this group

    • The name "delete_article" says "delete": a word for removing or ending something.
    • The description says "permanently delete".
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Use this when someone asks to permanently delete a blog post in every language. Given the original post's id, that post and all its translations are deleted and their pages go offline; given a translation's own id, nothing is deleted although the result still says deleted. Returns the id. Not for unpublishing.

    Why it is in this group

    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Use this when someone asks you to write a new blog post on a topic or saved topic idea. Returns the draft's id, URL, title, word count and internal links (text only; published only with autoPublish). It uses paid AI and can take about a minute, and a call that times out can still save the draft. Not for saving your own text.

    Description, as the server wrote it

    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Use this when someone asks to mark a topic idea as used, dismiss it, or bring it back as new. Returns the idea with its new status and, when given, the article it produced; nothing else about the idea changes. Not for editing an idea's title or angle.
