X API

Publish to X without leaving OpenWriter. Author in plain markdown, compose in a pixel-accurate X UI, and post from the pad.

Posting

  • post_to_x publishes single tweets, linked threads, and long-form X articles
  • Articles support cover images and full long-form bodies
  • Content is authored as plain markdown and serialized to the X format on post

Compose mode

A tweet compose view that mirrors X’s real UI:

  • Reply and quote-tweet drafting
  • Thread builder with linked tweets
  • What you draft is what gets posted — no surprise reflow
  • X-Writer is the writing skill that shapes the content this plugin posts
  • Publish is the platform layer for queuing and scheduling posts across channels
