View source What is it?
Postiz is a social media scheduler for X, LinkedIn, Instagram, TikTok, YouTube, Facebook, Reddit, Pinterest and more than 20 others. This skill lets Claude use it: write and schedule posts, upload images and video, manage your connected accounts and pull analytics.
That means you can plan a week of content in one conversation, with Claude writing each post to suit the platform and booking it into the calendar. It's in Anthropic's official plugin directory and its Knowledge Work directory.
You need a Postiz account. Cloud plans start at $29 a month with a 7-day free trial. Postiz is open source, so you can also run it on your own server for free if you're comfortable with that.
Install in Claude Code
In Claude Code run /plugin install postiz@claude-plugins-official, or Postiz's own route: /plugin marketplace add gitroomhq/postiz-agent, then /plugin install postiz@postiz-agent. The skill drives the Postiz command-line tool, so also run npm install -g postiz, then postiz auth:login (or set your POSTIZ_API_KEY).
