Postiz turns Claude into a social-media operations layer over the Postiz API. Schedule a post to X, LinkedIn, Instagram, Threads, YouTube, TikTok, Bluesky, Reddit, Facebook, Discord, Slack, Mastodon, Telegram, Medium, Dev.to, WordPress, and 12+ other platforms, all from a single workflow. Multi-platform posts, posts with comments and per-comment media, platform-specific settings (Reddit subreddits, YouTube playlists, LinkedIn companies), draft and schedule states, and analytics rollups across both platform and post level.

It's built for the operator who's tired of opening eight tabs to publish the same content. Authentication is OAuth2 device flow or API key; credentials live in ~/.postiz/credentials.json. Once authenticated, Claude can discover integrations, fetch dynamic data (Reddit flairs, playlists), upload media, create posts, change status, and run analytics, all without manual UI work.

• →Publish to 28+ social and chat platforms from one workflow, X, LinkedIn, Instagram, Threads, YouTube, TikTok, Reddit, Slack, more.
• →Multi-platform posts with platform-specific settings (Reddit subreddit, YouTube playlist, LinkedIn company).
• →Schedule, draft, or publish immediately, and flip a draft to scheduled with one command.
• →Posts with comments and per-comment media for thread-style content.
• →Analytics at both platform and post level, with daily data points and percentage change.
• →Resolves orphaned posts via posts:missing + posts:connect when analytics returns missing references.

• •Scheduling a content calendar across multiple platforms without opening each UI.
• •Publishing a multi-platform post with per-platform tweaks (subreddit, playlist, etc.).
• •Queuing drafts during a writing session and promoting them to scheduled later.
• •Pulling weekly analytics across all your accounts in one query.
• •Automating publishing from a content pipeline (CMS, spreadsheet, agent workflow).
• •Reconnecting posts whose analytics returned missing references.

Without this skill, Claude either drafts content and hands you the copy or tries to log into each platform separately. Postiz reshapes the workflow into authenticate, discover, prepare, post, analyze, every step a Postiz CLI command. You stop tab-juggling and start treating social posting as another scriptable surface.
