Postiz Extended

Postiz Extended extends your AI assistant with the ability to schedule and manage social media posts via Postiz API (self-hosted or cloud). Direct API integration — no n8n dependency. Supports X/Twitter, LinkedIn, Bluesky with platform-specific character limits. Includes deduplication, scheduling, media upload, and thread creation. WHAT IT CAN DO: - Schedule posts to 28+ channels (X, LinkedIn, Bluesky, Reddit, Instagram, Facebook, Threads, YouTube, TikTok, Pinterest, Mastodon, and more) - Multi-platform posting in a single API call with platform-adapted content - X/Twitter thread creation for longer content - Media upload (file and URL) - Find next available posting slot per channel - List, query, update, and delete scheduled posts - Deduplication workflow (check existing before posting) - Platform-specific character limits and content tone guidance - Post state management (QUEUE, PUBLISHED, ERROR, DRAFT) - Helper script for quick posting with auto-validation USE WHEN: scheduling social media posts, creating multi-platform content, managing a p. Rather than leaving your conversation to handle this manually, you can ask your Claude agent directly — and it will take care of the task end-to-end, using Postiz Extended as its underlying capability.

Postiz Extended works across Claude, Cursor, OpenClaw through the Model Context Protocol (MCP) — an open standard that lets AI clients share tools and skills without lock-in. Because MCP is platform-agnostic by design, you install Postiz Extended once and it becomes available across all your AI clients. Whether you're working in Claude for focused sessions or Cursor for integrated workflows, the skill behaves consistently.

Getting started with Postiz Extended takes about two minutes. Place the skill at `~/.claude/skills/postiz-ext/` (personal, all projects) or `.claude/skills/postiz-ext/` (project-specific), then restart your AI client. From that point, typing `/postiz-ext` in any conversation activates it, or the AI will use it on its own when it detects a relevant request.

Postiz Extended has been installed 1,404 times, making it one of the more actively used skills in the Marketing & Growth category. The install rate suggests it solves a real, recurring need rather than a niche edge case. Like all skills on DiscoverAISkills, it is free to install and use. The broader AI skills ecosystem continues to expand as developers contribute new capabilities across categories like developer tools, data analysis, writing, automation, and more.
