smabdulmueid97/social-media-posting

A Claude Code skill that turns one idea, video, or announcement into platform-ready posts for YouTube, Instagram, Facebook, TikTok, Bilibili, LinkedIn, and X.
One source, seven versions — each with its own hook, length, and hashtags. Never the same text pasted everywhere.

## Rules
Drafts only — it never publishes anything itself. You post, or use the platform's scheduler.
Facts stay identical everywhere: same link, same price, same date.
