Upload-Post/upload-post-skill ? reverse-engineered prompt

Build me a Claude Code skill for Upload Post that helps an AI agent publish content to social media through the Upload Post API.

I want it to make uploading simple, so the agent can post videos, photos, text, documents, and carousels where supported, and handle cross posting to multiple platforms in one go. It should also support scheduling posts for later, checking upload status, and pulling back basic analytics or upload history when needed.

Make it easy to set up with a clear README style guide for getting an API key, connecting accounts, and using the skill. Include practical examples the agent can follow for common tasks like uploading a video to Instagram and TikTok, posting photos to LinkedIn or X, and checking whether a post finished successfully.

If there are any current API details that may have changed, look them up online and keep the skill aligned with the latest docs.
