x-player-card

A Claude Code skill that puts a live mini website inside a tweet: a signup form, search box, calculator or game that people use without leaving the X timeline.

It uses X's player card (twitter:card=player). The skill covers the meta tags, the frame-ancestors header, building for X's sandboxed iframe, the poster image, mobile, bot firewalls that block Twitterbot, and a check list to run before you post.

Install

git clone https://github.com/rdoyle99/x-player-card ~/.claude/skills/x-player-card

Then in Claude Code: "put a newsletter signup inside a tweet for my site".

Live examples

• https://www.rpdoyle.com/x (email signup, Next.js)
• https://www.tmaker.io/subscribe (the card that started it, by @tibo_maker)
