App Preview Craft is an Agent Skill that generates App Store/Play Store screenshots, social cards, 3D device mockups, and promo videos from raw screenshots and recordings. It uses headless Chrome, three.js, and ffmpeg to render locally, offering 40+ themes, CLI and Studio UI, and multi-agent compatibility. It's interesting because it packages a complex asset pipeline into a single skill for AI coding agents, reducing manual design work.

Target audience: mobile app developers, indie hackers, product marketers
