expo — Agent Skill

Expo

Official AI agent skills from the Expo team for building, deploying, upgrading, and debugging Expo apps.

Skills come in two groups so the free vs paid boundary stays clear: open-source framework skills, and services & paid distribution skills whose core purpose uses paid Expo Application Services (EAS). Each services skill opens with a costs/plan-limits note.
