What it does

Evaluate Expo skills in this repo end-to-end - trigger accuracy, generated code quality, and runtime screenshots on iOS simulator and Android emulator via Expo Go (web optional). Use when the user wants to eval an Expo skill, test that a skill produces working code, benchmark a skill with device screenshots, or verify a skill's output renders correctly.

Install

With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:

npx skills add expo/skills --skill expo-skill-eval

Or copy the skill folder into Claude Code's skills directory by hand (~/.claude/skills for every project, or .claude/skills inside one):

git clone --depth 1 https://github.com/expo/skills
cp -r skills/.claude/skills/expo-skill-eval ~/.claude/skills/expo-skill-eval
