Run and control a user's app on a remote iOS/Android simulator with Expo Simulators (also called EAS Simulator). Read before running any `eas simulator:*` commands - it has the current syntax and workflow. Use whenever the user needs a simulator they can't run locally - 'run my app on a cloud simulator', 'use eas simulator to run/install/screenshot my app', 'I'm on Linux/Cursor and need an iOS device', 'no sim on this box / headless CI', 'let an agent click through my app and screenshot it', 't…

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'eas-simulator' ] || [ -L ~/.agents/skills/'eas-simulator' ]; then echo 'A skill folder named eas-simulator already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/expo/skills' "$d" && git -C "$d" checkout --quiet '7582922d039d5a96dc574757d399d22d56370f2b' -- 'plugins/expo/skills/eas-simulator' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/expo/skills/eas-simulator' ~/.agents/skills/'eas-simulator' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'eas-simulator' ~/.claude/skills/'eas-simulator' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
