Eas Simulator
This gets your Expo app running on a real iOS or Android simulator in the EAS cloud when you can't run one locally. The obvious case is Linux boxes or headless CI where there's no Xcode, but it's also the unlock for letting an AI agent actually click through your app and screenshot it instead of just guessing at code. It's experimental API territory (the commands are hidden and the flags shift), costs money per session, and the skill wraps everything in `npx eas-cli@latest` to guarantee a new enough CLI. The workflow is always start, install your app, drive it with agent-device through `simulator:exec`, then stop. On macOS it asks first since you probably have a local sim and don't need the cloud tax.

Expo Simulators
EAS service - costs apply. Sessions count toward your account's pricing and limits and stop at their maximum duration. Stop a session with

Expo Simulators runs a remote iOS simulator or Android emulator on EAS infrastructure that you drive from your machine — from the CLI, from an AI agent (via agent-device), and from a browser preview. It's the unlock for environments that can't run a simulator locally (Linux boxes, cloud/background agents like Cursor Cloud), and for letting an agent verify a change on a real device instead of only reasoning about code.
Naming. The service is called Expo Simulators. "EAS Simulator" is an internal name that is still in use, and the CLI commands are eas simulator:* (alias eas sim:*). All of these names mean the same service: treat a request that uses any of them as a request for this skill. When you talk to the user about the service, call it Expo Simulators. Keep the exact command names (eas simulator:start) in commands.
