5EAS Simulator 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.

7The `simulator:*` commands are **experimental and hidden**, and need a recent eas-cli (≥ 20.3.0 as of writing) — which is why this skill runs everything via `npx --yes eas-cli@latest`. Flags and verbs may change; **the relevant subcommand's `--help` output is authoritative.**

9## When to use

11The frontmatter `description` carries the trigger phrases. In short: use this to get a user's app onto a **cloud** simulator and interact with it — especially from a Mac-less or cloud/sandbox agent. **Not** for local sims (`expo run:ios`, Xcode, Android Studio), store builds/signing (that's EAS Build), or physical devices. For the macOS case, see *Cloud vs local* next.
