 Prerequisites depend on the target platform: Node.js 22+, Xcode for iOS/tvOS/macOS targets, Android SDK + ADB for Android, and macOS Accessibility permission for desktop automation. Web automation requires Node 24+. See [Installation](https://oss.callstack.com/agent-device/docs/installation) for platform setup.

-On a fresh machine (first iOS run), start with `agent-device doctor --platform ios`: it preflights the environment and warms the iOS runner build cache in the background so the first `open` is fast.

 Use this skill only to route into version-matched CLI help. Let the selected help topic provide exact command shapes, platform limits, and current workflow guidance; use `help workflow` as the full reference when a task-specific topic is too narrow.
 
 For precise location workflows, read the installed `settings` help before planning so coordinate support and platform limits come from the active CLI version.
