Take a screenshot of the booted iOS simulator and display it.
Capture the screenshot from the booted iOS simulator:
xcrun simctl io booted screenshot /tmp/ios-screenshot-full.png
Resize to 800px max dimension for token efficiency (reduces ~90% of tokens vs full 2556px resolution while staying legible):
sips -Z 800 /tmp/ios-screenshot-full.png --out /tmp/ios-screenshot.png
Use the Read tool to display /tmp/ios-screenshot.png to the user.
Clean up the full-size temporary file:
rm /tmp/ios-screenshot-full.png
xcrun simctl io booted screenshot fails, tell the user no iOS simulator is currently booted and suggest they launch one (e.g. via Xcode or xcrun simctl boot "iPhone 17 Pro").sips fails, fall back to displaying the full-size screenshot directly.
