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.Use when updating npm/yarn dependencies in shared/package.json. Use for routine dep bumps, security updates, or keeping packages current.
Use when refactoring Keybase Zustand stores in `shared/stores` to remove screen-local or route-owned state, keep only truly global or cross-screen data in the store, prefer querying the Go service layer over frontend convenience caches, move one-off RPC calls into components with `C.useRPC`, and split the work into safe stacked commits.
Use when writing, fixing, or adding e2e flow tests for the Keybase app — desktop (Playwright) or iOS (Maestro). Covers testID conventions, navigation patterns, common pitfalls, and the two-harness structure.
Migrate React Navigation navigators from dynamic component based config to static object based config.
