UserAgent skills for visually testing mobile apps on Android — run a Flutter, React Native, or native Android app on an emulator/device, capture real screenshots via adb, read logs, optionally diff against a Figma design, and verify the UI rendered correctly. Works with Claude Code and other coding agents.

flutter-test-android-visually
Run a Flutter app on a connected Android device or emulator, capture real screenshots via adb, read the Dart + logcat logs, and verify the visible UI and runtime behavior match what a recent code change intended. Use whenever the user asks to "test the app", "run it on Android", "see the visual changes", "verify a UI fix", "check if my change works/renders", or otherwise wants empirical on-device confirmation that a Flutter change rendered correctly — even when they don't say "screenshot" or "logs". Handles launching with the right entry point and flags, waiting for the first real frame, navigating with adb input, capturing the screen, reading flutter + logcat output, and reporting a concrete verdict with evidence. Optionally diffs against a Figma reference when one is provided. Android only (iOS needs a Mac).
react-native-test-android-visually
Run a React Native or Expo app on a connected Android device or emulator, capture real screenshots via adb, read the Metro + logcat logs, and verify the visible UI and runtime behavior match what a recent code change intended. Use whenever the user asks to "test the app", "run it on Android", "see the visual changes", "verify a UI fix", "check if my change works/renders", or otherwise wants empirical on-device confirmation that a React Native / Expo change rendered correctly — even when they don't say "screenshot" or "logs". Handles starting Metro and the native build, waiting for the bundle + first frame, navigating with adb input, capturing the screen, reading Metro/logcat output (ReactNative / ReactNativeJS, Hermes, red-box errors), and reporting a concrete verdict with evidence. Covers bare React Native and Expo (dev client + run:android). Optionally diffs against a Figma reference when one is provided. Android only (iOS needs a Mac).
native-android-test-visually
Build, install, and run a native Android app (Kotlin or Java, Jetpack Compose or Views, Gradle) on a connected device or emulator, capture real screenshots via adb, read logcat, and verify the visible UI and runtime behavior match what a recent code change intended. Use whenever the user asks to "test the app", "run it on the emulator", "see the visual changes", "verify a UI fix", "check if my change works/renders", or otherwise wants empirical on-device confirmation that a native Android change rendered correctly — even when they don't say "screenshot" or "logs". Handles the Gradle install task (and build variants/flavors), launching the activity, waiting for the first frame, navigating with adb input, capturing the screen, reading logcat scoped to the app, and reporting a concrete verdict with evidence. Optionally diffs against a Figma reference when one is provided.
