Use this skill to move files between host and device with `adb pull` and `adb push`, including the modern `-z` (compression), `-Z` (no compression), `--sync`, and `-a` (preserve attrs) flags. Covers the path-permission rules — `/data/local/tmp/` is freely…

Use this skill to verify a Compose semantics node's properties from a UI test using `assertExists`, `assertDoesNotExist`, `assertIsDisplayed`, `assertIsNotDisplayed`, `assertIsDeactivated`, `assertIsEnabled`, `assertIsOn`, `assertIsOff`, `assertIsSelected`,…
Use this skill to perform an end-to-end review of an existing Jetpack Compose UI test file or test suite. Sequences six audit phases (setup correctness, finder discipline, assertion strength, action correctness, time/idle correctness, debug output) and routes…
Use this skill to enable Espresso's `AccessibilityValidator` against the Compose semantics tree via `enableAccessibilityChecks(...)` from `androidx.compose.ui:ui-test-accessibility` (for `ComposeUiTest`) or `androidx.compose.ui:ui-test-junit4-accessibility`…
Use this skill to diagnose "no node matched", "found N nodes", and "useUnmergedTree" failures by dumping the actual semantics tree with `printToLog(tag, maxDepth)` and `printToString(maxDepth)`. Covers the output grammar (`Node
