It allows for autonomous interaction, state verification, and visual regression checking.</p>\n<h2>When to Use</h2>\n<ul>\n<li>Verifying UI changes in React Native or Native Android apps.</li>\n<li>Autonomous debugging of layout issues or interaction bugs.</li>\n<li>Ensuring feature functionality when manual testing is too slow.</li>\n<li>Capturing automated screenshots for PR documentation.</li>\n</ul>\n<h2>\uD83D\uDEE0 Prerequisites</h2>\n<ul>\n<li>Android Emulator running.</li>\n<li><code>adb</code> installed and in PATH.</li>\n<li>Application in debug mode for logcat access.</li>\n</ul>\n<h2>\uD83D\uDE80 Workflow</h2>\n<h3>1. Device Calibration</h3>\n<p>Before interacting, always verify the screen resolution to ensure tap coordinates are accurate.</p>\n<pre><code>adb shell wm size\n</code></pre>\n<p><em>Note: Layouts are often scaled. Use the physical size returned as the base for coordinate calculations.</em></p>\n<h3>2. UI Inspection (State Discovery)</h3>\n<p>Use the <code>uiautomator</code> dump to find the exact bounds of UI elements (buttons, inputs).</p>\n<pre><code>adb shell uiautomator dump /sdcard/view.xml &amp;&amp; adb pull /sdcard/view.xml ./artifacts/view.xml\n</code></pre>\n<p>Search the <code>view.xml</code> for <code>text</code>, <code>content-desc</code>, or <code>resource-id</code>. The <code>bounds</code> attribute <code>[x1,y1][x2,y2]</code> defines the clickable area.</p>\n<h3>3. Interaction Commands</h3>\n<ul>\n<li><strong>Tap</strong>: <code>adb shell input tap &lt;x&gt; &lt;y&gt;</code> (Use the center of the element bounds).</li>\n<li><strong>Swipe</strong>: <code>adb shell input swipe &lt;x1&gt; &lt;y1&gt; &lt;x2&gt; &lt;y2&gt; &lt;duration_ms&gt;</code> (Used for scrolling).</li>\n<li><strong>Text Input</strong>: <code>adb shell input text \"&lt;message&gt;\"</code> (Note: Limited support for special characters).</li>\n<li><strong>Key Events</strong>: <code>adb shell input keyevent &lt;code_id&gt;</code> (e.g., 66 for Enter).</li>\n</ul>\n<h3>4. Verification &amp; Reporting</h3>\n<h4>Visual Verification</h4>\n<p>Capture a screenshot after interaction to confirm UI changes.</p>\n<pre><code>adb shell screencap -p /sdcard/screen.png &amp;&amp; adb pull /sdcard/screen.png ./artifacts/test_result.png\n</code></pre>\n<h4>Analytical Verification</h4>\n<p>Monitor the JS console logs in real-time to detect errors or log successes.</p>\n<pre><code>adb logcat -d | grep \"ReactNativeJS\" | tail -n 20\n</code></pre>\n<h4>Cleanup</h4>\n<p>Always store generated files in the <code>artifacts/</code> folder to satisfy project organization rules.</p>\n<h2>\uD83D\uDCA1 Best Practices</h2>\n<ul>\n<li><strong>Wait for Animations</strong>: Always add a short sleep (e.g., 1-2s) between interaction and verification.</li>\n<li><strong>Center Taps</strong>: Calculate the arithmetic mean of <code>[x1,y1][x2,y2]</code> for the most reliable tap target.</li>\n<li><strong>Log Markers</strong>: Use distinct log messages in the code (e.g., <code>✅ Action Successful</code>) to make <code>grep</code> verification easy.</li>\n<li><strong>Fail Fast</strong>: If a <code>uiautomator dump</code> fails or doesn't find the expected text, stop and troubleshoot rather than blind-tapping.</li>\n</ul>\n<h2>Limitations</h2>\n<ul>\n<li>Use this skill only when the task clearly matches the scope described above.</li>\n<li>Do not treat the output as a substitute for environment-specific validation, testing, or expert review.</li>\n<li>Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.</li>\n</ul>\n","files":[{"path":"scripts/verify_ui.sh","sizeBytes":895,"isText":true},{"path":"SKILL.md","sizeBytes":3164,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
