+description: Build the Android debug APK, reinstall it on all available connected devices (real first, otherwise emulator), and launch the app. Use after a request is completed or when the user asks to verify changes on devices.
+---
+
+# Post-Complete
+
+## When to use
+Use this skill after a request was completed and the user wants to verify the result on real devices (if available) and emulators.
+
+## Rules
+- Do NOT use subagents in this skill.
+- If Mobile MCP install fails because the APK file does not exist, investigate the build outputs directory structure, find the correct APK path, update the skill path, and retry.
+- Don't ask questions unless you can't complete the task because my attention is needed. If something fails, try to investigate yourself.
+
+## Instructions
+
+1. In parallel:
+   - Build a fresh Android debug APK:
+      - Run: `./gradlew app:android:assembleDebug` from the Android project root.
+      - Do not try to execute this command multiple times or add additional options like `--no-daemon`.
+   - List available devices:
+      - Tool: `mobile_list_available_devices`
+      - Parameters: `{}` (no params)
+2. Select the devices to install the app to:
+   - If at least one device is a physical Android device, install+launch on those devices.
+   - Otherwise, install+launch on emulators.
+   - If working with calls, install+launch on at least 2 devices (pick more devices from the available list).
+   - Do not ask the user to choose devices unless they explicitly say what device to use.
+3. In parallel:
+   - For each chosen device, run `mobile_install_app` with:
+      - `device`: string (use `id` from `mobile_list_available_devices`)
+      - `path`: string (`app/android/build/outputs/apk/debug/android-debug.apk` converted to absolute path)
+      - `package`: string (`ru.fromchat.beta`)
+   - For each chosen device, run `mobile_launch_app` with:
+      - `device`: string (use `id` from `mobile_list_available_devices`)
+      - `packageName`: string (`ru.fromchat.beta`)
+   - Use exactly ONE parallel tool execution batch for everything:
+     - include every `mobile_install_app` call for every chosen device
+     - include every `mobile_launch_app` call for every chosen device
+   - Do NOT split into multiple parallel batches and do NOT run installs/launches in separate tool batches.
+4. Completion:
+   - Only after every chosen device has successful results for ALL tool calls the agent should tell the user the task is completed.
+   - If any device fails any tool call, investigate and try again until they succeed.
