+name: mobilecli
+description: Run mobile automation, app testing, and interact with iOS and Android devices, simulators, emulators, and apps using the mobilecli CLI tool or JSON-RPC API. Trigger this skill whenever the user wants to list connected devices, boot or shut down simulators/emulators, take mobile screenshots, start screen recordings, send key/touch inputs (tap, text, swipe, hardware buttons), manage apps (install, uninstall, launch, terminate, get foreground app), inspect webviews (query DOM, evaluate JS, navigate), download/upload files on-device, or get crash reports, even if they don't explicitly name "mobilecli".

+# Mobile CLI
+
+A universal automation and management skill for iOS and Android devices, simulators, emulators, and mobile apps. This skill guides you through interacting with devices, automating applications, performing gestures, capturing screen states, inspecting webviews, and interacting with the `mobilecli` command-line interface and background JSON-RPC server.

+
+## 🛠 Prerequisites & Server Setup
+
+Before using this skill, ensure the environment has the necessary prerequisites installed and configured:
+
+- **Android SDK**: `adb` must be available in the system `PATH`.
+- **Xcode Command Line Tools**: Required for iOS Simulator control (on macOS).
+- **On-Device Agent**: Required for iOS input gestures, screenshots, and UI dumping, and for Android non-ASCII text input.
+
+### Run instantly with npx
+If `mobilecli` is not installed globally, you can invoke any command using `npx`:
+```bash
+npx mobilecli@latest <command>
+```
+
+### Starting and Stopping the JSON-RPC Daemon (Recommended)
+Starting the HTTP server is highly recommended for automated scripts and fast interactions. It caches device information, keeps connections/tunnels alive, and eliminates command-line startup overhead.
+
+```bash
+# Start server in the foreground (defaults to localhost:12000)
+mobilecli server start --listen localhost:12000 --cors
+
+# Start server in the background (daemon mode)
+mobilecli server start --listen localhost:12000 --cors --daemon
+
+# Stop a background daemon server
+mobilecli server kill --listen localhost:12000
+```
+
+---
+
+## 🔄 AI Automation Workflows
+
+When executing mobile automation or app testing, follow this structured loop:
+
+```mermaid
+graph TD
+    A[List Devices & Select Target] --> B[Launch Target Application]
+    B --> C[Inspect State: UI Tree / Screenshot]
+    C --> D{Is Goal Achieved?}
+    D -- No --> E[Find Target Element Coordinates]
+    E --> F[Perform Gesture: Tap/Swipe/Text]
+    F --> C
+    D -- Yes --> G[Finish Automation / Report Results]
+    C -- Error/Crash --> H[Pull Crash Log / Restart App]
+    H --> C
+```
+
+1. **Find & Target Device**: Run `mobilecli devices` to see online devices and simulators. If only one device is online, it is automatically selected; otherwise, pass the device ID to the `--device <id>` flag.
+2. **Launch App**: Use `mobilecli apps launch <bundle-id>` to bring the target application to the foreground.
+3. **Capture State**:
+   - Dump the UI tree: `mobilecli dump ui` to locate elements programmatically.
+   - Take a screenshot: `mobilecli screenshot` to visually confirm what is displayed.
+4. **Interact**: Locate your target element in the UI dump, calculate its center coordinates, and trigger inputs (e.g. `mobilecli io tap`, `mobilecli io text`).
+5. **Repeat or Debug**: Verify the changes in a new UI dump or screenshot, handle popups, and check crash reports if the app terminates.
+
+---
+
+## 💻 Command Reference (CLI)
+
+All commands support the global `--device <id>` flag to specify the target device, and `-v` / `--verbose` for logging.

+
+## 🔌 JSON-RPC Server & WebSocket API
+
+For scripts and long-running automation, make HTTP POST requests to the server's endpoint (`http://localhost:12000/rpc`). The JSON-RPC payload format is:
+`{"jsonrpc": "2.0", "method": "<method_name>", "params": { ... }, "id": 1}`
+
+### Core JSON-RPC API Examples
+
+* **List Devices**:
+  ```bash
+  curl http://localhost:12000/rpc -X POST -H "Content-Type: application/json" \
+    -d '{"jsonrpc":"2.0", "id": 1, "method": "devices.list", "params": {}}'
+  ```
+* **Take Crop/Clip Screenshot**:
+  ```bash
+  curl http://localhost:12000/rpc -X POST -H "Content-Type: application/json" \
+    -d '{"jsonrpc":"2.0", "id": 2, "method": "device.screenshot", "params": {"deviceId": "device-id", "format": "png", "clip": {"x": 50, "y": 100, "width": 200, "height": 300}}}'
+  ```
+* **Stop Server Remotely**:
+  ```bash
+  curl http://localhost:12000/rpc -X POST -H "Content-Type: application/json" \
+    -d '{"jsonrpc":"2.0", "id": 3, "method": "server.shutdown", "params": {}}'
+  ```
+
+### Custom Gestures (JSON-RPC only)
+For complex multi-action interactions (e.g. dragging, pinching, or specific curves) which are not accessible via standard CLI gestures, use the `device.io.gesture` method. This allows you to chain raw pointer motion events.
+
+Supported actions:
+- `pointerDown`: Touches screen at the current x,y coordinate.
+- `pointerMove`: Moves coordinates to target `x`, `y`.
+- `pointerUp`: Lifts pointer off screen.
+- `pause`: Sleeps for `duration` (in milliseconds).
+
+**Example: Drag-and-Drop Action**
+```json
+{
+  "jsonrpc": "2.0",
+  "id": 1,
+  "method": "device.io.gesture",
+  "params": {
+    "deviceId": "my-device-id",
+    "actions": [
+      { "type": "pointerMove", "x": 100, "y": 150 },
+      { "type": "pointerDown" },
+      { "type": "pause", "duration": 500 },
+      { "type": "pointerMove", "x": 300, "y": 450 },
+      { "type": "pause", "duration": 200 },
+      { "type": "pointerUp" }
+    ]
+  }
+}
+```
+
+### Filesystem Limits in JSON-RPC
+> [!WARNING]
+> **1MB RPC payload limit**: The JSON-RPC calls `device.fs.push` and `device.fs.pull` encode file data using Base64. To maintain server performance, the maximum file size supported by these RPC endpoints is **1 MB**.
+> 
+> If you need to transfer databases, video files, or payloads larger than 1 MB, you must bypass the JSON-RPC endpoints and invoke the CLI commands directly (`mobilecli fs push` / `mobilecli fs pull`), which handle raw streams and are binary-safe for large volumes.
+
+### WebSocket API
+You can open a persistent connection to `ws://localhost:12000/ws` using tools like `wscat`:
+```bash
+wscat -c ws://localhost:12000/ws
+> {"jsonrpc":"2.0","id":1,"method":"devices.list","params":{}}
+< {"jsonrpc":"2.0","id":1,"result":[...]}
+```
+
+---
+
+## 🍎 Platform-Specific Notes & Troubleshooting
+
+### iOS Real Devices
+- **Agent Dependency**: Input gestures, screenshots, and UI dumps require the agent. Install it via:
+  ```bash
+  mobilecli agent install --device <device-id> --provisioning-profile /path/to/profile.mobileprovision
+  ```
+  A valid Apple Provisioning Profile and signing identity must be present on the host to code-sign the agent.
+
+### Android Real Devices & Emulators
+- **ADB Access**: Ensure the device has "USB Debugging" enabled.
+- **App Private Container Paths**: Android app containers (`/data/user/0/...`) are accessed using `run-as`, which requires the application to be built as **debuggable** (`android:debuggable="true"` in the manifest).
+
+### iOS Simulator
+- Crash logs are read directly from `~/Library/Logs/DiagnosticReports/`.

+
+## 💡 Best Practices for AI Agents
+
+> [!TIP]
+> **Use the JSON-RPC server whenever possible**: Invoking `mobilecli` via subprocess CLI commands incurs Go binary startup latency each time. Starting the server and querying it over HTTP/WebSocket speeds up interactions from seconds to milliseconds.
+
+> [!IMPORTANT]
+> **Tap coordinates must target the center of the bounding box**:
+> When parsing a UI element from `mobilecli dump ui`, locate the element's `rect` (`x`, `y`, `width`, `height`). Calculate the center coordinates:
+> $$\text{Center X} = x + \frac{\text{width}}{2}$$
+> $$\text{Center Y} = y + \frac{\text{height}}{2}$$
+> Send this center point to `mobilecli io tap --device <device-id> <CenterX>,<CenterY>`.
+
+> [!NOTE]
+> **Interact with input fields before writing text**:
+> To write text into a text field, first trigger a tap on the center of that text field to focus it, wait a few hundred milliseconds for the soft keyboard to appear, and then call `mobilecli io text`.
+
+> [!WARNING]
+> **Auto-selection caveat**:
+> While `mobilecli` auto-selects the target device when only *one* online device is connected, always verify the list of connected devices first. If multiple devices are online, you must pass the exact device ID to avoid command failures.
