+# Linux GUI Control
+
+This skill provides tools and procedures for automating interactions with the Linux desktop environment.
+
+## Quick Start
+
+### 1. Identify Target Window
+Use `wmctrl` to find the exact name of the window you want to control.
+```bash
+wmctrl -l
+```
+
+### 2. Inspect UI Hierarchy
+For apps supporting accessibility (GNOME apps, Electron apps with `--force-renderer-accessibility`), use the inspection script to find button names without taking screenshots.
+```bash
+python3 scripts/inspect_ui.py "<app_name>"
+```
+
+### 3. Perform Actions
+Use `xdotool` via the helper script for common actions.
+```bash
+# Activate window
+./scripts/gui_action.sh activate "<window_name>"
+
+# Click coordinates
+./scripts/gui_action.sh click 500 500
+
+# Type text
+./scripts/gui_action.sh type "Hello World"
+
+# Press a key
+./scripts/gui_action.sh key "Return"
+```
+
+## Workflows
+
+### Operating an App via Text UI
+1. List windows with `wmctrl -l`.
+2. Activate the target window.
+3. Run `scripts/inspect_ui.py` to get the list of buttons and inputs.
+4. Use `xdotool key Tab` and `Return` to navigate, or `click` if coordinates are known.
+5. If text-based inspection fails, fallback to taking a screenshot and using vision.
+
+### Forcing Accessibility in Electron Apps
+Many modern apps (VS Code, Discord, Cider, Chrome) need a flag to expose their UI tree:
+```bash
+pkill <app>
+nohup <app> --force-renderer-accessibility > /dev/null 2>&1 &
+```
+
+## Tool Reference
+
+- **wmctrl**: Window management (list, activate, move, resize).
+- **xdotool**: Input simulation (click, type, key, mousemove).
+- **dogtail**: UI tree extraction via AT-SPI (Accessibility bus).
+- **scrot**: Lightweight screenshot tool.
