+# fullscreen_message Skill
+
+This skill lets you display a fullscreen message popup on the local machine, triggered from the command line (or by other agents/automations). Great for visual notifications, alerts, or simple messages—works outside of chat.
+
+## Usage
+
+```
+python3 fullscreen_message_skill.py --message "Your custom message!" --timeout 5
+```
+- `--message` (optional): The text to display (default: "Hello, Adolfo!")
+- `--timeout` (optional): Auto-dismiss after N seconds (default: wait for key or click)
+
+You can connect this to a heartbeat or automation to make sure you never miss an alert!
+
+---
+
+### To Expand
+- Color, font size, dynamic sizing
+- Interactive elements (buttons, input)
+- Multi-message queue
+- Two-way local interaction
