+# SKILL.md - Say Out Loud
+
+## Purpose
+Announce messages out loud through the Mac mini’s built-in speakers. Plays a chime, sets volume to 80%, and uses the macOS default system voice. Triggers on phrases like “talk to us” or “say out loud.”
+
+## Triggers
+- “talk to us”
+- “say out loud”
+- “announce”
+- or by explicit command in the interface
+
+## How it works
+- Sets output to built-in speakers (if available)
+- Sets volume to 80%
+- Plays the macOS "Glass" chime
+- Speaks the full answer using the system's default voice (can be changed to Alex, David, etc. on request)
+
+## Usage
+Just say “talk to us” or any of the trigger phrases and Bro will say the next message out loud for everyone in the room.
