+# Backgammon AI Move Prompt
+
+Use this prompt template to ask an AI model for a valid backgammon move suggestion given a board state and dice roll.
+
+---
+
+## Prompt Template
+
+```
+We are playing backgammon. You are playing as {{color}} ({{color}} moves in the {{direction}} direction, from point {{start}} toward point {{end}} and then bearing off).
+
+### Board Configuration
+
+The board has 24 points numbered 1–24. Positive values represent {{positiveColor}} pieces; negative values represent {{negativeColor}} pieces. Zero means the point is empty.
+
+Board (point 1 to 24):
+{{board}}
+
+Pieces in prison (hit and waiting to re-enter):
+- White: {{prison.white}}
+- Black: {{prison.black}}
+
+Pieces already borne off (home):
+- White: {{home.white}}
+- Black: {{home.black}}
+
+### Dice
+
+You rolled: {{dice[0]}} and {{dice[1]}}
+{{#doubles}}(Doubles! You have four moves of {{dice[0]}} to use.){{/doubles}}
+
+### Your Task
+
+Choose the best legal play for this turn and respond **only** in standard backgammon notation. If no legal moves are available, respond with: `no move`
+```
