Attempt Number: 5
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
The robot should paint the tile directly beneath it since it is currently holding black paint and the goal requires tile_3-1 to be painted black. This aligns with the goal and adheres to the constraints.

New State Description:
- Robot1 is on tile_3-1 and holding the color black.- Tile_3-1 is now painted black and is no longer clear.- Tile_3-2 and tile_3-3 remain clear.- All tiles in rows 0, 1, and 2 remain clear.- Both white and black colors are still available for switching.

Action Chosen:
paint-down(robot1, tile_3-1, tile_3-1, black)
