Parent State ID: 13
State Depth: 4
Action Taken: move_square(square0, f0-0f, f0-1f)
Action Reasoning: Moving "square0" from f0-0f to f0-1f clears f0-0f, making progress toward clearing the top three rows.
State Description: - **rightl0 (L-shaped piece)**: Occupies positions f3-0f, f4-0f, and f4-1f; unchanged.- **straight0 (Two-square straight piece)**: Occupies positions f1-0f and f2-0f; unchanged.- **straight1 (Two-square straight piece)**: Occupies positions f0-2f and f1-2f; unchanged.- **straight2 (Two-square straight piece)**: Occupies positions f1-1f and f2-1f; unchanged.- **square0 (One-square piece)**: Now occupies position f0-1f, previously at f0-0f.- **square1 (One-square piece)**: Remains in position f2-2f; unchanged.- **Grid Cells (Unoccupied)**: Positions f5-0f to f5-3f, f4-2f to f4-3f, f3-2f to f3-3f, f0-0f, f2-3f, f1-3f, f0-3f are clear.
Action Path: ['move_l_down(rightl0, f2-0f, f3-0f, f3-1f, f4-0f, f4-1f)', 'move_two(straight0, f0-0f, f1-0f, f2-0f)', 'move_square(square0, f0-1f, f0-0f)', 'move_square(square0, f0-0f, f0-1f)']

successfully verified the action of new state 18 with the path: The last action `move_square(square0, f0-0f, f0-1f)` is valid because all preconditions are satisfied: f0-1f is clear, square0 occupies f0-0f, and f0-0f and f0-1f are adjacent. The effects are correctly updated in the current state's description and visualization. The action does not directly achieve the goal but is a valid step in the process. The current state's natural language description and visualization are accurate and consistent with the actions taken.
