The grid contains:\n- **Clue cells** with sum constraints for across and down segments\n- **Empty cells** to be filled with digits 1-9\n- **Constraints**: no repeated digits within a segment, all digits must sum to the clue value\n\n## Difficulty Levels\n\n| Size | Difficulty | Description |\n|------|-----------|-------------|\n| 3x3  | Easy      | Simple 2-3 cell segments |\n| 4x4  | Medium    | Multiple intersecting constraints |\n| 5x5  | Hard      | Complex multi-segment deductions |\n\n## Evaluation\n\nThree scoring dimensions:\n- **Accuracy** (70%): Correctness of the final solution\n- **Format** (15%): Proper answer format with all cells filled\n- **Reasoning** (15%): Quality of step-by-step solving approach\n\n## Usage\n\n```python\nimport verifiers as vf\n\nenv = vf.load_environment(\"rosi/kakuro-env\")\n```\n\n## Example Puzzle\n\n```\nACROSS: Row 0 sum=3, Row 1 sum=4\nDOWN: Col 0 sum=2, Col 2 sum=5\n\nSolution: (0,1)=1 (0,2)=2 (1,0)=2 (1,2)=3\n```\n","encoding":"utf-8","truncated":false,"total_bytes":1181},"status":null}
