This skill is only for empty RuleTiles. If there are Sprites or Spritesheets specified by the user, use the tilemap-ruletile-createfromsegment skill instead.\n\n### Step 2: Determine RuleTile Type\nIdentify which RuleTile type to create based on user request:\n- **RuleTile**: Standard rectangular grid\n- **HexagonalRuleTile**: Hexagonal grid layout\n- **IsometricRuleTile**: Isometric grid layout\n\n### Step 3: Create Empty TilingRules\nFor each TilingRule, ensure the Sprite array has one `null` entry.\n\n## Branching Logic (RuleTile Types)\n\n### Path A: RuleTile\n- Use template from `resources/ruletile.md`.\n\n### Path B: HexagonalRuleTile\n- Use template from `resources/hexagonalruletile.md`.\n\n### Path C: IsometricRuleTile\n- Create empty rules with appropriate neighbor positions for isometric layout.\n\n## Important Notes\n\n- **TilingRuleOutput.Neighbor.This**: Use to identify RuleTiles that are the same (matching neighbors).\n- **TilingRuleOutput.Neighbor.NotThis**: Do NOT use unless explicitly specified by the user to ignore a Tile at a certain position."
