+# COSPLAN
+
+A composite visual-planning benchmark with four multiple-choice subsets. Each
+subset is a separate config in HuggingFace `imagefolder` format (images +
+`metadata.jsonl`). Every row has an `image`, a `prompt`, and a `correct_option`
+(A/B/C/D).
+
+| Config | Items | Task |
+|--------|-------|------|
+| `checkboard`   | 4896 | Grid path planning around obstacles |
+| `blocksworld`  | 5000 | Block-stacking move-sequence selection |
+| `imagenet`     | 1000 | Image-patch rearrangement validation |
+| `robovqa`      |  300 | Robot action-sequence selection |
+
+## Usage
+
+```python
+from datasets import load_dataset
+ds = load_dataset("shrg7/COSPLAN", "blocksworld", split="test")
+print(ds[0]["prompt"], ds[0]["correct_option"])
+```
