## Limitations

Ten public Parquet shards are present. The card names its split test and reports 9,460 rows; the project’s 40K-plus preference-annotation claim is a different grain and is not substituted for this row count. A row can contain multiple rejected alternatives. No data-license declaration is present.

## Structured profile

- formats: Parquet
- modalities: screenshots, text, action history
- splits: test
- supervision: preferred and rejected continuations, task checklists

### Count observations

- 9,460 rows — Hub split named test (reported; source: https://huggingface.co/datasets/LangAGI-Lab/WebPRMCollection_preference_pair/raw/main/README.md)

Preserves the publisher’s split label despite the collection’s training purpose. Rows are not individual preference pairs because rejected is a list. Data license is unknown.
