ClawHub Skill Dataset
This dataset contains 26,502 normalized records of public skills collected from the ClawHub / OpenClaw ecosystem (up to 18, March, 2026). It is intended for research on skill ecosystems, agent capability marketplaces, skill safety, and submission-time risk prediction.
Contents
Each record may include:
- skill identity and owner information
- metadata such as title, summary, tags, downloads, stars, comments, and versions
- creation and update timestamps
- uploaded file manifest
- text content extracted from primary documents and other text-like files
- platform-visible risk labels and reason codes when available
- derived structural features used for downstream analysis
Research Use Cases
This dataset can support research on:
- skill ecosystem measurement
- functional clustering of skills
- cross-lingual comparison of English and Chinese skills
- risk and safety analysis
- submission-time skill risk prediction
- popularity and adoption analysis
Notes
- The dataset is built from publicly accessible skill records.
- Some safety-related fields may be missing, incomplete, or platform-dependent.
- Risk labels should be interpreted as platform-observed signals rather than definitive ground truth.
- Text fields may contain user-authored content, API names, environment-variable names, and executable instructions from the original skill descriptions.
License
Please follow the original platform terms and any applicable downstream usage restrictions when using this dataset.
