A new tool, mcpscore 1.27.0, has been developed to check these skills against 21 rules, assessing their integrity and security. These checks were run on 25 skills offered by Hugging Face, evaluating aspects like file integrity, frontmatter consistency, and potential security risks such as hidden instructions or embedded credentials within skill descriptions.
