This tool, called "undelete," allows users to recover packages removed from NPM and PyPI by querying secondary mirrors that might still have cached versions. It also retrieves package metadata, which is helpful for security researchers investigating malicious deletions. The command-line utility requires Node.js 14 or higher.

Chalk™ enables the capture of metadata during the build process, adding identifiable marks to artifacts and facilitating the understanding of development and production environments. It supports compliance with supply chain standards and allows for easy deployment and integration of security controls in applications. Comprehensive documentation and community engagement are encouraged for users looking to leverage its capabilities.
