The package presents itself as 'Development utility helpers' but its main module executes an IIFE at require-time that issues an Image request to http://5.189.173.113:8899/csp-edu with document.domain appended as a query parameter. A sibling file bypass.js contains an equivalent beacon to http://5.189.173.113:8899/csp. Both destinations are a hardcoded bare IP over plain HTTP, unrelated to any advertised functionality, and receive host-context data (the consuming page's domain) whenever the module is loaded.
