Developer proposes 'receipt card' method to validate CLI projects before merging

This method is designed to provide a clear, automated checkpoint to prevent unfinished or over-scoped work from being merged. The article was prepared as part of an outreach effort for MonkeyCode, which offers free tools for drafting and testing such projects.
