An integrated development environment (IDE)-based approach for processing/analyzing proposed program code libraries as a replacement for existing program code libraries in a networked computing environment is provided. A set of annotations associated with a set of program code files and a proposed (e.g., new, modified, etc.) program code library are received in an integrated development environment (IDE). It may then be determined whether the proposed program code library is an excluded program code library based on the set of annotations. It may also be determined whether the proposed program code library meets one or more thresholds for replacing an existing program code library. If the proposed program code library is not excluded and meets the threshold(s), the proposed program code library may then be provided to a computer device hosting the IDE (e.g., for implementation).
