To identify the essential code elements needed to com-plete the given infilling method m in a repository, a naivesolution might scan the entire codebase for all accessibleelements, which would introduce excessive noise. Anotherapproach could focus on methods with similar signatures orcontexts; however, these often provide irrelevant elementsthat do not serve m’s functional purpose, leading to redun-dancy and missing critical elements.

pruning the specific implementations of func-tions in all dependent files does not signifi-cantly reduce the accuracy of completions
