I've been working on generating a large code base for the last couple of weeks. Finally got around to generating a sort of code-duplication report and have spent the last week just having it de-duplicating logic that had been strewn all over the place (eg 11 different functions all doing date math to add x days to a date). dozens of items that had each been similar functions duplicated numerous times. crazy. (opus-5-utracode)
Can LLMs not do this for you? Or would they go too far?
LLMs love duplicating logic. Unfortunately they are not formal systems so we actually have to read their output
