finding-duplicate-functions

LLM-generated codebases accumulate semantic duplicates: functions that serve the same purpose but were implemented independently. Classical copy-paste detectors (jscpd) find syntactic duplicates but miss "same intent, different implementation." This skill uses a two-phase approach: classical extraction followed by LLM-powered intent clustering. Options: Test files ( *.test.* , *.spec.* , __tests__/** ) are excluded by default since test utilities are less likely to be consolidation candidates. Dispatch a haiku subagent using the prompt in scripts/categorize-prompt.md . Insert the contents of catalog.json where indicated in the prompt template. Save output as categorized.json . Creates one JSON file per category. Only categories with 3+ functions are worth analyzing.
