wheel-reinvention-detector

Wheel reinvention detector: harvests exported short utility functions (≤40 lines, no class state) and pairs each with the project's installed libraries (package.json, requirements.txt) plus language stdlib hints. LLM judges whether each candidate semantically duplicates an existing stdlib or library API, names the replacement, and notes behavioral differences. Read-only. Audience: Both.
