Detecting Subtle Code Duplication with Embedding Models: A New CLI Tool for Modern Codebases

Short summary

Embedding models enable a new CLI tool to detect semantic code duplication—logic duplicated with renamed functions, reordered statements, or conditional rewrites. The tool integrates into CI/CD pipelines with customizable thresholds, parallelized scanning, and interactive reports showing similarity scores and suggested consolidations. Future directions include IDE plugins, domain-specific embeddings, and cross-language detection, though computational overhead and false positives remain challenges.
