CloneGuard

About

CloneGuard is a research tool that automatically 
detects code clone propagation introduced by AI 
coding assistants like GitHub Copilot — before 
the developer accepts the suggestion.

HOW IT WORKS:
1. Reads all existing code from your GitHub editor
2. Builds a live index using Karp-Rabin hashing
3. When Copilot suggests code — checks against index
4. Shows warning if Type 1 or Type 2 clone detected

FEATURES:
- Real-time clone detection — fires automatically
- Detects Type 1 (exact) and Type 2 (renamed) clones
- Live codebase index built from your current file
- Non-blocking warning popup with similarity score
- Shows matched function name and line number
- Works on github.com and github.dev
- All processing done locally — no code sent externally

WHAT ARE CODE CLONES:
Type 1 — Exact clone: identical code copied verbatim
Type 2 — Renamed clone: same logic, different variable names

Built for research at Stevens Institute of Technology.
