This project imports GitHub repositories and supports code question answering and Git diff impact analysis.

Repository download -> code chunking -> embedding -> pgvector retrieval -> LLM answer

Current focus:

  • AST-based semantic chunking
  • Hybrid retrieval
  • Query rewrite
  • Retrieval evaluation
