Project-Specific Guidelines

Current ML Components

1. Embedding System (orchestrator/context/embeddings.py)

   • Uses sentence-transformers (all-MiniLM-L6-v2)
   • 384-dimensional vectors
   • Cosine similarity search

2. BM25 Index (orchestrator/context/bm25_index.py)

   • Keyword-based retrieval
   • Configurable k1, b parameters

3. Hybrid Search (orchestrator/context/hybrid_search.py)

   • RRF fusion of BM25 + semantic
   • Configurable weights

4. Local LLM Adapters

   • OllamaAdapter: Ollama API integration
   • LlamaCppAdapter: llama.cpp server integration
