How does it help with RAG performance?

It provides templates for over-fetching and reranking results with cross-encoders, and offers guidance on choosing the right index types like HNSW for low-latency retrieval.

Which vector databases does this skill support?

The skill includes patterns for popular vector stores including Pinecone, Qdrant, and PostgreSQL via the pgvector extension.

Which distance metrics are covered?

The skill covers Cosine similarity for normalized embeddings, Euclidean (L2) for raw embeddings, and Dot Product for cases where vector magnitude is important.

Does it support hybrid search?

Yes, it includes implementation patterns for combining dense semantic search with sparse keyword search to improve retrieval accuracy.

What is the Similarity Search Patterns skill?

It is a specialized Claude Code skill that provides production-ready implementation templates and best practices for building vector-based search systems.
