Does it include tools for performance testing?

Yes, it includes specialized Python scripts for benchmarking latency, throughput, and cost, as well as evaluating retrieval quality using metrics like MRR and NDCG.

What retrieval frameworks does this skill support?

This skill provides implementation patterns and templates for both LlamaIndex and LangChain, the leading frameworks for building RAG systems.

When should I use hybrid search over semantic search?

Hybrid search is recommended as the default for production systems because it combines the conceptual understanding of vector search with the keyword precision of BM25.

Does this skill help with conversational RAG?

Yes, it includes specific examples for conversational retrieval that handle chat history compression and query rewriting for multi-turn interactions.

How does reranking improve my RAG system?

Reranking acts as a second-stage filter that uses more powerful models to re-order the top results from your initial search, significantly improving the relevance of the context provided to the LLM.

Data Science & ML

Implements and optimizes advanced search strategies including semantic, hybrid, and reranking for high-performance RAG systems.

This skill provides a comprehensive framework for building and tuning RAG (Retrieval-Augmented Generation) pipelines using LlamaIndex and LangChain. It offers ready-to-use templates for semantic vector search, hybrid (keyword + vector) search, and cross-encoder reranking, alongside sophisticated benchmarking scripts to measure latency and retrieval quality metrics like Precision, Recall, and NDCG. Whether you are building a prototype or a production-grade system, this skill provides the decision trees and implementation patterns necessary to move beyond basic retrieval to high-precision, context-aware results.
