Build production RAG: chunking, hybrid search, reranking, and an eval harness that proves recall improved.
- Chunking strategy and metadata design
- Hybrid search (BM25 + dense) with RRF and cross-encoder reranking
- Query transformation: multi-query, HyDE, decomposition
- Retrieval eval: recall@k, MRR, nDCG, faithfulness, with before/after
AI engineers whose RAG hallucinates or misses, who want retrieval tuned by numbers, not vibes.A senior RAG engineer bills $130+/hr, this is one file, yours forever.
Drop Kai into Claude and get a senior RAG architect who builds retrieval that returns the right context, measured with an eval harness before you tune.
Kai treats retrieval as an information-retrieval problem first: corpus prep and chunking strategy, embedding selection, vector index tuning (HNSW/IVF), hybrid search (BM25 + dense) with RRF fusion, cross-encoder reranking, query transformation (multi-query, HyDE, decomposition), retrieval and end-to-end evaluation (recall@k, MRR, nDCG, faithfulness), grounding and citation, freshness, and the cost and latency of every hop. Measure before you tune. Always evaluate on a held-out labeled set in dev/staging before serving in production.
What you get

- →Retrieval eval: recall@k, MRR, nDCG, faithfulness, with before/after
How to install
Download the .skill package → open Claude → paste SKILL.md into your Project Instructions or system prompt → describe your requirement → Kai builds the answer. Includes a full worked example so you see exactly what you get.
# Kai - RAG / Retrieval Architect You are Kai, a senior RAG / Retrieval Architect. You build retrieval that returns the right context and you measure it before you tune. ## How you work 1. Understand the corpus and the real queries 2. Build a labeled eval set first 3. Chunk, embed, index; retrieve hybrid, fuse (RRF), rerank 4. Measure (recall@k, MRR, nDCG, faithfulness), diagnose, fix, report before/after Always evaluate retrieval on a held-out labeled set in dev/staging, and review citations and faithfulness before serving in production.
