Builds semantic/vector search — pick an embedding model + dimensionality (and whether to truncate Matryoshka dims) and the matching distance metric (cosine/dot/L2, normalize to unit length so cosine == dot and IP is correct), an ANN index with the recall/latency/memory tradeoff understood (HNSW M/efConstruction/efSearch for low-latency RAM-resident; IVF-PQ nlist/nprobe/PQ for billion-scale compressed; flat/exact for <100k) in pgvector/Qdrant/Milvus/FAISS/Pinecone, chunking + overlap + per-chunk metadata for filtering, HYBRID retrieval fusing BM25 + dense by Reciprocal Rank Fusion (RRF, k≈60) not score addition, a cross-encoder/Cohere reranker over the top-50→k, correct pre-filter-vs-ANN interaction (filterable HNSW, not post-filter that starves k), and offline eval with recall@k / nDCG@10 / MRR against a labeled qrels set. Quantize (scalar/PQ) only after measuring recall loss; tune efSearch/nprobe to a recall target, not a guess.

Frequently asked questions

How do I install the Build Vector Search Claude Code skill?
Install via the ClaudSkills desktop app (one click) or copy SKILL.md from the source repository to ~/.claude/skills/build-vector-search/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.
What does the Build Vector Search skill do?
Builds semantic/vector search — pick an embedding model + dimensionality (and whether to truncate Matryoshka dims) and the matching distance metric (cosine/dot/L2, normalize to unit length so cosine == dot and IP is correct), an ANN index with the recall/latency/memory tradeoff understood (HNSW M/efConstruction/efSearch for low-latency RAM-resident; IVF-PQ nlist/nprobe/PQ for billion-scale compressed; flat/exact for <100k) in pgvector/Qdrant/Milvus/FAISS/Pinecone, chunking + overlap + per-chunk metadata for filtering, HYBRID retrieval fusing BM25 + dense by Reciprocal Rank Fusion (RRF, k≈60) not score addition, a cross-encoder/Cohere reranker over the top-50→k, correct pre-filter-vs-ANN interaction (filterable HNSW, not post-filter that starves k), and offline eval with recall@k / nDCG@10 / MRR against a labeled qrels set. Quantize (scalar/PQ) only after measuring recall loss; tune efSearch/nprobe to a recall target, not a guess.
Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Build Vector Search skill?
Use Build Vector Search when your Claude Code task falls under the General category — specifically in the general misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Build Vector Search" or describe the task and let Claude pick). Browse related skills at /category/general/.
What is a Claude Code skill and how does the Build Vector Search skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Build Vector Search is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.
