🧭 Voyage AI Skill

Uses the vai CLI (voyageai-cli) for Voyage AI embeddings, reranking, and MongoDB Atlas Vector Search. Pure Node.js — no Python required.

Setup

npm install -g voyageai-cli

Common Workflows

Embed → Store → Search Pipeline

# 1. Store documents
vai store --db myapp --collection articles --field embedding \
  --text "MongoDB Atlas provides a fully managed cloud database" \
  --metadata '{"title": "Atlas Overview"}'

# 2. Create index
vai index create --db myapp --collection articles --field embedding \
  --dimensions 1024 --similarity cosine --index-name article_search

# 3. Search
vai search --query "how does cloud database work" \
  --db myapp --collection articles --index article_search --field embedding

Two-Stage Retrieval (Embed + Rerank)

# 1. Get candidates via vector search
vai search --query "database scaling" --db myapp --collection articles \
  --index article_search --field embedding --limit 20 --json > candidates.json

# 2. Rerank for precision
vai rerank --query "database scaling" --documents-file candidates.json --top-k 5

Bulk Ingest Pipeline

# 1. Validate data (dry run)
vai ingest --file corpus.jsonl --db myapp --collection docs --field embedding --dry-run

# 2. Ingest with progress
vai ingest --file corpus.jsonl --db myapp --collection docs --field embedding

# 3. Create index
vai index create --db myapp --collection docs --field embedding \
  --dimensions 1024 --similarity cosine
