Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install langchain4j-vector-store-setup

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent configures a LangChain4j vector store, such as pgvector, Pinecone, MongoDB Atlas, Milvus or Neo4j, adds document ingestion and metadata filters, sets up hybrid search and prepares production tuning and health checks.
