Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install langchain-llm-app-framework

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 guides you through installing LangChain, configuring a model, creating a ReAct agent with tool calling and memory, then connecting a vector store for RAG. You get a codebase for a chatbot or a document assistant.
