# LangChain Reference Architecture (Python) ## Overview Eight months into a LangChain service, a code review surfaces the mess. Twelve chain definitions live inlined inside FastAPI route handlers. Three retrievers are constructed at module-global scope, one bound to `tenant_id="acme"` because that was the first tenant in the pilot — that retriever now returns Acme's documents to every other tenant

How do I install it?
Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill langchain-reference-architecture --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From jeremylongshore/claude-code-plugins-plus-skills, a repository with 2,596 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
