# LangChain LangGraph Agents (Python) ## Overview Two failure modes hit every team writing their first LangGraph 1.0 ReAct agent: **Loop-to-cap on vague prompts (P10).** `create_react_agent` defaults to `recursion_limit=25`. A prompt like "help me with my account" never converges — the model calls a retrieval tool, gets irrelevant results, calls another tool, and repeats until `GraphRecursionError

How do I install it?
Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill langchain-langgraph-agents --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.
