# LangGraph Streaming (Python) ## Overview An engineer ships `stream_mode="values"` to a token-level chat UI because it "seemed the most complete." Every single token causes the full graph state — message history, scratchpad, plan — to be re-sent and re-rendered. At ~60 tokens/sec the browser overdraws, the React reconciler can't keep up, the tab freezes, and users blame the model. The correct ans

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