# LangChain Webhooks and Event Dispatch (Python) ## Overview A team wires per-tool webhook dispatch from their LangChain agent via FastAPI `BackgroundTasks` — analytics is always N seconds late because `BackgroundTasks` fire **after** the HTTP response closes, not during the stream (P60). Worse: the `BaseCallbackHandler` they attached via `.with_config(callbacks=[h])` fires on the outer agent but

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