# LangChain Content Blocks (Python) ## Overview On Claude, `AIMessage.content` is `list[dict]` even for pure text — so any code from an OpenAI-first tutorial that calls `message.content.lower()` or `message.content.split()` crashes with `AttributeError: 'list' object has no attribute 'lower'` on the first production Claude call (P02). Multi-modal code that works on GPT-4o breaks on Claude because

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