Does it support both Python and TypeScript?

Yes, it provides instructions and code examples for both Python (3.9+) and Node.js (18+) environments.

LCEL stands for LangChain Expression Language, a declarative way to compose chains. This skill includes examples of LCEL patterns using the pipe operator.

Is this skill suitable for beginners?

Absolutely. It is designed specifically as a 'Hello World' entry point for developers new to the LangChain ecosystem.

What does this skill actually do?

It generates minimal, working boilerplate code for LangChain in Python or TypeScript, helping you verify your setup and understand basic chain syntax.

Do I need an API key to use the generated code?

Yes, you will need valid credentials from an LLM provider like OpenAI or Anthropic to execute the code successfully.
