Got sick of debugging LangChain dependency hell? This skill cuts through the ecosystem's package sprawl with current version requirements, compatibility matrices, and minimal working templates. It covers the core langchain/langsmith stack, provider integrations (OpenAI, Anthropic, etc.), and the LangGraph vs Deep Agents decision tree. The skill emphasizes LangChain 1.0+ for new projects and warns about langchain-community's non-semantic versioning gotchas. Includes ready-to-copy requirements.txt and package.json snippets for Python and TypeScript projects, plus environment minimums and tool package recommendations.
