Ecosystem Primer

langchain-ai/langchain-skills
4.1k installs1.1k stars
Summary

This is the required entry point before writing any LangChain, LangGraph, or Deep Agents code. It walks you through picking the right layer (Deep Agents for planning and memory, LangGraph for custom control flow, plain LangChain for single-purpose agents), sets up LangSmith tracing with the current env var names, and tells you exactly which skill to load next based on your choice. The decision table is terse and opinionated, which is what you want when the ecosystem has three overlapping tools. Load this first, follow the steps, then jump to the layer-specific skill. Skipping it means you'll probably pick the wrong abstraction or use outdated API calls.
