Langgraph

This turns LangGraph's graph-based agent framework into working code patterns. You get StateGraph construction, reducer patterns for complex state management, conditional routing between nodes, and checkpointer setup for persistence. The skill covers the ReAct agent loop with tool calling, multi-agent routing based on query classification, and SQLite or Postgres persistence for production deployments. Worth it if you're building agents that need explicit flow control instead of hoping prompt engineering works. The examples show actual state merging with custom reducers and proper cycle handling, which is where most agent frameworks get messy.
