LangGraph Persistence
Skill VerificatoINVOKE THIS SKILL when your LangGraph needs to persist state, remember conversations, travel through history, or configure subgraph checkpointer scoping. Covers checkpointers, thread_id, time travel, Store, and subgraph persistence modes.
This skill configures and demonstrates LangGraph's persistence layer, enabling state saving, conversation history, and cross-thread memory. It covers various checkpointer implementations like InMemorySaver, SqliteSaver, and PostgresSaver, along with thread ID management and time travel features for state history.

LangGraph Fundamentals
95INVOKE THIS SKILL when writing ANY LangGraph code. Covers StateGraph, state schemas, nodes, edges, Command, Send, invoke, streaming, and error handling.
Framework Selection
95INVOKE THIS SKILL at the START of any LangChain/LangGraph/Deep Agents project, before writing any agent code. Determines which framework layer is right for the task: LangChain, LangGraph, Deep Agents, or a combination. Must be consulted before other agent skills.
