langgraph-checkpoints
LangGraph checkpointing and persistence. Use when implementing fault-tolerant workflows, resuming interrupted executions, debugging with state history, or avoiding re-running expensive operations.
npx skills add majiayu000/claude-skill-registry --skill langgraph-checkpoints --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# LangGraph Checkpointing Persist workflow state for recovery and debugging. ## Checkpointer Options ```python from langgraph.checkpoint import MemorySaver from langgraph.checkpoint.sqlite import SqliteSaver from langgraph.checkpoint.postgres import PostgresSaver # Development: In-memory memory = MemorySaver() app = workflow.compile(checkpointer=memory) # Production: SQLite checkpointer = SqliteSaver.from_conn_string("checkpoints.db") app = workflow.compile(checkpointer=checkpointer) # Production: PostgreSQL checkpointer = PostgresSaver.from_conn_string("postgresql://...") app = workflow.compile(checkpointer=checkpointer) ``` ## Using Thread IDs ```python # Start new workflow config = {"configurable": {"thread_id": "analysis-123"}} result = app.invoke(initial_state, config=config) # Resume interrupted workflow config = {"configurable": {"thread_id": "analysis-123"}} result = app.invoke(None, config=config) # Resumes from checkpoint ``` ## PostgreSQL Setup ```python def create_checkpointer(): """Create PostgreSQL checkpointer for production.""" return PostgresSaver.from_conn_string( settings.DATABASE_URL, save_every=1 # Save after each node ) # Compile with checkpointing app = workf

What does the langgraph-checkpoints skill do?
LangGraph checkpointing and persistence. Use when implementing fault-tolerant workflows, resuming interrupted executions, debugging with state history, or avoiding re-running expensive operations.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill langgraph-checkpoints --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
