NameScenarioSource
graphs_state_machinePolling loop — check up to 5 times whether an external job is done; give up if not.src
graphs_with_checkpointsResumable 5-step ETL pipeline — extract / validate / transform / load / notify, snapshot per step.src
graphs_interruptsHITL pause-for-approval — agent drafts an email, graph stops before the send node so a reviewer can approve.src
graphs_semantic_routerCustomer-support intent routing — "refund" → refund_flow, "cancel" → cancel_flow, else general help.src
graphs_topic_channelsOnboarding agent that collects (name, hobbies, todo) across turns — reducers per field (last_value vs. append).src
