langgraph-interrupts

To add human-in-the-loop approval to a LangGraph workflow, use dynamic interruptions and static breakpoints to pause graph execution. This allows you to interactively review, approve, reject, or edit AI-generated content before resuming the workflow.

Dynamic interruptions in LangGraph state management pause graph execution at any node to await external input, whereas static breakpoints are set before or after specific nodes for debugging and inspecting outputs. Both prevent AI from proceeding without human oversight.

Yes, you need a checkpointer and thread ID to pause LangGraph execution for tool review. These are required for state persistence and resumption, ensuring the workflow can save its current state during an interruption and resume correctly after human input.

Yes, you can edit AI-generated content before a tool executes in a LangGraph agent by using the tool review mode. This feature interactively pauses the workflow, allowing a human to approve, reject, or edit tool calls before they are actually executed by the graph.

The best way to debug a specific node in a LangGraph workflow is by setting static breakpoints. This feature pauses execution before or after the target node, allowing you to inspect the state and outputs thoroughly before proceeding with the rest of the graph.
