LangGraph
A toolkit for building agents as a map of steps.
The fuller definition
LangGraph is a framework for orchestrating stateful workflows and agents, with explicit control over steps, transitions, and persisted state.
- State
Current task information
- Nodes
Processing operations
- Transitions
Rules for the next operation
A simplified relationship, not a screenshot or a complete design.
A concrete example
A document workflow pauses for review, records its state, and resumes at the appropriate next step.
The distinction that matters
A graph specifies how execution proceeds; its design still needs correct permissions, failure handling, and evaluation.
