LangGraph
Stateful orchestration framework and runtime based on graph nodes and transitions. Useful for agent workflows requiring resumption, interruption and explicit control flow.
This profile summarizes the provider or project documentation. It is not a commercial ranking, independent certification or a guarantee of account-level availability. Versions and pricing change.
Purpose and operating environment
Stateful orchestration framework and runtime based on graph nodes and transitions. Useful for agent workflows requiring resumption, interruption and explicit control flow.
This is a development or orchestration infrastructure. A developer must configure models, tools, access policy, deployment and testing: installing it alone does not create a reliable agent.
A practical application
Build a document assistant with retrieval, synthesis and human-approval stages.
Before starting, define the expected artifact, authorized data, success criteria and actions requiring approval. Keep source links or files. Compare claimed success to the actually observed outcome.
Before your first task
Study graph and state concepts before building a minimal workflow with one tool.
Read setup prerequisites, licensing, model requirements and account restrictions on the provider site. Never paste API keys into a public page or a shared prompt.
Four steps for a controlled evaluation
- 01
Model state transitions
- 02
Define nodes and permissions
- 03
Add a human interruption point
- 04
Trace each transition
Limitations and safeguards
Graphs do not replace API authorization or checking model decisions.
Evaluate answer quality, tool selection, permissions, reproducibility, total cost and prompt injection risk separately. If the agent can send, delete, pay or publish, require explicit confirmation and verify the outcome in the destination system.
- Authorized data and scope
- Actual actions and approval requirements
- Evidence, traces and rollback
- Maintenance, versions, accessibility and access terms
Documentation and references
Vendor documentation describes a product or project rather than serving as independent validation. The OWASP source covers general risks and does not mean OWASP tested or endorsed this tool.
