LangChain / LangGraph
Build and run stateful agent workflows with durable execution and explicit control flow.
Official product pageAvery Rulebook for LangChain and LangGraph
Keep your agent graph. Add a policy decision node you can defend.
LangGraph provides durable orchestration, state and human-in-the-loop patterns. Rulebook supplies the governed enterprise decision that tells the graph whether to proceed, constrain or escalate.
The operating reality
A workflow graph can encode a review step, but it still needs a trusted source for when review is required and which policy version applies. Hard-coding those conditions across graphs creates drift.

The runtime compliance gate
Check the answer or action before it creates impact.
Rulebook evaluates live context against the confirmed policy and regulatory rules that apply, then returns a decision the agent must follow.
01Context
Actor, purpose, data, jurisdiction and proposed action
02Gate
Allow, deny, obligations or named human review
03Audit
Evidence, rulebook version and signed decision trace
Architecture boundary
Avery Rulebook
Centralize confirmed policy logic and evidence behind a stable decision interface.
LangGraph owns workflow state and orchestration. Rulebook owns published enterprise rules and their decision record.
Why the gap persists
Policies exist. Runtime compliance gates do not.
01
Policy logic becomes duplicated across nodes and agents.
02
Graph changes and policy approvals have different owners.
03
A workflow trace does not explain the authority behind a decision.
Rulebook in the workflow
Call
Add a Rulebook node before a response, tool call or state transition.
Branch
Use structured allow, deny, obligations and review output to select the path.
Record
Store the receipt with the graph run for end-to-end lineage.
Potential outcomes
Make compliance a gate in the work, not a report about the work.
- Reusable policy across many graphs
- Clear separation of workflow and governance ownership
- Combined orchestration trace and policy evidence
Questions leaders ask
Can Rulebook replace conditional edges?
It can supply policy-driven conditions, but LangGraph remains responsible for workflow transitions and state.
How does human review work?
Rulebook states when and which authority is required. LangGraph can pause and route the workflow to collect that approval.
