Type bag for GraphNode that accepts schema types. All fields are optional - unspecified fields use defaults.
This enables separate input/output schemas for nodes, which is useful when a node receives a subset of state fields and returns different fields.
Schema for runtime context (uses ExtractStateType)
Schema for router state (uses ExtractStateType)
Union of valid node names that can be routed to
Schema for node output/update (uses ExtractUpdateType)
const node: GraphNode<{
InputSchema: typeof NodeInputSchema;
OutputSchema: typeof NodeOutputSchema;
ContextSchema: typeof ContextSchema;
Nodes: "agent" | "tool";
}> = (state, runtime) => {
return { answer: `Response to: ${state.query}` };
};
