Function: ocToolNode()
function ocToolNode<TArgs, TResult>(input: OcToolNodeInput<TArgs, TResult>): OcToolNodeWrapped<TArgs, TResult>;
Defined in: index.ts:204
Wrap a LangGraph tool-node execute path so it produces an OC Agent action envelope per call. The wrapper computes the graph_state_hash inline from the supplied state object, so the verifier replaying the graph against a persisted snapshot gets the same hash deterministically.
Typical shape:
const createInvoice = ocToolNode({ verb: 'invoice.create', execute: async (args) => myInvoiceCreateImpl(args), });
const graph = new StateGraph(MyState) .addNode('createInvoice', async (state) => { const args = pickToolArgs(state); const callId = state.lastToolCallId; const { result, action } = await createInvoice.execute(args, { agent, delegation, callId, graphState: state, }); await audit.append(action); return mergeResultIntoState(state, result); });
