LangGraph | FishMem Docs

LangGraph 为图执行保存 checkpoint。FishMem 则补充跨运行的持久结论与来源 RAG。

在需要长期上下文的节点之前加入召回节点；只有图获得已验证结果或更正后，才加入写入节点。

async function recallNode(state: AgentState) {
  const { results } = await fishmem.memories.search({
    query: state.latestUserMessage,
    user_id: state.authenticatedUserId,
    agent_id: "support-graph",
    top_k: 6,
  });
  return { recalledMemories: results };
}

async function rememberNode(state: AgentState) {
  if (!state.verifiedOutcome) return {};
  const event = await fishmem.memories.addAsync(
    { content: state.verifiedOutcome, user_id: state.authenticatedUserId, agent_id: "support-graph" },
    { idempotencyKey: `case:${state.caseId}:outcome` },
  );
  return { memoryEventId: event.event_id };
}

不要把 API Key 或模型可修改的任意作用域放进图状态。应由服务端运行时注入 FishMem 客户端与已认证身份。
