📄 Description

If a developer passes in custom middleware or response format into createDeepAgent the types should properly propagate to the createAgent instance so that the return values from invoke are the same as createAgent. For example:

const agent = createDeepAgent({
  tools: [sampleTool],
  subagents,
  middleware: [ResearchMiddleware],
});
assertAllDeepAgentQualities(agent);
expect(agent.graph.streamChannels).toContain("research");

const result = await agent.invoke(
  {
    messages: [
      new HumanMessage("Get surface level info on lebron james"),
    ],
  },
  { recursionLimit: 100 },
);

result.research // <-- should have proper types
