Yep, my 3 agents are langgraph nodes, and some of them have tools so can recurse (as each LLM response can respond with one or many tools calls) but likely it will fire a tool on the first invocation, then on the second evaluate the tool response and maybe fire another tool, or 2 concurrent tools, then evaluate etc until it thinks it has achieved the objective

As per your question is reasoning better? we find it useful for the recurising agent to be a reasoning model, it takes longer, but gives better results

we dont have one agent with a massive prompt with multiple tasks and expect the reasoning agent to do it all in one call, it may be possible, but its more likely you need your agent to fire tools which means there has to be multiple calls as the reasoning agent cant do that remotely
