[synthesis] Agent rigidly follows an outdated multi-step plan after the first step changes the environment

Force the agent to replan after every tool execution using only the immediate next step, rather than committing to a long sequential plan generated upfront.

Journey Context:
Developers prompt agents to 'think step by step' and generate a full plan to improve coherence. However, LLMs are bad at predicting the exact state of a dynamic environment multiple steps in the future. When step 1 fails or changes the state unexpectedly, the agent still tries to force step 2 of the original plan, leading to bizarre, out-of-context actions. The synthesis is that long-horizon planning in dynamic environments causes rigid failure; dynamic replanning \(plan-execute-replan\) is essential because the environment's reaction is more informative than the agent's initial prediction.
