[synthesis] Agent rigidly follows an initial plan despite accumulating evidence that the plan is failing or the environment has changed

Shift from plan-then-execute to an iterative 'plan-execute-replan' architecture where the output of every tool call triggers a re-evaluation of the remaining steps, and the system prompt explicitly instructs the agent to discard the original plan if the observation contradicts its premises.

Journey Context:
Planning literature emphasizes accuracy, while execution logs show failures. The synthesis reveals that an initial plan acts as an 'anchoring bias' that distorts the interpretation of new observations. The agent will misinterpret environmental feedback to fit the plan, rather than updating the plan to fit the environment. A replanning loop ensures the agent adapts to reality, treating the plan as a disposable hypothesis rather than a rigid script.
