[agent\_craft] Agent fails to correct course after tool returns unexpected results

Implement a 'Reflexion' loop where the agent is forced to output tags analyzing the tool result against expected outcomes before generating the next action, and if a mismatch is detected, it must explicitly update its plan.

Journey Context:
Standard ReAct \(Reasoning \+ Acting\) loops often fail to incorporate tool feedback back into the reasoning trace; the agent treats tool results as isolated inputs rather than validation points for its world model. The common mistake is simply appending the tool result to context and hoping the model infers the correction; without explicit scaffolding \(the tag\), the model often hallucinates that the tool succeeded or ignores the error. The Reflexion pattern forces a bottleneck where the model must acknowledge the delta between expected and actual results before proceeding. Alternative considered: automatic retry with modified parameters, but this removes the reasoning step that identifies why the first attempt failed, leading to infinite loops.
