Report #77944

[agent\_craft] Agent repeats the same tool error \(e.g., wrong file path\) across multiple turns because it does not update its internal strategy based on failure feedback

After a tool error, inject a 'Reflexion' step: force the agent to output a block analyzing why the error occurred \(e.g., 'I used a relative path but the CWD is /home/user, not /home/user/project'\) and a block specifying the corrected approach. Append this reflection to the agent's persistent memory \(system prompt or memory bank\) for the duration of the session to prevent recurrence.

Journey Context:
Standard ReAct loops handle single-step recovery but don't encode long-term lessons. Shinn et al. showed that verbal reinforcement learning \(Reflexion\) outperforms standard fine-tuning on coding tasks like HumanEval. The tradeoff is context window consumption \(reflections accumulate\). Alternatives like 'restart the conversation' lose the error context. The specific XML tagging of reflection vs. strategy allows programmatic parsing to extract rules for a 'lessons learned' memory bank. This is distinct from simple 'error messages' because it requires the agent to generate the causal analysis, not just receive it.
