Captures learnings, errors, and corrections to enable continuous improvement. Use when: (1) A command or operation fails unexpectedly, (2) User corrects Claude ('No, that's wrong...', 'Actually...'), (3) User requests a capability that doesn't exist, (4) An external API or tool fails, (5) Claude realizes its knowledge is outdated or incorrect, (6) A better approach is discovered for a recurring task. Also review learnings before major tasks.

捕捉学习成果、错误与修正，以实现持续改进。适用场景包括：(1) 命令或操作意外失败；(2) 用户纠正Claude（如“不对，错了…”、“实际上…”）；(3) 用户请求不存在的功能；(4) 外部API或工具失效；(5) Claude意识到自身知识已过时或错误；(6) 为重复性任务发现更优方法。在执行重要任务前，请回顾这些学习记录。
