系统提示 system.md 内指令自相矛盾：MUST make actual changes vs Ask user for clarification

What feature would you like to see?

文件： packages/agent-core/src/profile/default/system.md

问题：

第 18 行要求 Agent "MUST use tools to make actual changes do not just describe"，但第 64 行在同一文件里要求 "Ask the user for clarification if there is anything unclear"，第 108~110 行又要求先理解再改。

这三条指令语气都是强制的，但没说谁优先。结果 Agent：
• 听前者的 → 用户觉得"谁让你直接动手了？"
• 听后者的 → 用户觉得"你怎么光说不做？"

建议：

把第 18~20 行的 "do not just describe the solution in text" 改成 "Once the approach is confirmed, implement it using
the appropriate tools"，把"先确认再动手"内建到主提示里，而不是靠后面的话去对冲。

kimicode有个很严重的倾向，就是讨论方案阶段突然就开始动手干活，令人恼火

Open packages/agent-core/src/profile/default/system.md and compare the instructions around lines 18–20, 64, and 108–110. Align the main instruction with the proposed confirmation-before-action wording, then verify that the resulting text clearly distinguishes discussing an approach from implementing it with tools.
