你知道 Claude Code 怎么控制思考时间长短的吗？在提示词里面说：“ultrathink”或者“think harder”或者“仔细思考”，那么它就会真的多思考一会。

不是玄学，而是写在代码里面的，Claude Code 把思考级别分成了 4 档：
- HIGHEST： 32K
- MIDDLE：10K
- BASIC：4K
- NONE： 0

举例来说，如果你说了“ultrathink”，那么它思考的 Token 最长可以到 32K Tokens，如果只说关键字“think”只有 4K，到了 4K 就结束了。如果这些关键字都没有，那么就不会调用 Think Tool（思考工具），直接开始任务。
