Claude 新增 effort 控制与 /usage 用量诊断
Claude 新增更细的 effort 控制，在消息中输入 ultrathink 可将单轮 effort 临时提升至 xhigh，无需改动整个会话的设置。用户还可为 subagent 单独指定 effort 级别，例如会话为 high 时让子智能体以 medium 运行。CLI 的 /usage 现在会用直白语言说明是什么在消耗额度，若有快速修复可按 f 直接应用。

You also get a bit more control over Claude's effort.
Typing ultrathink in a message now bumps effort to xhigh for just that one turn, so you can think harder on one problem without changing your setting for the whole session.
You can now also tell Claude which effort level to run a subagent at. If your session is on high but you want the subagents for a task on medium, just ask!
And /usage in the CLI now tells you in plain words what's using up your limits. If there's a quick fix, you can press f to apply it right there.
