Since latest releases, when I use auto model mode, the agent stops working seemlessly and gets stuck. I have to switch to non-auto model to fix the issue.
The behaviour is: I prompt agent for a given task, and either the prompt message disappears, or the agent claims the work is done but nothing happens.

在 macOS 26.6.1 上使用版本 1.1.10 的桌面应用，通过自动模型模式重现该问题，然后使用非自动模型比较相同的提示。完成的标准是提示不再消失，并且 agent 执行所请求的工作，而不是在未执行任何操作的情况下声称已完成。
