Describe the Bug
Sometimes when I use Opus 5 High as the main model to run my custom Orchestrator Skill, after a long-running session the main model will use the question-asking tool, but it occasionally gets stuck on “Asking questions” for a long time. The loading indicator in the sidebar also disappears, and it looks like the session has frozen. I have not encountered this issue when using Fable 5, Grok 4.5, or Kimi K3 as the main model.
Steps to Reproduce
- Set Opus 5 High as the main model.
- Run a custom Orchestrator Skill.
- Let the session run for an extended period (long-running / multi-step execution).
- Wait until the main model invokes the question-asking tool.
- Observe that the UI stays on “Asking questions” for a long time.
- Check the sidebar: the loading indicator disappears, and the session appears frozen.
