Hey, thanks for the request. For now, Agents Window uses its own theme engine, so VS Code themes aren’t supported there. Only the basic light and dark themes are available, plus font settings.
The team knows about this, it’s one of the most common requests. Here are a couple threads with the same request:
Right now, if custom themes are critical, you can switch back to the classic Editor Window using Cmd+Shift+P or Ctrl+Shift+P, then run Open Editor Window, and use your usual VS Code themes there.
Let me know if you’ve got any other questions.
