Describe the bug

The Plan First toggle no longer sends the plan first mode request. This started about two days ago.

According to Claude this broke in commit 2e640fa. It may not have broken it immediately but recent changes to the api may have cause the lack of the plan first message to break it. I have confirmed this by fixing it in my fork and now it works again.
