Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
So this is pretty severe actually since it’s “the core product”.
In plan mode, I get stuck in loops between “Flutter analyze” → Chat summarized → Checking last thing on the todo → Flutter analyze.
This way, the plan never gets really finished.
Steps to Reproduce
How to reproduce bug:
Make sure Opus 4.5 is selected as model.
When I create a plan → Click “Build” → Let it do it’s thing → The model get stucks in “Running Flutter analyze” and then doing "Chat context summarized → Checking last thing on the TODO → Doing Flutter analyze → “Chat context summarized” → Checking last thing on the TODO → Doinf Flutter analyze.
I have to quit this manually every time and it costs me so extremely much money. For some reason it fills upp the context window for every loop.
Expected Behavior
When there’s no errors in Flutter analyze → Check the last bullet on the plan/todo. Don’t do “chat summarized” and restart the loop.
