What's Wrong?

On the windows desktop app (probably also on mac). There is a error that the prompt is too long while the agent is running. But the context is only filled to 51% (101.5k tokens). This happens often on long running tasks. there is no option to auto compact, or just remove older context so this screws up the workflow.
This started happening on the new desktop app, never had this issue before.

What Should Happen?

Agent should continue running and the desktop app should have features to mitigate this behaviour.
