My biggest frustration right now is the seeming complete loss of background agent functionality. Permissions seem completely botched for background agents right now. When that happens, the foreground agent just takes over the task despite:

1. Me not wanting that for context management reasons

2. It burning tokens on an expensive model.

Literally a conversation that I just had:

* ME: "Have sonnet background agent do X"

* Opus: "Agent failed, I'll do it myself"

* Me: "No, have a background agent do it"

* Opus: Proceeds to do it in the foreground

* Flips keyboard

This has completely broken my workflows. I'm stuck waiting for Opus to monitor a basic task and destroy my context.
