[Bug] Opus 4.7 performance degradation: excessive context consumption and task failures compared to Opus 4.6

Bug Description
all, i was really looking forward to Opus 4.7, but man it's rough. I can't get it to do simple tasks that were easy for Opus 4.6 to do. It basically just chews up context and uses up my 5h window (Pro Max account). This is no bueno. I'm happy to expand more but i'm working on my agent orchestration platform and some mobiles apps and i'm not able to make progress on them with the new model. read more about my work here - https://philjohnstonii.com
