What's Wrong?

I was only using Claude code, and after the limit renewed it immediately jumped at 47% with a single simple chat –– which is completely different from the way Claude worked for me for the past 3 months.

After a renewed usage session, a /compact command drained 30% of my usage, which is crazy!
