[Bug] Excessive token consumption in recent Claude Code versions

Bug Description
I was a loyal customer for a long time now did not face this kind of problem but since few days my tokens are burned so fast with few prompts I am done I feel like now they are ripping us off. I am on 20x plan. Previously I barely hit usage limits. Claude usage gets burned absurdly fast for serious work, even with tools/features disabled.
