[Bug] Excessive token usage on new session initialization

[sambua]

Bug Description
[report] could you please explain me what you did with new cleared session, with "Current session" 31% and "Weekly limits" 4%. Guys it's robbery. I've just started session, only one message for planning, only small part of the project and vala unbelievable usage of tokens. Very bad!!!!

It was think off, but Opus 4.5 by fault. But it can't use this one just creating one plan file with 620 line of text (including code examples)

Same here

Same here, I just started my new 5-hour session, and I did only "https://github.com/compact" and checked the usage to find it spent 9% !!!!

The previous session was consumed so freaking fast, and I felt that there was something wrong because I never reach near the limit, but I said maybe I slept on it. But now, it has become obvious that there is some sort of a bug in the way the session limit is being calculated.

Please fix.

Same here.
Every time I JUST OPEN it consumes 4%

Today the same with version 2.0.64, do nothing at all, just exit, enter typed /context +2%, type custom command name, stopped immediately +2% and Current session 4% for nothing. it's bug and should be fixed @claude

Absolutely the same happens to me. Before 2.0.64 with Max plan for me it was impossible (based on my coding tasks/style) to hit the session (5h) limit. After 2.064 - I hit the limit in3.5 hours and was proposed to upgrate plane to bigger capacity.

seems @claude want to rob us showing big income, before go to IPO

As a temporary solution, try to downgrade the version to claude install 2.0.62 and after claude is started, check "Thinking" mode is disabled (for me it always starts with Thinking mode on even with "alwaysThinkingEnabled": false in settings.json)
