All right so what do I need to do so it does its job again? Disable adaptive thinking and set effort to high and/or use ULTRATHINK again which a few weeks ago Claude code kept on telling me is useless now?
You can't. This is Anthropic leveraging their dials, and ignoring their customers for weeks.
Switch providers.
Anecdotally, I've had no luck attempting to revert to prior behavior using either high/max level thinking (opus) or prompting. The web interface for me though doesn't seem problematic when using opus extended.
Agreed, the only feedback is switching... however things move fast. Unfortunately that means for me is subscribing or using API for many providers and then just switching models when one gets worse.
If you have a paid plan, you may need to pay for more than one, and "hopefully" the drop in usage (not income) is a good enough signal that there is a issue.
