Legit this morning Claude was essentially unusable for me
I could explicitly state things it should adjust and it wouldn't do it.
Not even after specifying again, reverting everything eventually and reprompt from the beginning etc. Even super trivial frontend things like "extract [code] into a separate component"
After 30 minutes of that I relented and went on to read a book. After lunch I tried again and it's intelligence was back to normal
It's so uncanny to experience how much ita performance changes - I strongly suspect anthropic is doing something whenever it's intelligence drops so much, esp. Because it's always temporary - but repeatable across sessions if occuring... Until it's normal again
But ultimately just speculation, I'm just a user after all
