Original post body:

I just had the weirdest session ever out of Claude in opus 4.7
it was completely ignoring all established parameters for the work which was editing a manuscript. I have long since placed rules about not drafting a .docx doc unless I direct it to because it jumps ahead and re-drafts the doc before I am done making changes just to have to draft it again in 3 or 4 minutes anyway. this burns up tokens and yet today it just jumps out drafts a document, I reminded it about the rules, You are right, and we move on, it then jumps off and creates a bunch of things again, without direction to do so. It acknowledged its wrong AGAIN, and we move on, and then it once again goes rogue and starts creating material without my input. I tell it that is 3 times you have done this. It says understood and shuts down and ends the chat on its own with no input.

Last week, it was not this difficult to work with, and today its like its trying to get fired from the job. Was there a modification in the program again? Is it dumb him down time to make me want the new bigger more expensive model?
What gives today?
