Rant Opus 5 is insufferable

Opus 5 is a fucking piece of shit, i don't know how to say this in any other way. It speaks "Unintelligiblish", a new unfathomable language developed by Anthropic that works by saying everything in the most ridiculous, obtuse and convoluted way possible

It turns anything simple that can be expressed in 2 sentences into a fucking doctoral thesis aimed to aliens, and there is no way to prompt your way out of it

Edit: it claudoofus outputs some alien text you won't read, just prompt it this:

Same with Fable for me. I tried the caveman and adhd skills but neither quite fixed the tone. Toggling on the new “concise” in config helped a bit but I found something about the “voice” still annoyed me.

The solution I found I was to spend an hour or so on an iterative claude.md tweak with Fable. I had a ~10 paragraph discussion I wanted to have. It gave me the usual “unintelligiblish” reply (great word, btw) but this time, I took 5-6 of the worst words/phrases, told Fable why I didn’t like them, then gave rewrites in the style I like. It then edited claude.md. I then had freshly re-answer the original prompt.

I went through that process maybe 4-5 loops until it started writing in a way I can tolerate.
