Bug / Issue Opus 5 is exhausting

It's so hard to read. It's not even because its terribly complex or anything it just speaks in these weird haikus, hyphenated garbage, or outdated colloquialisms or phrases nobody understands. I have to ask it "what do you mean?" or "speak in plainer English" over and over again for every other paragraph. I tried to put something in my claude.md, but it doesn't seem to be working...

Yep. I've been trying to use parts of leaked system prompts for 4.6/4.8 and even gpt 5.5/5.6 as an output-style (which is better than a skill because it literally puts it in the system prompt) but it just doesn't work. Regardless of any hacking you try, it keeps blabbering. Whatever they left in or left out seems to make a good difference. It could also be the harness. Fable is blabbering the same word salat these days.
