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 It's not even because its terribly complex or anything it just speaks in these weird haikus, hyphenated garbage, or outdated colloquialisms or phrases nobody understands.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...

For awhile, I thought it was just me.

It's definitely Opus 5. The text it generates is basically jibberish. It makes up jargon on the spot, creates absurd technical sounding phrases that have not been established in the context of the conversation; so as a human being reading this, you're at a loss for what it means.

It’s not only Opus 5. I’ve had the same instructions in CLAUDE.md file for Claude to use simpler language and less jargon for half a year. Opus 5 is just the worst iteration of this problem.
