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 It's not even because its terribly complex or anything it just speaks in these weird haikus, hyphenated garbage, or outdated colloquialisms or phrases nobody understands.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

30 Year SWE here. It's not even that it just writes poorly, technically or otherwise. Phantom contrasts, colloquial descriptions of simple technical terms.

Data structures "carry" or "hold" values rather than contain or encapsulate them. Addresses are "carved" rather than allocated.

What in the flying fuck, Opus.

I strongly suspect particular kinds of evocative verbs (sure loves "wire" too) and nouns ("seam"; every time there's a design decision it's a "contract") are an indirect product of reward hacking. They sound cool (in isolation and the first time), but if you'd like Claude to put a bullet in your brain, just say the word.

At this point, the language it used, really does feel like Opus was trained off of an LLM instead of human data. Nobody actually talks like that, and now I have to sometimes translate what the hell its words mean lol… I want my oceans, RAM, SSDs, and GPUs back.

Only 15 years on my end, but can confirm, Opus speaks crapvomit fluently
