'Opus 5 feels, in a word, hostile' (108 upvotes, 63 comments) lists four specific complaints: an apparent per-turn quota of objections, every conversation collapsing into fault-finding, 700-900 word answers regardless of question size, and plausible-looking fake deliverables that require close inspection. It ran alongside 'Claude won't let you be right about anything' (72 upvotes, 77 comments), which describes conclusions never being allowed to stand ('worth holding loosely', 'that's a hypothesis, not a finding'), and 'Claude is a thinking partner. Opus 5 is not Claude.' This is a coherent complaint about a specific post-training tradeoff, not the usual nerf discourse.
