I agree, and I'm actually pro Opus 5 exactly for this reason. In my opinion, agents talking to agents is the future, and humans will move to a higher abstraction layer. So it's the right move to make for Anthropic.
Many of the complaints that people are having with Opus 5 are actually acknowledged and explained on opus's 5 prompting guides (https://platform.claude.com/docs/en/build-with-claude/prompt...)
It also seems naive that Anthropic, with some of the smartest people on the planet working on AI, would not know about this.
More likely they know about but cannot fix it without tanking performance. It also effectively pigeonholes them into coding at the precise time they’re trying desperately to expand into general office work. You simply cannot use opus to generate any text fit for humans
