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.
