Opus 4.7+ and 5 being annoying and incoherent reads like a portent of things to come: Anthropic is clearly all-in on building persistent end-to-end agents that act autonomously and direct agent swarms. As such, they feel less of a need to spend R&D time on making the outputs pleasant to read for humans(especially at the cost of capability anywhere else) when humans aren't part of the intended operating environment.

That can be true. On multiple occasions when claude did some BS I have asked it why and it explained that it is optimizing for task completion and not for communication.

We are almost literally being left out of the loop, gradually.-
