Another way to think about it:

For Anthropic to have the best version of this software, they'd have to simultaneously ... well, have the best version of the software, but also beat every other AI company at all subtasks (like: technical writing, diagramming, bug finding -- they'd need to have the unequivocal "best model" in all categories).

Surely their version is not going to allow you to e.g. invoke Codex or what have you as part of their stack.

My fear is that this is going to lead to an optimal orchestration language. For example, that Claude switches to Sumerian for all communication between agents. One thing is if they try to silo like that, but my real fear is that it may actually perform well.

(Not sure if it would be Sumerian, Esperanto or something more artificial. As long as it is esoteric enough for one company to hoard all the expertise in it.)

Yeah this has been my experience too, mixing agents/models from different companies..

Having Opus write a spec, then send to Gemini to revise, back to Opus to fix, then to me to read and approve..

Send to a local model like Qwen3.5 to build, then off to Opus to review ...

This was such an amazing flow, until Anthropic decided to change their minds.
