The value for Anthropic / OAI is that they have a strong interest in becoming the "default" agent.
The one that you don't need to install, because it's already provided by your package manager.
I think they're more into the extra context they can build for the LLM with ruff/ty.
$ curl 'claude.ai/install?key=abcd123' | bash -e
$ claude 'finish laptop setup from http://github.com/justjake/Dotfiles'
claude will be the one to install / set up the system, not the other way around. claude was certainly the one who installed `uv` on my current machine.
