Literally any coding agent marking material:

- https://cognition.com/

- https://openai.com/index/introducing-the-codex-app/

- https://www.anthropic.com/news/claude-3-7-sonnet

anthropic specifically brags about how good claude code is every annoucement of a new model. I will surrender that none of them claim its "to perfection", but IMO its implied because no one would claim that their model one-shots any issue to dog shit quality.

I don't really think they advertise "Create your app idea in one weekend night" and assume the general public will mentally add "... but hire an experienced developer to supervise the process".
