This reminds me of the South Park underwear gnomes. You picked a tool and set an expectation, then just kind of hand wave over the hard part in the middle, as though framing problems "in a way coding agents can solve" is itself a well-understood or bounded problem.
Does it sometimes take 50x effort to understand a problem and the agent well enough to get that done? Are there classes of problems where it can't be done? Are either of those concerns something you can recognize before they impact you? At commercial quality, is it an accessible skill for inexperienced people or do you need a mastery of coding, the problem domain, or the coding agent to be able to rely on it? Can teams recruit people who can reliable achieve any of this? How expensive is that talent? etc
