I like the direction, but stewarded feels just a little too awkward to type or say to catch on. Perhaps "guide coded"? But it will be really hard to dislodge vibe coded from being generally applied to this concept, I think, in part because it is a catchy little term.

I came to like "vibe coding". Finding the right vibe in the words with the agent to steer them into the direction you want.

Whether the result is slob, depends on the programmer.
