Is texting your Coding Agent really the final form? Something that watches your interactions or process execution to surface improvements, or whips up prototypes while you brainstorm seems like the next step.
Not sure why this was flagged, this makes sense but only if inference gets sufficiently cheap. It would be awesome to see a bunch of interactive prototypes and iterate on the UX before ever building the full app. Historically that's been somewhat difficult even with UX designers.
