@agentic.james: Stop using ASCII diagrams to plan your UI, use HTML specs instead. I just mean a quick HTML mockup of the screen you want the agent to build. It's dirt cheap to generate and you get the actual layout plus every state, error, loading, toggles, all of it. You can bake local acceptance criteria right into each element so the agent reads exactly what done looks like, and drop in test IDs so Playwright has something real to grab onto. Way more signal than a diagram or a paragraph in a markdown file. Link in bio.
