this stuff is a game changer for implementing workflows with some user-facing interaction. I was working on a desktop publishing webapp with a specific slant, the previous iteration of the graphical editor UI was not very good, in order to build anything you have to specifically instruct the agent how every little interaction works, and my recollection and description was often different from how the "standard" desktop publishing flow works (i.e.: this is the sequence of actions to expand a selected entity preserving the aspect ratio, here's how to preserve the center-point, here's how to multi-select, etc). I told the agent "take the frontend from vectorcraft, adopt this specific subset of tools, build it for wasm, and plug in my agent tools and storage backend" - and within a day of deciding to adopt it, I had a much higher quality editor interface that anyone with desktop publishing experience will immediately know how to use, plugged into my storage format.
