I started drawing with agents

I began using Pencil as a shared design surface with agents. Instead of asking for a mockup image, I kept the work in an editable .pen file where the hierarchy, copy, spacing, and alternatives could be inspected and changed.

The difference was small and important. I could point to a real node, ask why it existed, move it, and carry that decision into code. The design did not disappear into a screenshot or a chat transcript. That experiment became the basis for how I later designed Loopy's iteration stage and its Buzz integration.
