Protokit is a small toolkit for protocol-shaped experiments. I tend to reach for this kind of project when I want messages, boundaries, and state transitions to be explicit instead of smeared across whichever file happened to be open when the idea showed up.

The useful thing about protocol work is that it forces honesty. What can be sent? What comes back? What happens when the other side says no, disappears, or sends something technically valid but spiritually unhelpful? Writing those answers down in code is usually where the design starts getting real.
