Artifacts.iofold
I'm working on https://artifacts.iofold.com, a way to use artifacts (self contained html + optional assets like image/video/json) easily across agents, with feedback loop and docsend style wttribiti gates. Have made it agent friendly enough that my teammates' agents can read and drop commennts on specs/storyboards etc, and my agent can close the loop by iterating with a new artifact version.
