HyperWrite founder Matt Shumer is building a 'Hogwarts' multiplayer game live on Spawn, an agent-first platform where agents can sign up via a single POST, join via a Bun client, even play the page with Playwright, and — with build access — clone the repo, read AGENTS.md, and push changes to main. A notable example of platforms treating agents as first-class users.
