Here is how we built the Multiplayer AI Manifesto page, including the diagrams. • Wrote all copy by hand • Specified the desired vibe with words and images • Used the random-string trick to get design variety • Launched a dozen agents on an Astro template, and compared screenshots • Picked the winner (Fable 5.1) and iterated together in a multiplayer AI chat for over 300 messages Kudos to Lenny Rachitsky and Anshu for the random-string design trick!

Did you know that Claude Code can use the browser to QA its own work? 1. Run `claude mcp add playwright -- npx -y @playwright/mcp@latest` 2. Tell Claude where your app is running, e.g localhost:8000 3. Now Claude can click and type to make sure its code is actually working!

I wanted to better understand how Claude Code is wired under the hood, so I captured its API requests and pulled out the system prompt and tool definitions. Also posting the full thing as a gist below if you want to dig in!
