The JVM has bytecode and .NET has IL. Over the last couple of weeks Screenplay became that for the business: one .play model that people, AI assistants, Studio and your C# code all write, and that VS Code, your MCP host, your running Arc application and the Cratis CLI all draw as the same event model board.
A shared board and canvas where people and AI agents work on the same event model, Screenplay text you can diff, and opt-in code for one slice in your own repository. What Cratis Studio does at each step, and where each step stops.
The sticky-note feature followed from its model to production, into year two and to agents writing its code, through every Cratis product this post names, with 26 more posts that take each one all the way down.
