What Ukiyo does

Agent-native game engine in C#. Your coding agent reads and changes the running game through skills and MCP; you watch and edit in the Studio. Assemble it like Arch Linux: simple, balanced or complete. Pre-alpha.

README

The world is code. Agents build it. You watch every tick.

An agent-native game engine in C#. Your coding agent reads and changes the game's code while it runs,
through skills and MCP. The Studio is the human window: watch, edit, take over.
Assemble it like Arch Linux: simple, balanced or complete.
Pre-alpha. 0.0.1 ships the core: one program on three targets. Skills, MCP and the Studio come next.

The same Program.cs rendered on wgpu/Metal and on three.js/WebGL2, tick by tick

Same Program.cs. Left: native window, wgpu → Metal. Right: browser, .NET WebAssembly → three.js.
Every frame was read back from each renderer at the same tick. Nothing here is a mockup.
