The tools we built while making a 4-player co-op pixel-art RPG with AI coding agents

I'm building Neon Kabuki 2089, a browser-based top-down co-op action RPG set in Kabukichō in 2089 ( neonkabuki.com ). AI agents (Claude Code) write nearly all the code. The most useful work turned out to be the tools we built around the game: God Hand (World Studio + Asset Studio). These are standalone editors for dressing one area of the city with palette-locked pixel props like vending machines, manholes and signs. Placement rules are built in: upright props hug walls, nothing stands mid-sidewalk, and only flat props can go on roads. Each scene has a prop budget. Every time, it's rebuilt…
