The Next Game Engine Won't Have a Manual — Arturo Nunez, Nereu
Nereu argues that coding agents need an engine-native vocabulary, not more generated glue code: tags, reusable systems, and selective scene context turn game intent into reliable actions.

Source Summary
Nereu represents game behavior through an **asset tag system** derived from entity-component-system ideas. Its assistant receives scene context, available tools, and tags, while a level-of-detail strategy omits irrelevant objects from large scenes.
Practical Implication
Agent-tool builders should encode domain intent as stable primitives such as player, vehicle, animated, or double jump. That lets an agent compose tested systems instead of rebuilding cameras, movement, and physics from scratch for every request.

That lets an agent compose tested systems instead of rebuilding cameras, movement, and physics from scratch for every request. The product is still in **closed alpha**, and decomposing genres, mood, lighting, and behavior into reusable tags remains ongoing work. The talk demonstrates an approach, not evidence that it scales to production game complexity.
