Bevy

If you're building anything with the Bevy game engine, this skill keeps you from fighting the ECS architecture. It covers component design patterns, system ordering, the plugin structure you should be using, and the UI layout system. The most valuable part is the practical guidance: it points you to the registry examples (your actual source of truth), warns you about expensive rebuilds, and shows you how to structure queries efficiently. Written by someone who's clearly shipped Bevy projects and learned the hard way that pure ECS demands upfront data modeling. Includes specific migration notes for the breaking changes in Bevy 0.17, which alone might save you hours.
