If you're building anything in MapleStory Worlds, read this first. It enforces a core principle: MSW isn't about prototypes, it's about polished games, so every entity needs proper sprites, animations, and sounds applied via the search skill. The real value is the workflow discipline it hammers in: never start models from scratch (use the validated template catalog), always use builders instead of hand-editing files, and if an entity appears twice or more in a map, author a model first and place instances rather than copying inline components. The preflight rules are strict (read entity.md before touching entities, read builder-protocol.md before any file writes) but they exist because the three builders are interlocked and skipping documentation breaks the component sync contracts.
