What is building-maps?
Build maps, areas, zones, and large-scale environments in Roblox Studio via MCP. Use when: user asks to create a map, battle arena, lobby, hub, town, village, open area, game world, level design, or any environment that spans multiple zones or regions. Triggers on: "マップを作って", "エリアを作って", "フィールドを作りたい", "build a map", "create an arena", "make a lobby", "design a level", "make a hub world", "create a town", or any request involving spatial layout, zone planning, or multi-area environments. Scope boundary: applies to multi-zone layouts. For a single object, prop, or room interior → use building-3d-objects instead. Source: ohzw/roblox-dev-skills.
