Build 3D objects, props, and room-scale structures in Roblox Studio via MCP. Use when: user asks to create, build, or place a single physical object — furniture, animals, vehicles, gates, towers, decorations, street props, room interiors, or any individual tangible structure. Triggers on: "○○を作って", "○○を置いて", "build me a ___", "create a ___", "make a ___" in the context of Roblox Studio. Also use when user mentions CSG, Union, Subtract, Part placement, or 3D modeling in Roblox. If the user is in a Roblox project and asks to "make" or "build" something physical, this skill should trigger even without explicit mention of "3D" or "Roblox". Scope boundary: applies if the result can be grouped into a single `Model`. For full maps, arenas, lobbies, hubs, or multi-zone environments → use building-maps instead. Dispatch rule: When the user requests multiple related/variant objects (e.g., "5 types of swords", "3 chair styles"), dispatch ALL variants to a SINGLE agent. Do NOT spawn parallel agents. Consistency requires
Retrospective analysis skill for Roblox 3D object building sessions. It analyzes what worked, what failed, and why, then feeds validated learnings back into roblox-object-builder docs. Trigger after Roblox builds that create or modify Parts, Models, CSG, or map elements via mcp__roblox__run_code, and when users request review keywords such as "振り返り", "retrospective", "what went wrong", or "analyze the result".

Tech stack: jsdotlua/react, ReactRoblox, react-spring (chriscerie/react-spring), Luau --!strict, Rojo, Wally.
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.
Interactive design consultant for Roblox objects. Use when the user's request is abstract or lacks structural details. This agent specializes in extracting requirements through dialogue BEFORE any implementation begins. Triggers on: abstract requests like "make a kitchen", "build something cool", or when building-3d-objects detects fatal ambiguity.
