Builds and edits 3D models in the user's Blender through a Blender connection (the official Blender Lab server or MCP for Blender) - inspecting the scene, writing bpy code in small verified steps, real-world scale, clean naming, modifiers and checking the result with viewport screenshots. Use when the user asks to model, build, create, fix or change an object or a scene in Blender, or to make a 3D model from a description or a reference image.
