 Build and save the full initial scene in the editor: models, objects, camera, lighting, colliders, UI and script attachments must be inspectable before Play.

Use `object_create` for empty nodes, cameras, lights and deliberate blockouts; `model_create` places finished mesh assets. `object_update` changes names, parent, local xyz translation/scale, xyzw quaternion rotation, part attributes (color, anchored, can_touch, can_collide), cameras, lights and object script components. These tools use the editor's document validation and undo history; do not click inspector controls through computer use. They affect the active scene only.

+
+# Lay out the scene explorer
+
+The scene explorer (Hierarchy panel) represents the active scene's objects and parent links. A folder is an organizational scene entity with `folder:true`, not a disk directory or a separate scene. Creating a directory through file tools does not create an explorer folder. This skill organizes scene content; dock/tab layout is a separate editor preference.

+1. Call `workspace_info`, read project instructions, and open that project in its writable editor. Read `editor_status` for live IDs, names, `folder` flags, parents and transforms. Saved-file `scene_summary` also reports folder flags, but does not include unsaved edits.
+2. Match the hierarchy to the game. For a small scene, a few root groups such as World, Gameplay, Lighting and UI may suffice. Within World, group by area or responsibility (Town/Buildings, Forest/Vegetation); within
