Use the CommandHistory system to execute and undo every building action. The command pattern stores execute/undo pairs, letting you revert any placement, deletion, or modification without rebuilding state manually.

Yes, BlueprintManager handles blueprint serialization and versioning. Save complex build layouts, then load and place them later with full undo support and multi-select capability.

GhostPreview renders placement previews with snapping and color feedback to indicate validity. It shows users exactly where structures will land and whether placement is allowed before commitment.

SelectionManager supports single, additive, box, radius, and connected selection modes. Combine modes for flexible building workflows, then apply batch operations like copy/paste or deletion to all selected objects.

Yes, the Skill handles batch copy/paste operations and blueprint serialization for sharing. Export saved configurations and import them elsewhere with versioning preserved.

Yes, this Skill builds on Three.js fundamentals. You should understand Three.js scene management, object hierarchies, and raycasting to integrate CommandHistory, GhostPreview, and SelectionManager into your game.
