What problem does it solve? Placing 3D objects in a game scene often results in floating props, overlapping colliders, or blocked clearances that are hard to detect without evidence. This Skill provides a disciplined inspect-place-verify loop so every placement is grounded in actual physics and bounds data rather than guesswork. ## Core Features & Use Cases - Evidence-driven placement loop: Inspect the scene tree, place the object, query Starcast for support and clearance evidence, correct only the axes the evidence flags, and verify the result. - Placement recipes: Ready-made criteria for floor, shelf, wall, alcove, and rotated-object placements, plus an overlap-repair procedure that moves along the clearest axis. - Result interpretation guidance: Explains grounded status, contact detection, directional clearance, and the difference between exact physics evidence and approximate visual AABB evidence. - Use Case: You need to set a lamp on a shelf without it clipping the back wall. The Skill inspects the scene, places the lamp, runs a Starcast summary, corrects the blocked axis, and confirms support and forward clearance. ## Quick Start Ask the agent to place the crate on the shelf in the current scene and verify with Starcast that it is supported and not overlapping anything.
