Individual skill
game-spatial-queries
Design and review game spatial query code for raycasts, picking, collision predicates, containment tests, orientation tests, and point/line/plane distances. Use when implementing or debugging ray-triangle hits, point-in-triangle checks, barycentric constraints, signed distance tests, or geometry predicates.

# Game Spatial Queries
Use this skill to turn game picking, collision, containment, and distance
questions into small geometric systems with explicit constraints and failure
cases.
