Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Unity Physics Skill Physics system configuration and implementation in Unity. ## Overview This skill provides capabilities for implementing physics-based gameplay using Unity's physics systems (PhysX 3D and Box2D 2D). ## Capabilities ### Rigidbody Configuration - Configure mass, drag, constraints - Set up continuous collision detection - Handle interpolation modes - Manage sleep thresholds ### Collision Detection - Configure colliders and triggers - Set up collision layers and masks - Handle collision events - Implement compound colliders ### Raycasting - Perform raycasts and spherecasts - Use overlap tests - Handle layer filtering - Batch physics queries ### Physics Settings - Configure fixed timestep - Set up solver iterations - Handle physics materials - Manage auto-sync transforms ## Prerequisites - Unity 2021.3+ - Physics module (built-in) ## Usage Patterns ### Rigidbody Setup ```csharp public class PhysicsObject : MonoBehaviour { private Rigidbody rb; void Awake() { rb = GetComponent<Rigidbody>(); rb.interpolation = RigidbodyInterpolation.Interpolate; rb.collisionDetectionMode = CollisionDetectionMode.Continuous; } void FixedUpdate() { rb.AddForce(Vector3.forward * 10f, For

What does the unity-physics skill do?
Unity Physics skill for collision detection, rigidbody dynamics, raycasting, and physics configuration.
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill unity-physics --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
