Use when gameplay, projectiles, actors, world geometry, hazards, cameras, IK or sensors need explicit collision/query categories and a reviewable interaction matrix.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Collision layers This skill owns **stable collision/query category IDs and their interaction matrix**. It does not own hit resolution (`hitbox-hurtbox`), world navigation/body motion, camera collision response or IK contact solving. ## Matrix Publish stable semantic categories and allowed interaction/query pairs, for example project-specific equivalents of: ```text pawn-body world-solid attack-volume hurt-volume grab-volume projectile-volume hazard/sensor camera-query ik-ground-query ``` Names and count are project data. Rendering/costume/material layers are not automatically gameplay collision layers. ## Rules 1. `hitbox-hurtbox` owns attack/hurt/grab meaning and stable hit identity; this skill only allows/blocks candidate layer pairs. 2. World/pawn blocking and movement response stay with the movement/physics owner; `hazard-volume` owns hazard semantics. 3. Projectile friendly-fire/team policy is explicit project data rather than an assumed universal default. 4. `camera-anti-clip` and `ik-foot-locking` use dedicated query masks/categories so presentation probes do not accidentally trigger gameplay contacts. …

How to install
mdr add jammyfu/open-game-skills/collision-layers@sha256:c90749c282c78a22The line at the top of this page pins the label git:20260913.0472540, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
