Use when lava, spikes, wind, pits, poison clouds, or other spatial gameplay hazards need authored volumes, stable overlap identity, tick/kill/push policy, and evidence independent from decorative meshes.
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
# Hazard volume Ask: `tick-damage | instant-kill | push-field`. ## Ownership The hazard owns its gameplay volume and effect policy. Decorative art is not the oracle. Hit filtering remains compatible with `hitbox-hurtbox` / `collision-layers`; recovery or fall policy may delegate to `fall-rules`. ## Contract Publish: - stable `hazard_id` - authoritative volume shape/transform - effect mode and project gameplay-clock policy - target filters / immunity policy - enter/stay/exit event identity - cue/reference IDs used by presentation For periodic effects, define the tick schedule from the project's gameplay clock and guarantee at-most-once application for one hazard/target/tick identity. Re-entering, pause/resume, streaming and rollback must not duplicate an already committed effect. For instant-kill or forced recovery, the project defines the cue and recovery contract; this skill does not require one universal telegraph style. ## Acceptance …

How to install
mdr add jammyfu/open-game-skills/hazard-volume@sha256:17efded156781576The line at the top of this page pins the label git:20260913.192cca5, 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.
