moving-platform SKILL.md skillA
moving-platform from jammyfu/open-game-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when riders must stay stable on moving geometry, preserve or discard platform-relative velocity on departure, or handle lifts and crush contacts deterministically.
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
# Moving platform Choose the carry/transfer policy: | Column | Grounded carry | Departure transfer | |---|---|---| | stick-carry | full platform pose delta | published world/relative velocity rule | | loose-carry | partial authored carry | published transfer factor | | one-shot-lift | constrained rider policy | authored exit rule | | crush-safe | any carry policy | explicit stop/yield/damage response | ## Reference frames and order 1. Sample platform previous/current logical transforms and derive platform point velocity/delta for the rider contact point. 2. Grounded rider movement is solved in a declared platform-relative or world-space convention exactly once. Do not both carry by transform delta and add the same platform velocity again. 3. On jump/detach, convert the rider's relative motion to world motion using the published transfer policy. Whether platform velocity is inherited fully, partially or not at all is data, not a universal exception for one lift type. 4. `jump-leniency` owns coyote after support is lost. `platform-jump` owns jump arc. `locomotion` owns rider movement integration. …

How to install
mdr add jammyfu/open-game-skills/moving-platform@sha256:efa376960940bf40The line at the top of this page pins the label git:20260913.624182f, 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.
