Use when an interface moves and the movement has to feel right — durations and easing, what must never animate, fixing motion that reads sluggish, cheap or janky, and reduced-motion. Web and native. NOT the visual system (that is `design`), NOT the graded critique (that is `design-loop`).
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
# Motion craft — movement that reads as intent Motion is not decoration laid over an interface. It is the interface **explaining what just happened**: what appeared, what it came from, what is still loading, what the user just did. When motion feels wrong the complaint is almost never "the curve is off" — it is "this feels cheap", or "slow", or "I don't know what happened". Those are the symptoms this skill exists to convert into decisions. ## The one rule **Every animation answers a question the user is already asking.** If you cannot name the question, delete the animation — it is costing time and attention and returning nothing. | The user is asking | The motion that answers it | | --- | --- | | "Where did this come from?" | It enters from its origin, not from nowhere | | "Is it working?" | Immediate feedback, under 100ms, even before the result | | "What did I just do?" | The changed thing moves; nothing else does | | "Where did it go?" | It exits toward where it can be found again | | nothing | **no animation** | That table is the whole method. Everything below is how to honour it without shipping something that janks. ## Duration: the only numbers worth memorising …

How to install
mdr add ericrisco/rsc-harness/motion-craft@sha256:4c867187611d7ec6The line at the top of this page pins the label git:20260901.09d08c9, 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.
