interaction-motion skillA
interaction-motion is agent-read markdown (skill) from vmobifystudio/app-dev-team: Use when specifying or reviewing motion and interaction feel — transitions, gestures, feedback timing, loading and progress. Invoked by product-designer while composing screens and by any IC implementing an animated surface. Triggers whenever something moves, and whenever something takes long enough that the user must be told..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Interaction and motion Motion has one job: **tell the user what just happened and where they are now**. Motion that decorates costs battery, costs frames, and costs the users who cannot tolerate it. ## The durations Do not invent a duration. Use the token, and use the shortest one that reads: | Token | Use | |---|---| | `fast` 150ms ease-out | state feedback — press, toggle, ripple, checkbox | | `base` 250ms ease-in-out | element enters or leaves within a screen | | `slow` 400ms | full-screen transition, only when it carries spatial meaning | Anything longer than 400ms is not motion, it is a wait — and a wait needs progress, not an animation. ## Feedback timing | Elapsed | The interface owes the user | |---|---| | < 100ms | nothing — it feels instant | | 100ms–1s | immediate visual acknowledgement that the input landed | | 1s–10s | a determinate progress indicator if progress is knowable, an indeterminate one if not | | > 10s | the ability to leave and come back, and a way to cancel | A spinner with no cancel on a long operation is a trap; that is a reliability finding as much as a design one. ## The rules …
