Match Motion to Frequency

SHOULD

SHOULD: Match motion to how often an action happens. Keyboard-initiated and 100+/day actions get no animation; reserve delight for rare or first-time moments.

Match motion to how often an action is seen — frequent and keyboard-initiated actions get no animation

Good

Why it matters

Animation that delights during a first-run onboarding becomes friction on an action performed hundreds of times a day. Give high-frequency and keyboard-driven actions instant feedback; reserve motion for rare or first-time moments.

The rules come from other people's skills and guidelines — Vercel, Rauno Freiberg, @Ibelick, impeccable, Emil Kowalski, Tailwind, RAMS — each one credited on the Sources page. The work here is extraction and wiring: every rule is pulled into one corpus, given a good and a bad example you can operate, a MUST/SHOULD/NEVER rule an agent can paste, and a link back to where it came from.
