ui-system skill is no longer a placeholder. Full design-system and
interaction-design interviews with branching, defaults, batched
question clusters, and an 'accept default / skip' protocol so users
move through fast when they have taste and patient when they don't.
Design system interview covers: visual posture, color (with WCAG
contrast verification before writing), typography, spacing, radii,
shadows, density, visual motion, components, theming, and
accessibility tokens (focus ring, hit targets).
Interaction design interview covers: input model, state-surface
declarations per action class, motion posture and triggers,
breakpoints, i18n, four state postures (empty/loading/error/offline),
time formatting, keyboard policy, optimistic-update strategy with
rollback and conflict resolution, gestures, focus management,
notification patterns, selection, and drag-and-drop.
Reference banks for "make it look like Linear/Notion/Stripe/etc."
translate well-known products into starting tokens — user still
confirms each value, no silent invention.
Templates expanded to hold the full output:
- design-system/SKILL.md grew sections for accessibility tokens,
density, dark-mode mapping, contrast verification, theming variants
- design-system/tokens.ts now exports color (light + dark), typography
(family/size/weight/line-height/letter-spacing), spacing + density-
aware padding tokens, radii, shadows, motion (durations + easings),
z-index scale, breakpoints, hit-target minimums
- design-system/components.md gained anatomy/state/a11y coverage for
10 primitives plus an "adding a new component" workflow and a
"patterns to avoid" list (nested cards, color-only meaning, etc.)
- interaction-design/SKILL.md gained sections for optimistic updates,
conflict resolution, gestures, focus management, notification
patterns, selection/multi-select, and drag-and-drop
Hard rules: never invent on the user's behalf; <TBD> instead. Verify
contrast before writing color tokens. Always declare prefers-reduced-
motion as honored.
