UX Feedback States Generator

Registry-first artifact boundary

When `.styleseed/project.json` and `.styleseed/artifacts/index.json` exist, resolve the requested artifact ID first, then read only `.styleseed/bundles/<artifact-id>.md` and `.styleseed/manifests/<artifact-id>.json`. Never fall back to the global legacy bundle for a registry project. Legacy projects may use `.styleseed/effective-rules.md` only when no registry exists.

When NOT to use

• For only the words inside a state → use `/ss-copy`
• For accessibility issues in existing states → use `/ss-a11y`
• For brand-new component creation → use `/ss-component`
• For analytics or error-logging plumbing — UI presentation only

Target: **$ARGUMENTS**

Instructions

1. Read the target file and identify all data-dependent areas.

2. Read the design language reference:

• `DESIGN-LANGUAGE.md` sections on Loading States (Skeleton), Empty States, Error States

3. For each data-dependent area, implement ALL 4 states:

State 1: Loading (Skeleton)

// Skeleton must match the final layout shape
<div className="bg-card rounded-2xl p-6 shadow-[var(--shadow-card)]">
  <div className="flex items-center gap-2 mb-3">
    <div className="size-7 bg-surface-muted rounded-lg animate-pulse" />
    <div className="h-3 w-16 bg-surface-muted rounded animate-pulse" />
  </div>
  <div className="h-9 w-24 bg-surface-muted rounded-lg animate-pulse mb-3" />
  <div className="h-3 w-12 bg-surface-muted rounded animate-pulse" />
</div>

Rules:

• Show skeleton for 300ms minimum (prevent flash)
• Delay skeleton display by 300ms (fast loads skip skeleton entirely)
• Use `animate-pulse` (1.5s cycle)
• Match skeleton shapes to real content dimensions
• Never use spinners inside cards

State 2: Empty (Zero Data)

<EmptyState
  icon={PackageIcon}
  title="No activity yet"
  description="Create your first project to get started."
  action={<Button>Create Project</Button>}
/>

Rules:

• Center-aligned in the card
• Icon: 32px, `text-text-tertiary`
• Title: 14px, `text-text-secondary`
• Always suggest a next action
• Zero values show as "0" (don't hide or dash)

State 3: Error (Load Failed)

<div className="flex flex-col items-center justify-center py-8 text-center">
  <AlertCircle className="size-8 text-destructive mb-3" />
  <p className="text-[14px] text-text-secondary mb-4">Couldn't load the data</p>
  <Button variant="brandGhost" size="sm" onClick={retry}>Try again</Button>
</div>

Rules:

• Partial failure: only affected card shows error, rest loads normally
• Full page failure: full-screen EmptyState with retry
• Error message: plain language, blame the system
• Always provide retry button

State 4: Success (Action Feedback)

// Toast notification for action confirmations
toast("Changes saved")

// With undo for destructive actions
toast("Item deleted", { action: { label: "Undo", onClick: handleUndo } })

Rules:

• Info toast: 3s display
• Action toast (with undo): 5s display
• Toast position: above BottomNav
• One toast at a time (new replaces old)

4. Implementation pattern:

function DataCard({ data, isLoading, error }) {
  if (isLoading) return <DataCardSkeleton />
  if (error) return <DataCardError onRetry={refetch} />
  if (!data || data.length === 0) return <DataCardEmpty />
  return <DataCardContent data={data} />
}

5. Check `prefers-reduced-motion` — disable `animate-pulse` when reduced motion is preferred.
