UX Feedback States Generator

When to Use

Use this skill when you need add appropriate user feedback states (loading, success, error, empty) to a component or page.

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.

Limitations

• Use this skill only when the task clearly matches its upstream source and local project context.
• Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
• Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
