name	i-delight
description	Use when the user says: "add delight", "make it more fun", "moments of joy". Add micro-interactions and moments of delight to interfaces.
user-invocable	true

Identify opportunities to add moments of joy, personality, and unexpected polish that transform functional interfaces into delightful experiences.

MANDATORY PREPARATION

Read ~/.claude/skills/i-frontend-design/SKILL.md for design principles, anti-patterns, and the Context Gathering Protocol. Follow the protocol before proceeding — if no design context exists yet, you MUST run /i-teach-impeccable first. Additionally gather: what's appropriate for the domain (playful vs professional vs quirky vs elegant).

Assess Delight Opportunities

Identify where delight would enhance (not distract from) the experience:

1. Find natural delight moments:

   • Success states: Completed actions (save, send, publish)
   • Empty states: First-time experiences, onboarding
   • Loading states: Waiting periods that could be entertaining
   • Achievements: Milestones, streaks, completions
   • Interactions: Hover states, clicks, drags
   • Errors: Softening frustrating moments
   • Easter eggs: Hidden discoveries for curious users

2. Understand the context:

   • What's the brand personality? (Playful? Professional? Quirky? Elegant?)
   • Who's the audience? (Tech-savvy? Creative? Corporate?)
   • What's the emotional context? (Accomplishment? Exploration? Frustration?)
   • What's appropriate? (Banking app ≠ gaming app)

3. Define delight strategy:

   • Subtle sophistication: Refined micro-interactions (luxury brands)
   • Playful personality: Whimsical illustrations and copy (consumer apps)
   • Helpful surprises: Anticipating needs before users ask (productivity tools)
   • Sensory richness: Satisfying sounds, smooth animations (creative tools)

If any of these are not answered by design context (design/context.md, .impeccable.md, or design/direction.md), STOP and call the AskUserQuestion tool to clarify. Use the answer to inform your delight strategy. If the answer is unclear or deferred, proceed with micro-feedback only as the safe default — no personality changes.

CRITICAL: Delight should enhance usability, never obscure it. If users notice the delight more than accomplishing their goal, you've gone too far.

Delight Principles

Follow these guidelines:

Delight Amplifies, Never Blocks

• Delight moments should be quick (< 1 second)
• Never delay core functionality for delight
• Make delight skippable or subtle
• Respect user's time and task focus

Surprise and Discovery

• Hide delightful details for users to discover
• Reward exploration and curiosity
• Don't announce every delight moment
• Let users share discoveries with others

Appropriate to Context

• Match delight to emotional moment (celebrate success, empathize with errors)
• Respect the user's state (don't be playful during critical errors)
• Match brand personality and audience expectations
• Cultural sensitivity (what's delightful varies by culture)

Compound Over Time

• Delight should remain fresh with repeated use
• Vary responses (not same animation every time)
• Reveal deeper layers with continued use
• Build anticipation through patterns

Propose Changes

After analyzing the current state, present your proposed changes to the user:

1. Assessment: What's wrong and why (your domain analysis above)
2. Proposed changes: Specific changes ranked by impact, with rationale
3. Verification plan: What to check after implementation (LLM self-check items + Playwright verification if available)

Then STOP and confirm before implementing:

AskUserQuestion:
  question: "Here's what I propose. How would you like to proceed?"
  header: "Confirm"
  options:
    - label: "Implement"
      description: "Looks good — go ahead and make these changes."
    - label: "Refine scope"
      description: "I want to adjust what's included before you start."
    - label: "Challenge this first"
      description: "I'll run /mine.challenge against your proposal before we proceed."
    - label: "Stop here"
      description: "Don't implement anything. The proposal is in this conversation only."

If "Implement" → proceed to implementation below. If "Refine scope" → ask what to change, update proposal, re-confirm.

If "Challenge this first" → invoke /mine.challenge inline against the proposal, read findings, revise proposal, re-present this gate. If "Stop here" → end the skill.

Delight Techniques

Add personality and joy through these methods:

Micro-interactions & Animation

Button delight:

/* Satisfying button press */
.button {
  transition: transform 0.1s, box-shadow 0.1s;
}
.button:active {
  transform: translateY(2px);
  box-shadow: 0 2px 4px rgba(0,0,0,0.2);
}

/* Ripple effect on click */
/* Smooth lift on hover */
.button:hover {
  transform: translateY(-2px);
  transition: transform 0.2s cubic-bezier(0.25, 1, 0.5, 1); /* ease-out-quart */
}

Loading delight:

• Playful loading animations (not just spinners)
• Personality in loading messages (write product-specific ones, not generic AI filler)
• Progress indication with encouraging messages
• Skeleton screens with subtle animations

Success animations:

• Checkmark draw animation
• Confetti burst for major achievements
• Gentle scale + fade for confirmation
• Satisfying sound effects (subtle)

Hover surprises:

• Icons that animate on hover
• Color shifts or glow effects
• Tooltip reveals with personality
• Cursor changes (custom cursors for branded experiences)

Personality in Copy

Note: Playful error copy is appropriate only for non-blocking, easily recoverable errors (404s, empty search results) on playful brands. For serious errors (data loss, permission failures, blocking errors), empathy overrides personality — see /i-clarify.

Playful error messages (non-blocking errors only):

"Error 404"
"This page is playing hide and seek. (And winning)"

"Connection failed"
"Looks like the internet took a coffee break. Want to retry?"

Encouraging empty states:

"No projects"
"Your canvas awaits. Create something amazing."

"No messages"
"Inbox zero! You're crushing it today."

Playful labels & tooltips:

"Delete"
"Send to void" (for playful brand)

"Help"
"Rescue me" (tooltip)

IMPORTANT: Match copy personality to brand. Banks shouldn't be wacky, but they can be warm.

Illustrations & Visual Personality

Custom illustrations:

• Empty state illustrations (not stock icons)
• Error state illustrations (friendly monsters, quirky characters)
• Loading state illustrations (animated characters)
• Success state illustrations (celebrations)

Icon personality:

• Custom icon set matching brand personality
• Animated icons (subtle motion on hover/click)
• Illustrative icons (more detailed than generic)
• Consistent style across all icons

Background effects:

• Subtle particle effects
• Gradient mesh backgrounds
• Geometric patterns
• Parallax depth
• Time-of-day themes (morning vs night)

Satisfying Interactions

Drag and drop delight:

• Lift effect on drag (shadow, scale)
• Snap animation when dropped
• Satisfying placement sound
• Undo toast ("Dropped in wrong place? [Undo]")

Toggle switches:

• Smooth slide with spring physics (zero or near-zero overshoot — e.g., React Spring with high tension, high friction. Visible overshoot/bounce is not permitted.)
• Color transition
• Haptic feedback on mobile
• Optional sound effect

Progress & achievements:

• Streak counters with celebratory milestones
• Progress bars that "celebrate" at 100%
• Badge unlocks with animation
• Playful stats ("You're on fire! 5 days in a row")

Form interactions:

• Input fields that animate on focus
• Checkboxes with a satisfying scale pulse when checked
• Success state that celebrates valid input
• Auto-grow textareas

Sound Design

Subtle audio cues (when appropriate):

• Notification sounds (distinctive but not annoying)
• Success sounds (satisfying "ding")
• Error sounds (empathetic, not harsh)
• Typing sounds for chat/messaging
• Ambient background audio (very subtle)

IMPORTANT:

• Respect system sound settings
• Provide mute option
• Keep volumes quiet (subtle cues, not alarms)
• Don't play on every interaction (sound fatigue is real)

Easter Eggs & Hidden Delights

Discovery rewards:

• Konami code unlocks special theme
• Hidden keyboard shortcuts (Cmd+K for special features)
• Hover reveals on logos or illustrations
• Alt text jokes on images (for screen reader users too!)
• Console messages for developers ("Like what you see? We're hiring!")

Seasonal touches:

• Holiday themes (subtle, tasteful)
• Seasonal color shifts
• Weather-based variations
• Time-based changes (dark at night, light during day)

Contextual personality:

• Different messages based on time of day
• Responses to specific user actions
• Randomized variations (not same every time)
• Progressive reveals with continued use

Loading & Waiting States

Make waiting engaging:

• Interesting loading messages that rotate
• Progress bars with personality
• Mini-games during long loads
• Fun facts or tips while waiting
• Countdown with encouraging messages

Loading messages — write ones specific to your product, not generic AI filler:
- "Crunching your latest numbers..."
- "Syncing with your team's changes..."
- "Preparing your dashboard..."
- "Checking for updates since yesterday..."

WARNING: Avoid cliched loading messages like "Herding pixels", "Teaching robots to dance", "Consulting the magic 8-ball", "Counting backwards from infinity". These are AI-slop copy — instantly recognizable as machine-generated. Write messages that are specific to what your product actually does.

Celebration Moments

Success celebrations:

• Confetti for major milestones
• Animated checkmarks for completions
• Progress bar celebrations at 100%
• "Achievement unlocked" style notifications
• Personalized messages ("You published your 10th article!")

Milestone recognition:

• First-time actions get special treatment
• Streak tracking and celebration
• Progress toward goals
• Anniversary celebrations

Implementation Patterns

Animation libraries:

• Framer Motion (React)
• GSAP (universal)
• Lottie (After Effects animations)
• Canvas confetti (party effects)

Sound libraries:

• Howler.js (audio management)
• Use-sound (React hook)

Physics libraries:

• React Spring (spring physics)
• Popmotion (animation primitives)

IMPORTANT: File size matters. Compress images, optimize animations, lazy load delight features.

NEVER:

• Delay core functionality for delight
• Force users through delightful moments (make skippable)
• Use delight to hide poor UX
• Overdo it (less is more)
• Ignore accessibility (animate responsibly, provide alternatives)
• Make every interaction delightful (special moments should be special)
• Sacrifice performance for delight
• Be inappropriate for context (read the room)

Verify Delight Quality

Test that delight actually delights:

• User reactions: Do users smile? Share screenshots?
• Doesn't annoy: Still pleasant after 100th time?
• Doesn't block: Can users opt out or skip?
• Performant: No jank, no slowdown
• Appropriate: Matches brand and context
• Accessible: Works with reduced motion, screen readers

Remember: Delight is the difference between a tool and an experience. Add personality, surprise users positively, and create moments worth sharing. But always respect usability - delight should enhance, never obstruct.

Completion

After implementation, summarize in conversation:

1. Changes made: List each file changed and what was done
2. Verification: LLM self-check results (anti-pattern scan, consistency check). Note if Playwright was available for visual verification.
3. Suggested next step: Any follow-up skills that would complement this work (e.g., after /i-typeset, suggest /i-polish for a final pass)
