High-Agency Frontend Skill
When to Use
Use when the user asks to create, improve, or review frontend UI with strong design taste and anti-generic constraints.
Use when React, Next.js, Tailwind, motion, component states, typography, spacing, color, or responsive behavior need senior-level design judgment.
Use when the output must override common LLM UI biases such as centered heroes, purple gradients, card overuse, poor states, and fragile layouts.
Use when building SaaS dashboards, landing pages, marketing sites, or feature sections requiring a "Vercel-core meets Dribbble-clean" aesthetic.
Prerequisites
Framework: React or Next.js project with package.json present.
Styling: Tailwind CSS v3 or v4 installed and configured.
Icons:@phosphor-icons/react or @radix-ui/react-icons installed (or willingness to install).
Motion (optional):framer-motion installed if MOTION_INTENSITY > 3.
Verify dependencies before importing: Check package.json for any 3rd party library before importing it. If missing, output the install command (e.g. npm install package-name) before providing code. Never assume a library exists.
Procedure
1. Set the Active Baseline Configuration
Use these global variables to drive all design decisions in subsequent steps. Adapt dynamically based on explicit user requests in chat prompts; otherwise use these defaults:
Unless the user explicitly specifies a different stack, follow these structural constraints:
Framework & Interactivity: Default to Server Components (RSC).
RSC SAFETY: Global state works ONLY in Client Components. In Next.js, wrap providers in a "use client" component.
INTERACTIVITY ISOLATION: If Motion or Liquid Glass sections are active, extract the interactive UI component as an isolated leaf component with at the very top. Server Components must exclusively render static layouts.
'use client'
State Management: Use local useState/useReducer for isolated UI. Use global state strictly for deep prop-drilling avoidance.
Styling Policy: Use Tailwind CSS (v3/v4) for 90% of styling.
TAILWIND VERSION LOCK: Check package.json first. Do not use v4 syntax in v3 projects.
T4 CONFIG GUARD: For v4, do NOT use tailwindcss plugin in postcss.config.js. Use @tailwindcss/postcss or the Vite plugin.
ANTI-EMOJI POLICY [CRITICAL]: NEVER use emojis in code, markup, text content, or alt text. Replace symbols with high-quality icons (Radix, Phosphor) or clean SVG primitives. Emojis are BANNED.
Responsiveness & Spacing:
Standardize breakpoints (sm, md, lg, xl).
Contain page layouts using max-w-[1400px] mx-auto or max-w-7xl.
Viewport Stability [CRITICAL]: NEVER use h-screen for full-height Hero sections. ALWAYS use min-h-[100dvh] to prevent layout jumping on mobile browsers (iOS Safari).
Grid over Flex-Math: NEVER use complex flexbox percentage math (w-[calc(33%-1rem)]). ALWAYS use CSS Grid (grid grid-cols-1 md:grid-cols-3 gap-6).
Icons: Use exactly @phosphor-icons/react or @radix-ui/react-icons as import paths (check installed version). Standardize strokeWidth globally (e.g., exclusively 1.5 or 2.0).
Proactively construct premium interfaces using these engineered rules:
Rule 1: Deterministic Typography
Display/Headlines: Default to text-4xl md:text-6xl tracking-tighter leading-none.
ANTI-SLOP: Discourage Inter for "Premium" or "Creative" vibes. Force unique character using Geist, Outfit, Cabinet Grotesk, or Satoshi.
TECHNICAL UI RULE: Serif fonts are strictly BANNED for Dashboard/Software UIs. Use exclusively high-end Sans-Serif pairings (Geist + Geist Mono or Satoshi + JetBrains Mono).
Body/Paragraphs: Default to text-base text-gray-600 leading-relaxed max-w-[65ch].
Rule 2: Color Calibration
Max 1 Accent Color. Saturation < 80%.
THE LILA BAN: The "AI Purple/Blue" aesthetic is strictly BANNED. No purple button glows, no neon gradients. Use absolute neutral bases (Zinc/Slate) with high-contrast, singular accents (e.g. Emerald, Electric Blue, or Deep Rose).
COLOR CONSISTENCY: Stick to one palette for the entire output. Do not fluctuate between warm and cool grays within the same project.
Rule 3: Layout Diversification
ANTI-CENTER BIAS: Centered Hero/H1 sections are strictly BANNED when DESIGN_VARIANCE > 4. Force "Split Screen" (50/50), "Left Aligned content / Right Aligned asset", or "Asymmetric White-space" structures.
Rule 4: Materiality, Shadows, and "Anti-Card Overuse"
DASHBOARD HARDENING: For VISUAL_DENSITY > 7, generic card containers are strictly BANNED. Use logic-grouping via border-t, divide-y, or purely negative space. Data metrics should breathe without being boxed in unless elevation (z-index) is functionally required.
Use cards ONLY when elevation communicates hierarchy. When a shadow is used, tint it to the background hue.
Rule 5: Interactive UI States
Mandatory Generation: You MUST implement full interaction cycles:
Systematically implement these high-end coding concepts as baseline:
"Liquid Glass" Refraction: When glassmorphism is needed, go beyond backdrop-blur. Add a 1px inner border (border-white/10) and a subtle inner shadow (shadow-[inset_0_1px_0_rgba(255,255,255,0.1)]) to simulate physical edge refraction.
Magnetic Micro-physics (If MOTION_INTENSITY > 5): Implement buttons that pull slightly toward the mouse cursor. CRITICAL: NEVER use React useState for magnetic hover or continuous animations. Use EXCLUSIVELY Framer Motion's useMotionValue and useTransform outside the React render cycle to prevent performance collapse on mobile.
Perpetual Micro-Interactions (When MOTION_INTENSITY > 5): Embed continuous, infinite micro-animations (Pulse, Typewriter, Float, Shimmer, Carousel) in standard components (avatars, status dots, backgrounds). Apply premium Spring Physics (type: "spring", stiffness: 100, damping: 20) to all interactive elements—no linear easing.
Layout Transitions: Always utilize Framer Motion's layout and layoutId props for smooth re-ordering, resizing, and shared element transitions across state changes.
Staggered Orchestration: Do not mount lists or grids instantly. Use staggerChildren (Framer) or CSS cascade (animation-delay: calc(var(--index) * 100ms)) to create sequential waterfall reveals. CRITICAL: For staggerChildren, the Parent (variants) and Children MUST reside in the identical Client Component tree. If data is fetched asynchronously, pass the data as props into a centralized Parent Motion wrapper.
5. Apply Performance Guardrails
DOM Cost: Apply grain/noise filters exclusively to fixed, pointer-event-none pseudo-elements (e.g., fixed inset-0 z-50 pointer-events-none) and NEVER to scrolling containers to prevent continuous GPU repaints and mobile performance degradation.
Hardware Acceleration: Never animate top, left, width, or height. Animate exclusively via transform and opacity.
Z-Index Restraint: NEVER spam arbitrary z-50 or z-10 unprompted. Use z-indexes strictly for systemic layer contexts (Sticky Navbars, Modals, Overlays).
4-7 (Offset): Use margin-top: -2rem overlapping, varied image aspect ratios (e.g., 4:3 next to 16:9), left-aligned headers over center-aligned data.
8-10 (Asymmetric): Masonry layouts, CSS Grid with fractional units (e.g., grid-template-columns: 2fr 1fr 1fr), massive empty zones (padding-left: 20vw).
MOBILE OVERRIDE: For levels 4-10, any asymmetric layout above md: MUST aggressively fall back to a strict, single-column layout (w-full, px-4, py-8) on viewports < 768px to prevent horizontal scrolling and layout breakage.
MOTION_INTENSITY (Level 1-10)
1-3 (Static): No automatic animations. CSS :hover and :active states only.
4-7 (Fluid CSS): Use transition: all 0.3s cubic-bezier(0.16, 1, 0.3, 1). Use animation-delay cascades for load-ins. Focus strictly on transform and opacity. Use will-change: transform sparingly.
8-10 (Advanced Choreography): Complex scroll-triggered reveals or parallax. Use Framer Motion hooks. NEVER use window.addEventListener('scroll').
VISUAL_DENSITY (Level 1-10)
1-3 (Art Gallery Mode): Lots of white space. Huge section gaps. Everything feels very expensive and clean.
4-7 (Daily App Mode): Normal spacing for standard web apps.
8-10 (Cockpit Mode): Tiny paddings. No card boxes; just 1px lines to separate data. Everything is packed. Mandatory: Use Monospace (font-mono) for all numbers.
7. Apply the "Motion-Engine" Bento Paradigm (For SaaS Dashboards)
When generating modern SaaS dashboards or feature sections, use the following "Bento 2.0" architecture:
A. Core Design Philosophy
Aesthetic: High-end, minimal, and functional.
Palette: Background in #f9fafb. Cards are pure white (#ffffff) with a 1px border of border-slate-200/50.
Surfaces: Use rounded-[2.5rem] for all major containers. Apply a "diffusion shadow" (e.g., shadow-[0_20px_40px_-15px_rgba(0,0,0,0.05)]) to create depth without clutter.
Typography: Strict Geist, Satoshi, or Cabinet Grotesk font stack. Use subtle tracking (tracking-tight) for headers.
Labels: Titles and descriptions must be placed outside and below the cards to maintain a clean, gallery-style presentation.
Pixel-Perfection: Use generous p-8 or p-10 padding inside cards.
B. The Animation Engine Specs (Perpetual Motion)
Spring Physics: No linear easing. Use type: "spring", stiffness: 100, damping: 20 for a premium, weighty feel.
Layout Transitions: Heavily utilize the layout and layoutId props to ensure smooth re-ordering, resizing, and shared element state transitions.
Infinite Loops: Every card must have an "Active State" that loops infinitely (Pulse, Typewriter, Float, or Carousel) to ensure the dashboard feels "alive".
Performance: Wrap dynamic lists in <AnimatePresence> and optimize for 60fps. PERFORMANCE CRITICAL: Any perpetual motion or infinite loop MUST be memoized (React.memo) and completely isolated in its own microscopic Client Component. Never trigger re-renders in the parent layout.
C. The 5-Card Archetypes (Micro-Animation Specs)
Implement these specific micro-animations when constructing Bento grids (e.g., Row 1: 3 cols | Row 2: 2 cols split 70/30):
The Intelligent List: A vertical stack of items with an infinite auto-sorting loop. Items swap positions using layoutId, simulating an AI prioritizing tasks in real-time.
The Command Input: A search/AI bar with a multi-step Typewriter Effect. It cycles through complex prompts, including a blinking cursor and a "processing" state with a shimmering loading gradient.
The Live Status: A scheduling interface with "breathing" status indicators. Include a pop-up notification badge that emerges with an "Overshoot" spring effect, stays for 3 seconds, and vanishes.
The Wide Data Stream: A horizontal "Infinite Carousel" of data cards or metrics. Ensure the loop is seamless (using x: ["0%", "-100%"]) with a speed that feels effortless.
The Contextual UI (Focus Mode): A document view that animates a staggered highlight of a text block, followed by a "Float-in" of a floating action toolbar with micro-icons.
8. Draw from the Creative Arsenal (High-End Inspiration)
Do not default to generic UI. Pull from this library of advanced concepts to ensure the output is visually striking and memorable. When appropriate, leverage GSAP (ScrollTrigger/Parallax) for complex scrolltelling or ThreeJS/WebGL for 3D/Canvas animations, rather than basic CSS motion. CRITICAL: Never mix GSAP/ThreeJS with Framer Motion in the same component tree. Default to Framer Motion for UI/Bento interactions. Use GSAP/ThreeJS EXCLUSIVELY for isolated full-page scrolltelling or canvas backgrounds, wrapped in strict useEffect cleanup blocks.
The Standard Hero Paradigm: Stop doing centered text over a dark image. Try asymmetric Hero sections: Text cleanly aligned to the left or right. The background should feature a high-quality, relevant image with a subtle stylistic fade (darkening or lightening gracefully into the background color depending on if it is Light or Dark mode).
Navigation & Menus: Mac OS Dock Magnification, Magnetic Button, Gooey Menu, Dynamic Island, Contextual Radial Menu, Floating Speed Dial, Mega Menu Reveal.
Evaluate code against this matrix before outputting. This is the last filter applied to logic:
Is global state used appropriately to avoid deep prop-drilling rather than arbitrarily?
Is mobile layout collapse (w-full, px-4, max-w-7xl mx-auto) guaranteed for high-variance designs?
Do full-height sections safely use min-h-[100dvh] instead of the bugged h-screen?
Do useEffect animations contain strict cleanup functions?
Are empty, loading, and error states provided?
Are cards omitted in favor of spacing where possible?
Did you strictly isolate CPU-heavy perpetual animations in their own Client Components?
Pitfalls
Forbidden AI Tells (Strictly Avoid Unless Explicitly Requested)
Visual & CSS
NO Neon/Outer Glows: Do not use default box-shadow glows or auto-glows. Use inner borders or subtle tinted shadows.
NO Pure Black: Never use #000000. Use Off-Black, Zinc-950, or Charcoal.
NO Oversaturated Accents: Desaturate accents to blend elegantly with neutrals.
NO Excessive Gradient Text: Do not use text-fill gradients for large headers.
NO Custom Mouse Cursors: They are outdated and ruin performance/accessibility.
Typography
NO Inter Font: Banned. Use Geist, Outfit, Cabinet Grotesk, or Satoshi.
NO Oversized H1s: The first heading should not scream. Control hierarchy with weight and color, not just massive scale.
Serif Constraints: Use Serif fonts ONLY for creative/editorial designs. NEVER use Serif on clean Dashboards.
Layout & Spacing
Align & Space Perfectly: Ensure padding and margins are mathematically perfect. Avoid floating elements with awkward gaps.
NO 3-Column Card Layouts: The generic "3 equal cards horizontally" feature row is BANNED. Use a 2-column Zig-Zag, asymmetric grid, or horizontal scrolling approach instead.
Content & Data (The "Jane Doe" Effect)
NO Generic Names: "John Doe", "Sarah Chan", or "Jack Su" are banned. Use highly creative, realistic-sounding names.
NO Generic Avatars: DO NOT use standard SVG "egg" or Lucide user icons for avatars. Use creative, believable photo placeholders or specific styling.
NO Fake Numbers: Avoid predictable outputs like 99.99%, 50%, or basic phone numbers (1234567). Use organic, messy data (47.2%, +1 (312) 847-1928).
NO Filler Words: Avoid AI copywriting clichés like "Elevate", "Seamless", "Unleash", or "Next-Gen". Use concrete verbs.
External Resources & Components
NO Broken Unsplash Links: Do not use Unsplash. Use absolute, reliable placeholders like https://picsum.photos/seed/{random_string}/800/600 or SVG UI Avatars.
shadcn/ui Customization: You may use shadcn/ui, but NEVER in its generic default state. You MUST customize the radii, colors, and shadows to match the high-end project aesthetic.
Production-Ready Cleanliness: Code must be extremely clean, visually striking, memorable, and meticulously refined in every detail.
Common Technical Pitfalls
Tailwind v3/v4 mismatch: Using v4 syntax in a v3 project. Always check package.json first.
RSC state leakage: Using global state in Server Components. Wrap providers in "use client" components.
Magnetic hover with useState: Using React useState for continuous animations causes performance collapse on mobile. Use Framer Motion's useMotionValue and useTransform exclusively.
GSAP + Framer Motion mixing: Never mix GSAP/ThreeJS with Framer Motion in the same component tree. Use Framer Motion for UI/Bento, GSAP/ThreeJS for isolated full-page scrolltelling or canvas backgrounds only.
staggerChildren across component boundaries: Parent variants and Children MUST reside in the identical Client Component tree. Pass async data as props into a centralized Parent Motion wrapper.
Grain/noise on scrolling containers: Causes continuous GPU repaints. Apply only to fixed, pointer-event-none pseudo-elements.
Animating layout properties: Never animate top, left, width, or height. Use transform and opacity exclusively.
Verification
Before delivering the final output, verify each of the following:
Dependency check: Confirm all imported packages exist in package.json. If any are missing, provide the install command first.
# Check for a specific package
Select-String -Path package.json -Pattern "framer-motion"
Tailwind version check: Confirm Tailwind version and use matching syntax.
