Agent Flow — MUST FOLLOW

When the user asks to build a site (or this agent is activated for a new project), ask exactly these questions in a single call, then build the complete site from the answers. Do not over-discuss. Build.

Questions (all in one interaction)

1. "What is the brand name and its purpose in one sentence?" — Free text. Example: "Nura Health — precision longevity medicine driven by biological data."
2. "Choose an aesthetic direction:"
   • A — "Organic Tech" — Biological lab meets luxury magazine. Greens, clay, organic textures.
   • B — "Midnight Luxe" — Dark editorial, gold accents, private-club elegance.
   • C — "Brutalist Signal" — Raw precision, high contrast, information density.
   • D — "Vapor Clinic" — Neon biotech, deep voids, plasma purple.
   • Custom — Describe your own vibe freely. Provide references, colors, mood — I'll build a full design system from scratch.
3. "What are your 3 main value propositions?" — Free text. Short phrases. They will become the Features section cards.
4. "What should visitors do?" — Free text. The primary CTA. Example: "Join the waitlist", "Book a consultation", "Start free trial".

If the user picks Custom: derive a complete design system (palette, typography, image mood, identity label) from their description before proceeding to build. Do NOT use any preset tokens.

Aesthetic Presets

Each preset defines: palette, typography, identity (the overall feel), and imageMood (Unsplash search keywords for hero/texture images).

Preset A — "Organic Tech" (Boutique Clinic)

• Identity: A bridge between a biological research lab and a cutting-edge luxury magazine.

Fixed Design System (NEVER ALTER)

These rules apply to ALL presets. This is what makes the output premium.

Visual Texture

• Implement a global CSS noise overlay using an inline SVG <feTurbulence> filter with 0.05 opacity to eliminate flat digital gradients.
• Use a border system of rounded-[2rem] to rounded-[3rem] for all containers. No sharp corners anywhere.

Micro-Interactions

• All buttons must have a "magnetic" feel: subtle scale(1.03) on hover with cubic-bezier(0.25, 0.46, 0.45, 0.94).
• Buttons use overflow-hidden with a sliding <span> background layer for hover color transitions.
• Links and interactive elements get a translateY(-1px) lift on hover.

Animation Lifecycle

• Use gsap.context() inside useEffect for ALL animations. Return ctx.revert() in cleanup.
• Default easing: power3.out for entrances, power2.inOut for morphs.
• Stagger value: 0.08 for text, 0.15 for cards/containers.

Component Architecture (NEVER ALTER STRUCTURE — only adapt content/colors)

A. NAVBAR — "The Floating Island"

A fixed, pill-shaped container centered horizontally.

• Morphing Logic: Transparent with light text on top of hero. Transitions to bg-[background]/60 backdrop-blur-xl with primary-color text and a subtle border when scroll passes hero. Use IntersectionObserver or ScrollTrigger.
• Contains: Logo (brand name as text), 3-4 nav links, CTA button (accent color).

B. HERO SECTION — "The Opening Scene"

• 100dvh height. Full-bleed background image (fetched from Unsplash matching the preset's imageMood) with a strong primary-to-black gradient overlay (bg-gradient-to-t).
• Layout: Content pushed to the bottom-left third using flex + padding.
• Typography: Large scale contrast following the preset's Hero phrase pattern. First part using the bold sans heading font. Second part using the massive italic serif drama font (3-5x size difference).
• Animation: GSAP staggered fade-up animation (y: 40 → 0, opacity: 0 → 1) for all text parts and CTA.
• CTA button below main title, using accent color.

C. FEATURES — "Interactive Functional Artifacts"

Three cards derived from the user's 3 value propositions. They must look like functional software micro-UIs, not static marketing cards. Each card gets one of these interaction patterns:

Card 1 — "Diagnostic Shuffler": 3 overlapping cards that cycle vertically using array.unshift(array.pop()) logic every 3 seconds with a spring bounce transition (cubic-bezier(0.34, 1.56, 0.64, 1)). Labels derived from user's first value prop (generate 3 sub-labels).

Card 2 — "Telemetry Typewriter": A monospace live text feed that types messages character-by-character related to user's second value prop, with a blinking accent-color cursor. Include a "Live Feed" label with a pulsing dot.

Card 3 — "Cursor Protocol Scheduler": A weekly grid (S M T W T F S) where an animated SVG cursor enters, moves to a day cell, clicks (visual press with scale(0.95)), activates the day (accent color highlight), then moves to a "Save" button before fading out. Labels from user's third value prop.

All cards: bg-[background] surface, subtle border, rounded-[2rem], drop shadow. Each card has a title (sans bold) and a brief description.

D. PHILOSOPHY — "The Manifesto"

• Full-width section using the dark color as background.
• An organic texture image with parallax effect (Unsplash, imageMood keywords) with low opacity behind text.
• Typography: Two contrasting statements. Pattern:
  • "Most [industry] focuses on: [common approach]." — neutral, smaller.
  • "We focus on: [differentiated approach]." — massive, drama serif italic font, keyword in accent color.
• Animation: GSAP SplitText-style reveal (fade-up word-by-word or line-by-line) triggered by ScrollTrigger.

E. PROTOCOL — "Sticky Stacking Archive"

3 full-screen cards that stack on scroll.

• Stacking Interaction: Using GSAP ScrollTrigger with pin: true. As a new card scrolls into view, the card underneath scales to 0.9, gets 20px blur and 0.5 opacity.
• Each card gets a unique canvas/SVG animation:
  1. A slowly spinning geometric pattern (double helix, concentric circles, or gears).
  2. A horizontal scanning laser line moving over a dot/cell grid.
  3. A pulsing waveform (EKG-style SVG path animation using stroke-dashoffset).
• Card content: Step number (monospace), title (heading font), 2-line description. Derive from user's brand purpose.

F. MEMBERSHIP / PRICING

• Pricing grid with three tiers. Card names: "Essential", "Performance", "Enterprise" (adjust to match brand).
• Middle card stands out: Primary-color background with accent-color CTA button. Slightly larger scale or accented border (ring).
• If pricing doesn't apply, convert to a "Get Started" section with a single large CTA.

G. FOOTER

• Deep dark-color background, rounded-t-[4rem].
• Grid layout: Brand name + tagline, navigation columns, legal links.
• "System Operational" status indicator with a pulsing green dot and a monospace label.

Technical Requirements (NEVER ALTER)

• Stack: React 19, Tailwind CSS v3.4.17, GSAP 3 (with ScrollTrigger plugin), Lucide React for icons.
• Fonts: Load via Google Fonts <link> tags in index.html based on selected preset.
• Images: Use real Unsplash URLs. Choose images matching the preset's imageMood. Never use placeholder URLs or images.
• File structure: Single App.jsx file with components defined in-file (or split into components/ if >600 lines). Single index.css for Tailwind properties + noise overlay + custom utilities.
• No placeholders. Every card, every label, every animation must be fully implemented and functional.
• Responsiveness: Mobile-first. Stack cards vertically on mobile. Reduce hero font sizes on mobile. Collapse navbar to minimal version.

Build Sequence

After receiving answers to the 4 questions:

1. Map selected preset to its complete design tokens (palette, fonts, image mood, identity).
2. Generate Hero copy using brand name + purpose + preset's hero phrase pattern.
3. Map the 3 value propositions to the 3 Features card patterns (Shuffler, Typewriter, Scheduler).
4. Generate Philosophy contrast statements from brand purpose.
5. Generate Protocol steps from brand process/methodology.
6. Scaffold: npm create vite@latest, install deps, write all files.
7. Ensure all animations are wired, all interactions work, all images load.

Execution Directive: "Don't build a site; build a digital instrument. Every scroll must be intentional, every animation must have weight and professionalism. Eradicate all generic AI patterns."

Stitch Integration (Optional)

If the user's workspace has the Stitch MCP Server available:

1. After building the site: Use design-md skill to extract the design system into a DESIGN.md file for future consistency.
2. For additional pages: Use enhance-prompt skill to polish prompts before generating with Stitch.
3. For component conversion: Use react-components skill to convert Stitch-generated HTML into modular React components that match the site's design tokens.
