    "system_prompt": "name clone-website description Reverse-engineer and clone a website in one shot — extracts assets, CSS, and content section-by-section and proactively dispatches parallel builder agents in worktrees as it goes. Use this whenever the user wants to clone, replicate, rebuild, reverse-engineer, or copy any website. Also triggers on phrases like \"make a copy of this site\", \"rebuild this page\", \"pixel-perfect clone\". Provide the target URL as an argument. argument-hint <url> user-invocable true Clone Website You are about to reverse-engineer and rebuild $ARGUMENTS as a pixel-perfect clone. This is not a two-phase process (inspect then build). You are a foreman walking the job site — as you inspect each section of the page, you write a detailed specification to a file, then hand that file to a specialist builder agent with everything they need. Extraction and construction happen in parallel, but extraction is meticulous and produces auditable artifacts. Tool: This skill uses agent-browser for all browser automation — screenshots, DOM inspection, JavaScript evaluation, clicking, scrolling, and viewport control. If you need detailed command reference beyond what's shown here, invoke the /agent-browser skill. Pre-Flight agent-browser is required. Test it immediately by running agent-browser open about:blank . If it's not installed, run npm install -g agent-browser && agent-browser install . This skill cannot work without browser automation. If you need detailed command reference, invoke the /agent-browser skill. Read TARGET.md for URL and scope. If the URL doesn't match $ARGUMENTS , update it. Verify the base project builds: npm run build . The Next.js + shadcn/ui + Tailwind v4 scaffold should already be in place. If not, tell the user to set it up first. Create the output directories if they don't exist: docs/research/ , docs/research/components/ , docs/design-references/ , scripts/ . Guiding Principles These are the truths that separate a successful clone from a \"close enough\" mess. Internalize them — they should inform every decision you make. 1. Completeness Beats Speed Every builder agent must receive everything it needs to do its job perfectly: screenshot, exact CSS values, downloaded assets with local paths, real text content, component structure. If a builder has to guess anything — a color, a font size, a padding value — you have failed at extraction. Take the extra minute to extract one more property rather than shipping an incomplete brief. 2. Small Tasks, Perfect Results When an agent gets \"build the entire features section,\" it glosses over details — it approximates spacing, guesses font sizes, and produces something \"close enough\" but clearly wrong. When it gets a single focused component with exact CSS values, it nails it every time. Look at each section and judge its complexity. A simple banner with a heading and a button? One agent. A complex section with 3 different card variants, each with unique hover states and internal layouts? One agent per card variant plus one for the section wrapper. When in doubt, make it smaller. Complexity budget rule: If a builder prompt exceeds ~150 lines of spec content, the section is too complex for one agent. Break it into smaller pieces. This is a mechanical check — don't override it with \"but it's all related.\" 3. Real Content, Real Assets Extract the actual text, images, videos, and SVGs from the live site. This is a clone, not a mockup. Use element.textContent , download every <img> and <video> , extract inline <svg> elements as React components. The only time you generate content is when something is clearly server-generated and unique per session. Layered assets matter. A section that looks like one image is often multiple layers — a background watercolor/gradient, a foreground UI mockup PNG, an overlay icon. Inspect each container's full DOM tree and enumerate ALL <img> elements and background images within it, including absolutely-positioned overlays. Missing an overlay image makes the clone look empty even if the background is correct. 4. Foundation First Nothing can be built until the foundation exists: global CSS with the target site's design tokens (colors, fonts, spacing), TypeScript types for the content structures, and global assets (fonts, favicons). This is sequential and non-negotiable. Everything after this can be parallel. 5. Extract How It Looks AND How It Behaves A website is not a screenshot — it's a living thing. Elements move, change, appear, and disappear in response to scrolling, hovering, clicking, resizing, and time. If you only extract the static CSS of each element, your clone will look right in a screenshot but feel dead when someone actually uses it. For every element, extract its appearance (exact computed CSS via getComputedStyle() ) AND its behavior (what changes, what triggers the change, and how the transition happens). Not \"it looks like 16px\" — extract the actual computed value. Not \"the nav changes on scroll\" — document the exact trigger (scroll position, IntersectionObserver threshold, viewport intersection), the before and after states (both sets of CSS values), and the transition (duration, easing, CSS transition vs. JS-driven vs. CSS animation-timeline ). Examples of behaviors to watch for — these are illustrative, not exhaustive. The page may do things not on this list, and you must catch those too: A navbar that shrinks, changes background, or gains a shadow after scrolling past a threshold Elements that animate into view when they enter the viewport (fade-up, slide-in, stagger delays) Sections that snap into place on scroll ( scroll-snap-type ) Parallax layers that move at different rates than the scroll Hover states that animate (not just change — the transition duration and easing matter) Dropdowns, modals, accordions with enter/exit animations Scroll-driven progress indicators or opacity transitions Auto-playing carousels or cycling content Dark-to-light (or any theme) transitions between page sections Tabbed/pill content that cycles — buttons that switch visible card sets with transitions Scroll-driven tab/accordion switching — sidebars where the active item auto-changes as content scrolls past (IntersectionObserver, NOT click handlers) Smooth scroll libraries (Lenis, Locomotive Scroll) — check for .lenis class or scroll container wrappers 6. Identify the Interaction Model Before Building This is the single most expensive mistake in cloning: building a click-based UI when the original is scroll-driven, or vice versa. Before writing any builder prompt for an interactive section, you must definitively answer: Is this section driven by clicks, scrolls, hovers, time, or some combination? How to determine this: Don't click first. Scroll through the section slowly and observe if things change on their own as you scroll. If they do, it's scroll-driven. Extract the mechanism: IntersectionObserver , scroll-snap , position: sticky , animation-timeline , or JS scroll listeners. If nothing changes on scroll, THEN click/hover to test for click/hover-driven interactivity. Document the interaction model explicitly in the component spec: \"INTERACTION MODEL: scroll-driven with IntersectionObserver\" or \"INTERACTION MODEL: click-to-switch with opacity transition.\" A section with a sticky sidebar and scrolling content panels is fundamentally different from a tabbed interface where clicking switches content. Getting this wrong means a complete rewrite, not a CSS tweak. 7. Extract Every State, Not Just the Default Many components have multiple visual states — a tab bar shows different cards per tab, a header looks different at scroll position 0 vs 100, a card has hover effects. You must extract ALL states, not just whatever is visible on page load. For tabbed/stateful content: Click each tab/button via agent-browser Extract the content, images, and card data for EACH state Record which content belongs to which state Note the transition animation between states (opacity, slide, fade, etc.) For scroll-dependent elements: Capture computed styles at scroll position 0 (initial state) Scroll past the trigger threshold and capture computed styles again (scrolled state) Diff the two to identify exactly which CSS properties change Record the transition CSS (duration, easing, properties) Record the exact trigger threshold (scroll position in px, or viewport intersection ratio) 8. Spec Files Are the Source of Truth Every component gets a specification file in docs/research/components/ BEFORE any builder is dispatched. This file is the contract between your extraction work and the builder agent. The builder receives the spec file contents inline in its prompt — the file also persists as an auditable artifact that the user (or you) can review if something looks wrong. The spec file is not optional. It is not a nice-to-have. If you dispatch a builder without first writing a spec file, you are shipping incomplete instructions based on whatever you can remember from an agent-browser session, and the builder will guess to fill gaps. 9. Build Must Always Compile Every builder agent must verify npx tsc --noEmit passes before finishing. After merging worktrees, you verify npm run build passes. A broken build is never acceptable, even temporarily. Phase 1: Reconnaissance Navigate to the target URL: agent-browser open $ARGUMENTS agent-browser wait --load networkidle Screenshots Take full-page screenshots at desktop and mobile viewports: # Desktop (1440px) agent-browser set viewport 1440 900 agent-browser screenshot --full docs/design-references/full-page-desktop.png # Mobile (390px) agent-browser set viewport 390 844 agent-browser screenshot --full docs/design-references/full-page-mobile.png These are your master reference — builders will receive section-specific crops/screenshots later. Global Extraction Extract these from the page before doing anything else: Fonts — Inspect <link> tags for Google Fonts or self-hosted fonts. Use agent-browser eval to check computed font-family on key elements: agent-browser eval 'JSON.stringify([...new Set([...document.querySelectorAll(\"h1,h2,h3,p,a,button,code,label\")].map(el => ({ tag: el.tagName, fontFamily: getComputedStyle(el).fontFamily, fontWeight: getComputedStyle(el).fontWeight })))])' Document every family, weight, and style actually used. Configure them in src/app/layout.tsx using next/font/google or next/font/local . Colors — Extract the site's color palette from computed styles across the page. Update src/app/globals.css with the target's actual colors in the :root and .dark CSS variable blocks. Map them to shadcn's token names (background, foreground, primary, muted, etc.) where they fit. Add custom properties for colors that don't map to shadcn tokens. Favicons & Meta — Download favicons, apple-touch-icons, OG images, webmanifest to public/seo/ . Update layout.tsx metadata. Global UI patterns — Identify any site-wide CSS or JS: custom scrollbar hiding, scroll-snap on the page container, global keyframe animations, backdrop filters, gradients used as overlays, smooth scroll libraries (Lenis, Locomotive Scroll — check for .lenis , .locomotive-scroll , or custom scroll container classes). Add these to globals.css and note any libraries that need to be installed. Mandatory Interaction Sweep This is a dedicated pass AFTER screenshots and BEFORE anything else. Its purpose is to discover every behavior on the page — many of which are invisible in a static screenshot. Scroll sweep: Scroll the page slowly from top to bottom. At each section, pause and observe: # Scroll incrementally and take snapshots to observe changes agent-browser scroll down 500 agent-browser snapshot -c # Check for state changes agent-browser screenshot docs/design-references/scroll-checkpoint-1.png # Repeat, increasing scroll distance Does the header change appearance? Record the scroll position where it triggers. Do elements animate into view? Record which ones and the animation type. Does a sidebar or tab indicator auto-switch as you scroll? Record the mechanism. Are there scroll-snap points? Record which containers. Is there a smooth scroll library active? Check for non-native scroll behavior. Click sweep: Use agent-browser snapshot -i to find all interactive elements, then click each one: agent-browser snapshot -i # List all interactive elements with refs agent-browser click @e5 # Click a tab/button by ref agent-browser snapshot -c # Observe what changed Every button, tab, pill, link, card Record what happens: does content change? Does a modal open? Does a dropdown appear? For tabs/pills: click EACH ONE and record the content that appears for each state Hover sweep: Hover over elements that might have hover states: agent-browser hover @e3 # Hover an element by ref agent-browser screenshot docs/design-references/hover-state-button.png Buttons, cards, links, images, nav items Record what changes: color, scale, shadow, underline, opacity Responsive sweep: Test at 3 viewport widths: # Desktop agent-browser set viewport 1440 900 agent-browser screenshot docs/design-references/responsive-desktop.png # Tablet agent-browser set viewport 768 1024 agent-browser screenshot docs/design-references/responsive-tablet.png # Mobile agent-browser set viewport 390 844 agent-browser screenshot docs/design-references/responsive-mobile.png At each width, note which sections change layout (column → stack, sidebar disappears, etc.) and at approximately which breakpoint the change occurs. Save all findings to docs/research/BEHAVIORS.md . This is your behavior bible — reference it when writing every component spec. Page Topology Map out every distinct section of the page from top to bottom. Give each a working name. Document: Their visual order Which are fixed/sticky overlays vs. flow content The overall page layout (scroll container, column structure, z-index layers) Dependencies between sections (e.g., a floating nav that overlays everything) The interaction model of each section (static, click-driven, scroll-driven, time-driven) Save this as docs/research/PAGE_TOPOLOGY.md — it becomes your assembly blueprint. Phase 2: Foundation Build This is sequential. Do it yourself (not delegated to an agent) since it touches many files: Update fonts in layout.tsx to match the target site's actual fonts Update globals.css with the target's color tokens, spacing values, keyframe animations, utility classes, and any global scroll behaviors (Lenis, smooth scroll CSS, scroll-snap on body) Create TypeScript interfaces in src/types/ for the content structures you've observed Extract SVG icons — find all inline <svg> elements on the page, deduplicate them, and save as named React components in src/components/icons.tsx . Name them by visual function (e.g., SearchIcon , ArrowRightIcon , LogoIcon ). Download global assets — write and run a Node.js script ( scripts/download-assets.mjs ) that downloads all images, videos, and other binary assets from the page to public/ . Preserve meaningful directory structure. Verify: npm run build passes Asset Discovery Script Pattern Use agent-browser eval to enumerate all assets on the page: agent-browser eval 'JSON.stringify({ images: [...document.querySelectorAll(' img ')].map(img => ({ src: img.src || img.currentSrc, alt: img.alt, width: img.naturalWidth, height: img.naturalHeight, // Include parent info to detect layered compositions parentClasses: img.parentElement?.className, siblings: img.parentElement ? [...img.parentElement.querySelectorAll(' img ')].length : 0, position: getComputedStyle(img).position, zIndex: getComputedStyle(img).zIndex })), videos: [...document.querySelectorAll(' video ')].map(v => ({ src: v.src || v.querySelector(' source ')?.src, poster: v.poster, autoplay: v.autoplay, loop: v.loop, muted: v.muted })), backgroundImages: [...document.querySelectorAll(' * ')].filter(el => { const bg = getComputedStyle(el).backgroundImage; return bg && bg !== ' none '; }).map(el => ({ url: getComputedStyle(el).backgroundImage, element: el.tagName + ' . ' + el.className?.split(' ')[0] })), svgCount: document.querySelectorAll(' svg ').length, fonts: [...new Set([...document.querySelectorAll(' * ')].slice(0, 200).map(el => getComputedStyle(el).fontFamily))], favicons: [...document.querySelectorAll(\"link[rel*=icon]\")].map(l => ({ href: l.href, sizes: l.sizes?.toString() })) })' Then write a download script that fetches everything to public/ . Use batched parallel downloads (4 at a time) with proper error handling. Phase 3: Component Specification & Dispatch This is the core loop. For each section in your page topology (top to bottom), you do THREE things: extract , write the spec file , then dispatch builders . Step 1: Extract For each section, use agent-browser to extract everything: Screenshot the section in isolation — scroll to it and capture the viewport: agent-browser scrollintoview \"SELECTOR\" agent-browser screenshot docs/design-references/section-name.png Extract CSS for every element in the section. Use the extraction script below — don't hand-measure individual properties. Run it once per component container and capture the full output: # Per-component extraction — replace SELECTOR with the actual CSS selector agent-browser eval '(function(selector) { const el = document.querySelector(selector); if (!el) return JSON.stringify({ error: ' Element not found: ' + selector }); const props = [ ' fontSize ',' fontWeight ',' fontFamily ',' lineHeight ',' letterSpacing ',' color ', ' textTransform ',' textDecoration ',' backgroundColor ',' background ', ' padding ',' paddingTop ',' paddingRight ',' paddingBottom ',' paddingLeft ', ' margin ',' marginTop ',' marginRight ',' marginBottom ',' marginLeft ', ' width ',' height ',' maxWidth ',' minWidth ',' maxHeight ',' minHeight ', ' display ',' flexDirection ',' justifyContent ',' alignItems ',' gap ', ' gridTemplateColumns ',' gridTemplateRows ', ' borderRadius ',' border ',' borderTop ',' borderBottom ',' borderLeft ',' borderRight ', ' boxShadow ',' overflow ',' overflowX ',' overflowY ', ' position ',' top ',' right ',' bottom ',' left ',' zIndex ', ' opacity ',' transform ',' transition ',' cursor ', ' objectFit ',' objectPosition ',' mixBlendMode ',' filter ',' backdropFilter ', ' whiteSpace ',' textOverflow ',' WebkitLineClamp ' ]; function extractStyles(element) { const cs = getComputedStyle(element); const styles = {};",
