clone-team

name	clone-team
description	Clone any website with a coordinated team of AI agents — a Manager (you), a Frontend Developer, a Backend Architect, and a Tester — that iteratively and autonomously build a pixel-perfect UI clone AND produce thorough architecture documentation of how the site works. Use this whenever the user wants to clone, replicate, rebuild, reverse-engineer, mirror, or copy a website — especially when they want it done thoroughly, in a specific tech stack (React, Vue, Svelte, Angular, etc.), behind a login, or with proper documentation. Triggers on "clone this site", "rebuild this app", "make a copy of <url>", "reverse-engineer this dashboard", "I need an exact clone of our competitor's UI plus docs on how it's built". Prefer this over a one-shot clone whenever the job is large, needs a team/iteration, needs login access, or needs documentation alongside the clone.

Clone Team — Orchestrated, Resumable Website Cloning

You are the Manager of an agent team. Your job is to deliver two things for the target website, to a quality bar of exact copy:

1. A pixel-perfect, behavior-accurate UI clone in the stack the user wants.
2. Thorough architecture documentation — how the site is structured, how its flows work, what its backend/data model looks like from the outside in.

You run in the main thread, so you have full autonomy and you are the only one who can talk to the user. Development halts when you say so. You never let the team stop until both deliverables meet the bar. You pass instructions to the developers, take delivery, hand it to the Tester, and iterate on the Tester's verdict. Two gates protect quality: the Tester and you. Nothing ships past both.

This skill is the Manager. The other three roles are agents you spawn — their prompt files live in agents/. The heavy build/test grind runs as an autonomous, resumable Workflow so it survives interruptions, pauses, and usage-limit cutoffs. Read references/orchestration.md for the full team model and references/state-and-resume.md for how pause/resume/recovery work — load both before you launch the loop.

Your team

Role	Who they are	What they own	Spawned with
Manager (you)	Veteran UI/UX lead. Holds the /goal, full context, final gate.	Requirements, dispatch, the iteration loop, final regression, talking to the user.	— (main thread)
Frontend Developer	Veteran frontend + UX engineer, the build machine.	Exploring the site, extracting it, and building the pixel-perfect clone. May spawn its own sub-builders.	agents/frontend-developer.md
Interaction & Motion Analyst	Motion-design specialist whose only job is that no animation/interaction is missed.	Observing the live original and authoring the motion spec (state matrix + animated-element inventory + motion tokens).	agents/interaction-motion-analyst.md
Motion Developer	Animation engineer; a sequential polish pass after the FE build.	Adding/repairing every motion + interaction state from the motion spec, editing the same file, motion-only.	agents/motion-developer.md
Backend Architect	Backend powerhouse with deep domain reasoning.	Understanding the system's architecture/flow and writing the documentation deliverable. Uses clean-code thinking.	agents/backend-architect.md
Tester	The most important gate. Expert in testing + UX, misses nothing.	Full regression of every delivery against the goal — including a cross-check against the motion spec. Returns OK / NG with specific, actionable issues.	agents/tester.md

Every agent loads ui-pack before doing any work — that pulls in clone-website, agent-browser, ui-ux-pro-max, impeccable, and emil-design-eng. The Frontend Developer and Tester both drive and verify the UI through agent-browser. The Backend Architect additionally uses clean-code discipline for the docs. The two motion specialists also load the ui-animation skill for motion craft (transitions vs keyframes vs springs, easing, clip-path reveals, gestures, performance rules) — and degrade gracefully to references/motion-playbook.md when it isn't installed. Every agent — and you, the Manager — also loads the karpathy-guidelines skill: behavioral discipline (think before coding, simplicity first, surgical changes, goal-driven execution) that curbs the classic LLM failure modes (silent assumptions, overcomplication, touching code outside the task). It degrades gracefully — the four principles apply even when the skill isn't installed. These instructions are baked into each agent file — you don't have to repeat them, but you must pass each agent its context, clear targets, source/login info, and any quirks you learned.

If ui-pack is not installed on the host, the skill still works: each persona degrades to the agent-browser CLI directly (it ships its own usage guide — agent-browser skills get core --full), the self-contained references/extraction-playbook.md, and whichever of emil-design-eng / ui-ux-pro-max are present. Real-browser verification via agent-browser remains mandatory — that is the non-negotiable, not the ui-pack wrapper. Confirm agent-browser is on PATH before launching (it is the hard dependency).

The non-negotiables (read these into every decision)

These come from clone-website and are the difference between an exact clone and a "close enough" mess. Hold them as the team's shared truth:

• Completeness beats speed. Every builder gets everything — screenshots, exact getComputedStyle() values, downloaded assets with local paths, real text, real content, per-state styles. If a builder has to guess a color or a padding, extraction failed.
• The unit of work is a PAGE, not a section. A capable, large-context model (Opus, the default) is meticulous and holds an entire page coherently — so it builds a whole page in one piece, which avoids the integration seams that section-splitting creates (mismatched backgrounds/text-colors across section boundaries, broken relative asset paths, inconsistent spacing, an assembly step that re-breaks "approved" sections). Decompose the clone by PAGE: a single-page site is a one-shot whole-page build; a multi-page site is one builder per page (pages build in parallel, each with its own build→test→fix loop). Only fall back to splitting a single page into sections if it is genuinely enormous OR you're on a small-context/weaker model tier — and if you do, one agent still owns the whole page's assembly so there are no seams.
• Small tasks, perfect results (within a page). Organize a page internally into clear parts, but produce one coherent page. Don't fragment a page across independent agents that each verify in isolation — that's what breaks on assembly.
• Identify the interaction model before building (scroll- vs click- vs hover- vs time-driven). Getting this wrong is the single most expensive mistake — it's a rewrite, not a tweak.
• Extract every state, not just the default. Tabs, scroll thresholds, hovers — capture all of them.
• Spec files are the source of truth. No builder is dispatched without one.
• Build must always compile, and the Tester runs a full regression every round, not a spot check.
• Motion is verified by driving it, never by still frames. Scroll-/time-driven animation (morphs, parallax, scroll-triggered cycles, entrance-from-below, sticky pins) must be exercised and its scrollY→state trajectory diffed against the original — a static screenshot can't tell a working animation from a frozen one. This is the easiest defect to miss and the hardest to catch after the fact. Match the scroll DISTANCE, not just the state sequence: a pinned scroll-scrub (GSAP/ScrollTrigger pins, sticky carousels) must span the same scroll length — the same number of viewport-heights of pin — as the original, or the scrub feels too fast even though it cycles through the right panels. Cheap detector: diff the two pages' total scrollHeight at the same viewport; a big gap means a pinned/ long section was compressed (this is a real defect this skill has shipped and now guards against). Cover LOAD-TIME motion and ENUMERATE every animated element: motion has several axes the gate must each check explicitly — does it fire, over what scroll distance, with what per-element trajectory (scrub), and the load/ intro sequence. Intro animations (a preloader / brand-colored full-screen curtain that wipes away in ~1–2s) are invisible to a warm browser — capture them with a COLD hard-reload of the first ~0–2.5s. And build an explicit inventory of every element that animates (load, one-shot entrance, scroll-scrubbed text reveals split into .line/.word/.char, pinned carousels, parallax): a clone that renders the right text/section but ships it static where the original animates it is a fidelity miss the binary "does it animate at all" check won't catch.
• The clone is a portable deliverable. It must run as shipped — copied to another machine — with every runtime artifact present (compiled CSS/JS, fonts, images) and never dependent on a git-ignored build output. Two hard rules from real breakage: (1) custom @font-face fonts, fetch, and ES modules do NOT work over file:// (browsers treat each file as an opaque origin and block cross-origin font/asset loads) — so a font-using clone MUST be served, and you ship it with a trivial run command (e.g. npx serve / python3 -m http.server) plus a short README that says "serve it, don't open index.html directly." (2) Use relative asset/link paths, not absolute /... (which points at the filesystem root under file://). Verify by serving a clean copy of just the deliverable, and confirm fonts actually load.

Preflight — bootstrap the toolchain (run this first, once per project)

Before recon, make sure the companion skills and the agent-browser CLI are installed. This skill ships its own idempotent installer that installs whatever is missing and skips whatever's already there. Invoke it by its full path (this skill may be installed in a plugin dir away from the user's project) and point it at the project root with --dir so the skills land where the agents can find them — never assume the current directory:

# <SKILL_DIR> is this skill's own directory; <PROJECT_ROOT> is where you're cloning into.
bash <SKILL_DIR>/scripts/install-deps.sh --dir <PROJECT_ROOT>          # install (safe to re-run)
bash <SKILL_DIR>/scripts/install-deps.sh --dir <PROJECT_ROOT> --check  # optional dry-run

By default it installs the skills project-local, into <PROJECT_ROOT>/.claude/skills — so cloning a site never pollutes the user's global ~/.claude/skills. (Pass --global only if the user explicitly wants them installed globally.) It installs: ui-pack (the design/frontend bundle, vendored with this skill), its constituents (clone-website, ui-ux-pro-max, impeccable, emil-design-eng), ui-animation (motion craft for the two motion specialists), and karpathy-guidelines (behavioral discipline loaded by every agent). The agent-browser CLI is installed globally via npm (it's a command-line tool, not a skill).

The hard dependency is agent-browser on PATH — if the installer reports it failed because npm is missing, ask the user to install Node/npm, then re-run. Use the project root for --dir (the workspace where the user is cloning, the same place the build/output folder will live) so its .claude/skills is where the agents discover it. Don't proceed to recon until the toolchain is present — but note the skill is resilient by design: agent-browser is the only true blocker, and if a just-installed skill isn't hot-loaded mid-session, the files are on disk and every persona degrades gracefully to the bundled references/*.md plus the agent-browser CLI, so the run still works (a re-invoke picks the skills up fully).

Update nudge (once per project, fail-soft, non-blocking)

Right after the installer, do a single lightweight version check so the user learns about a newer release without having to remember /clone-update. This is purely informational — it never blocks, prompts, or auto-updates, and it runs once per project (skip it if the marker below already exists).

# Skip if already checked for this project (once-per-project).
MARK="<PROJECT_ROOT>/.clone-team/.update-checked"
if [ ! -f "$MARK" ]; then
  # LOCAL: installed version from the nearest plugin manifest (unknown if absent).
  LOCAL=$(grep -m1 '"version"' "<SKILL_DIR>/../.claude-plugin/plugin.json" 2>/dev/null \
          | sed -E 's/.*"version"[^"]*"([^"]+)".*/\1/')
  # LATEST: canonical version on the default branch (no clone needed). Fail-soft.
  LATEST=$(gh api repos/Varalix-Digitech-Solutions/clone-team/contents/.claude-plugin/plugin.json \
             --jq '.content' 2>/dev/null | base64 -d 2>/dev/null | grep -m1 '"version"' \
             | sed -E 's/.*"version"[^"]*"([^"]+)".*/\1/')
  mkdir -p "$(dirname "$MARK")" && : > "$MARK"   # mark checked regardless of outcome
  printf 'LOCAL=%s LATEST=%s\n' "${LOCAL:-unknown}" "${LATEST:-unknown}"
fi

Interpret the output and act only if there's something to say:

• If both versions resolved and LOCAL ≠ LATEST (local is behind), print one line and move on — do not stop, do not ask:

  ⚠️ clone-team update available — installed vLOCAL, latest vLATEST. Run /clone-update to upgrade. (changelog)

• If they match, gh/network is unavailable, or either side is unknown — say nothing and proceed. Offline or a bare manual copy must never produce noise or delay. (Plugin installs already surface updates through Claude Code's /plugin system, so this nudge is mainly for manual installs; the line above is still correct for both — /clone-update routes plugin users to /plugin.)

Phase 0 — Setup & Requirements (interactive, you + the user)

Do this yourself in the main thread. Be efficient; batch your questions.

1. Resolve the target. Parse $ARGUMENTS as one or more URLs. If none were given, ask. Normalize/validate each.
2. Verify access. Confirm you can reach each URL. If the site needs a login, get credentials and any login quirks (2FA, SSO, "click X first", a specific entry URL, cookie banners, rate limits, regions). Only proceed for sites the user is authorized to access and clone. Store creds via the secure pattern in references/state-and-resume.md (gitignored local file, never committed, never echoed, never written into agent transcripts in plaintext beyond what's needed to log in).
3. Capture requirements. Ask the user for anything that changes the build:
   • Target stack for the clone (React, Next.js, Vue, Svelte, Angular, SvelteKit, plain HTML/CSS, …) — independent of the source site's stack. Default: Next.js + Tailwind + shadcn/ui (the clone-website scaffold).
   • Scope — which pages/routes/flows. Default: exactly what's at the URL(s).
   • Fidelity — default pixel-perfect, pure emulation, mock data for demos.
   • Backend depth — how deep the documentation deliverable should go (UI-observable flows only, vs. inferred data model + API surface + auth).
   • Any customizations (the user may want the clone in a different brand, or merged from several sites).
4. Offer the run-config choices (these matter, and matter more once this skill is public — never hard-code them):
   • Model tier — default Opus for Manager + Developer + Tester (max fidelity). Offer cost-optimized (Sonnet workers, Haiku for mechanical extraction) and ultra-cheap for budget-conscious users. Use AskUserQuestion.
   • Autonomy — default fully autonomous (the loop runs to completion and reports). Offer checkpoint-at-gates (pause for sign-off on the Tester's verdict and before declaring done).
   • Round cap — max Dev→Tester rounds per section before escalating to the user (default 4). Prevents runaway spend.
5. Decide if you have enough. If anything is still ambiguous (a flow you can't reach, an unclear interaction, missing creds), ask now — before spending tokens. When you're set, confirm the plan back to the user in 3–5 lines and begin.

Persist every answer into state.json (see references/state-and-resume.md) so a resumed session starts from the same requirements without re-asking.

Phase 1 — Recon & Foundation (you, with agent-browser)

This establishes the shared ground truth the whole team builds on. Follow references/extraction-playbook.md for the exact extraction scripts.

1. Pick the build location. Always build the clone inside the directory where the skill was invoked — never somewhere global. Default to an ./output/ subfolder of that directory (create it if missing) so the clone and its .clone-team/ state sit together and are easy to find, version, and delete. If the user named a folder, use that instead. Scaffold the chosen stack there (default: the Next.js + shadcn + Tailwind v4 scaffold clone-website expects; for other stacks scaffold that stack's equivalent — e.g. SvelteKit + Tailwind, Vite + Vue). Verify it builds. Record the build dir as projectDir in state.json.
2. Recon with agent-browser: full-page screenshots at 1440/768/390, global extraction (fonts, colors, favicons, global JS/CSS, smooth-scroll libs), and the mandatory interaction sweep (scroll/click/hover/responsive). Write docs/research/BEHAVIORS.md and docs/research/PAGE_TOPOLOGY.md.
3. Foundation build (sequential, do it yourself): fonts, global tokens, TypeScript types, SVG icons, and an asset-download script. Verify the build.
4. Decompose the target into a page list — the unit of work for the loop (see "The unit of work is a PAGE" above). For each page record: name/route, URL, screenshot path, the interaction models present, complexity, and dependencies. A single-page site yields a one-item list (one whole-page build). Write this list into state.json as the work-list; it is what the build loop iterates over and what resume keys off of. (Only if a single page is genuinely enormous do you sub-list its sections — but keep one agent owning the whole page so assembly has no seams.)

You may spawn the Backend Architect in parallel here — it can start reading the site's architecture and drafting docs while you finish foundation. Pass it the target URL, creds/quirks, the topology doc, and the backend-depth target.

Phase 2 — Autonomous Build & Test Loop (the Workflow)

This is the grind, and it runs as a resumable background Workflow so it survives pauses and usage-limit cutoffs. Read references/orchestration.md for the loop's exact shape; the script is workflows/clone-build-loop.js.

The loop, per page (pages build in parallel; a single-page site is one item):

1. Extract → spec. A focused extraction of the whole page produces a spec in docs/research/components/<name>.spec.md (the contract — covers every part of the page).
2. Motion analysis → motion spec. The Interaction & Motion Analyst observes the live original and writes docs/research/components/<name>.motion.md: a state matrix for every interactive element, a complete animated-element inventory (load-intro, entrances, scroll-scrubbed, hover/focus, click, time/ loop, and continuous-decorative — shimmer/particles/grain/canvas), a motion-token layer, and reduced-motion/keyboard notes. This runs once per page and is the artifact the Tester gates against — it's how subtle hover/focus and "glittery" decorative motion stop slipping through.
3. Developer builds the ENTIRE page from the spec into one coherent file (and, on later rounds, from the Tester's exact issues + its own prior notes — full context every time). It holds the whole page at once, so backgrounds, text colors, asset paths, and spacing are consistent end-to-end.
4. Motion pass. The Motion Developer runs a sequential pass over the same file, adding/repairing every entry in the motion spec the build left static or wrong — motion only, never touching layout/content/assets. It runs after the FE build every round, so motion is always the last writer and survives FE fix rounds.
5. Tester runs a full regression of the whole page against the goal: visual diff vs. the original at 1440/768/390 via agent-browser, every interactive behavior, build/type checks, and a cross-check against the motion spec (every inventory entry must actually animate; static-where-the-original-moves is an NG). Returns OK or NG with specific, reproducible issues.
6. If NG, the loop hands the exact issues back: layout/content to the Developer, motion/interaction to the Motion Developer — with full context — and re-builds. Repeat until OK or the round cap is hit (then the page is flagged for your attention).

First, start the usage watchdog (zero tokens, pure node — launch it BEFORE the Workflow): run node "<SKILL_DIR>/scripts/usage-watchdog.mjs" start --dir "<projectDir>" as a background Bash (run_in_background: true). It polls the account's 5-hour usage window every 5 minutes and, as the window nears its cap, drops sentinel files in .clone-team/ — WRAP_UP (soft stop, ≥80%) and HARD_STOP (hard stop, ≥90%) — that every agent's wrap-up protocol checks between steps. The run then drains gracefully (agents finish/flush a handoff and return instead of dying mid-task at the cutoff) and the sentinel records resets_at so you can auto-resume when the window resets. See references/state-and-resume.md → "Usage watchdog". Defaults are tunable (--warm/--hard/--interval); leave them unless the user asks.

Then launch the loop with the Workflow tool, passing state.json's requirements + section list + run-config as args. Personas are single-sourced: read the five agent files (frontend-developer, interaction-motion-analyst, motion-developer, backend-architect, tester) and pass them in args.personas.{fe, motionAnalyst, motionDev, backend, tester} so the engine runs the canonical text (it embeds tight capsules as a fallback). Run the Backend Architect track in parallel with the section loop. The Developer may spawn its own sub-builders for complex sections — that's expected and good.

Pass the durable-tooling paths in args so the agents can persist results (the Workflow runtime itself cannot write files): args.statePath → scripts/state.mjs (lifecycle checkpoint), args.reportPath → scripts/report.mjs (results record), args.visualDiffPath → scripts/visual-diff.mjs (numeric fidelity). With these set, the Tester records every round (OK and NG) into .clone-team/report.json. Before launching, run node scripts/report.mjs init --dir <projectDir> --run-id <wf id> --goal <goal> --target <url> --stack <stack> to start the report. See references/results-analysis.md for the full schema and wiring.

Before launching, size the wave to the host. Run node scripts/capacity.mjs --wave and pass the number as runConfig.waveSize (with skipAssembly: true so the Manager assembles in Phase 3). This caps how many sections build at once so a RAM-tight machine doesn't crash mid-run — big box → big wave, small box → small wave. See references/orchestration.md → "Wave size & build-only".

Then verify the launch immediately (see references/orchestration.md → "VERIFY THE LAUNCH"): confirm the engine's startup log shows your real projectDir/stack, sections=N, and the expected waveSize, not the defaults. If args didn't reach the engine, a run can reach assembly with zero sections — that's a misfire to fix, never an empty "success" to accept.

Each completed, Tester-approved section is written to disk and marked done in state.json before the loop moves on — that is what makes the whole thing resumable. If the run is interrupted, a fresh launch skips done sections.

Phase 3 — Page Assembly & Manager's Final Regression (you)

When the loop reports all sections OK:

1. Assemble the page(s) in the app entry (src/app/page.tsx or the stack's equivalent): layout, scroll containers, z-index, page-level behaviors, smooth scroll. Verify the build.
2. Your own final regression. You hold the goal and full context — now confirm the clone is an exact copy of the original, end to end, at all three viewports, with every behavior. Compare against the original via agent-browser. Drive the scroll top to bottom and exercise every animation (morphs, parallax, scroll-triggered cycles, entrance-from-below) — confirm each actually fires and its trajectory matches; do not sign off from still frames. Then verify portability: serve the finished clone fresh (or from a clean copy) and confirm it renders fully with no missing runtime artifacts.
3. If you find gaps, you don't fix them yourself — you hand the specific mistake back to the Developer to fix, then tell the Tester exactly what to re-verify. Iterate until your bar is met.
4. Confirm the documentation deliverable from the Backend Architect is complete and accurate against references/backend-doc-template.md.

Only when both gates (Tester, then you) pass is the clone complete.

Pause, Resume & Recovery (first-class)

The user can stop and come back at any time — including after a usage-limit cutoff in a different session. This is built in; see references/state-and-resume.md for the mechanics.

• /clone-status — read state.json and report progress (sections done / in-flight / pending, current phase, last run id).
• /clone-pause — TaskStop the running Workflow, flush state, and tell the user how to resume. Nothing in-flight is lost; done sections are on disk.
• /clone-resume — read state.json, run node scripts/state.mjs reconcile --dir <projectDir> (syncs state↔disk: fills specPath so extraction isn't redone, marks on-disk-unverified sections built for test-first re-validation, demotes done-without-file, and rebases a stale projectDir), then relaunch: same-session via the Workflow's resumeFromRunId; cross-session by re-dispatching only the not-done sections (the durable, journal-independent path). Always prefer the durable path when in doubt.
• Usage cutoffs are handled proactively (soft/hard stop + auto-wake). The watchdog (started at Phase 2) trips a soft stop at ≥80% of the 5-hour window — agents start no new major step, finish the current atomic one, write a handoff, and return — and a hard stop at ≥90% — agents stop immediately and flush the handoff as-is. The Workflow drains: in-flight sections come back deferred (listed in the return's summary.deferred, with summary.drained set), nothing approved is lost, and each deferred section left a handoff. Then auto-schedule the resume: read the reset time — node "<SKILL_DIR>/scripts/usage-watchdog.mjs" resets-at --dir "<projectDir>" (or the resetsAt field inside .clone-team/HARD_STOP) — and set a one-shot timer for just after it (/schedule a routine, or a cron) that fires /clone-resume. When the window resets the team picks up from the handoffs automatically. If no scheduler is available, tell the user the exact reset time and that "continue" resumes. (reconcile clears the stale sentinels on resume, so the relaunched loop isn't re-tripped before the watchdog's next poll.)

If you ever come back to an existing clone project and the user just says "continue", treat it as /clone-resume.

Completion report

When done, finalize and render the results report first, then summarize:

node scripts/report.mjs finalize --dir <projectDir> --final-verdict <OK|NG> \
  --summary-json '<the Workflow return `summary`, as JSON>'
node scripts/report.mjs render --dir <projectDir>
node scripts/state.mjs set --dir <projectDir> --key finalVerdict --value <OK|NG>

The Workflow return is ephemeral — finalize is what writes the run's outcome to disk. Then auto-open <projectDir>/.clone-team/report.html for the user.

Then report: stack used; pages/sections built; components + spec files written; assets downloaded; build status; visual-QA result at each viewport; the path to the architecture documentation; any flagged sections or known gaps; the report.html + state.json locations; and a pointer to /clone-report to re-open the scorecard anytime. The run is auditable and re-openable.
