ui-clone-skills

ui-clone-skills is a plugin for Claude Code from voidmatcha/ui-clone-skills. Its manifest loads nothing; the 4 skills, 6 agents, 6 hooks it bundles cost 833 tokens per session together, scanned A, original, Apache-2.0.

A toolkit for analysing, rebuilding, and checking animated web pages from a live URL. It can study motion, create a React and Tailwind clone, compare an existing implementation, or export raw findings.

In plain words
What is it for?
Use it to decode page motion, clone a site, capture reference behavior, extract implementation details, or verify layout and animation using image-difference and motion-comparison checks.
Why use it?
It gives the agent a repeatable way to investigate page layout and animation behavior, including motion settings found in JavaScript, and measure differences against the reference.

Security

Grade A, and why

ui-clone-skills scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

{
  "name": "ui-clone-skills",
  "version": "0.7.38",
  "description": "Motion forensics for the animated web. Four jobs against a live URL: decode (analyse motion + build, no code), clone (URL → React + Tailwind), verify (AE/SSIM + motion-parity score vs. an existing impl), extract (raw JSON dump). Extracts real CSS and animation params (GSAP / Framer Motion / Lenis / anime.js) directly from JS bundles, then verifies with AE/SSIM diff — no vision tokens, no screenshot input. Three underlying skills: ui-reverse-engineering (decode/clone/verify/extract entry points, supports Webflow IX2 / Next.js / Tailwind v4), ui-capture (reference screenshots, scroll evidence, transitions), visual-debug (AE/SSIM diff + computed-style mismatch diagnosis). Shared hooks and gates enforce extraction and verification before code generation.",

What ships with it

7 files beside plugin.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
