website rebuild and qa studio
Example session with this skill installed
Rebuild the landing page at https://example-startup.com into a clean Next.js and Tailwind project. Use the live site as the source of truth for all spacing and colors.
- Read your context and instructions
- Compiled the website rebuild
I have completed the rebuild of the landing page from https://example-startup.com into a Next.js 14 project using Tailwind CSS. All styles were extracted from the live computed CSS to ensure fidelity. I have stored the source assets in source/ and the new implementation in rebuild/.
Rebuild and QA Handoff
The project is now a functional Next.js application. I have mapped all legacy CSS classes to their nearest Tailwind equivalents or custom theme extensions to maintain the exact 24px gutter and #0f172a primary brand color observed in the source.
QA Results Summary
| Test ID | Category | Description | Result | Evidence / Notes |
|---|---|---|---|---|
| L-01 | Layout | Desktop 1440 - Hero alignment | verified | Matches computed offsets from source URL. |
| R-01 | Responsive | Hamburger menu trigger at 768px | verified | Verified transition via viewport resize. |
| I-01 | Interaction | Contact form validation | verified | Regex matches source; error state visible. |
| A-01 | Accessibility | ARIA labels on navigation | verified | Preserved from source HTML. |
| P-01 | Performance | LCP under 2.5s | untested | Lab environment not available for timing. |
| AT-01 | Asset | Image integrity | verified | All 12 assets fetched and optimized. |
Failed Items
- None.
Untested Items
P-01 (Performance): I did not run a full Lighthouse or CrUX audit as the local environment does not simulate real-world latency.
- Cross-browser: Testing was performed in a Chromium-based environment; Safari-specific rendering remains untested.

About this skill
The problem
Manual website migrations and rebuilds often suffer from "drift" where styling, interactions, or accessibility features are lost or guessed at. Developers lack a structured way to prove that a rebuild matches the source evidence without tedious, error-prone manual checking.
What it does
- Extracts structure, styles, and assets from live URLs, screenshots, or legacy codebases to create an evidence-based inventory.
- Scaffolds and rebuilds sites using a specified stack while preserving semantic HTML, ARIA attributes, and exact CSS values.
- Reconstructs observed interactive behaviors like modals, dropdowns, and form validations based on source evidence.
- Generates a comprehensive QA Handoff report that classifies every layout, responsive, and accessibility test as verified, failed, blocked, or untested.
Frameworks & tools
Works with React, Next.js, and static HTML/CSS. Uses standard web technologies including semantic HTML5, ARIA, and responsive breakpoints.
Why this beats prompting it yourself
Generic prompts often hallucinate missing details or use placeholders like Lorem Ipsum. This skill enforces a strict evidence-driven workflow, ensuring every hex code and interaction is traced back to a source artifact rather than guessed. It prevents "false greens" in QA by explicitly marking unrun tests as untested instead of claiming success.
Use cases
- Migrating a legacy jQuery or static site to a modern React/Next.js framework.
- Reconstructing a lost website design using only a set of high-fidelity screenshots.
- Auditing a finished rebuild against a live reference to identify layout and accessibility regressions.
- Repairing broken responsive behavior or missing assets on a partially completed migration.
Known limitations
Requires explicit authorization or public domain status for target URLs. Performance metrics like LCP may be marked as untested if a lab environment is not accessible.
Requires authorization for live URL fetching. Performance lab tests and specific mobile hardware checks may be marked 'untested' if the environment lacks specific measurement tools.
