What this skill does

# Redesign Skill

## When to Use

- Use when the user asks to redesign, restyle, modernize, polish, or improve an existing website or app UI.
- Use when the task is to audit current frontend code and make targeted visual improvements without changing the product architecture.
- Use when the design feels generic, AI-generated, poorly spaced, visually flat, or missing responsive, interactive, loading, empty, or error states.

## Limitations

- This skill upgrades existing UI but does not authorize framework migrations, information-architecture rewrites, or product-scope expansion by default.
- Preserve working behavior, routing, data flows, accessibility semantics, and tests while making visual changes.
- Validate redesigned screens in the actual app across supported browsers and viewport sizes before considering the work complete.


## How This Works

When applied to an existing project, follow this sequence:

1. **Scan** — Read the codebase. Identify the framework, styling method (Tailwind, vanilla CSS, styled-components, etc.), and current design patterns.
2. **Diagnose** — Run through the audit below. List every generic pattern, weak point, and missing state you find.
3. **Fix** — Apply targeted upgrades working with the existing stack. Do not rewrite from scratch. Improve what's there.

## Design Audit

### Typography

Check for these problems and fix them:

- **Browser default fonts or Inter everywhere.** Replace with a font that has character. Good options: `Geist`, `Outfit`, `Cabinet Grotesk`, `Satoshi`. For editorial/creative projects, pair a serif header with a sans-serif body.
- **Headlines lack presence.** Increase size for display text, tighten letter-spacing, reduce line-height. Headlines should feel heavy and intentional.
- **Body text too wide.** Limit paragraph width to roughly 65 characters. Increase line-height for readability.
- **Only Regular (400) and Bold (700) weights used.** Introduce Medium (500) and SemiBold (600) for more subtle hierarchy.
- **Numbers in proportional font.** Use a monospace font or enable tabular figures (`font-variant-numeric: tabular-nums`) for data-heavy interfaces.
- **Missing letter-spacing adjustments.** Use negative tracking for large headers, positive tracking for small caps or labels.
- **All-caps subheaders everywhere.** Try lowercase italics, sentence case, or small-caps instead.
- **Orphaned words.** Single words sitting alone on the last line. Fix with `text-wrap: balance` or `text-wrap: pretty`.

### Color and Surfaces

- **Pure `#000000` background.** Replace with off-black, dark charcoal, or tinted dark (`#0a0a0a`, `#121212`, or a dark navy).
- **Oversaturated accent colors.** Keep saturation below 80%. Desaturate accents so they blend with neutrals instead of screaming.
- **More than one accent color.** Pick one. Remove the rest. Consistency beats variety.
- **Mixing warm and cool grays.** Stick to one gray family. Tint all grays with a consistent hue (warm or cool, not both).
- **Purple/blue "AI gradient" aesthetic.** This is the most common AI design fingerprint. Replace with neutral bases and a single, considered accent.
- **Generic `box-shadow`.** Tint shadows to match the background hue. Use colored shadows (e.g., dark blue shadow on a blue background) instead of pure black at low opacity.
- **Flat design with zero texture.** Add subtle noise, grain, or micro-patterns to backgrounds. Pure flat vectors feel sterile.
- **Perfectly even gradients.** Break the uniformity with radial gradients, noise overlays, or mesh gradients instead of standard linear 45-degree fades.
- **Inconsistent lighting direction.** Audit all shadows to ensure they suggest a single, consistent light source.
- **Random dark sections in a light mode page (or vice versa).** A single dark-background section breaking an otherwise light page looks like a copy-paste accident. Either commit to a full dark mode or keep a consistent background tone throughout. If contrast is needed, use a slightly darker shade of the same palette — not a sudden jump to `#111` in the middle of a cream page.
- **Empty, flat sections with no visual depth.** Sections that are just text on a plain background feel unfinished. Add high-quality background imagery (blurred, overlaid, or masked), subtle patterns, or ambient gradients. Use reliable placeholder sources like `https://picsum.photos/seed/{name}/1920/1080` when real assets are not available. Experiment with background images behind hero sections, feature blocks, or CTAs — even a subtle full-width photo at low opacity adds presence.

### Layout

- **Everything centered and symmetrical.** Break symmetry with offset margins, mixed aspect ratios, or left-aligned headers over centered content.
- **Three equal card columns as feature row.** This is the most generic AI layout. Replace with a 2-column zig-zag, asymmetric grid, horizontal scroll, or masonry layout.
- **Using `height: 100vh` for full-screen sections.** Replace with `min-height: 100dvh` to prevent layout jumping on mobile browsers (iOS Safari viewport bug).
- **Complex flexbox percentage math.** Replace with CSS Grid for reliable multi-column structures.
- **No max-width container.** Add a container constraint (around 1200-1440px) with auto margins so content doesn't stretch edge-to-edge on wide screens.
- **Cards of equal height forced by flexbox.** Allow variable heights or use masonry when content varies in length.
- **Uniform border-radius on everything.** Vary the radius: tighter on inner elements, softer on containers.
- **No overlap or depth.** Elements sit flat next to each other. Use negative margins to create layering and visual depth.
- **Symmetrical vertical padding.** Top and bottom padding are always identical. Adjust optically — bottom padding often needs to be slightly larger.
- **Dashboard always has a left sidebar.** Try top navigation, a floating command menu, or a collapsible panel instead.
- **Missing whitespace.** Double the spacing. Let the design breathe. Dense layouts work for data dashboards, not for marketing pages.
- **Buttons not bottom-aligned in card groups.** When cards have different content lengths, CTAs end up at random heights. Pin buttons to the bottom of each card so they form a clean horizontal line regardless of content above.
- **Feature lists starting at different vertical positions.** In pricing tables or comparison cards, the list of features should start at the same Y position across all columns. Use consistent spacing above the list or fixed-height title/price blocks.
- **Inconsistent vertical rhythm in side-by-side elements.** When placing cards, columns, or panels next to each other, align shared elements (titles, descriptions, prices, buttons) across all items. Misaligned baselines make the layout look broken.
- **Mathematical alignment that looks optically wrong.** Centering by the math doesn't always look centered to the eye. Icons next to text, play buttons in circles, or text in buttons often need 1-2px optical adjustments to feel right.

### Interactivity and States

- **No hover states on buttons.** Add background shift, slight scale, or translate on hover.
- **No active/pressed feedback.** Add a subtle `scale(0.98)` or `translateY(1px)` on press to simulate a physical click.
- **Instant transitions with zero duration.** Add smooth transitions (200-300ms) to all interactive elements.
- **Missing focus ring.** Ensure visible focus indicators for keyboard navigation. This is an accessibility requirement, not optional.
- **No loading states.** Replace generic circular spinners with skeleton loaders that match the layout shape.
- **No empty states.** An empty dashboard showing nothing is a missed opportunity. Design a composed "getting started" view.
- **No error states.** Add clear, inline error messages for forms. Do not use `window.alert()`.
- **Dead links.** Buttons that link to `#`. Either link to real destinations or visually disable them.
- **No indication of current page in
