redesign-existing-projects

Helps improve the look of existing websites and apps. It analyzes interface patterns and suggests design upgrades without needing a full rewrite.

What it does

This tool helps improve the look of existing websites and apps. It analyzes the current design and suggests enhancements to make it more modern and professional, without needing to rewrite the entire code.

When to use it

  • ✓When a website or app looks old or generic.
  • ✓When spacing or colors are unappealing.
  • ✓When mobile versions or loading states are missing.

Example of what to ask your AI

“Improve the design of this website, it looks too basic.”

How to use

The easiest way: copy the message below and paste it into Claude, ChatGPT, Cursor or any AI. It reads the skill and follows the instructions.

Ready-to-paste message

Use this skill to help me: https://github.com/sickn33/agentic-awesome-skills/blob/main/plugins/agentic-awesome-skills-claude/skills/redesign-existing-projects/SKILL.md Read the SKILL.md file at that link and follow its instructions for my task.
How it works

The AI first reads the code to understand how the site was built. Then, it compares the current design with best practices and points out areas for improvement. Finally, it applies the suggested fixes without changing the main structure.

Installation

Easiest way: copy the skill link and paste it into Claude, ChatGPT or Cursor asking it to follow the instructions.

In the terminal (Claude Code, Codex, Cursor), in your project folder:

npx skills add sickn33/agentic-awesome-skills --skill redesign-existing-projects

Or download just the file:

curl -L https://raw.githubusercontent.com/sickn33/agentic-awesome-skills/main/plugins/agentic-awesome-skills-claude/skills/redesign-existing-projects/SKILL.md -o SKILL.md

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.

Example

User request:

Use @redesign-existing-projects for this task: Use when upgrading existing websites or apps by auditing generic UI patterns and applying premium design fixes without rewrites.

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.

FAQ

Will this change how the website works?

No, the focus is solely on the visual aspect. Existing functionality, data, and tests will be preserved.

Do I need to rewrite everything?

No, the goal is to make specific improvements to what already exists, without redoing the project from scratch.

What does 'generic design' mean?

It means a design that looks like many others, lacking personality or special details, such as very common fonts or dull colors.
