Example session with this skill installed
I have three different blue hex codes for buttons and inconsistent padding everywhere. Help me standardize this into a Tailwind-friendly design system.
- Read your context and instructions
- Compiled the design system builder
- Generated the UI component
Standardized the UI patterns by consolidating hex codes into semantic tokens and defining a consistent spacing scale for Tailwind implementation.
Design System Specification
Token Foundation
| Category | Token | Value | Usage |
|---|---|---|---|
| Color | brand-primary | #2563EB | Default button backgrounds, links |
| Color | brand-hover | #1D4ED8 | Hover states for primary actions |
| Color | brand-muted | #DBEAFE | Background highlights, secondary buttons |
| Spacing | space-sm | 0.5rem (8px) | Internal component padding |
| Spacing | space-md | 1rem (16px) | Standard container padding |
Component Taxonomy
- Button (Actionable): Single responsibility for user triggers. Avoid mixing with Link styles.
- Input (Data Entry): Standardized borders and focus rings using
brand-primary.
Variant Rules
- Primary: Filled background (
brand-primary), white text. - Secondary: Ghost style,
brand-primaryborder and text. - Size:
sm(px-3 py-1),md(px-4 py-2),lg(px-6 py-3).
State Definitions
- Focus:
outline-none ring-2 ring-brand-primary ring-offset-2. - Disabled:
opacity-50 cursor-not-allowedwithgray-300background.
Naming Conventions
- Components: PascalCase (e.g.,
PrimaryButton). - Tokens: kebab-case (e.g.,
--color-brand-primary).
Migration Checklist
- Replace all
#2563EB,#1D4ED8, and#DBEAFEinstances with the new semantic Tailwind classes. - Audit global CSS to remove hardcoded padding values, replacing them with
p-2(sm) orp-4(md). - Wrap existing button logic into a single
Buttoncomponent to enforce variant rules.
Next steps
- Update your
tailwind.config.jswith the new color palette. - Run a grep search for hardcoded hex codes to identify remaining legacy styles.
- Consolidate the two outlier blue shades into the
brand-primarytoken.

What you get
About this skill
Scaling a product often leads to CSS bloat, inconsistent component behavior, and fragmented UI patterns that slow down development. This skill transforms messy UI elements into a lean, professional design system focused on maintainability rather than over-abstraction.
What it does
- Token Foundation creates semantic naming for colors, spacing, and typography to replace hardcoded values.
- Component Taxonomy organizes UI elements into stable, reusable structures with clear responsibilities.
- Variant Rules defines strict boundaries for component variations to prevent prop-drilling and bloat.
- State Definitions ensures focus, error, and disabled states are explicit and accessible.
- Incremental Migration provides a structured checklist to transition existing codebases without breaking changes.
How it works
- Analyze input to identify existing styles, framework constraints, and current UI patterns.
- Translate requirements from plain-language requests into professional technical structures.
- Build the architecture by prioritizing semantic tokens and component stability over decorative work.
- Apply quality gates to ensure accessible patterns, responsive behavior, and bounded variants.
Frameworks & tools
Works with any frontend framework including React, Vue, Tailwind CSS, Svelte, and vanilla CSS/SASS. Designed for design-to-code handoffs and design system engineering.
Why this beats prompting it yourself
Generic prompts often produce shallow style guides that fail to address state management or technical migration. This skill enforces semantic tokenization and strict variant boundaries, preventing the common mistake of creating speculative abstractions that complicate codebases.
Use cases
- Standardizing a legacy React codebase with inconsistent Tailwind utility usage.
- Creating a design token system for a multi-brand project using CSS variables.
- Defining a component library for a startup team to ensure UI consistency.
- Auditing existing UI patterns to consolidate duplicate button or input variants.
Known limitations
Does not perform full-scale app rewrites or invent components without current use cases. Requires existing brand direction or UI samples to be effective.
