Design Style Selector

Scan project, identify intent, recommend and deploy the most suitable design system style.

Style Presets

This skill can either:

1. Preserve existing style and extract it into design-system.md (recommended when the project already looks “mature”), or
2. Apply one of 30 preset styles and generate design-system.md.

Style files live in styles/ and are indexed in:

• styles-index.md (ID → filename → theme)

Quick examples of presets:

• 05-saas (B2B tools, dashboards)
• 08-swiss-minimalist (clean hierarchy, corporate)
• 13-neo-brutalism (bold, indie/creative)
• 19-minimal-dark (focus mode, dev tools)

Execution Flow

Step 1: Scan Project

Scan the following files to identify project intent:
- README.md / README
- package.json / pyproject.toml / Cargo.toml
- Existing Claude.md / agent.md / AGENTS.md
- src/ or app/ directory structure
- Existing style files (tailwind.config, globals.css)
- Brand assets (logo, favicon)

Step 2: Analyze Intent

Extract the following information:

• Project Type: SaaS/corporate site/e-commerce/blog/tool/game/...
• Target Users: Developers/enterprises/consumers/children/professionals/...
• Brand Tone: Professional/playful/luxury/minimal/bold/...
• Tech Stack: React/Vue/Next.js/static site/...
• Existing Design Constraints: Current colors/fonts/component libraries

Step 2.5: Existing Style Gate (For existing projects, first determine whether to "preserve style")

Purpose: Avoid forcing a reskin on projects that are "already good-looking/already branded", preventing unnecessary UI rework and cognitive costs.

When a repo already has UI, first do a quick "style maturity" assessment and write out evidence (don't be purely subjective):

Signals of mature style (meeting multiple criteria is sufficient):

• Has clear design tokens: tailwind.config.* has fairly complete color/font/radius/shadow/spacing config, or :root CSS variables form a system
• Component library/component style is consistent (buttons/inputs/cards etc. semantic components have high reuse)
• Layout and spacing are basically consistent across pages (rarely see hardcoded color values/pixels/inline styles)
• Has brand assets (logo, favicon, brand colors) consistently reflected in UI

Signals of immature/inconsistent style:

• Same type of components appear in multiple styles (buttons/forms/cards inconsistent)
• Mixed use of multiple UI libraries/multiple sets of tokens (e.g., multiple Tailwind color schemes + multiple globals.css)
• Lots of scattered hex values/inline styles/random spacing

Gate Output (required):

• If you judge "style is mature": default recommend preserve style and extract to design-system.md (don't force switch to preset)
• If you judge "not mature": proceed to Step 3, recommend from presets and replace

Ask only one question (multiple choice) for user to select strategy:

I've scanned the current project style as [fairly mature / not very unified]. What would you like:

1. Preserve existing style: I'll reverse-extract current UI into design-system.md (document only + light unification, no major reskin)
2. Use this repo's preset: Select one from 30 styles, replace with unified style (requires more significant UI changes)
3. Hybrid: Keep the general direction, but use design tokens/component specs to converge inconsistencies (moderate changes)

If selecting 1): Step 3 doesn't need "recommend 30 styles", instead do "extract and generate design-system.md".

Step 3: Recommend Styles

Based on analysis results, recommend Top 3 best matching styles:

Recommendation #1: [Style Name] ⭐ Best Match
- Match Score: 95%
- Reason: ...
- Fit Points: ...

Recommendation #2: [Style Name]
- Match Score: 85%
- Reason: ...

Recommendation #3: [Style Name]
- Match Score: 75%
- Reason: ...

Step 3.5 (Default when installed): Enrich tokens via tool-ui-ux-pro-max

If tool-ui-ux-pro-max is installed, run it by default to make design-system.md more concrete (palette + typography + UX constraints), instead of relying on a single preset text blob. Only skip if the user explicitly asks to keep the spec minimal, and record the reason.

Recommended searches (pick 1–3 results per category, then synthesize into design-system.md):

# Typography pairing (heading + body + CSS import)
python3 ~/.claude/skills/tool-ui-ux-pro-max/scripts/search.py "<brand tone keywords>" --domain typography

# Color palette (primary/secondary/CTA/background/text/border)
python3 ~/.claude/skills/tool-ui-ux-pro-max/scripts/search.py "<product type keywords>" --domain color

# UX / accessibility guardrails (avoid common “looks good but feels broken” issues)
python3 ~/.claude/skills/tool-ui-ux-pro-max/scripts/search.py "accessibility" --domain ux
python3 ~/.claude/skills/tool-ui-ux-pro-max/scripts/search.py "animation" --domain ux

# Stack-specific implementation constraints (pick the actual project stack)
python3 ~/.claude/skills/tool-ui-ux-pro-max/scripts/search.py "layout responsive" --stack nextjs

Step 4: User Confirmation

• Present recommendation reasons
• Allow user to select or request more options
• Proceed to deployment after confirmation

Step 5: Deploy Design System

1. Copy selected style file to project
2. Rename to design-system.md
3. Placement location:
   - Primary: Project root directory
   - Alternative: docs/ or .cursor/ or .claude/
4. If Claude.md / agent.md exists:
   - Add reference at the top of that file
   - Explain that design-system.md is the unified design constraint

If "preserve existing style" was selected in Step 2.5: "deployment" here is not copying a preset, but writing the tokens, typography rules, component style constraints you extracted from code/styles into design-system.md (also placed at root).

Step 6: Implement UI/UX According to design-system.md (Execute by Default)

The goal of this step is: Make design-system.md actually "live in the UI", not just generate a document and stop.

Execution requirements:

• First produce an executable UI/UX transformation plan (clearly specify which pages/components, scope of changes, acceptance criteria, how to rollback).
• Then implement according to plan (when involving large-scale visual/layout/interaction changes, must have confirmation points).

Recommended implementation order (start from "where it can best align the style"):

1. Design tokens / global style entry: Fonts, colors, spacing, radius, shadows, basic typography (prioritize centralizing in one place, avoid scattering).
2. Component layer: Unify style for buttons, inputs, cards, dialogs and other base components (to be reused by all pages later).
3. Page layer: Prioritize changing "first impression pages" and "core flow pages" to ensure overall consistency.

Note:

• If user explicitly states "don't want to change UI, just want documentation", skip this step and record the reason (e.g., write to run's notes/summary).

Output Format

Scan Report

📁 Project Scan Complete

Project Name: [name]
Project Type: [type]
Tech Stack: [stack]
Target Users: [audience]
Brand Tone: [tone]

Existing Design Assets:
- ✅ tailwind.config.js (has color config)
- ❌ No design system documentation
- ⚠️ Claude.md exists (needs integration)

Deployment Confirmation

✅ Design System Deployed

File: /design-system.md
Style: [selected style]

Completed:
1. Created design-system.md
2. Added reference in Claude.md

Next Steps (execute by default):
- Generate UI/UX transformation plan based on design-system.md (clarify page/component scope and acceptance criteria)
- After user confirmation, redo UI/UX according to plan to implement design specs (avoid "document exists but UI unchanged")

Integration Rules

When Claude.md / agent.md Exists

Add at the top of the file:

## Design System

This project uses a unified design system, see [design-system.md](./design-system.md).

All UI development must follow the design-system.md for:
- Color specifications
- Typography rules
- Component styles
- Spacing system

When No Existing Config Files

Create design-system.md directly in root directory.

Style File Location

All style prompt files are located at: styles/

File naming: [id]-[name].md (e.g., 01-monochrome.md)

Notes

1. Don't overwrite existing files: If design-system.md already exists, ask whether to replace
2. Preserve user choice: Recommendation doesn't mean mandatory, user can choose any style
3. Explain integration method: Clearly explain how to use after deployment
4. Tech stack adaptation: Adjust specific implementation suggestions based on project tech stack
