UI UX Pro Max is an AI-powered design intelligence skill that generates production-ready design systems, brand guidelines, and UI component specifications across multiple platforms. It uses 161 reasoning rules and 67 predefined UI styles to analyze project requirements and auto-generate tailored design documentation, token architectures, and implementation guides in seconds—eliminating manual design system creation. Organized as a Claude skill monorepo: .claude/skills/ contains three parallel skill modules (brand, design-system, banner-design), each with SKILL.md descriptors, references/ (documentation CSV and markdown specs), scripts/ (Python and Node validators/generators), and data/ (CSV lookup tables for slides, tokens, typography, layouts). The design-system skill is the heavyweight—it drives core functionality via scripts/generate-slide.py, scripts/generate-tokens.cjs, and structured token definitions in references/token-architecture.md.

Design system leads, product designers, and frontend engineers who need to rapidly establish consistent design systems across web, mobile, and desktop platforms without manually authoring comprehensive brand guidelines and component specifications. Specifically useful for teams adopting shadcn/ui and Tailwind CSS who want AI-assisted design decisions baked into their workflow.

Actively maintained and production-ready. The project released v2.0 with the flagship Design System Generator feature, maintains 161 reasoning rules and 67 UI styles in structured data files, includes Python test infrastructure (pytest fixtures visible in scripts), and publishes an npm CLI package (uipro-cli) with measurable downloads. No obvious abandoned patterns.

Low risk for core capability—uses only Python standard library (no dependency bloat), but integration risk exists around shadcn/ui (requires per-project npm install) and Tailwind CSS version coupling. Single-maintainer risk is moderate (one obvious owner, nextlevelbuilder org). Breaking changes unlikely given v2.0 just shipped; monitor for design rule conflicts as new styles are added beyond the current 67.

Recent focus is on v2.0 launch of the Design System Generator, evidenced by mature slide-*.csv data files for layout logic, typography, color logic, and strategies. Active development on token validation (slide-token-validator.py, html-token-validator.py) and brand-to-token sync (scripts/sync-brand-to-tokens.cjs). The .claude-plugin/ marketplace configuration suggests active distribution as a Claude plugin.

Clone the repository, install Node.js 18+ (for npm), then initialize the skill locally. Python 3.10+ is required for data processing scripts. No explicit build step in README, but run npm install in project root and pip install pytest pytest-cov pytest-mock for dev. Start by reading .claude/skills/design-system/SKILL.md to understand the core workflow and examine scripts/generate-slide.py to see how design rules are applied.

Daily commands: No traditional dev server; this is a skill/library. Execute individual Python scripts directly: python .claude/skills/design-system/scripts/generate-slide.py to generate design slides, python .claude/skills/design-system/scripts/validate-tokens.cjs to validate tokens. For testing: pytest (if test files exist in repo root). For CLI usage: npm install -g uipro-cli then uipro-cli <command> (see marketplace.json for available commands).

Add a New Logo Style

1. Add row to logo style taxonomy (.claude/skills/design/data/logo/styles.csv)
2. Document style characteristics and prompt keywords (.claude/skills/design/references/logo-design.md)
3. Add style-specific color psychology rules (.claude/skills/design/data/logo/colors.csv)
4. Update logo generation script to handle new style variant (.claude/skills/design/scripts/logo/generate.py)
5. Test via logo/core.py helper functions to ensure consistent output (.claude/skills/design/scripts/logo/core.py)

Add a New Design Token (Semantic or Primitive)

1. Define token in the appropriate reference (primitive or semantic) (.claude/skills/design-system/references/primitive-tokens.md)
2. Add token to the design tokens starter template (.claude/skills/design-system/templates/design-tokens-starter.json)
3. Document token usage in semantic tokens or component specs (.claude/skills/design-system/references/component-specs.md)
4. Update token generation script to emit new token (.claude/skills/design-system/scripts/generate-tokens.cjs)
5. Map token to Tailwind CSS config in integration guide (.claude/skills/design-system/references/tailwind-integration.md)

Add a New CIP Deliverable Type

1. Register deliverable in CIP deliverables taxonomy (.claude/skills/design/data/cip/deliverables.csv)
2. Add deliverable to style and industry mappings (.claude/skills/design/data/cip/styles.csv)
3. Document deliverable prompt engineering rules (.claude/skills/design/references/cip-prompt-engineering.md)
4. Update CIP generation script to route new deliverable type (.claude/skills/design/scripts/cip/generate.py)
5. Add HTML rendering template if visual mockup needed (.claude/skills/design/scripts/cip/render-html.py)

Add a New Brand Consistency Rule

1. Document rule in consistency checklist or guideline template (.claude/skills/brand/references/consistency-checklist.md)
2. Add rule to appropriate asset specification file (typography, colors, logo usage) (.claude/skills/brand/references/typography-specifications.md)
3. Optionally create validation script to programmatically check rule (.claude/skills/brand/scripts/validate-asset.cjs)
4. Reference new rule in brand skill definition (.claude/skills/brand/SKILL.md)

1. CSV lookup tables are source-of-truth: modifying slide-*.csv files requires exact column names and no trailing spaces; validators will silently fail if format is off. 2. Python scripts assume UTF-8 file encoding and will crash on non-UTF files in data/ folder. 3. Node scripts expect shadcn/ui to be already initialized in target project (no automatic setup); if missing, token injection silently does nothing. 4. No environment variables visible in file list, but brand color extraction (extract-colors.cjs) likely requires a design tool API key (Figma, Adobe) not documented here. 5. The 161 reasoning rules are implicit in CSV logic—no single file lists them; they emerge from the combine logic in generate-slide.py and CSV conditionals.

• Design System Generation via CSV Reasoning Tables — This repo's core trick: instead of hard-coding design rules, it uses simple CSV lookup tables (slide-strategies.csv, slide-color-logic.csv) that allow non-programmers to add new design scenarios and reasoning paths without touching Python code—understanding this pattern is key to extending the system
• Design Tokens (W3C Format) — The skill outputs design tokens in W3C-aligned JSON structure (primitive, semantic, component layers); you need to understand this taxonomy to work with token-architecture.md and the validators
• Token Injection and Synchronization — The skill must sync tokens from brand guidelines into generated design systems via scripts like inject-brand-context.cjs and sync-brand-to-tokens.cjs; understanding how these scripts avoid conflicts and maintain consistency across multiple data sources is critical
• Semantic vs Primitive Design Tokens — The skill distinguishes between low-level primitive tokens (colors, fonts, sizes) and high-level semantic tokens (primary-action-color, error-border-width); understanding this layer is essential for reading references/semantic-tokens.md and extending token types
• Multi-Platform Design System Scalability — The skill generates systems for web, mobile, and desktop; understanding how tokens translate across platforms (CSS variables, design tool exports, native mobile formats) is key to understanding the architecture of skills/design-system/data/
• CSV-Driven Code Generation — Python scripts like generate-slide.py and HTML validators parse CSV files to drive output generation; this pattern allows data-driven rule addition without recompiling—useful for understanding how to add new design rules or validation paths
• Brand Guideline Asset Organization — The brand skill manages logos, colors, typography, and messaging consistency; understanding references/asset-organization.md and how extract-colors.cjs pulls brand assets is critical for teams integrating existing brand identities

• shadcn-ui/ui — The component library this skill targets; understanding shadcn's structure and component API is essential for token and spec generation
• tailwindlabs/tailwindcss — The CSS framework tokens are generated for; knowledge of Tailwind config structure and theme customization is critical for validator and generator scripts
• storybookjs/storybook — Common companion for design system documentation; many users of this skill would document their generated systems in Storybook
• design-tokens/community-group — W3C specification for design tokens (JSON format, type system); the token-architecture.md in this repo implements a subset of this standard
• nextlevelbuilder/claudekit.cc — Sibling project by same maintainer; likely shares token utilities and design reasoning infrastructure

To work on one of these in Claude Code or Cursor, paste: Implement the "<title>" PR idea from CLAUDE.md, working through the checklist as the task list.

Add Python unit tests for design-system data validation scripts

The repo has multiple Python scripts in .claude/skills/design-system/scripts/ (html-token-validator.py, slide-token-validator.py, slide_search_core.py) but the pytest dependencies are listed with no actual test files present. Adding comprehensive test coverage for these validators would catch regressions in token validation logic and ensure data integrity across the CSV datasets (slide-layouts.csv, slide-color-logic.csv, etc.). This is critical since these scripts process design tokens that feed into the design system.

• [ ] Create tests/ directory structure mirroring .claude/skills/design-system/scripts/
• [ ] Add test_html_token_validator.py with test cases for malformed tokens and edge cases in slide-backgrounds.csv
• [ ] Add test_slide_token_validator.py testing validation against all CSVs in .claude/skills/design-system/data/
• [ ] Add test_slide_search_core.py with fixtures for CSV search functionality
• [ ] Ensure pytest.ini or pyproject.toml configures coverage thresholds
• [ ] Update README with test running instructions (pytest command)

Add Node.js/npm CI workflow for shadcn/ui integration validation

The dependencies document mentions shadcn/ui CLI and Tailwind CSS integration is required, and tailwind-integration.md exists in references, but there is no GitHub Actions workflow validating that the design-tokens-starter.json and component-specs work correctly with shadcn/ui initialization. A CI workflow would catch breaking changes to token architecture and component definitions before they're released.

• [ ] Create .github/workflows/shadcn-ui-validation.yml GitHub Action
• [ ] Workflow should: run npx shadcn-ui@latest init on a test project directory
• [ ] Validate that design-tokens-starter.json can be parsed and imported without errors
• [ ] Run component-specs.md validation against generated shadcn/ui components
• [ ] Test Tailwind CSS configuration generation using generate-tokens.cjs script
• [ ] Add workflow trigger on pushes to .claude/skills/design-system/ paths

Create integration tests for brand asset injection and validation scripts

The brand skill has four scripts (extract-colors.cjs, inject-brand-context.cjs, sync-brand-to-tokens.cjs, validate-asset.cjs) that work together to manage brand consistency, but there are no tests verifying the full pipeline. The brand-guidelines-starter.md template and approval-checklist.md reference material suggest these scripts should enforce brand rules—adding integration tests would ensure color extraction syncs correctly with token injection and that approval workflows function as intended.

• [ ] Create .claude/skills/brand/tests/ directory with sample brand asset fixtures
• [ ] Add test_brand_injection_pipeline.cjs testing extract-colors → sync-brand-to-tokens → validate-asset workflow
• [ ] Create fixtures: sample brand-guideline-starter.md with colors, assets, and expected validation results
• [ ] Test that inject-brand-context.cjs correctly applies approved brand colors from approval-checklist.md
• [ ] Verify validate-asset.cjs rejects assets violating consistency-checklist.md rules
• [ ] Add npm test script to .claude/skills/brand/ and document in brand/SKILL.md

1. Add test coverage for slide generation logic: create tests/test_generate_slide.py with pytest fixtures for the slide-*.csv lookup tables and validate that combinations like 'SaaS + luxury + dark mode' produce expected token outputs. 2. Document the 161 reasoning rules explicitly: audit generate-slide.py and slide-*.csv to extract and list the rules in a new REASONING_RULES.md file organized by category (typography, color, spacing, motion)—currently implicit and hard to discover. 3. Add HTML/CSS validation for generated tokens: extend html-token-validator.py to also validate that generated Tailwind CSS class names actually exist in a standard Tailwind config and warn on custom token usage that won't be understood by downstream tools.

The codebase is a Claude skill for UI/UX design intelligence with moderate security posture. Primary concerns are around input validation in Python and Node.js scripts, CSV data integrity, and HTML template handling. The project lacks visible security controls for data validation and output escaping, which could lead to injection attacks. No critical vulnerabilities detected, but the absence of dependency lock files creates supply chain risks. Recommendations focus on implementing strict input validation, data sanitization, output escaping, and proper dependency management.

• Medium · Python Script Execution without Input Validation — .claude/skills/design-system/scripts/*.py, .claude/skills/design/scripts/**/*.py. Multiple Python scripts in .claude/skills/design-system/scripts/ and .claude/skills/design/scripts/ execute file operations and data processing without visible input sanitization. Scripts like fetch-background.py, generate-slide.py, and search-slides.py could be vulnerable to path traversal or command injection if user inputs are not properly validated before use. Fix: Implement strict input validation and sanitization for all user-provided inputs. Use pathlib.Path for safe file path handling, avoid shell=True in subprocess calls, and validate all CSV/JSON data sources before processing.
• Medium · CSV Data Source Integrity Risk — .claude/skills/design-system/data/*.csv, .claude/skills/design/data/**/*.csv. Multiple CSV files in .claude/skills/design-system/data/ and .claude/skills/design/data/ are used as data sources. These files lack apparent integrity checks or validation mechanisms. Malicious modifications could lead to XSS or other injection attacks if the data is rendered in web contexts without proper escaping. Fix: Implement CSV validation schemas, add file integrity checks (checksums/signatures), and ensure all data is properly escaped when rendered in HTML contexts. Use strict parsing libraries and validate against expected schemas.
• Medium · HTML Template Injection Risk — .claude/skills/design/references/slides-html-template.md, .claude/skills/design-system/templates/. The file .claude/skills/design/references/slides-html-template.md and related template files could potentially contain unsanitized HTML templates. If user-generated content is inserted into these templates without proper escaping, it could lead to XSS vulnerabilities. Fix: Ensure all HTML templates use proper templating engines with auto-escaping enabled. Never allow raw user input in templates. Implement Content Security Policy (CSP) headers and validate all user-provided data before template insertion.
• Low · Node.js Script Execution (.cjs files) — .claude/skills/brand/scripts/*.cjs, .claude/skills/design-system/scripts/*.cjs. CommonJS scripts (.cjs files) in brand and design-system skills directories execute Node.js code without visible security controls. Scripts like extract-colors.cjs, inject-brand-context.cjs, and sync-brand-to-tokens.cjs could have privilege escalation or dependency risks. Fix: Review all .cjs scripts for security best practices. Verify dependencies are from trusted sources. Implement minimal privilege execution contexts. Add script signature verification if distributing these scripts.
• Low · Missing Dependency Lock File — Project root (missing lock files). The provided dependency file shows Python testing dependencies but lacks a lock file (requirements.lock or poetry.lock). There is also no visible package.json lock file mentioned for Node.js dependencies, creating supply chain vulnerability risks. Fix: Implement and commit lock files for all package managers: requirements.txt with pinned versions for Python, and package-lock.json or yarn.lock for Node.js dependencies. Use lock files in CI/CD pipelines.
• Low · Permissive Python Version Specification — Dependencies/Package file content. Dependencies specify 'Python 3.10+' which is very permissive. Untested newer Python versions could introduce compatibility or security issues. Fix: Specify a more constrained Python version range (e.g., >=3.10,<3.13) and test against all supported versions. Update constraints as new versions are released and tested.
