AI Skills for UX/UI Design: Claude, Codex & Beyond
Summary of the video “Las Skills que debes conocer para diseño UX/UI con Claude y Codex” by Mokkapp.
Modern UX designers must bridge user needs, AI capabilities, and business goals. Five key AI skills—Impeccable, Weli, custom research agents, Taste Skill, and PRD generation—automate design research, enforce visual standards, detect usability problems, and produce production-ready documentation in minutes.
The Evolved UX Designer Role
UX Design Now Bridges Three Worlds
Modern UX designers connect user research, AI possibilities, and business objectives. The role extends beyond wireframes and prototypes to orchestrating how AI interprets design needs and automates product development tasks.
Impeccable: Visual Design Language for AI
Teaching AI Professional Design Vocabulary
Impeccable is a design skill that gives AI agents understanding of visual hierarchy, contrast, rhythm, composition, and aesthetic constraints—concepts that AI models struggle with despite being able to code components. It includes a design MD file with visual principles that agents reuse throughout development.
Solves AI-Generated Code Aesthetics Problem
AI typically generates functional but visually unappealing code. Impeccable ensures generated code is both functional and visually appealing, acting as an integrated art director within coding environments like Cursor, Claude Code, and Codex.
Weli: 50+ Methodological Skills
Encapsulated Design Frameworks for AI
Weli is a collection of over 50 skills that embed methodologies from recognized books and frameworks, allowing AI agents to automatically apply proven design and UX approaches. The design and UX category includes UX Heuristics, Design of Everyday Things, Refactoring UI, and Lean UX.
UX Heuristics: AI as Usability Auditor
Based on Jacob Nielsen and Steve Krug's historical work, UX Heuristics teaches AI to detect usability problems before real users encounter them. It transforms AI into a UX auditor capable of identifying the same issues a usability expert would catch before product launch.
Five-Skill Research Collection: From Data to PRD
Complete Research Pipeline Compressed to Minutes
A custom five-skill collection automates the entire UI research process, producing a complete PRD with real data and revealing conclusions. Each skill targets a specific research phase, from market analysis through product viability assessment.
Market Research Skill
Identifies competitors and reveals how they are positioned in the market, providing competitive landscape context.
User Analysis Skill
Extracts real user conversations from Reddit, forums, reviews, and communities to build data-driven proto-personas and define jobs-to-be-done—what users actually try to achieve with similar products.
Product & Experience Skill
Analyzes how market-dominating products are designed, providing design patterns and best practices from successful competitors.
Viability Analysis Skill
Examines how the sector makes money, assessing the financial and business viability of the proposed product.
PRD Generation Skill
Consolidates all research documentation into a complete, production-ready PRD that can be delivered to product and development teams.
Taste Skill: Eliminating AI Slop
Visual Sense Framework for AI Designers
Taste Skill is an open-source framework that transforms AI agents into designers with visual judgment. Instead of generating generic interfaces, it forces AI to understand the design brief, choose a coherent design system, and apply visual consistency rules.
Ensures Intention, Hierarchy, and Style
Taste Skill solves the problem of AI-generated interfaces lacking visual intention and coherence by enforcing design system adherence and visual consistency throughout the generated interface.
