Catalogue stub — full skill: szilu/ux-designer-skill

Decision tree

1. Is the full skill already installed? Check whether the skill at this location still has a das: block:

   • Global: grep -q "^das:" ~/.agents/skills/ux-designer-skill/SKILL.md 2>/dev/null && echo "pointer" || echo "installed"
   • Project: grep -q "^das:" .agents/skills/ux-designer-skill/SKILL.md 2>/dev/null && echo "pointer" || echo "installed"
   • No das: block → full skill installed, invoke it and proceed
   • das: block present → go to step 2

2. Detect scope, then install:

   To detect scope:

   [ -e ~/.agents/skills/ux-designer-skill ] && echo "global" || echo "project"
   

   Global (installed with -g):

   npx skills add szilu/ux-designer-skill --skill ux-designer-skill -g -y
   

   Project (installed without -g):

   npx skills add szilu/ux-designer-skill --skill ux-designer-skill -y
   

   Claude Code: send either command as a chat message starting with ! to run it without leaving the conversation.

Invoke after install

What it does

Synthesizes UX guidance from 19 authoritative sources including Nielsen Norman Group, Laws of UX, and others, updated for 2026 best practices. Covers interaction patterns, cognitive load reduction, visual design principles, usability heuristics, and platform-specific conventions (web, mobile, desktop). Useful when you need principled UX rationale grounded in established frameworks rather than generic advice.

When NOT to use

• Code-specific implementation — this skill provides design guidance, not code output
• Brand or visual identity work — use a dedicated brand/creative direction skill
