Automated Component Improvement

Changes

  • Description rewrite: Replaced generic description with a delegation-trigger prompt that specifies when to invoke the agent (screenshots, mockups, CSS, HTML, design tokens, AI chat interfaces)
  • WebFetch tool added: Enables the agent to look up live NN Group articles and other design resources during reviews
  • WCAG 2.2 compliance coverage: Added four new AA criteria — Focus Not Obscured (SC 2.4.11), Dragging Alternatives (SC 2.5.7), Accessible Authentication (SC 3.3.8), Redundant Entry (SC 3.3.7); updated touch target guidance to cite SC 2.5.8
  • AI Interface Patterns section: New section covering input UX, output UX, refinement UX, transparency/trust patterns, and loading states for AI-powered products (2024-2026)
  • INP awareness: Added Interaction to Next Paint checklist items (<200ms p75 target) and JS-driven hover animation anti-pattern to Trendy But Bad list
  • Thumb zone update: Added grip-variability note from Hoober follow-up research (2020+); design for variable grip patterns, not a single static zone
  • CSS example trimming: Removed ~25% of prompt size by replacing verbatim font loading, animation, and background CSS blocks with concise instructions; preserved the CSS variables block as it illustrates a naming convention

Research Summary

The ui-ux-designer is the #3 most popular agent (13,696 downloads, 637/week). Research identified gaps in delegation triggering (too narrow a description), outdated WCAG coverage (2.1 only), missing AI-specific UX patterns (increasingly requested), lack of Core Web Vitals/INP awareness, and oversized prompt from verbatim CSS examples the model generates naturally.

Validation

  • component-reviewer: PASSED
    • name: ui-ux-designer (valid kebab-case)
    • description: present (delegation-trigger format)
    • tools: Read, Grep, Glob, WebFetch (all valid)
    • model: opus
    • No hardcoded secrets
    • No absolute paths
    • Correct category: agents/development-team
    • Attribution comment block preserved (Madina Gbotoe, CC BY 4.0)

Summary by cubic

Enhances the ui-ux-designer component so it triggers at the right times and delivers current, research-backed reviews. Adds live lookups, WCAG 2.2 AA coverage, AI UI patterns, INP/perf checks, and trims prompt size.

  • New Features

    • Rewrote description into clear triggers; added WebFetch for live design research.
    • Expanded compliance and performance checks: WCAG 2.2 AA (SC 2.4.11, 2.5.7, 3.3.7, 3.3.8, 2.5.8), INP <200ms p75, lazy-load modal/drawer; flagged JS hover animation anti-pattern.
    • Added AI UI patterns (input, output, refinement, transparency, loading); updated thumb-zone guidance; trimmed verbose CSS, and require working CSS/HTML with exact values.
  • Migration

    • Area: components (cli-tool/components/). No new components. Regenerate catalog (docs/components.json). No new env vars or secrets.

Written for commit 46a585f. Summary will update on new commits.

P2: This SC 3.3.8 guidance is inaccurate: WCAG does not categorically ban CAPTCHAs, and SC 3.3.8 is scoped to authentication of existing users (not signup). Update the line to match the actual requirement about providing a non-cognitive alternative path.</violation>
