Design Auditor

SkillMedia

Audit UI/UX designs for quality, AI-generated slop, and accessibility. Use when reviewing designs, detecting slop patterns, validating WCAG compliance, checking design-token adherence, or reviewing responsive design across breakpoints.

What this skill tells your AI

The instructions your AI receives, as published by borghei/claude-skills in engineering/design-auditor/SKILL.md and read by ahel’s review.

Performs systematic 12-category UI/UX audits, detects AI-generated slop patterns, validates WCAG color contrast, and checks design system token compliance. Produces three independent grades: Design (A-F), AI Slop (A-F), and Accessibility (A-F).

Core Capabilities

  • Full design audit — score 12 weighted categories in five passes into a Design grade with prioritized recommendations and baseline comparison.
  • AI slop detection — flag visual, copy, and structural slop in HTML/CSS with confidence scores and per-finding remediation.
  • Accessibility audit — WCAG color-contrast checking (AA/AAA) with closest-compliant-color suggestions.
  • Design-system compliance — detect hardcoded colors, spacing, fonts, radii, shadows, z-indices, and transitions that deviate from tokens; report compliance percentage.
  • Three independent grades — Design (weighted aggregate), AI Slop (inverted), Accessibility (WCAG), each A–F.
  • Operating system — 10 design principles, fix-session rules with a risk accumulator, and CI/CD gating.

When to Use

  • Reviewing a UI/UX design for quality, originality, and accessibility.
  • Detecting AI-generated slop patterns in HTML/CSS.
  • Validating WCAG color contrast or design-token adherence.
  • Gating deployments or PRs on minimum compliance scores.

Clarify First

Before running the audit, confirm these inputs. If any is unknown or vague, ASK — do not assume:

  • Audit type — full design score, AI-slop detection, contrast check, or token compliance (selects design_scorer.py vs ai_slop_detector.py vs color_contrast_checker.py vs design_system_validator.py)
  • Input artifacts — the findings JSON, HTML/CSS, color pairs, or design-token file (the input each tool requires)
  • Conformance level / threshold — WCAG AA vs AAA, slop confidence threshold, and the minimum passing grade (sets --level, --threshold, and the gate)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

References

Load the reference that matches the task — keep this file lean and pull detail on demand:

Read when running an audit end to end.
  • references/design_audit_methodology.md — systematic audit approach, heuristic evaluation, Gestalt principles, critique frameworks, and anti-patterns. Read when designing the evaluation pass.
  • references/ai_slop_patterns.md — comprehensive catalog of AI-generated UI patterns and remediation guidance. Read when judging originality.
  • references/accessibility_checklist.md — full WCAG 2.1 Level A/AA/AAA checklist organized by POUR with testing methodology and fixes. Read when auditing accessibility.

Scope & Limitations

Covers static design quality, AI-slop, WCAG contrast, and design-token compliance auditing for web UI (HTML/CSS). Does not run live browsers, render-test layouts, or replace manual usability research. Accessibility findings are never "Low" priority; WCAG AA is the floor.
