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.pyvsai_slop_detector.pyvscolor_contrast_checker.pyvsdesign_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.
Tools
| Tool | Purpose | Command |
|---|---|---|
design_scorer.py |
Score 12-category audit findings into three grades | python scripts/design_scorer.py --input findings.json --output report.json --verbose |
ai_slop_detector.py |
Detect AI-generated slop in HTML/CSS | python scripts/ai_slop_detector.py --input page.html --css styles.css --threshold 0.6 |
color_contrast_checker.py |
Check WCAG color contrast (single/batch) | python scripts/color_contrast_checker.py --input color-pairs.json --level AA --suggest-fixes |
design_system_validator.py |

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.
