What it does
Design Auditor is an agent skill from borghei/Claude-Skills. 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.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts, reference files and assets (for example `assets/design_audit_template.md`, `assets/sample_audit_data.json` and `references/accessibility_checklist.md`).
It sits in Frontend & Design, covering Accessibility, Responsive design and UI design. The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.
When your agent uses it
- Reviewing designs
- Detecting slop patterns
- Validating WCAG compliance
- Checking design-token adherence
Example prompts
- “/design-auditor”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 4a698e8. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 4 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Design Auditor loads about 1.4k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 63 tokens; SKILL.md has 524 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Design Auditor
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 | Validate CSS against design tokens | python scripts/design_system_validator.py --tokens tokens.json --input src/styles/ |
All tools support --format json|text and --output for file writing.

References
Load the reference that matches the task — keep this file lean and pull detail on demand:
- references/audit-workflows-and-operations.md — quick-start commands, tools-overview table, the three workflows (full audit, slop detection, accessibility/token compliance), grade tables, the 10 design principles, fix-session rules, CI/CD integration, anti-patterns, and troubleshooting. 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.
