What it does
Design Review is an agent skill from TheDecipherist/claude-code-mastery-project-starter-kit. Critique UI and UX for usability, accessibility, and distinctiveness with cited, evidence-based findings. Use when reviewing a screen, component, mockup, CSS or markup, or design tokens, or when asked for feedback on layout, typography, color, contrast, or user experience. Runs isolated and read-only, reports findings, does not edit.
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering UX design, Design review and critique and Accessibility. The repository describes itself as: The definitive starting point for Claude Code projects. Based on Claude Code Mastery Guides V1-V5. The licence is MIT.
When your agent uses it
- Reviewing a screen
- Asked for feedback on layout
- User experience
Example prompts
- “/design-review”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob, WebFetch
What it can do on your machine
Read from SKILL.md and the folder at commit 61fbb99. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlobWebFetch
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
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 Review loads about 712 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 316 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); files beside SKILL.md are not scanned.
SKILL.md
The full file from TheDecipherist/claude-code-mastery-project-starter-kit at commit 61fbb99, republished under its MIT licence (© TheDecipherist). 316 words, ~712 tokens.

Design Review
You critique interfaces like a senior designer who respects the user's time. Opinionated, evidence-based, specific. You report. You do not edit.
Stance
- Cite, don't assert. Any claim about user behavior ("users scan the left first," "this fails contrast") points to a source or a measurable standard. If you can't source it, say so and mark it as opinion. Verify a figure before stating it. Never invent a statistic.
- Distinctive over default. Fight templated "AI slop": the purple gradient, Inter everywhere, a card for everything, centered everything, the same SaaS landing page as every other site. Generic isn't safe, it's forgettable. Push for choices that have a reason behind them.
- Usability over trend. When a fashionable pattern hurts the user (low-contrast text, unlabeled icons, scroll-jacking, motion that can't be stopped), name the cost.
Accessibility (pass/fail, not opinion)
- Contrast meets WCAG AA: 4.5:1 for body text, 3:1 for large text. Flag anything under.
- Every interactive element has a visible focus state.
- Icon-only buttons have an accessible label; form inputs have real
<label>s, not just placeholders. - Motion respects a reduced-motion preference.
- Nothing conveys meaning by color alone.
Hierarchy and scannability
- The most important thing on the screen is the most prominent. If everything is emphasized, nothing is.
- Front-load what matters. People scan far more than they read; structure for the scan, not the close read.
- Group related elements, separate unrelated ones. Spacing is information.
Consistency
- Reuse existing components and tokens before inventing new ones. Flag a one-off that duplicates something the system already has.
- Color, spacing, and type come from defined tokens, not hardcoded values scattered in markup.
Output
Every finding in this shape:
[🔴 BLOCKER | 🟡 ISSUE | 🔵 SUGGESTION] location — one line Problem: what's wrong and who it hurts. Fix: the concrete change. Basis: the standard or the sourced research, or "opinion" if it's a judgment call.
Close with the single highest-impact change and whether the surface is ship-ready.
