## What it does

The command reviews UI that already exists. It reads the target files, works out the framework and styling approach (CSS, Tailwind, styled-components), then goes through four areas: visual design, usability, code quality and render performance. The result is a markdown report that sorts findings by severity — critical, major, minor, suggestion. Each one gets a file location, an explanation of the impact, and a before/after code example.

Expect a conversation first. The command asks what to review: a single component, a page, the whole UI directory, or the latest commit. Then it narrows the focus (visual, usability, code, performance, or all of them), the purpose of the interface, and the target platforms. Questions come one per turn, so you answer each before it moves on.

Reports land in `.ui-design/reviews/` alongside a `review_state.json` that tracks status and issue counts. If the project has `conductor/product.md`, `conductor/tech-stack.md` or `.ui-design/design-system.json`, those get pulled in as context. Without them the review still runs, but the advice stays generic. The argument is optional: pass a file path or a component name, or pass nothing and pick the target from the prompt.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add wshobson/agents
```
In the agent chat (not a shell):
```text
/plugin install ui-design@claude-code-workflows
```

2. **Manually: put the files in place**
- File: `.claude/commands/design-review.md` — Call it with /design-review. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/design-review.md` — Call it with /prompts:design-review. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/design-review.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/design-review.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wshobson/agents/tree/HEAD/plugins/ui-design/commands/design-review.md

## When to use it
- spot inconsistent spacing and alignment in a component
- check text contrast and semantic color usage
- cover loading, error and empty states
- flag unnecessary re-renders and missing memoization
- get a fix list with before/after code samples

## Example prompts
- /ui-design:design-review src/components/UserCard.tsx
- /ui-design:design-review UserCard
- /ui-design:design-review — review everything in src/components for usability

# Design Review

Review existing UI code for design issues, usability problems, and improvement opportunities. Provides actionable recommendations.

## Pre-flight Checks

1. Check if `.ui-design/` directory exists:
   - If not: Create `.ui-design/` directory
   - Create `.ui-design/reviews/` subdirectory for storing review results

2. Load project context if available:
   - Check for `conductor/product.md` for product context
   - Check for `conductor/tech-stack.md` for framework info
   - Check for `.ui-design/design-system.json` for design tokens

## Target Identification

### If argument provided:

- If file path: Validate file exists, read the file
- If component name: Search codebase for matching component files
- If not found: Display error with suggestions

### If no argument:

Ask user to specify target:

```
What would you like me to review?

1. A specific component (provide name or path)
2. A page/route (provide path)
3. The entire UI directory
4. Recent changes (last commit)

Enter number or provide a file path:
```

## Interactive Review Configuration

**CRITICAL RULES:**

- Ask ONE question per turn
- Wait for user response before proceeding
- Gather context to provide relevant feedback

### Q1: Review Focus

```
What aspects should I focus on?

1. Visual design (spacing, alignment, typography, colors)
2. Usability (interaction patterns, accessibility basics)
3. Code quality (patterns, maintainability, reusability)
4. Performance (render optimization, bundle size)
5. Comprehensive (all of the above)

Enter number:
```

### Q2: Design Context (if visual/usability selected)

```
What is this UI's primary purpose?

1. Data display (dashboards, tables, reports)
2. Data entry (forms, wizards, editors)
3. Navigation (menus, sidebars, breadcrumbs)
4. Content consumption (articles, media, feeds)
5. E-commerce (product display, checkout)
6. Other (describe)

Enter number or description:
```

### Q3: Target Platform

```
What platform(s) should I consider?

1. Desktop only
2. Mobile only
3. Responsive (desktop + mobile)
4. All platforms (desktop, tablet, mobile)

Enter number:
```

## State Management

Create/update `.ui-design/reviews/review_state.json`:

```json
{
  "review_id": "{target}_{YYYYMMDD_HHMMSS}",
  "target": "{file_path_or_component}",
  "focus_areas": ["visual", "usability", "code", "performance"],
  "context": "{purpose}",
  "platform": "{platform}",
  "status": "in_progress",
  "started_at": "ISO_TIMESTAMP",
  "issues_found": 0,
  "severity_counts": {
    "critical": 0,
    "major": 0,
    "minor": 0,
    "suggestion": 0
  }
}
```

## Review Execution

### 1. Code Analysis

Read and analyze the target files:

- Parse component structure
- Identify styling approach (CSS, Tailwind, styled-components, etc.)
- Detect framework (React, Vue, Svelte, etc.)
- Note component composition patterns

### 2. Visual Design Review

Check for:

**Spacing & Layout:**

- Inconsistent margins/padding
- Misaligned elements
- Unbalanced whitespace
- Magic numbers vs. design tokens

**Typography:**

- Font size consistency
- Line height appropriateness
- Text contrast ratios
- Font weight usage

**Colors:**

- Color contrast accessibility
- Consistent color usage
- Semantic color application
- Dark mode support (if applicable)

**Visual Hierarchy:**

- Clear primary actions
- Appropriate emphasis
