What design-critique does

The skill evaluates interfaces across five areas: initial impression, usability, visual hierarchy, consistency, and accessibility. You supply a screenshot, screen description, or a Figma link. When design tool connectors are enabled, it inspects components, tokens, and layer structures directly.

The output arrives as a formatted Markdown critique. It contains issue tables with severity ratings, contrast checks, positive observations, and three prioritized recommendations. Without active tool connectors, the skill relies entirely on your exported images and supplied text context.

What it helps with

  • audit screen visual hierarchy and reading order
  • check color contrast and touch target sizes
  • verify design system consistency across spacing and typography
  • produce a prioritized list of layout fixes

Example prompts for the agent

  • /design-critique screen.png Focus on the mobile onboarding flow
  • Review this checkout layout mockup and evaluate usability
  • /design-critique Check button contrast and typography hierarchy on this screen

## Usage

```
/design-critique $ARGUMENTS
```

Review the design: @$1

If a Figma URL is provided, pull the design from Figma. If a file is referenced, read it. Otherwise, ask the user to describe or share their design.

## What I Need From You

- **The design**: Figma URL, screenshot, or detailed description
- **Context**: What is this? Who is it for? What stage (exploration, refinement, final)?
- **Focus** (optional): "Focus on mobile" or "Focus on the onboarding flow"

## Critique Framework

### 1. First Impression (2 seconds)
- What draws the eye first? Is that correct?
- What's the emotional reaction?
- Is the purpose immediately clear?

### 2. Usability
- Can the user accomplish their goal?
- Is the navigation intuitive?
- Are interactive elements obvious?
- Are there unnecessary steps?

### 3. Visual Hierarchy
- Is there a clear reading order?
- Are the right elements emphasized?
- Is whitespace used effectively?
- Is typography creating the right hierarchy?

### 4. Consistency
- Does it follow the design system?
- Are spacing, colors, and typography consistent?
- Do similar elements behave similarly?

### 5. Accessibility
- Color contrast ratios
- Touch target sizes
- Text readability
- Alternative text for images

## How to Give Feedback

- **Be specific**: "The CTA competes with the navigation" not "the layout is confusing"
- **Explain why**: Connect feedback to design principles or user needs
- **Suggest alternatives**: Don't just identify problems, propose solutions
- **Acknowledge what works**: Good feedback includes positive observations
- **Match the stage**: Early exploration gets different feedback than final polish

## Output

```markdown
## Design Critique: [Design Name]

### Overall Impression
[1-2 sentence first reaction — what works, what's the biggest opportunity]

### Usability
| Finding | Severity | Recommendation |
|---------|----------|----------------|
| [Issue] | 🔴 Critical / 🟡 Moderate / 🟢 Minor | [Fix] |

### Visual Hierarchy
- **What draws the eye first**: [Element] — [Is this correct?]
- **Reading flow**: [How does the eye move through the layout?]
- **Emphasis**: [Are the right things emphasized?]

### Consistency
| Element | Issue | Recommendation |
|---------|-------|----------------|
| [Typography/spacing/color] | [Inconsistency] | [Fix] |

### Accessibility
- **Color contrast**: [Pass/fail for key text]
- **Touch targets**: [Adequate size?]
- **Text readability**: [Font size, line height]

### What Works Well
- [Positive observation 1]
- [Positive observation 2]

### Priority Recommendations
1. **[Most impactful change]** — [Why and how]
2. **[Second priority]** — [Why and how]
3. **[Third priority]** — [Why and how]
```

## If Connectors Available

If **~~design tool** is connected:
- Pull the design directly from Figma and inspect components, tokens, and layers
- Compare against the existing design system for consistency

If **~~user feedback** is connected:
- Cross-reference design decisions with recent user feedback and support tickets

## Tips

1. **Share the context** — "This is a checkout flow for a B2B SaaS" helps me give relevant feedback.
2. **Specify your stage** — Early exploration gets different feedback than final polish.
3. **Ask me to focus** — "Just look at the navigation" gives you more depth on one area.
