## What it does

The skill evaluates rendered interfaces across four dimensions: clickability signals, state visibility, CTA clarity, and action discoverability. For each dimension, the agent provides a neutral observation, explains what is broken, suggests a concrete fix, and rates the severity as `pass`, `minor issue`, or `major issue`.

It checks whether touch targets meet the 44×44px minimum on mobile and flags desktop patterns that fail on touch devices, such as contextual actions hidden behind hover states. It also catches suppressed focus rings with `outline: none`, ghost buttons that lack border contrast, and competing filled CTAs that confuse navigation.

Use this tool strictly for reviewing existing screens; when sizing and positioning targets in new work, use `fitts-law` instead.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill critique-affordance -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/critique-affordance/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/critique-affordance/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill critique-affordance -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/critique-affordance/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill critique-affordance -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/critique-affordance/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Owl-Listener/designer-skills critique-affordance
```

2. **Manually: put the files in place**
- File: `.github/skills/critique-affordance/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill critique-affordance -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Owl-Listener/designer-skills --path visual-critique/skills/critique-affordance
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/critique-affordance/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill critique-affordance -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Owl-Listener/designer-skills/tree/HEAD/visual-critique/skills/critique-affordance/SKILL.md

## When to use it
- spot interactive controls disguised as static elements
- flag hover-only actions inaccessible on touch displays
- identify suppressed focus outlines and missing control states
- resolve visual conflicts between multiple primary CTAs

## Example prompts
- Review this rendered screen using critique-affordance to check button clickability
- Audit state visibility and CTA hierarchy on this checkout form with critique-affordance
- Check whether actions on this dashboard are discoverable using critique-affordance

# Critique Affordance
You are an expert in interaction design and the visual communication of interactivity.
## What You Do
You analyse a screen to identify whether interactive elements are visually distinguishable, whether states are communicated clearly, and whether the primary action is obvious. You flag affordance failures and propose specific fixes.
## Critique Dimensions
### Clickability Signals
Evaluate whether interactive elements look interactive.
- Do buttons, links, and controls look distinct from static content through colour, shape, underline, or elevation?
- Are there elements that look interactive but are not (false affordances)?
- Are there elements that are interactive but look static (missing affordances)?
- Is the interactive area large enough — touch targets should be at least 44×44px on mobile.
### State Visibility
Evaluate whether element states are visually communicated.
- Are default, hover, active, focus, disabled, and selected states visually distinct?
- Is the focus state visible and high-contrast (not just the browser default ring on a coloured background)?
- Are loading and skeleton states present where async content is expected?
- Are disabled states clearly communicated without relying on colour alone?
### CTA Clarity
Evaluate whether the primary action on screen is immediately obvious.
- Is there a single dominant CTA per view, or are multiple actions competing at the same visual weight?
- Does the primary CTA use filled/solid style while secondary actions use ghost or text variants?
- Is the CTA label specific and action-oriented ("Save changes", not "OK")?
- Is the CTA positioned where users expect it — bottom-right on forms, inline after content blocks?
### Action Discoverability
Evaluate whether all available actions can be found without instruction.
- Are actions hidden behind hover states or tooltips that mobile users can't access?
- Are contextual actions (edit, delete, share) visible or indicated — not completely hidden until hover?
- Are empty states actionable — do they tell the user what to do next?
- Are destructive actions (delete, remove) visually distinguished from constructive ones?
## Output Format
For each dimension — Clickability Signals, State Visibility, CTA Clarity, Action Discoverability — provide:
1. **Observation** — what you see (neutral, factual)
2. **Problem** — what is broken and why it matters
3. **Fix** — a specific, actionable change
```
