# ux-audit

This skill tests a live web app through browser interactions to catch usability, behavior, accessibility, and layout issues. Use it to review a release or walk through the app’s pages.

## What it does

ux-audit operates the app as a user would: it enters data, clicks controls, exercises scenarios, and records evidence. A static page inspection cannot produce an audit verdict. Each finding includes reproduction steps, an evidence path, and a suspected code location.

The workflow covers setup, page and element discovery, interactive walkthroughs, visual review, stress scenarios, verdict, and verification after fixes. It also runs axe-core checks and assesses LCP, CLS, and INP. Console errors, network 5xx responses, layout collapse, and accessibility violations can fail the audit.

The audit needs a persona and a browser tool. An authenticated app requires Chrome MCP with a logged-in session; Playwright MCP works for public sites. Without the right browser tool, the audit stops. A walkthrough without recorded interactions cannot receive a passing verdict.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill ux-audit -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill ux-audit -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill ux-audit -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jezweb/claude-skills ux-audit
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill ux-audit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/jezweb/claude-skills --path plugins/dev-tools/skills/ux-audit
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill ux-audit -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/jezweb/claude-skills/tree/HEAD/plugins/dev-tools/skills/ux-audit/SKILL.md

## When to use it
- catch bugs that appear only after clicks or data entry
- exercise pages and controls through user scenarios
- check accessibility with axe-core
- record reproduction steps and likely code locations
- retest affected areas after changes

## Example prompts
- Audit this app as a first-time user and test its main workflows.
- Walk through every page, interact with its controls, and find behavior bugs.
- Check the interface before release, including accessibility, performance, and stress scenarios.

# UX Audit

Walk through a live web app AS a real user. The audit is **interaction-first** — typing, clicking, sending, watching, screenshotting. A static DOM sweep cannot produce a verdict.

## Verdict states

The audit ends in exactly one of:

- **Pass** — Critical = 0, High = 0, all hard gates green, Interaction Manifest complete.
- **Conditional Pass** — Critical = 0, High = 0, all hard gates green, but Medium/Low present.
- **Fail** — at least one Critical or High finding, OR a hard gate red.
- **Incomplete** — Interaction Manifest missing required entries, a phase wasn't run, OR the audit-the-audit meta-check fires (manifest timestamps clustered < 0.5s apart, screenshots fewer than 2 × routes, console reads fewer than 1 × routes, Phase 3 took < 1m for an exhaustive audit). Not legal to upgrade to Pass even if everything observed looked fine.

If the work doesn't include a complete Interaction Manifest, the only legal verdict is **Incomplete**. "It looked OK" is not Pass. A clean Pass with implausible timings is rejected — the agent must redo the audit with real interaction.

## Hard gates

These auto-fail the audit. They cannot be downgraded.

| Gate | Threshold | Severity if violated |
|------|-----------|----------------------|
| Console errors during walkthrough | > 0 | Critical |
| Console warnings during walkthrough | > 0 | High |
| Network 5xx | > 0 | Critical |
| Network 403 / 404 on authenticated pages | > 0 | High |
| Layout collapse at any tested viewport / pane combo | > 0 | High |
| axe-core Critical violations on any audited page | > 0 | Critical |
| axe-core Serious violations on any audited page | > 0 | High |
| LCP on representative route (pragmatic budget) | > 4.0s | High |
| CLS on representative route | > 0.25 | High |
| INP on representative route | > 500ms | High |
```
