## Decision tree

Run this before any web quality, performance, or accessibility audit:

1. **Is an Osmani skill already installed?**
   Check: `~/.design-agent-skills/skills/web-quality-audit/SKILL.md` exists (representative skill).
   - Yes → invoke the specific skill by name and proceed
   - No → go to step 2

2. **Do you have shell access?**
   - Yes → install the specific skill below, then invoke it
   - No → show the install command; in Claude Code, send it as a chat message starting with `!` — add `-g` for global install or omit for project-only

## Install command

```bash
# WCAG compliance, screen reader, keyboard navigation
npx skills add addyosmani/web-quality-skills --skill accessibility

# Lighthouse-style: performance, a11y, SEO, best practices
npx skills add addyosmani/web-quality-skills --skill web-quality-audit

# LCP, INP, CLS-specific optimizations
npx skills add addyosmani/web-quality-skills --skill core-web-vitals

# Loading speed, runtime efficiency, resource optimization
npx skills add addyosmani/web-quality-skills --skill performance

# Search engine optimization, structured data
npx skills add addyosmani/web-quality-skills --skill seo

# Security, modern web APIs, code quality
npx skills add addyosmani/web-quality-skills --skill best-practices
```

## Invoke after install

- `web-quality-audit` — "Lighthouse audit", "web quality"
